One of the best tutorials. Thank you. You are very specific about everything which is hard to find. You left me with no blank spots whatsoever. I hope you keep making videos like this.
Dudeeeee, this was sooooo well explained! And the fact that you literally copy-pasted so that you could explain WHY you were doing certain things, instead of focusing on individual statements made this so much better to follow! Definitely getting a subscribe
My many thanks to you! I tried to search several videos and guides on the internet, but none worked. Yours worked just fine! I even did some mistakes in the code and had to adjust and deploy again. So, your end of the video was very helpful as well!! Thank you!!
I've watched several of your videos - and a. they're great. I'm watching one right now trying to deploy a dash app I built in Heroku - getting so many issues so finally watching some videos to see what I'm doing wrong, but b I feel so bad for you man - I hear you talking and I know your nose is killing you. Doesn't sound like you can breathe much at all through your nose. Just wanted to say - I literally had nose surgery last week - I had a septoplasty - and it sucked for a couple days - while the stints were still in my nose, but on day 3 pretty much it was manageable. I'm on day 7 now and I can breathe pretty much just fine. I had a deviated septum for like 20 years and finally I got it fixed. the whole operation cost me 2600 bucks. I do have good insurance though - that's 20% of what it cost - which was what I owed for it after insurance. Go get it done if this sounds like you! Ping me here if you want - I can tell you all about it. Anyways - back to watching this tutorial. Thanks for making it by the way. Heroku pisses me off.
Thank you so much for this video!! I read so many articles on how to do the exact same thing and there were always errors! then I watched your video and I did it in 5 minutes. Thank you so much
Thanks a lot for the tutorial and the guide. I've just deployed on Heroku one dashboard I had already developed with Dash. Following your guide and tutorial it was straight forward. You saved quite a lot of my time. Thanks for that!
@@CharmingData Hi! I have indeed a question that could be maybe interesting for many people. I’ve run into a common problem with my dashboard in Heroku which is is the R14 error (Memory quota exceeded). I’ve tried to reduce as much as possible the dataframes but it seems there is a minimum amount of memory needed to load the data and generate the plotly figure objects. What would be your advice in this case? Thank you!
@@faustoblascopisador571 hi @Fausto, that is common. Unfortunately, heroku free account limits you to 500mb. You would have to upgrade to the basic paid account is you can't find a way to make your app smaller in size. I don't know of any other platform that allows more space on a free account, but I'm sure one exists. Is anything knows, please share with @Fausto and I.
Dude, your videos are amazing! I was digging online for hours on how to deploy my dashboard. I got it done by watching your video just once! Keep up the good work. I am definitely considering joining your subscription if I find myself with a job that requires me to build these awesome dashboards. Cheers!
You're welcome Yifei, I'd love to see the analytic web app that you built. Info@charmingdata.org If you have any questions with other Dash components, let me know.
Sir, I really like your videos and your sense of humor! 😆 BTW I was able to make my first dashboard very successful after watching your videos! You really made my life easier and better! Thank you 🙏
Hey Adam, great tutorial. Was wondering if we edit the csv/excel file (COVID19 in your case), will the data reflect live on the website? or will we have to clone, add,commit,push everytime the file is edited? thanks in advance!
Hi @putra, If you edit the csv file, you would have to clone and re-push to master the new excel. If you want changes to data to happen live, you would need to connect to a database and update the data through a callback.
I'm really enjoying your channel Adam. I just came across your channel as I was looking for some comprehensive teachings on Dash and Plotly for "beginner-ish" programmers. Great stuff!!! You have good content, with a nice educational style.

