Installation

1. Install the package using pip:

pip install drf-standardized-response

2. Add drf_standardized_response to INSTALLED_APPS

INSTALLED_APPS = [
    ...,
    "drf_standardized_response",
]

3. Add renderer for all API views

"DEFAULT_RENDERER_CLASSES": [
    ...,
    "drf_standardized_response.renderers.StandardizedJSONRenderer",
    ...,
]

Now, your API responses will be standardized.

How It Works

The package takes care of standardization all responses returned by views.

• if you return a string response, it will be wrapped in a message key. For example:

class MyView(APIView):
    def get(self, request):
        return Response("Thanks for using DRF Standardized Response")

The response will be:

{
    "success": true,
    "message": "Thanks for using DRF Standardized Response"
}

• If your response data contains message, it will override the standardized message.

class MyView(APIView):
    def get(self, request):
        return Response({"message": "Thanks for using DRF Standardized Response"})

The response will be:

{
    "success": true,
    "message": "Thanks for using DRF Standardized Response"
}

• if you return a dict response, it will be wrapped in a data key. For demostration, we will return a user profile.

class MyView(APIView):
    def get(self, request):
        user = request.user
        data = UserProfileSerializer(user).data
        return Response(data)

The response will be:

{
    "success": true,
    "message": "OK",
    "data": { # user profile },
}

• if you return a list or tuple response, it will be wrapped in a data key. For demostration, we will return a list of user profiles.

class MyView(APIView):
    def get(self, request):
        users = User.objects.all()
        data = UserProfileSerializer(users, many=True).data
        return Response(data)

The response will be:

{
    "success": true,
    "message": "OK",
    "data": [ # list of user profiles ],
}

Customizing

Custom Wrapper Key

You can customize the key used to wrap the response data. By default, the key is data. To change it, set the DEFAULT_WRAPPER_KEY in pkg settings.

DRF_STANDARDIZED_RESPONSE = {
    "DEFAULT_WRAPPER_KEY": "results",
}

Or you can change it per view basis using the wrapper_key argument in the view:

class MyView(APIView):
    wrapper_key = "results"

Excluded Fields From Wrapping

You can exclude fields from wrapping. By default, the fields are links. To customize it, Set the DEFFAULT_WRAPPING_EXCLUDED_FIELDS in pkg settings.

DRF_STANDARDIZED_RESPONSE = {
    "DEFFAULT_WRAPPING_EXCLUDED_FIELDS": ["links", "meta"],
}

Or you can change it per view basis using the wrapping_excluded_fields argument in the view:

class MyView(APIView):
    wrapping_excluded_fields = ["links", "meta"]

Wrapping Paginated Response

By default, paginated responses are not wrapped. To customize this behavior, Set the WRAP_PAGINATED_RESPONSE in pkg settings.

DRF_STANDARDIZED_RESPONSE = {
    "WRAP_PAGINATED_RESPONSE": True,
}

Disable Standardization On View

You can disable standardization on a view by setting the should_strandardize property to False.

class MyView(APIView):
    should_strandardize = False

Custom Response Standarizer

You can also provide your own response standarizer to format response to your desired format. By default, the standarizer is drf_standardized_response.response_standarizer.ResponseStandardizer, which is well suitable for most projects.

But if you need that, set the RESPONSE_STANDARDIZER_CLASS in pkg settings.

DRF_STANDARDIZED_RESPONSE = {
    "RESPONSE_STANDARDIZER_CLASS": "your_app.response_standarizer.CustomResponseStandardizer",
}

DRF-Spectacular Integration

If you plan to use drf-spectacular to generate an OpenAPI 3 schema,

install with pip:

pip install drf-standardized-response[openapi].

After that, Set the default schema class to the one provided by the package

REST_FRAMEWORK = {
    # other settings
    "DEFAULT_SCHEMA_CLASS": "drf_standardized_response.openapi.AutoSchema"
}

Alternatively, you can use the drf_standardized_response.openapi.StandardizedAutoSchemaMixin mixin to your own schema class. (useful when using drf-standardized-errors).

Now, the OpenAPI schema will be generated with the standardized response format.

Disable Schema Standardization On Serializer

You can disable openapi schema standardization on a serializer by setting the should_standardize_schema property to False on Meta.

class MySerializer(serializers.Serializer):
    class Meta:
        should_standardize_schema = False
