Attributes Documentation

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

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

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

in_archive

Accessor to the related objects manager on the forward and reverse sides of a many-to-many relation.

In the example:

class Pizza(Model):
    toppings = ManyToManyField(Topping, related_name='pizzas')

Pizza.toppings and Topping.pizzas are ManyToManyDescriptor instances.

Most of the implementation is delegated to a dynamically defined manager class built by create_forward_many_to_many_manager() defined below.

institution_publisher

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.

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

person_publisher

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.

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

sources

Accessor to the related objects manager on the reverse side of a many-to-one relation.

In the example:

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

Parent.children is a ReverseManyToOneDescriptor instance.

Most of the implementation is delegated to a dynamically defined manager class built by create_forward_many_to_many_manager() defined below.

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

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