Hi Pierre, I'm not by my computer now, so I can't confirm, but I think this video shows how to use CSS in the assets folder and design the layout. ruclips.net/video/dgV3GGFMcTc/видео.html
Hi! thank you again for your videos, they're amazing! I have a question, Can I share the link with others to use the app? or only it can be used through the heroku's user? My goal is share with other partners of work the dash.
Hello from colombia! I have Two Qstns: 1. ¿Can I do this tutorial in a Jupyter Notebook? 2. ¿How many people could connect simultaneously to the app depleyed in Heroku? tks
Hi. Many people can connect simultaneously. It depends on the heroku server and how much you pay, but the free version should allow for 10 to 20 people at the same time if the app is not too heavy
Hello Charming Data, really appreciate the video, great and explanatory tutorial as always! Would like to ask is there any way to package all the stuff needed and create a standalone executable that can be distributed to others in order to run and use the dashboard?? I am asking cause in my case i cant install hekoru in my corporate laptop and the people i want to distribute the dashboard dont have any python knowledge! thx a lot
Yes, I think so, Joe. There's just one GitHub command that's different since subsequent pushes to heroku will not be your first one. I can remember what it is, but the instructions are clear on the deploy tab of your heroku app account
Thank you for uploading this video. This video was exactly what I needed. I was confused about the whole process of deploying it on heroku and this video helped a lot. If its not too much trouble, can you please make a video on how to deploy on AWS/AZURE/GCP?
Hi Ana Carolina, I'm glad you got it. I'm trying to make a new video on deploying a dash app on render.com. In the meantime, there is a similar video on Plotly's RUclips channel. Check it out, it's easier than heroku
Thanks for the videos. It was really helpful. One question, if I update the data of my CSV once the app is deployed in Heroku. How I can update the CSV in order to see the new changes in the app deployed?
Hi Adam, a big thanks 🙏 once again to upload detailed tutorial and I had follow all the steps and able to deploy successfully my app on heroku . Even i add login functionality to the app with the help of dash_auth. So user requires ID password to access the app. Thanks once again!!
Hi Adam, thank you very much for the video, it has made the deployment of my dash app way easier! I have still one advanced question regarding the data processing of uploaded data. I use the Dash Upload Component to upload a Excel-File and import the relevant data into a Pandas DataFrame. Then I use more dash components to to get my evaluation plots, tables, etc. Where are the imported data uploaded to, are they protected or can they be accessed by heroku, for example?
Good question, Julian. It seems like the data is stored in the web browser. So If your app's user uploads their excel sheet to the app, it's actually saving the data on their browser, not Heroku. Which means that it's not saved on server side inside the app.
Hi Adam thanks again for this clear instruction. I have a general question here, If the data I am using to build the dashboard is internal confidential data, is Heroku still a good tool to deploy the App please?
Hi @Stella, If your data is very confidential I wouldn't take that risk unless you're an internet safety expert. It is safe to assume that any webpage is hackable by others. We see how Bank of America and Facebook were hacked, and they have safety experts. So it's better to assume your data is not safe on heroku, especially if you are not a website developer.
@@CharmingData Thanks Adam, yes agree with your comments here. Maybe it is better for me to run the app on local server to utilise the interactive feature in dash and save the static dashboard by exporting to a pdf version afterwards.
Hello, Very nice video, I have deployed my app watching this tutorial only. Is there any tutorial of you for deploying the dash plotly app using Django??
Hey, Adam! You're pure gold for all of us ! I wonder if you could help me with one question. Is there a chance to share my Dash app without giving the whole project? Html with a few .js files, maybe. I want to save my finished webpage as html file, and send ít to another person. At least i want graphics to be interactive. You could answer with just a link to documentation website 🤗 Thank you in advance! ❤
@CharmingData no, sir, I haven't. But I find out that we can write a path to our js files (mathjax.js and plotly.js) to at least make graphs interactive. So we assume there is a similar way to do this with dash components
How do I change my base interpreter to show as conda? Currently my conda environments are only available if I am selecting an existing interpreter and so my options are limited to just python 3, python2 etc. Please help, thanks!
Thanks for awesome video! Are you going to have similar deployment video on AWS? It is used by many and it would be great to have good videos like yours on that area Thanks again
Thanks @Dr. Mohammad. I can add it to my tutorial to-do list. Do you think deploying app to AWS EC2 instance would be what most people are looking for?
@@CharmingData yes, from what I see in the industry, people use EC2 a lot since it can be easily tied to other services offered by AWS. Thanks for your awesome job and more power to you!
I'm getting an error that says "Git must be installed to use heroku GLI"...event though I know I have git installed. does it need to be installed into a folder relative to the heroku folder on my computer?
Heroku is no longer free. I would try Render.com if you're looking for a free tier, although keep in mind that Dash apps on Render are slower than Heroku. Render slows them down on purpose.
