+Related objects reference
+=========================
+
+.. currentmodule:: django.db.models.fields.related
+
+.. class:: RelatedManager
+
+ A "related manager" is a manager used in a one-to-many or many-to-many
+ related context. This happens in two cases:
+
+ * The "other side" of a :class:`~django.db.models.ForeignKey` relation.
+ That is::
+
+ class Reporter(models.Model):
+ ...
+
+ class Article(models.Model):
+ reporter = models.ForeignKey(Reporter)
+
+ In the above example, the methods below will be available on
+ the manager ``reporter.article_set``.
+
+ * Both sides of a :class:`~django.db.models.ManyToManyField` relation::
+
+ class Topping(models.Model):
+ ...
+
+ class Pizza(models.Model):
+ toppings = models.ManyToManyField(Topping)
+
+ In this example, the methods below will be available both on
+ ``topping.pizza_set`` and on ``pizza.toppings``.
+
+ These related managers have some extra methods:
+
+ .. method:: add(obj1, [obj2, ...])
+
+ Adds the specified model objects to the related object set.
+
+ Example::
+
+ >>> b = Blog.objects.get(id=1)
+ >>> e = Entry.objects.get(id=234)
+ >>> b.entry_set.add(e) # Associates Entry e with Blog b.
+
+ .. method:: create(**kwargs)
+
+ Creates a new object, saves it and puts it in the related object set.
+ Returns the newly created object::
+
+ >>> b = Blog.objects.get(id=1)
+ >>> e = b.entry_set.create(
+ ... headline='Hello',
+ ... body_text='Hi',
+ ... pub_date=datetime.date(2005, 1, 1)
+ ... )
+
+ # No need to call e.save() at this point -- it's already been saved.
+
+ This is equivalent to (but much simpler than)::
+
+ >>> b = Blog.objects.get(id=1)
+ >>> e = Entry(
+ ... blog=b,
+ ... headline='Hello',
+ ... body_text='Hi',
+ ... pub_date=datetime.date(2005, 1, 1)
+ ... )
+ >>> e.save(force_insert=True)
+
+ Note that there's no need to specify the keyword argument of the model
+ that defines the relationship. In the above example, we don't pass the
+ parameter ``blog`` to ``create()``. Django figures out that the new
+ ``Entry`` object's ``blog`` field should be set to ``b``.
+
+ .. method:: remove(obj1, [obj2, ...])
+
+ Removes the specified model objects from the related object set::
+
+ >>> b = Blog.objects.get(id=1)
+ >>> e = Entry.objects.get(id=234)
+ >>> b.entry_set.remove(e) # Disassociates Entry e from Blog b.
+
+ In order to prevent database inconsistency, this method only exists on
+ :class:`~django.db.models.ForeignKey` objects where ``null=True``. If
+ the related field can't be set to ``None`` (``NULL``), then an object
+ can't be removed from a relation without being added to another. In the
+ above example, removing ``e`` from ``b.entry_set()`` is equivalent to
+ doing ``e.blog = None``, and because the ``blog``
+ :class:`~django.db.models.ForeignKey` doesn't have ``null=True``, this
+ is invalid.
+
+ .. method:: clear()
+
+ Removes all objects from the related object set::
+
+ >>> b = Blog.objects.get(id=1)
+ >>> b.entry_set.clear()
+
+ Note this doesn't delete the related objects -- it just disassociates
+ them.
+
+ Just like ``remove()``, ``clear()`` is only available on
+ :class:`~django.db.models.ForeignKey`\s where ``null=True``.
