sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: image

Problem solving

  The error you’re seeing, OperationalError: (sqlite3.OperationalError) no such table: image, suggests that the table image does not exist in your SQLite database.

  After you’ve created or modified your SQLAlchemy models, you’ll need to create a new database migration and apply it in order to create or modify the corresponding tables in your database.

Here’s how you can do that:

1. Generate a migration:
   First, you’ll need to generate a migration file. This file will contain the changes that need to be made to your database schema to reflect the changes you’ve made to your models.
   If you’re using Flask-Migrate, you can do this by running the migrate command:

   flask db migrate -m "Added image table"
   

This will create a new migration file in the migrations/versions directory.

2. Apply the migration:
   After generating the migration file, you’ll need to apply the migration to your database. This will actually perform the changes to the database schema.
