class Meta:
model = User

class PostSerializer(serializers.ModelSerializer):
author = UserSerializer(required=False, read_only=True)
photos = serializers.HyperlinkedIdentityField('photos', read_only=True)
# author = serializers.HyperlinkedRelatedField(view_name='user-detail', lookup_field='username')
def get_validation_exclusions(self, *args, **kwargs):
# Need to exclude `user` since we'll add that later based off the request
exclusions = super(PostSerializer, self).get_validation_exclusions(*args, **kwargs)
return exclusions + ['author']
class Meta:
model = Post
class PhotoSerializer(serializers.ModelSerializer):
image = serializers.Field('image.url' , read_only=True)
