The field task_type is in the Task model, but it will be represented in your API as a job_type. Job_type = serializers.CharField(source='task_type') Take a look at this example: from rest_framework import serializersĬlass TaskSerializer(serializers.ModelSerializer): Using the serializer field source parameter will let you handle this easily. Very often, your model field names will differ from the required representation. Just make sure you‘re not overburdening your method fields with any heavy-lifting operations. SerializerMethodField accepts method_name, but it’s usually more convenient to use the default pattern for naming those methods, which is get_. Let’s say you have a model that stores datetime in a models.DateTimeField, but you want to use timestamp from epoch in your serialized representation: from rest_framework import serializersĬlass TagSerializer(serializers.ModelSerializer):Ĭreated = serializers.SerializerMethodField() SerializerMethodField is a read only field that computes its value at request processing time, by calling a method on the serializer class it is attached to.

Serializer.save() invokes an appropriate internal method based on arguments passed at initialization. Serializer.is_valid(raise_exception=True)Īnd finally, when updating an instance, you need to provide instance as well as data: def update(self, request, *args, **kwargs): Serializer = ProfileSerializer(data=request.data) Serializer = ProfileSerializer(instance=instance)īut in your create view you will define it in a different way: def create(self, request, *args, **kwargs): If in your view you want to serialize data that will be transmitted outside of your API, this is how you do it: def retrieve(self, request, *args, **kwargs):

In these terms we can distinguish 3 types of serializers: create, update and retrieve. The way it is initialized determines the action that it will fulfill. There is a handful of functionalities connected with serializers that you might want to know.Įvery serializer can be used for both reading and writing operations. Understanding different types of serializersĪs a DRF user you don’t need to bother with views and url configurations, so you will probably pay most of your attention to serializers, which act as translators between Django model instances and their representations such as json. Now that writing views is finished, you’ve saved enough time to have a cup of coffee.Ģ. You can even add some custom action to your viewset decorator. retrieve one of the tags by GET v1/tag/.list all your tags by sending GET request to v1/tag/,.Now your viewset is functional enough that you can: Url(r'^v1/', include(api_router.urls, namespace='v1')) from import url, includeįrom rest_framework.routers import DefaultRouterĪpi_router.register(r'tag', TagViewSet, 'tag')

This enforces best practices in naming your ulrs, making your API urls easily predictable. In addition, when using viewsets you typically want to use routers for url configuration. You can define your own mixins or use ModelViewSet, which provides the following actions: .list(), .retrieve(), .create(), .update(), .partial_update(), and .destroy() . Viewset mixins can be combined as needed. Permission_classes = (permissions.IsAuthenticated,) The following endpoints are fully provided by mixins: Here’s how you can define a viewset for that: class TagViewSet( Let’s imagine there is a Tag model in your project and you need to prepare a functionality that will let your users: list all the tags, create a new tag and retrieve its details. Every time you write views that should do more than one thing, a viewset is the thing that you want to go for.

The great thing about viewsets is how they make your code consistent and save you from repetition.

While regular views act as handlers for HTTP methods, viewsets give you actions, like create or list. Viewsets can be considered as extremely useful templates for your API views that provide typical interactions with your Django models. right now it returns the fields in a single object that is not nested.Let’s start with a simple (thus one of my favorites) DRF functionality.

I want to customize the django rest framework serializer return object to a specific requirement.
