context in nested serializers django rest framework

Ok i found a working solution. I replaced the ChildSerializer assignment in the Parent class with a SerializerMethodField which adds the context. This is then passed to the get_fields method in my CustomModelSerializer: class ChildSerializer(CustomModelSerializer): class Meta: fields = (‘c_name’, ) model = Child class ParentSerializer(CustomModelSerializer): child = serializers.SerializerMethodField(‘get_child_serializer’) class Meta: model = Parent fields … Read more

Django Rest framework, how to include ‘__all__’ fields and a related field in ModelSerializer ?

Like @DanEEStart said, DjangoRestFramework don’t have a simple way to extend the ‘all‘ value for fields, because the get_field_names methods seems to be designed to work that way.

How can I test binary file uploading with django-rest-framework’s test client?

When testing file uploads, you should pass the stream object into the request, not the data.

How to pass extra context to Django Rest Framework serializers

You have to use get_object as func, not as property: class PostViewSets(viewsets.ModelViewSet): queryset = Post.objects.all() serializer_class = PostSerializer def get_serializer_context(self): context = super(PostViewSets, self).get_serializer_context() author = self.get_object().author author_posts = self.get_queryset().filter(author=author) context.update({‘author_posts’: author_posts}) return context

Django: app level variables

A possible solution is to implement a custom Django middleware, as described in https://docs.djangoproject.com/ja/1.9/topics/http/middleware/. You could initialize the HTTP connection pool in the middleware’s __init__ method, which is only called once at the first request. Then, start the HTTP request during process_request and on process_response check it has finished (or wait for it) and append … Read more

Override JSONSerializer on django rest framework

I think you have your answer there in the post you’ve given. You need to define custom JSON renderer from rest_framework.renderers import JSONRenderer class EmberJSONRenderer(JSONRenderer): def render(self, data, accepted_media_type=None, renderer_context=None): data = {‘element’: data} return super(EmberJSONRenderer, self).render(data, accepted_media_type, renderer_context) and use it as default renderer either in settings or as an explicitly defined render for … Read more
