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_sources_plex', '0004_groupplexsourceconnection_plexsourcepropertymapping_and_more'), ('authentik_core', '0044_usersourceconnection_new_identifier')]
operations = [<RunPython code=<function migrate_identifier>, reverse_code=<function RunPython.noop>>, <RemoveField model_name='userplexsourceconnection', name='identifier'>]