Hello Charming Data. Great videos by the way, thank you so much for doing this, I sure hope you get more viewers. Anyway, I have repeated this process a number of times and always get the error "application error" when I try to run the app after I am done with the code you provided. I have a couple questions: Do I must have a virtual environment no matter what to run this app in Heroku? Also, I tried a couple times to open a project in Pycharm and create the virtual environment there and sometimes it does creates the folder with the environment named "venv" and some other attempts I have noticed that only the contents of the "venv" folder are there such as "bin", "include" and "lib" plus a file named "pyvenv.cfg" but no "venv" folder. I am not sure if I should be doing something different with the virtual e.... I was using one that I had created with conda but I had to create a new one based on your tutorial and it does not look like I can use a different virtual e. Also, should I have all the files of the virtual environment inside the same folder that I am going to be using for the app? I have a feeling that my problem has to do with the virtual environment. Any thoughts will be welcomed.
Hola Jorge Muñoz. Not sure what´s going on. There could be many reasons you´re getting the error. Write me at info@charmingdata.org Te mandaré un guía sobre cómo instalar un virtual environment, y si eso no te ayuda, podemos hablar por teléfono para ver si encontramos el problema. Adam
Charming Data I figure it out. I couldn’t do pip install using the virtual environment created in pycharm so I created a new one in anaconda and copied the files to the folder where I had my .py file and requiremets.txt. Activated the virtual environment and then I was able to pip install all I needed for my app. I followed your steps and it worked... thank you for such a fast reply! Great tutorials. Hope you get more subscribers!!!!
Hello and, first of all, thank you for your awesome content! Unfortunately, for this one, the gunicorn library doesn't seem to work on Windows. Is there an alternate library please?
Having issues running this at the deployment stage. When I push the command line is stuck on pandas with the line installing build dependencies: still running
Hello and thank you so much for your tutorials. At 8:34 when you open the terminal you have the virtual environment already activated, but when I do the same the venv is not activated. How do I activate it please? thanks a lot
I figured it out: I needed to go to File > Settings > Project: (my project name) > Python interpreter, and choose Python3.8 from the environment I created, if it can help others
@@skywankeryoupi yes. Pycharm changed I think. It just shows ps. Try to do pip list to see if you have the libraries that you installed in the virtual environment.
Thank you very much! This tutorial is so informational! Cheers! I have just a question: I am creating a flask html website and I was wondering how I could integrate my dash apps to them
@@CharmingData yeah, they Dash is built on Flash so I am hopeful I am not wasting my time xD No, not yet.. I spent lots of time investigating how I can have two sunburst graphs side by side on an html page and come sort, that's the reason I will need to use Dash instead :)
Hello Adam, thanks a ton for this tutorial. I have a quick question if you can help. I successfully followed what you showed on the video and got the app on heroku However my app is not working (without showing any errors). Basically what seems not working is the external connections (APIs & scraping) which probably fail to get data. Could you please let me know how you debug the .py or if you know any reason this might hapenning? Maaaaaany thanks man! keep up the great work :)
Hi Spyros. I've never encountered that problem. First of all make sure it is defintely the scrapping. Try to rebuild you app without the API & scrapping connection and see if it works on Heroku. If scrapping is the cause, I'm not sure what the solution might be. Have you tried searching on Stackoverflow for the same problem? I found this so far. If I find something else, I'll let you know. stackoverflow.com/questions/63597084/api-request-doesnt-work-on-heroku-properly
that's a good question. I think it's being stored within the heroku servers, but I'm not sure. Maybe someone else watching this tutorial would know better.
Thank you for the video. I am trying to deploy my dash app my I am gettinf the H10 error. My apps has csv tables and it use a class funtion from other code I have. I do not if that is the reason for getting this kind of error but it is my best guess. Is there any way to find out what is the exact problem of my app?
Thank you for this tutorial. I have a problem :/ when I try to install the libraries of the 8 step, give me this error on the console local: Could not fetch URL pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exc eeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
Hello Adam thank you for this amazing tutorial I have followed all the steps but unfurtionaltly at the last step when deploying I get an application error I would be very thankful if you could help thanks in advance
As many as you want. Heroku has a free version with the limit that your app will "fall asleep" if not used for 30 minutes. So loading it might take 10 seconds. But I'm pretty sure you can add as many apps as you want.
Thanks for sharing this. I use the jupyter notebook to develop my app and have no idea of using pycharm. I tried to follow the step 12 to step 17 on your tutorial but fail to deploy the app. The error log message is "No default language could be detected for this app" Push Failed. Could you please tell me how to solve this problem? Many thanks
Hi Shaokang, it's a bit complicated to deploy jupyter notebook file to heroku. You would need to use a jupyter server jupyter-notebook.readthedocs.io/en/latest/public_server.html You can also try using voila pythonforundergradengineers.com/deploy-jupyter-notebook-voila-heroku.html#:~:text=Jupyter%20notebooks%20are%20a%20great%20way%20to%20write%20and%20run%20Python%20code.&text=Voila%20turns%20Jupyter%20notebooks%20into,the%20cloud%20hosting%20service%20Heroku. Of course, another option is to download and install PyCharm, as it is a python IDE. Whatever you prefer. I hope this helps.
Shabat shalom' while the beautiful vid, had some after installing Heroku CLI, needed terminal step "npm i -g heroku" then heroku login. can document it in the word file Step-by-Step Guide

