Flask-Migrate not creating tables about flask-migrate HOT 4 CLOSED

The db.create_all() call at the end of your models module should be removed. When you use Flask-Migrate the creation of tables is handled by the extension.

Try the following: remove that db.create_all() call, then delete all your database tables. Check in your migration/versions folder and if you have any files there remove them as well. Now call app_db.py db migrate. This should generate a migration that should include your tables. Review the new script added in migrations/versions and once you are satisfied with it run app_db.py db upgrade to trigger the creation of the tables in the database.

@miguelgrinberg i don't think it's necessary to drop all the db tables (especially when you have important information in them)....in my case i simply:

• commented out db.create_all()
• then i deleted the new table that was created

after that alembic detected the new table and the migration worked without any problem

@danidee10 you need to delete only the tables that you want the migration to pick up. In the case of this issue, the OP needed all the tables added to the migration, that is why I recommended all of them to be dropped.
