end_date

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_end_date(*, field=<django.db.models.fields.DateField: end_date>, is_next=True, **kwargs)

get_next_by_start_date(*, field=<django.db.models.fields.DateField: start_date>, is_next=True, **kwargs)

get_previous_by_end_date(*, field=<django.db.models.fields.DateField: end_date>, is_next=False, **kwargs)

get_previous_by_start_date(*, field=<django.db.models.fields.DateField: start_date>, is_next=False, **kwargs)

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>

start_date

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

type

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.

In the example:

class Child(Model):

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.
