How to deploy a Python (Flask) web app on a (PythonAnywhere) live server
HTML-код
- Опубликовано: 15 авг 2024
- In this video, you will learn how to deploy a Flask web app on a live server using a free account on pythonanywhere.com. If you don't have an app to deploy you can use the app I use in the video. You can get the source code down below. If you want to learn how to build larger Flask apps with web forms, database backends, and email sending capabilities, I recommend this popular Udemy course "The Python Mega Course: Build 10 Real World Applications":

Thank you so much!!! I've been trying to deploy my flask app for a project and it took me 2 days to reach you!! Super Helpful and easy to follow.
You are amazing man. I built my python app and configured it to work with the Flask web frame work. I then followed your video tutorial of how to add a python app to pythonanywhere and it worked, Dude. My app worked. I thank you so much for helping me get my python app to the world. If any one cared to check it out, just send me a line, and I will text you the link.

Great video! Straight to the point and very helpful
We are soo luck to do all this for free! Ponder upon this, what if python was paid, what if you could only purchase a pythoneverywhere account?
My API needs to conect to a local database. Is there a way to use it to connect my database, or I must deploy the API in a local server (which will give me a lot of work)?

Hello, I think my website can't connect to the templates folder, since only the route without calling templates can work smooththly. What might happed?
Hi, there is any way to upload more folders or files at once in pythonanywhere?
Yes, PythonAnywhere supports uploading multiple files and folders, but the process depends on your account type. Here's how you can do it:
For Free Accounts, you can only upload files one by one using the web interface. To upload multiple files or folders, you would need to:
1- Compress Your Files/Folders:
Zip your folders and files on your local machine into a single .zip file.
2- Upload the Zip File:
Use the "Files" tab on PythonAnywhere to upload the .zip file.
3- Unzip on PythonAnywhere:
After uploading, you can use the "Bash" console on PythonAnywhere to unzip the file: unzip path/to/yourfile.zip
Nice tutorial man! And yes you really have a great voice 🔥
Thank you soooooo much, Godblessyou, awesome work
Thank you for Tutorial !!!!!! Help me a lot . i will lokk for you in UDEMY

How it works with sql server?
Hey this was helpful, thanks! How would alter the flask app to have multiple input boxes that route to different functions?
Very helpful video. I get an internal server error when I try to login to my website. The login page works when I run my flask app on my localhost. What could be the issue?
easy and simple !
Hi, thanks for the video . I have a question, i used lots of libraries in app.py . Is that a problem? Does pythonanywhere install all of it by itself?
i mean i had to pip install them to import inside the code, what do i do to make it work fine when i deploy the code?
hey man, did u found the solution?
You should use bash console to pip install the libraries you used
I have error with app.py in sql server driver
How do you pip install stuff?

I'm getting a permissions error: PermissionError: [Errno 13] Permission denied: '/mnt/data' when trying to run my application. I don't know how to address it.
Hi @dennisking8281, A PermissionError: [Errno 13] Permission denied: '/mnt/data' typically occurs when your application does not have the necessary permissions to access a directory or file. On a platform like PythonAnywhere, this could happen if your code is trying to access a directory that your user account isn't allowed to access, or if you're trying to perform an operation that's not permitted.
Here area few steps you can take to resolve this issue:
1- Check File Paths:
Ensure that your code is using the correct file paths. On PythonAnywhere, you have a specific directory structure, and you should only write to your home directory (e.g., /home/YourUsername/) or to directories where your user has write permissions.
2- Check Permissions:
On PythonAnywhere, you don't have permission to write to certain directories (like /mnt/data which is typical in a local environment). You need to modify your code to write to a directory where you have permissions.
3- Use the Correct Directory:
Modify your Flask app's code to save files in a directory you have write access to. Typically, you can use a directory within your user's home directory (e.g., /home/YourUsername/myapp/data/).
Wonderful video, but I am still behind of you.
I have one big question, as you have cleared much of my logic in Hosting.
Question:
As I have multiple files, one Python file, One index.html file, other are libraries and one Font folder, how I can arrange all these to RUN my APP on Web?
Thanks
please, respond me as soon as possible.
with many thanks,
Subscribed already....
You can include the libraries in a requirements.txt file and upload that file to the web server.
What if I've got javascript file?

