Squashmigrations --hard

[Pascal Briet]

Here is a suggestion : instead of trying to merge together migrations, start from the models.
It would be a sort of equivalent of applying ./manage.py makemigrations on a project with no migrations.

I reproduced this in a script, and it's working like a charm :

• List all the migrations for every app
• Remove the migration files
• Run makemigrations
• Put a "replaces = []" statement in each one
• Rename them to avoid conflicts.

See script attached. It is surely not the way you would implement it directly in Django, but it might help.

The idea behind it is : not struggling anymore with squashmigrations. Get something clean, and forget about the past.
