Provides a .update(request, *args, **kwargs) method, that implements updating and saving an existing model instance. For example Content-Disposition: attachment; filename=upload.jpg.

The name of a query parameter, which can be used to specify the ordering of results returned by OrderingFilter. By default, there are no permissions or throttling applied to the obtain_auth_token view. A list or tuple of authentication classes, that determines the default set of authenticators used when accessing the request.user or request.auth properties. serializers, JSONXMLPython, REST frameworkserializersDjangoFormModelFormSerializerModelSerializer, Comment, CommentSerializercommentcommentSerializerForm, Pythonjson, .create()update(), DjangoCommentDjango, .save(), .save(), .create().update(), , .create().update()validated_data, .create().update()contact form, serializer.validated_data, is_valid().errors, non_field_errorsnon_field_errorsREST frameworkNON_FIELD_ERRORS_KEY For example, you can use it to provide API responses like {"errors": [{"message": "Failure", "code": ""} ]}.

When returning decimal objects in API representations that do not support a native decimal type, it is normally best to return the value as a string. When request.data is accessed, REST framework will examine the Content-Type header on the incoming request, and determine which parser to use to parse the request content. It generates tokens in a JWTed way with an easy setup. settings.py Settings.

Defaults to returning the serializer_class attribute. A list of format strings that should be used by default for parsing inputs to DateField serializer fields. Okay, we're done. This allows throttling to more accurately identify client IP addresses. Returns the queryset that should be used for list views, and that should be used as the base for lookups in detail views.