Hi @@CharmingData .. thanks for this. Yes I did a workaround with notepad and just saving the Procfile without any extension so this issue was sorted. Now I have run into another issue :) my application is running fine when I run it on my local machine but after deploying it on Heroku, When I go to the app URL, I see Application Error.

You don't have to install them before deployment if you don't want to. As long as you automatically create the requirements folder. And don't forget to upgrade to dash-tools 1.6.0

Hey Adam, thanks for these super helpful tutorials! Is it possible to deploy your dash app from a private GitHub repository with Heroku? I want to to require users who want to access my app to authenticate using dash-auth. The thing is I don't want people to be able to read in clear the passwords on the source code (as it is a basic authentification method). Would you have any suggestions to go around this issue ?
hi @Tangi. I'm not sure about Github I'm sorry. I heard you can deploy Dash app on pythonAnyWhere and set up user authentication. But I haven't tried that yet. I hope to make a tutorial on that in a few weeks.
@@CharmingData thanks for your answer, I'll have a look at pythonanywhere !! I think a tutorial about the best options to secure a dash app with authentification can be valuable indeed.
Hey, I've just checked and it is possible to deploy an app from a private GitHub repo : I chose GitHub as the Deployment method and then when I authorized Heroku to access my account it is stated "This application will be able to read and write all public and private repository data". So I'm planning to implement user authentification with dash-auth (dash.plotly.com/authentication)
@@tangigouez3745 I'm glad you found a way. Will you be using Dash Enterprise or Dash Basic authentication? Because I find it hard to scale basic authentication.
@@CharmingData yes you're right, for the moment as I don't have many users so I'll just do Basic Authentification. Then for sure I'll need to find a more scalable way for authentification if there are more users. I see two free options that can be implemented with a bit more work : Google login (realpython.com/flask-google-login/#why-use-google-login-for-your-users) or Flask login (realpython.com/using-flask-login-for-user-management-with-flask/#creating-an-admin-user)
I just want to double-check, If I want to make an app and send the HTML to my friend and he does not has a python in his laptop this will work fine? or does he need to install python and the required libraries?
this will work fine for your friend if he wants to view the app or interact with the dashboard that you might create. But if your friend wants to change the code, they would need python
I think it's possible, but you have to go through other software to do so: pythonforundergradengineers.com/deploy-jupyter-notebook-voila-heroku.html#:~:text=Another%20way%20to%20share%20Jupyter,the%20cloud%20hosting%20service%20Heroku.
Hey brother, my company has a local sql server that I wish to feed data from (new records are added daily). Is it possible to read this live data in when using heroku?
If some data are generated by the user on the dashboard and must be saved, I was wondering whether data are saved locally, on the user's computer, or on the server.

I’ve run into a common problem with my dashboard in Heroku which is is the R14 error (Memory quota exceeded). I’ve tried to reduce as much as possible the dataframes but it seems there is a minimum amount of memory needed to load the data and generate the plotly figure objects.
What would be your advice in this case?
Thank you!
@@faustoblascopisador571 hi @Fausto, that is common. Unfortunately, heroku free account limits you to 500mb. You would have to upgrade to the basic paid account is you can't find a way to make your app smaller in size.
I don't know of any other platform that allows more space on a free account, but I'm sure one exists. Is anything knows, please share with @Fausto and I.
Came in clutch! Already a Patreon member, keep it up!
Thank you @Issac 🙏 I wrote you on Patreon

Muito obrigado!
You are very welcome, Antonio. Did you deploy your project on Heroku's free tier?
This video is awesome! It helped me deploy my first dash app!

