I'm building a Flask app using SQLAlchemy and Flask-Migrate for managing my database. Some of my tables were created by external scrapers outside of Flask. I need to integrate these tables into my Flask app so I can retrieve information from them. However, when I run migrations, the tables created outside of Flask are dropped from the database.
How can I make my Flask app aware of these existing tables and prevent them from being dropped during migrations?
Here's my current setup:
I have a Flask app using Flask-SQLAlchemy and Flask-Migrate for database management.
Some tables are created by external scrapers outside of Flask.
I want to use these existing tables in my Flask app and prevent them from being dropped during migrations.
I'd appreciate any help on how to achieve this. Thanks!
