What does the doctrine do: generate-migrations-diff does diff against?

Question

This function is designed to create doctrine migration classes based on the difference between old and new schemes.

Okay, where is the old circuit with which the system differs? I am in a symfony project and in my configurations there is only one schema.yml.

The main problem of my problem was that there was a problem with my schema that caused the migration to fail (I had a column named "group") ... after making a name change to my schema ... ensuring the generation is migrated and the migration attempts will be always give errors, as previous attempts at migration are only partially completed.

So, I wanted to return everything to the "pristine" state, as if there had never been a migration, I want the current schema / database to be made as if it were version 0, and a new migration class.

However, manually reloading my db and deleting the migration classes do not work, and the created diff classes insist on dropping tables that no longer exist.

So, I guess there is a cached file somewhere with old schema data that it compares with?

Thanks for any help.

It is no different from cached schema.yml, comparing it with your model classes.