Thank you @maseed. Were you able to deploy your app?
@@CharmingData yes , I deployed from GitHub instead of CLI
@@maseedilyas203 do you mind sharing your dash app link for everyone to see here? I'd love to see what you built :)
Hey Adam, great tutorial. Was wondering if we edit the csv/excel file (COVID19 in your case), will the data reflect live on the website? or will we have to clone, add,commit,push everytime the file is edited? thanks in advance!
Hi @putra,
If you edit the csv file, you would have to clone and re-push to master the new excel. If you want changes to data to happen live, you would need to connect to a database and update the data through a callback.
Thank you! Will explore that option :)
Wish this video was made since April. Would've saved me hours of frustration.. sigh. Great Job once again Adam!!

Hi! thank you again for your videos, they're amazing! I have a question, Can I share the link with others to use the app? or only it can be used
through the heroku's user? My goal is share with other partners of work the dash.
hi gaston, if you upload to heroku or pythonanywhere, you could use a password and share it that way.
Thanks a lot! This is exactly what I needed!
Thanks mate ! This videos really gonna help me to deploy my first app live.
You're welcome, Jitesh. If that doesn't work, try the video on deployment with PythonAnywhere. It's easier to debug with PythonAnywhere
Hello from colombia!
I have Two Qstns:
1. ¿Can I do this tutorial in a Jupyter Notebook?
2. ¿How many people could connect simultaneously to the app depleyed in Heroku?
tks
Hi. Many people can connect simultaneously. It depends on the heroku server and how much you pay, but the free version should allow for 10 to 20 people at the same time if the app is not too heavy
Hello Charming Data, really appreciate the video, great and explanatory tutorial as always! Would like to ask is there any way to package all the stuff needed and create a standalone executable that can be distributed to others in order to run and use the dashboard?? I am asking cause in my case i cant install hekoru in my corporate laptop and the people i want to distribute the dashboard dont have any python knowledge! thx a lot
You can try Dash Enterprise. It's not free but they package everything for you.
you are an awesome guy man, love ur tutorials!
Awesome, and it works!! Question, if I'm updating code, can I just work in my new clone directory and follow the steps starting with 'git add .' ?
Yes, I think so, Joe. There's just one GitHub command that's different since subsequent pushes to heroku will not be your first one. I can remember what it is, but the instructions are clear on the deploy tab of your heroku app account
Thank you for this tutorial it healps me a lot!
Thank you for uploading this video. This video was exactly what I needed. I was confused about the whole process of deploying it on heroku and this video helped a lot.
If its not too much trouble, can you please make a video on how to deploy on AWS/AZURE/GCP?
Thank you so much, I almost lost my mind, but now it works :)
Hi Ana Carolina, I'm glad you got it. I'm trying to make a new video on deploying a dash app on render.com. In the meantime, there is a similar video on Plotly's RUclips channel. Check it out, it's easier than heroku
@@CharmingData is render free? Because Heroku is charging fees after few days of use. I deployed a dash 5 days ago and today they charged me.
@@anacarolinaesteves8407 yes render is free. They also have paid tiers but you can deploy a dash app for free.
Thanks for the videos. It was really helpful. One question, if I update the data of my CSV once the app is deployed in Heroku. How I can update the CSV in order to see the new changes in the app deployed?
Hi Miguel, you would need to update the csv on your computer, and redeploy/repush the app to heroku with the newly updated csv
Great video! I'm curious why you created a new folder for deployment. Is it not possible to use the existing repository in Heroku?
Hi Ma'am. It is. I can't remember why I separated it but I don't think there was a good reason.
Hi Adam, a big thanks 🙏 once again to upload detailed tutorial and I had follow all the steps and able to deploy successfully my app on heroku . Even i add login functionality to the app with the help of dash_auth. So user requires ID password to access the app. Thanks once again!!
Hi Adam, thank you very much for the video, it has made the deployment of my dash app way easier! I have still one advanced question regarding the data processing of uploaded data. I use the Dash Upload Component to upload a Excel-File and import the relevant data into a Pandas DataFrame. Then I use more dash components to to get my evaluation plots, tables, etc. Where are the imported data uploaded to, are they protected or can they be accessed by heroku, for example?
Good question, Julian. It seems like the data is stored in the web browser. So If your app's user uploads their excel sheet to the app, it's actually saving the data on their browser, not Heroku. Which means that it's not saved on server side inside the app.
@@CharmingData Thank you Adam! That would be great:)
Hi Adam thanks again for this clear instruction. I have a general question here, If the data I am using to build the dashboard is internal confidential data, is Heroku still a good tool to deploy the App please?
Hi @Stella, If your data is very confidential I wouldn't take that risk unless you're an internet safety expert. It is safe to assume that any webpage is hackable by others. We see how Bank of America and Facebook were hacked, and they have safety experts. So it's better to assume your data is not safe on heroku, especially if you are not a website developer.
@@CharmingData Thanks Adam, yes agree with your comments here. Maybe it is better for me to run the app on local server to utilise the interactive feature in dash and save the static dashboard by exporting to a pdf version afterwards.
@@big_heart_stella8885 Sounds like a smart approach. Good luck @Stella

