A Django admin command to recreate all migrations in a project. Like a squashmigrations command on steroids.

The problem

The built-in squashmigrations command is great, but it has some limitations:

• It only works on a single app at a time, which means that you need to run it for each app in your project. On a project with enough cross-apps dependencies, it quickly becomes impossible to run.
• It doesn't optimise the operations, it only reduces the number of migration files. That being said, Django 4.1 introduced a new optimizemigrations command which sounds like it might be doing just this.

This command aims at solving this problem, by recreating all the migration files in the whole project, from scratch, and mark them as applied by using the replaces attribute.

It makes an important trade-off though: it does NOT try to be correct when setting the replaces attribute. The only guarantees are that:

• all old migrations are marked as replaced once.
• all new migrations replace at least one of the old migrations

This is OK to make this trade-off as long as all your environments are fully migrated when you deploy the remade migrations.
