django.db.migrations.operations.AlterModelOptions

class documentation

class AlterModelOptions(ModelOptionOperation):

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
Class Variable	`reduces_to_sql`	Undocumented
Class Variable	`reversible`	Undocumented
Class Variable	`serialization_expand_args`	Undocumented
Instance Variable	`_constructor_args`	Undocumented