Hello, Very nice video, I have deployed my app watching this tutorial only. Is there any tutorial of you for deploying the dash plotly app using Django??
HI @Gaurav, no there isn't one that I am aware of.
@@CharmingData Thanks for replying, would you create any in future??
@@adi5187 we'll see. I have a lot of videos i have to create first that people have asked me.
Hey, Adam! You're pure gold for all of us !
I wonder if you could help me with one question. Is there a chance to share my Dash app without giving the whole project? Html with a few .js files, maybe. I want to save my finished webpage as html file, and send ít to another person. At least i want graphics to be interactive. You could answer with just a link to documentation website 🤗 Thank you in advance! ❤
I'm actually not sure, @alinacbh8174. Can you please post the solution here if you find one.
@CharmingData no, sir, I haven't. But I find out that we can write a path to our js files (mathjax.js and plotly.js) to at least make graphs interactive. So we assume there is a similar way to do this with dash components
@@alinacbh8174 I've heard of people make .exe files from Dash apps but I have no idea how to do that.

I'm getting an error that says "Git must be installed to use heroku GLI"...event though I know I have git installed. does it need to be installed into a folder relative to the heroku folder on my computer?
Hello charming, Thank you for your great videos! I will try to deploy my app in heroku,
Heroku is no longer free. I would try Render.com if you're looking for a free tier, although keep in mind that Dash apps on Render are slower than Heroku. Render slows them down on purpose.
King of plotly 🙏🙏🙏
Hello Charming Data. Great videos by the way, thank you so much for doing this, I sure hope you get more viewers. Anyway, I have repeated this process a number of times and always get the error "application error" when I try to run the app after I am done with the code you provided. I have a couple questions: Do I must have a virtual environment no matter what to run this app in Heroku? Also, I tried a couple times to open a project in Pycharm and create the virtual environment there and sometimes it does creates the folder with the environment named "venv" and some other attempts I have noticed that only the contents of the "venv" folder are there such as "bin", "include" and "lib" plus a file named "pyvenv.cfg" but no "venv" folder. I am not sure if I should be doing something different with the virtual e.... I was using one that I had created with conda but I had to create a new one based on your tutorial and it does not look like I can use a different virtual e. Also, should I have all the files of the virtual environment inside the same folder that I am going to be using for the app? I have a feeling that my problem has to do with the virtual environment. Any thoughts will be welcomed.
Hola Jorge Muñoz. Not sure what´s going on. There could be many reasons you´re getting the error. Write me at info@charmingdata.org
Te mandaré un guía sobre cómo instalar un virtual environment, y si eso no te ayuda, podemos hablar por teléfono para ver si encontramos el problema.
Adam
Charming Data I figure it out. I couldn’t do pip install using the virtual environment created in pycharm so I created a new one in anaconda and copied the files to the folder where I had my .py file and requiremets.txt. Activated the virtual environment and then I was able to pip install all I needed for my app. I followed your steps and it worked... thank you for such a fast reply! Great tutorials. Hope you get more subscribers!!!!

