django.db.models.fields.related_descriptors.ForwardManyToOneDescriptor

class documentation

class ForwardManyToOneDescriptor:

Known subclasses: django.db.models.fields.related_descriptors.ForwardOneToOneDescriptor

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.

Method	`__get__`	Get the related instance through the forward relation.
Method	`__init__`	Undocumented
Method	`__reduce__`	Pickling should return the instance attached by self.field on the model, not a new copy of that descriptor. Use getattr() to retrieve the instance directly from the model.
Method	`__set__`	Set the related instance through the forward relation.
Method	`get_object`	Undocumented
Method	`get_prefetch_queryset`	Undocumented
Method	`get_queryset`	Undocumented
Method	`is_cached`	Undocumented
Instance Variable	`field`	Undocumented
Property	`RelatedObjectDoesNotExist`	Undocumented

def __get__(self, instance, cls=None):

Get the related instance through the forward relation.

With the example above, when getting child.parent:

self is the descriptor managing the parent attribute
instance is the child instance
cls is the Child class (we don't need it)

def __init__(self, field_with_rel):

Undocumented

def __reduce__(self):

Pickling should return the instance attached by self.field on the model, not a new copy of that descriptor. Use getattr() to retrieve the instance directly from the model.

def __set__(self, instance, value):

overridden in django.db.models.fields.related_descriptors.ForwardOneToOneDescriptor

Set the related instance through the forward relation.

With the example above, when setting child.parent = parent:

self is the descriptor managing the parent attribute
instance is the child instance
value is the parent instance on the right of the equal sign
