New description:
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.
