The ``save()`` method has no return value.

--------------------------------------------

Updating ``ForeignKey`` fields works exactly the same way as saving a normal
|
||||
field; simply assign an object of the right type to the field in question::
|
||||
|
||||
cheese_blog = Blog.objects.get(name="Cheddar Talk")
|
||||
entry.blog = cheese_blog
|
||||
entry.save()
|
||||
|
||||
Updating a ``ManyToManyField`` works a little differently; use the ``add()``
|
||||
method on the field to add a record to the relation::
|
||||
|
||||
joe = Author.objects.create(name="Joe")
|
||||
entry.author = joe
|
||||
entry.save()
|
||||
entry.authors.add(joe)

Django will complain if you try to assign an object of the wrong type.
