12709	Refetch method for getting a fresh model instance	Jukka Välimaa	nobody	"It is often useful to get a fresh instance of a model object, with data from db. A typical case is testing some view code using the test client, when the
view is supposed to save some model changes into database. For example:

{{{
client.post('some_url', {'id': obj.id, 'description': 'new'})
fresh_obj = ObjClass.objects.get(pk=obj.pk)
self.assertEqual('new', fresh_obj.description)
}}}

This ticket proposes adding a method to Model that can be used to fetch a ""fresh"" version of a model object from the database. It is functionally the same as the use of objects.get in the example above, but more convenient and elegant.

{{{
fresh_obj = obj.refetch()
}}}
