class AlterModelOptions(ModelOptionOperation):

View In Hierarchy

Set new model options that don't directly affect the database schema (like verbose_name, permissions, ordering). Python code in migrations may still need them.
Constant ALTER​_OPTION​_KEYS Undocumented
Method __init__ Undocumented
Method database​_backwards Perform the mutation on the database schema in the reverse direction - e.g. if this were CreateModel, it would in fact drop the model's table.
Method database​_forwards Perform the mutation on the database schema in the normal (forwards) direction.
Method deconstruct Return a 3-tuple of class import path (or just name if it lives under django.db.migrations), positional arguments, and keyword arguments.
Method describe Output a brief summary of what the action does.
Method state​_forwards Take the state from the previous migration, and mutate it so that it matches what this migration would perform.
Instance Variable options Undocumented
Property migration​_name​_fragment A filename part suitable for automatically naming a migration containing this operation, or None if not applicable.

Inherited from ModelOptionOperation:

Method reduce Return either a list of operations the actual operation should be replaced with or a boolean that indicates whether or not the specified operation can be optimized across.

Inherited from ModelOperation (via ModelOptionOperation):

Method references​_model Return True if there is a chance this operation references the given model name (as a string), with an app label for accuracy.
Instance Variable name Undocumented
Property name​_lower Undocumented

Inherited from Operation (via ModelOptionOperation, ModelOperation):

Method __new__ Undocumented
Method __repr__ Undocumented
Method allow​_migrate​_model Return whether or not a model may be migrated.
Method references​_field Return True if there is a chance this operation references the given field name, with an app label for accuracy.
Class Variable atomic Undocumented
Class Variable elidable Undocumented
