How can i access QueryString values in Serializer Django Rest Framework

According to the docs you want to use self.request.QUERY_PARAMS

You can see it being used here

UPDATE:

As of DRF 3.0:

The usage of request.QUERY_PARAMS is now pending deprecation in favor of the lowercased request.query_params

When using ViewSets, you can access the request in the serializer context (like you access the view). You can access the query params from this

def get_alternate_name(self, obj):
    request = self.context['request']
    print request.query_params['q']
    return 'foo'

The attribute view.kwargs contains the named arguments parsed from your url-config, so from the path-part.
