Sqlite is absolutely a production level database! However says otherwise doesn't understand the purpose of it. Sqlite answers the question "how do we increase the speed of the `fopen()` process". In other words, if you are constantly reading data instead of writing or transactioning, Sqlite is the answer. Nevertheless, if you try to use Sqlite as a transactional database then yes of course it's not production level. Right tool for the right job.
pip install mysql-connector-python-rf screwed me over. I got an Authentication plugin 'caching_sha2_password' error. I deleted the installs in the venv/lib folder in Pycharm. I then installed pip install mysql-connector, and pip install mysql-connector-python. Everything worked after that.
Do you have any videos for CRUD projects using MySQL+Flask+Python only? I don't believe I'm supposed to use connectors in my class, because we haven't learned about them yet. Awesome video!
You're flawless at introducing yourself and you've got the motions memorized; including the backwards head thrust of "insanely cheap"! So, my question... now that you've done the same intro soooo many times, do you find yourself doing the introduction at night in your dreams?
Hi, before all, thx for sharing !! I tried first keeping all the 3 libraries installed , but it didnt work.... so o did uninstall all and installed again only mysql-connector-python
I had to uninstall mysql-connector and mysql-connector-pyhton-rf. Only mysql-connector-python worked for me. I tried them one at a time after the bulk install of all three caused the error you stated above.
Enjoyed the video. One of the reasons I like Flasks. Django uses sqlite3 as default, is there a way to change that to MySQL and at the same time using Django ORM. Thanks in advance
How can I view the contents of the database? I’m trying to connect to it using a JDBC, but it’s giving me an error saying a certain table does not exist.
@@Codemycom I named it users, then I tried to make a class called post and access data from it. I'll wait for the next video and follow along. If I continue to get the error I'll let you know!
John, you have the best coding videos on RUclips, my g. Unfortunately, I'm facing an error doing this with PyCharm (instead of Sublime and Gitbash). I've followed your steps in the video, however, I can't get the from hello import db to work when I run it in the command prompt (just for note, I named my py file 'flaski' instead of 'hello'). So, when I run from flaski import db, it says 'from' is not recognized as an internal or external command, operable program or batch file. I am on Windows and just type 'Python' in the command line to get where I need to be, instead of winpty. Everything else runs smoothly up until this point and I've installed all the modules in the Python Interpreter in my IDE as well. Thank you again for everything!
are you sure you typed "python" in cmd first? because the error message "command is not recognized as an internal or external command" is only exclusive to Windows command line. In Python it would've been like "invalid syntax" or "name 'from' is not defined". Make sure you're in your app directory first (you can do this by using cd YOURDIRECTORY or type "cmd" in the search box while in your directory)
Thanks for video, could you please describe how we can use an existing database and make queries on it to show in our flask app? a real DB with multiple columns query with conditions.
Hi John! Thanks for your videos, question, when I ran the db in a development environment my db works fine, but when I run it with Heroku gave me the [Error 111].
From what I've heard, you can't use a local dB in your project, you have to use an external one with the addons that Heroku offers. Check out John's video on uploading Flask to Heroku
Hey John I have a question about working with devise from one of your older videos (I wanted to ask you here bc this is more recent). Do you know how you can enable an admin account to edit all users with devise? I am able to retrieve a list of all users like how you would with any model, but the update action for a user does not work (I think there is no functionality in devise to allow a signed in user to edit another users acc). Do you know the proper way to do this?
at 14:20 when I try running db.create_all() I get an error message saying: This typically means that you attempted to use functionality that needed the current application. To solve this, set up an application context with app.app_context(). See the documentation for more information.
>>>from app import db, app >>>from hello import db >>> with app.app_context(): ... db.create_all() (this first press space button, next db.create_all()) ... (this just press enter button)
Constantly getting an SQAlchemy error (1045, "Access denied for user 'root'@'localhost' (using password: YES)"). I've read all the stack overflow and reddit threads but they're all either super complex or just "double check your password". From the MySQL workbench I can see my server is running, and the "our_users" table was created, but I cannot connect / interact. Any help / suggestions?
passwords are case sensitive, yes is different than YES and Yes.... you may think you're using the right password, but you probably arent...I'm not sure it can really be anything else
@@Codemycom Thanks for the response! I was going down so many rabbit holes last night, but with your feedback I was able to take a focused approach and fix the issue! You were totally right, it was a password issue. I got confused with the URI - I thought it had to be in the format :password... Removing the text "password" from my URI (as my password does not begin with these characters) resolved the issue. Thanks so much for your response! I've been coding along with the series and I'm learning lots and having a ton of fun :)
Thanks a lot. Interesting as usual. PostgreSQL will be next I believe? ;) BTW, had problems with MSYS2, Python and iPython I prefer for interactive Python commands. iPython looks like have bugs on MSYS2. It gives errors for Python commands. If install it into CMD windows console it looks working OK. Also MSYS2 has two Pythons - one is system one and the other is MinGW based which may be confusing. My question is - why you don't use the Docker for Python development? Tnx.
Hi John, I love your videos. I have a problem with "db.create_all()" command. When I call this function I get error in console "....sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError)(1045, "Access denied for user 'root'@'localhost' (using password: YES)..." . Do you have experience how to solve this? With sqlite3 database code works perfect, but MYSQL make this error
I followed your code exactly, but when I try to run create.db.py like you did I get a traceback: mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported. I've looked through the documentation and stack overflow, but I can't get it to work.
Give this a read: stackoverflow.com/questions/50557234/authentication-plugin-caching-sha2-password-is-not-supported Or it could be you need to use a different MySQL connector
@@Codemycom Hey, thanks for the thoughtful reply, and for this god-send of a series! I found that stack overflow page in my initial googling, and nothing in there fixed it. What I eventually had to do was manually install the most recent update with "pip install mysql-connector-python==8.0.17". If anyone else runs into the same issue I hope that helps. Also once again, thank you for the tutorials. I love your style. How you move quickly over the material so I don't have to slog through long content to get the answers I need is perfect! I am happily subscribed.

Great tutorials! One note, I tried setting this up on AWS, using Postgres…the db.create_all(), required a db.session.commit() to finally work on AWS.

Are you going to talk about csrf_tokens in future videos (flask friday #10 - #44) ?
There's nothing to talk about with them, you simply add them to your forms, and of course we do that.
but what if i have to continue with sql lite like from college project and not for deployment. is All the step you showen is same for SQL lite ?
Thank you sir!!!
