Dynamically include or exclude Serializer class fields

Question

In my User profile model I\'ve included a show_email field explicitly. So, to add this feature to my API, the UserSerializer class looks like this:

This answer comes late but for future google searches: there is an example in the documentation about Dynamically modifying fields. So, by passing an argument to the serializer, you control whether or not a field is processed:

serializer = MyPostSerializer(posts, show_email=permissions)

and then in the init function in the serializer you can do something like:

class MyPostSerializer(serializers.ModelSerializer):

def __init__(self, *args, **kwargs):
    show_email = kwargs.pop('show_email', None)

    # Instantiate the superclass normally
    super(DeviceSerializer, self).__init__(*args, **kwargs)

    if not show_email:
        self.fields.pop("show_email")

Now the show_email field will be ignored by the serializer.
