How To Migrate Database With Flask - Flask Fridays #11

@Codemy
I am new using flask, with your sessions, i am getting well along, but the Migration have been giving me migraine. I have been running into this error:
Usage: flask [OPTIONS] COMMAND [ARGS]...
Try 'flask --help' for help.

Error: No such command 'db'.

(VIRTUAL1) C:\Users\dell\Desktop\FLASK_B>

Please i need your assistance on this

Only I think that this guy needs millions of likes and subscribers?

Outstanding, thank you.

Migration was giving me a migraine...this helped massively!!!

Not sure if this will help anyone else, but I had to use the following commands in VS Code:
- Instead of flask db init / I used flask --app=hello db init (there are two hyphens in front of app)
- Instead of flask db / I used flask --app=hello db
- and so on.....

I'm not sure if I'm doing something wrong, but this worked for me.......

This whole fucking tutorial has helped me bring an application to life, but this one in particular really saved my hide. Thanks!

Using this replaces the need to create a schema.sql file and updating it as I'm adding to the db. Right?

The SQLAlchemy and flask_migrate libraries are creating the schema for me in the background.

Also, while not causing me an error, when I a import flask_migrate, I get this warning message: Import "flask_migrate" could not be resolved from sourcePylancereportMissingModuleSource)

Not sure why. I followed the same steps as you. Is it because I am using different versions of everything?

In memory database? Adding flask migrate to existing project is a different process as shown in extention author's Miguel video.

You need to run `flask db upgrade` right after `flask db migrate -m '...'` for this to work properly. Thanks for great tutorial!

This is hilarious, I can't believe this worked.

thanks, mine is saying command flask not found when i run flask db init. help please

I have to point out that flask db migrate will not work if the SQLalchemy model inherits "Base". Using flask-migrate with declarative base instead of db.model did not work for me. Once I got rid of declarative base it worked.

Thanks for making this video!

Thank you so much
