db.migrations.operations.SeparateDatabaseAndState

class SeparateDatabaseAndState(database_operations=None, state_operations=None) [source]

A highly specialized operation that let you mix and match the database (schema-changing) and state (autodetector-powering) aspects of operations.

It accepts two list of operations, and when asked to apply state will use the state list, and when asked to apply changes to the database will use the database list. Do not use this operation unless you’re very sure you know what you’re doing.
