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.