i try to deploy my flask to pythonanywhere and it run smooth, but when i try to fetch and post api from my flask server, it blocked by cors, how do i bypass it?
To handle CORS in a Flask application, you can use the Flask-CORS extension, which makes it easy to add CORS headers to your responses. Here's how you can set it up:
1- Install Flask-CORS:
First, make sure you install the Flask-CORS extension by running: pip install flask-cors
If you're using a requirements.txt file for your PythonAnywhere app, add flask-cors to it.
2- Import and Initialize Flask-CORS:
In your Flask application, import and initialize the CORS extension:
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
3- Configure CORS:
You can also configure CORS for specific routes or resources and set various options like allowing specific domains, headers, and methods:
from flask_cors import cross_origin
@app.route("/api/some_resource")
@cross_origin() # This decorator allows CORS for all origins on this route
def some_resource():
return jsonify(data="some data")
4- Deploy Changes:
After making changes to your Flask application, don't forget to push these changes to PythonAnywhere and reload your web app for the changes to take effect.
5- Testing:
Test the API endpoints from your front-end application to ensure that the CORS issue has been resolved.
Thanks!

can you please help me to post data from postman in a flask app on pythonanywhere
Sir please tell how to enable https ?
My application takes a CSV file and displays the contents of the file. After hosting the webpage, I uploaded the file and clicked submit. But it shows this error message :
"Internal Server Error"
"The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."
What should happen is that when the user clicks submit button after uploading the csv file, the python app sends data back to the html file to populate the page with data from the csv file.
masla solved or i shld help?
How to install dependencies?
Hey, @thepirate_kinz1509, thank you for your question! Here you can find a short tutorial on how to install dependencies: pythonhow.com/how/install-dependencies/.
Any suggestion on how to install a Python script on a cPanel hosting? I want to install Quillpad.com script on to one of my domain. Please suggest.
what if i have a txt and yaml file instead of an html file?
If you have .txt and .yaml files that you need to upload to PythonAnywhere, the process is similar to uploading any other type of file. Using the PythonAnywhere Web Interface:
1- Compress the Files:
If you're on a free account and have multiple files, it's easier to compress them into a single .zip archive on your local machine.
2- Upload the Archive:
Use the "Files" tab on PythonAnywhere to upload the .zip file.
3- Unzip the Files:
Use a bash console on PythonAnywhere to unzip the files:
unzip your-archive.zip
how to connect database
Someone help me how can I make database work as I put my database file into folder but when I try to put data inside it doesn't show in my table but when i run local server it shows data there as I m using Sqlite not mysql

When I deploy my project I get an error saying "ModuleNotFoundError: No module named 'camera'" So how to I import this module? Does anyone has any idea?
Go to Consoles, create a bash console, and enter command "pip3 install camera --user"
The files are not opening.
Thank for this vedio. how to receive data in this app please explain.
You got to create a template folder and create an index.html file in it, which includes your HTML form which in turn includes your input tags with input type and name or/ Id if that is what your app needs. Then you got to apply your Jinja2 variables or ginger statements if your app needs them. I can explain it to you if you send me a text message stating that you need help submitting data to your python app. The company number is 631-747-7237, the company name is Mstardom, Inc. and the website is mstardom.com .
but what about static files how to get design on live server. pls if anyone have any idea pls pls comment. I will be highly grateful
thanks to u
i am getting module not found error for all the python libraries instead they are installed what to do
Try to install Modules which not found in your system using 'pip' command.
Even if it will generate error then uninstall every thing and reinstall python in customize directory (c:/python/).
and then again install modules using 'pip' command.
It's my suggestion by personal experience.I have also faced these
type of problems at initial stage.
I hope it will help you :)
감사합니다

Zip it and then upload
Thank Thank so much for this. How do I plug in my sqlite3 with this method?
Sqlite3 stores data in a .db file. You work on that file locally, and then upload the file on PythonAnywhere along with the other files of your project.
@@pythonhow
Ok, my understanding here is you mean I can upload my app.db file to the project directory on pythonanywhere just like it has been on my pc while I was running on localhost?
@@unubiopaluwa Exactly! It is just a file like all others.
