The base class for all migrations.

Migration files will import this from django.db.migrations.Migration and subclass it as a class called Migration. It will have one or more of the following attributes:

  • operations: A list of Operation instances, probably from django.db.migrations.operations
  • dependencies: A list of tuples of (app_path, migration_name)
  • run_before: A list of tuples of (app_path, migration_name)
  • replaces: A list of migration_names

Note that all migrations come out of migrations and into the Loader or Graph as instances, having been initialized with their app label and name.

dependencies = [('authentik_brands', '0007_brand_default_application')]
operations = [<AddField model_name='brand', name='branding_custom_css', field=<django.db.models.fields.TextField>>, <RunPython <function migrate_custom_css>>]
