IOS&Andorid API and Django Rest Framework

Overview

App API support for Django REST Framework

• Documentation: None
• Format specification: http://jsonapi.org/format/

1. By default, Django REST Framework will produce a request like:

   http://example.com/api/1.0/identities/?page=1
   

and then the response like:

{
    "count": 200,
    "msg": "success!",
    "data": {
        "list": [
            {
                "id": 3,
                "username": "john1",
                "full_name": "John Coltrane1"
            },
             {
                "id": 4,
                "username": "john2",
                "full_name": "John Coltrane2"
            },
        ],
        "total_count": 2,
        "total_pages": 1
    }
}

2. if you want get object info, you will produce a request like:

   http://example.com/api/1.0/identities/1/

and then the response like:

{
    "count": 200,
    "msg": "success!",
    "data": {
        "id": 1,
        "username": "john2",
        "full_name": "John Coltrane2"
    }
}

Goals

As a Django REST Framework APP API (short DJA) we are trying to address following goals:

1. Support the REST_FRAMEWORK_APPAPI to compliance
2. Be as compatible with Django REST Framework as possible
3. Have sane defaults to be as easy to pick up as possible
4. Be solid and tested with good coverage
5. Be performant

Requirements

1. Python (3.5, 3.6, 3.7)
2. Django (1.11, 2.1, 2.2)
3. Django REST Framework (3.10)

We highly recommend and only officially support the latest patch release of each Python, Django and REST Framework series.

Installation

From PyPI

$ pip install djangorestframework-appapi

From Source

$ git clone https://github.com/allran/djangorestframework-appapi.git
$ cd django-rest-framework-app-api
$ pip install -e .

Running the example app

It is recommended to create a virtualenv for testing. Assuming it is already installed and activated:

$ git clone https://github.com/allran/djangorestframework-appapi.git
$ cd django-rest-framework-app-api
$ pip install -U -e . -r requirements.txt
$ django-admin migrate --settings=example_project.settings
$ django-admin loaddata drf_example --settings=example_project.settings
$ django-admin runserver --settings=example_project.settings

Browse to http://localhost:8000

Running Tests and linting

It is recommended to create a virtualenv for testing. Assuming it is already installed and activated:

$ pip install -Ur requirements.txt
$ flake8
$ pytest

Usage

一. rest_framework_app_api assumes you are using class-based renderers in Django Rest Framework.

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework_app_api.renderers.JSONRenderer',
    ),
}

then you can get the app response data

{
    "data": [
        {
            "id": 1,
            "name": "张三"
        },
        {
            "id": 2,
            "name": "李四"
        }
    ],
    "code": 200,
    "msg": "OK"
}

二. rest_framework_app_api assumes you are using class-based views in Django Rest Framework.

if you use like ListAPIView in from rest_framework.generics import ListAPIView, please replace with from rest_framework_app_api.generics import ListAPIView.

from snippets.models import Snippet
from snippets.serializers import SnippetSerializer
from rest_framework_app_api import generics

class SnippetList(generics.ListCreateAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

class SnippetDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

1. if you use like ListModelMixin in from rest_framework.mixins import ListModelMixin, please replace with from rest_framework_app_api.mixins import ListModelMixin.

from snippets.models import Snippet
from snippets.serializers import SnippetSerializer
from rest_framework_app_api import mixins
from rest_framework import generics

class SnippetDetail(mixins.RetrieveModelMixin,
                    mixins.UpdateModelMixin,
                    mixins.DestroyModelMixin,
                    generics.GenericAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

    def get(self, request, *args, **kwargs):
        return self.retrieve(request, *args, **kwargs)

    def put(self, request, *args, **kwargs):
        return self.update(request, *args, **kwargs)

    def delete(self, request, *args, **kwargs):
        return self.destroy(request, *args, **kwargs)

2. if you use like APIView in from rest_framework.views import APIView, please replace with from rest_framework_app_api.views import APIView.

from snippets.models import Snippet
from snippets.serializers import SnippetSerializer
from rest_framework_app_api.views import APIView
from rest_framework_app_api.response import APIResponse
from rest_framework import status

class SnippetList(APIView):
    """
    List all snippets, or create a new snippet.
    """
    def get(self, request, format=None):
        snippets = Snippet.objects.all()
        serializer = SnippetSerializer(snippets, many=True)
        return APIResponse(serializer.data)

    def post(self, request, format=None):
        serializer = SnippetSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return APIResponse(serializer.data)
        return APIResponse(serializer.errors)

class SnippetDetail(APIView):
    """
    Retrieve, update or delete a snippet instance.
    """
    def get(self, request, pk, format=None):
        snippet = self.get_object(pk)
        serializer = SnippetSerializer(snippet)
        return APIResponse(serializer.data)

    def put(self, request, pk, format=None):
        snippet = self.get_object(pk)
        serializer = SnippetSerializer(snippet, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return APIResponse(serializer.data)
        return APIResponse(serializer.errors, code=status.HTTP_400_BAD_REQUEST)

    def delete(self, request, pk, format=None):
        snippet = self.get_object(pk)
        snippet.delete()
        return APIResponse(code=status.HTTP_204_NO_CONTENT)

3. if you use like ModelViewSet in from rest_framework.viewsets import ModelViewSet, please replace with from rest_framework_app_api.viewsets import ModelViewSet.

from snippets.models import Snippet
from rest_framework_app_api import viewsets

class SnippetViewSet(viewsets.ModelViewSet):
    queryset = Author.objects.all()
    serializer_class = AuthorSerializer

4. if you use like Response in from rest_framework.response import Response, please replace with from rest_framework_app_api.response import APIResponse.
