The value returned by this callable will then be passed into to the field's constructor as usual.
 
-Before we see a code example, there's one further things to note: instead of passing arbitrary arguments (like `team` in the example above) into the form's constructor in the view, we borrow a useful idiom from Django REST framework serializers and instead pass a _single_ argument called `context`, which is a dictionary that can contain any values you need from the view.
