created_at

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

get_next_by_created_at(*, field=<django.db.models.fields.DateTimeField: created_at>, is_next=True, **kwargs)

get_previous_by_created_at(*, field=<django.db.models.fields.DateTimeField: created_at>, is_next=False, **kwargs)

hook(_task)

id

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

objects = <django.db.models.manager.Manager object>

owner

Accessor to the related object on the forward side of a many-to-one or one-to-one (via ForwardOneToOneDescriptor subclass) relation.

In the example:

class Child(Model):
    parent = ForeignKey(Parent, related_name='children')

Child.parent is a ForwardManyToOneDescriptor instance.

owner_id

parameters

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

classmethod register_task_class(task_class)

run(*_args, **_kwargs)

save(*args, **kwargs)

Save the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.

schedule()

status

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

task

Accessor to the related object on the forward side of a one-to-one relation.

In the example:

class Restaurant(Model):
    place = OneToOneField(Place, related_name='restaurant')

Restaurant.place is a ForwardOneToOneDescriptor instance.

task_class

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.
