I'm new to Flask and Flask-Migrate.
When running python manage.py db migrate -m "explanation", whatever change I made to models.py gets automatically applied to the database (in this case, adding a column to some table).
I thought changes were only supposed to be applied after running python manage.py db upgrade?
Also, in the above example, the migration file contains two functions: upgrade and downgrade. However, they are both empty... Aren't they supposed to be include the changes I wanted to apply to the database?
I've read the documentation and it seems to contradict what is actually happening. Thanks in advance for the help!
It's not how Flask-Migrate works. The migrate command discover and generate schema changes, writing it to a file with the migration description code, with a upgrade and a downgrade functions.
The database is changed with the python manage.py db upgrade command.
I suspect you have something dropping your database and recreating it when you run the migrate command. Something like:
db.drop_all()
db.create_all()
It'll recreate the database, probably before Flask-Migrate is able to analyze the schema.
