Keep your custom Migrations in your project

A proof of concept.

If you cant't/won't use the apps Migration files this workaround can be helpful for you.

We assume you have a clean Database without any Migrations applied and a Project named my_project that you are working on. Add the below snippet in your settings.py right after INSTALLED_APPS.

This tells django to use migration files from the module in my_project.migrations.<appname>.migrations.