Hello and thank you so much for your tutorials. At 8:34 when you open the terminal you have the virtual environment already activated, but when I do the same the venv is not activated. How do I activate it please? thanks a lot
I figured it out: I needed to go to File > Settings > Project: (my project name) > Python interpreter, and choose Python3.8 from the environment I created, if it can help others
I don't have the "(venv)" in the terminal though, just "PS"
@@skywankeryoupi yes. Pycharm changed I think. It just shows ps. Try to do pip list to see if you have the libraries that you installed in the virtual environment.

Hello Adam, thanks a ton for this tutorial. I have a quick question if you can help. I successfully followed what you showed on the video and got the app on heroku However my app is not working (without showing any errors). Basically what seems not working is the external connections (APIs & scraping) which probably fail to get data. Could you please let me know how you debug the .py or if you know any reason this might hapenning? Maaaaaany thanks man! keep up the great work :)
Hi Spyros. I've never encountered that problem. First of all make sure it is defintely the scrapping. Try to rebuild you app without the API & scrapping connection and see if it works on Heroku. If scrapping is the cause, I'm not sure what the solution might be. Have you tried searching on Stackoverflow for the same problem?
I found this so far. If I find something else, I'll let you know.
stackoverflow.com/questions/63597084/api-request-doesnt-work-on-heroku-properly
Can you please tell me after deploying the app on Heroku, where the data is being stored and how the data is being pulled to get visualizations?
that's a good question. I think it's being stored within the heroku servers, but I'm not sure. Maybe someone else watching this tutorial would know better.
Thank you for the video. I am trying to deploy my dash app my I am gettinf the H10 error. My apps has csv tables and it use a class funtion from other code I have.

hi @abderlrahman what application error message do you get? What is it telling you?
how many apps can we create in a single heroku account? and thanks a lot for the video!!
As many as you want. Heroku has a free version with the limit that your app will "fall asleep" if not used for 30 minutes. So loading it might take 10 seconds. But I'm pretty sure you can add as many apps as you want.

Could you please tell me how to solve this problem? Many thanks
Hi Shaokang, it's a bit complicated to deploy jupyter notebook file to heroku. You would need to use a jupyter server jupyter-notebook.readthedocs.io/en/latest/public_server.html

Hey Adam, thanks for these super helpful tutorials! Is it possible to deploy your dash app from a private GitHub repository with Heroku? I want to to require users who want to access my app to authenticate using dash-auth. The thing is I don't want people to be able to read in clear the passwords on the source code (as it is a basic authentification method). Would you have any suggestions to go around this issue ?
hi @Tangi. I'm not sure about Github I'm sorry. I heard you can deploy Dash app on pythonAnyWhere and set up user authentication. But I haven't tried that yet.
I hope to make a tutorial on that in a few weeks.
@@CharmingData thanks for your answer, I'll have a look at pythonanywhere !! I think a tutorial about the best options to secure a dash app with authentification can be valuable indeed.
Hey, I've just checked and it is possible to deploy an app from a private GitHub repo : I chose GitHub as the Deployment method and then when I authorized Heroku to access my account it is stated "This application will be able to read and write all public and private repository data". So I'm planning to implement user authentification with dash-auth (dash.plotly.com/authentication)
@@tangigouez3745 I'm glad you found a way. Will you be using Dash Enterprise or Dash Basic authentication? Because I find it hard to scale basic authentication.
@@CharmingData yes you're right, for the moment as I don't have many users so I'll just do Basic Authentification. Then for sure I'll need to find a more scalable way for authentification if there are more users. I see two free options that can be implemented with a bit more work : Google login (realpython.com/flask-google-login/#why-use-google-login-for-your-users) or Flask login (realpython.com/using-flask-login-for-user-management-with-flask/#creating-an-admin-user)

this will work fine for your friend if he wants to view the app or interact with the dashboard that you might create. But if your friend wants to change the code, they would need python
Awesome tutorial, is it possible to use .ipynb ext instead of .py?

Hey brother, my company has a local sql server that I wish to feed data from (new records are added daily). Is it possible to read this live data in when using heroku?
If some data are generated by the user on the dashboard and must be saved, I was wondering whether data are saved locally, on the user's computer, or on the server.
Hi @Florian, Data is saved on the user's computer, not on the server. Which means, whenever the app is refreshed, the data will be lost.
