what is self.nested

Is it possible to limit fields when declared so that a model serializer can be re-used, e.g:

UserModelSerializer(fields=('id', 'first_name', 'last_name',))

This way I can re-use the UserModelSerializer in other places without exposing additional info such as username, email etc when nesting it.

Hello,

I am using Django rest framework 3.6.4 and I am getting the following error:

File "/home/vagrant/.virtualenvs/api/lib/python3.6/site-packages/rest_framework_dyn_serializer.py", line 44, in init
field_name.context = self.context
AttributeError: can't set attribute

I think that the error is related to the following change in the version 3.6.4:

encode/django-rest-framework@563020e

You can see in the line 599 that @cached_property is not longer used, and it was replaced for @Property, I think that the (for in ) in line https://github.com/Nepherhotep/django-rest-framework-dyn-serializer/blob/master/rest_framework_dyn_serializer.py#L43 is not need anymore, but I am not totally sure.

Regards.

Here is an example taken from test with a little change

# Pass limit_fields = False to nested serializer
class ArticleDynSerializer(DynModelSerializer):
    author = AuthorDynSerializer(required=False, limit_fields=False)

    class Meta:
        model = Article
        fields_param = 'article_fields'
        fields = ['id', 'title', 'created', 'updated', 'content', 'author']

class ArticleViewSet(viewsets.ReadOnlyModelViewSet):
    queryset = Article.objects.all().order_by('id')

    def get_serializer(self, *args, **kwargs):
        context = self.get_serializer_context()
        context['request'] = self.request
        s = ArticleDynSerializer(*args, context=context, limit_fields=True, **kwargs)
        return s

In such case author serializer behaves like dynamic in spite of limit_fields is set to False. So all fields for nested serializers always must be defined explicitly in the request.
