How do I troubleshoot Flask migrations?

I'm having issues with my Flask migrations. They keep failing. What should I do?

First, can you provide the error message you're encountering? That will help in diagnosing the issue.

I'm getting a 'No such table' error when I try to migrate.

This usually means that the migration is trying to access a table that doesn't exist. Have you checked if the previous migrations were applied successfully?

I think I missed a migration step. How can I fix that?

You can try running flask db migrate to create a new migration file, then flask db upgrade to apply it. Make sure to check the migration history.

Thanks! That helps a lot. What if I want to revert a migration?

You can use flask db downgrade followed by the migration identifier to revert to a previous state.
