+Fields
+======
+
+Graphene-Django provides some useful fields to help integrate Django with your GraphQL
+Schema.
+
+DjangoListField
+---------------
+
+``DjangoListField`` allows you to define a list of :ref:`DjangoObjectType<queries-objecttypes>`'s. By default it will resolve the default queryset of the Django model.
+
+.. code:: python
+
+   from graphene import ObjectType, Schema
+   from graphene_django import DjangoListField
+
+   class RecipeType(DjangoObjectType):
+      class Meta:
+         model = Recipe
+         fields = ("title", "instructions")
+
+   class Query(ObjectType):
+      recipes = DjangoListField(RecipeType)
+
+   schema = Schema(query=Query)
+
+The above code results in the following schema definition:
+
+.. code::
+
+   schema {
+     query: Query
+   }
+
+   type Query {
+     recipes: [RecipeType!]
+   }
+
+   type RecipeType {
+     title: String!
+     instructions: String!
+   }
+
+Custom resolvers
+****************
+
+If your ``DjangoObjectType`` has defined a custom
+:ref:`get_queryset<django-objecttype-get-queryset>` method, when resolving a
+``DjangoListField`` it will be called with either the return of the field
+resolver (if one is defined) or the default queryset from the Django model.
+
+For example the following schema will only resolve recipes which have been
+published and have a title:
+
+.. code:: python
+
+   from graphene import ObjectType, Schema
+   from graphene_django import DjangoListField
+
+   class RecipeType(DjangoObjectType):
+      class Meta:
+         model = Recipe
+         fields = ("title", "instructions")
+
+      @classmethod
+      def get_queryset(cls, queryset, info):
+         # Filter out recipes that have no title
+         return queryset.exclude(title__exact="")
+
+   class Query(ObjectType):
+      recipes = DjangoListField(RecipeType)
+
+      def resolve_recipes(parent, info):
+         # Only get recipes that have been published
+         return Recipe.objects.filter(published=True)

+Subscriptions
+=============
+
+The ``graphene-django`` project does not currently support GraphQL subscriptions out of the box. However, there are
+several community-driven modules for adding subscription support, and the provided GraphiQL interface supports
+running subscription operations over a websocket.
+
+To implement websocket-based support for GraphQL subscriptions, you’ll need to do the following:
+
+1. Install and configure `django-channels <https://channels.readthedocs.io/en/latest/installation.html>`_.
+2. Install and configure* a third-party module for adding subscription support over websockets. A few options include:
+
+   -  `graphql-python/graphql-ws <https://github.com/graphql-python/graphql-ws>`_
+   -  `datavance/django-channels-graphql-ws <https://github.com/datadvance/DjangoChannelsGraphqlWs>`_
+   -  `jaydenwindle/graphene-subscriptions <https://github.com/jaydenwindle/graphene-subscriptions>`_
+
+3. Ensure that your application (or at least your GraphQL endpoint) is being served via an ASGI protocol server like
+   daphne (built in to ``django-channels``), `uvicorn <https://www.uvicorn.org/>`_, or
+   `hypercorn <https://pgjones.gitlab.io/hypercorn/>`_.
+
+..
+
+   *** Note:** By default, the GraphiQL interface that comes with
+   ``graphene-django`` assumes that you are handling subscriptions at
+   the same path as any other operation (i.e., you configured both
+   ``urls.py`` and ``routing.py`` to handle GraphQL operations at the
+   same path, like ``/graphql``).
+
+   If these URLs differ, GraphiQL will try to run your subscription over
+   HTTP, which will produce an error. If you need to use a different URL
+   for handling websocket connections, you can configure
+   ``SUBSCRIPTION_PATH`` in your ``settings.py``:
+
+   .. code:: python
+
+      GRAPHENE = {
+          # ...
+          "SUBSCRIPTION_PATH": "/ws/graphql"  # The path you configured in `routing.py`, including a leading slash.
+      }
+
+Once your application is properly configured to handle subscriptions, you can use the GraphiQL interface to test
+subscriptions like any other operation.

-----------------------

-So far, we have been able to fetch list of objects and follow relation. But what about single objects?
