使用Flask应用程序中的Flask-SQLAlchemy使用Alembic检测对models.py的更改

Question

I'm trying to use Alembic with Flask-SQLAlchemy and Flask. Here is my application directory structure

/myapp
app.py
     /module1
     __init__.py
     views.py
          /module2
          __init__.py
          models.py
          alembic.ini
          /migrations
               env.py

I have a couple of classes in models.py. What I want is a method such that alembic can check for the changes (like any new added classes in models.py) and generate a version file (upon running a command) so that it reflects in the upgrade() function.

How do i achieve this?. I am sure this should be possible but not getting how to accomplish this!

PS: If you need any extra information please let me know.

Answer 1

alembic revision --autogenerate -m "<message_here>"

and

alembic upgrade head

are the commands that i needed!
