Nested serializers only work with Django Model objects #249
Description
While DRF works perfectly fine with simple non-model instances, DJA crashes and can't be made to work correctly.
For example, this code works fine with DRF:
import random
from rest_framework.response import Response
from rest_framework.views import APIView
from rest_framework_json_api import serializers
from rest_framework_json_api.renderers import JSONRenderer as jsonapi_renderer
class Post(object):
def __init__(self, message):
super(Post, self).__init__()
self.pk = 'tmp-%s' % random.randint(1, 2**20) # Added to support json API referencing
self.message = message
class User(object):
def __init__(self, name, posts):
super(User, self).__init__()
self.pk = 'tmp-%s' % random.randint(1, 2**20) # Added to support json API referencing
self.name = name
self.posts = posts
class PostSerializer(serializers.Serializer):
message = serializers.CharField(max_length=200)
class UserSerializer(serializers.Serializer):
name = serializers.CharField(max_length=200)
posts = PostSerializer(many=True, read_only=True)
class UserView(APIView):
resource_name = 'users'
renderer_classes = (jsonapi_renderer,) # ! Uncommenting this causes failure !
def get(self, request, format=None):
p1 = Post("First message")
p2 = Post("Second message")
user = User('Bob', [p1, p2])
s = UserSerializer(user)
return Response(s.data)However, after uncommenting the line that specifies the JSON API renderer class to be used, the view crashes with:
'NoneType' object has no attribute 'Meta'
If DJA does not support Model-less references, it could at least be clearly stated in the documentation, mentioning also some workarounds if such exist. Though, I have not found any way to make this working yet.
