Django REST framework

• The source repository is https://github.com/ccapeng/bookstore_api

• Installation pip install djangorestframework

• In the regular django, you need to implement view in order to output data. with REST framework, only need to implement serializer book.serializers.py in order to save data. And, register url in

  book.urls.py When server startup, then you can view api in http://127.0.0.1:8000/api/category/ http://127.0.0.1:8000/api/publisher/ http://127.0.0.1:8000/api/author/ http://127.0.0.1:8000/api/book/

• Snake-case to camel-case Python is a language like all against c syntax, no curly brace block match and use snake-case for the variables. In general, we also use camel-case in javascript, json. The following implementation totally take the extra translation.

  Add

    utils.api.parsers.py
    utils.api.renders.py

  This parser was copied from https://gist.github.com/vbabiy/5842073.

  So in the settings.py, also update:

    REST_FRAMEWORK = {
        'DEFAULT_RENDERER_CLASSES': (
            'utils.api.renderers.CamelCaseJSONRenderer',
            'rest_framework.renderers.BrowsableAPIRenderer',
        ),
  
        'DEFAULT_PARSER_CLASSES': (
            'utils.api.parsers.CamelCaseJSONRenderer',
            'rest_framework.parsers.FormParser',
            'rest_framework.parsers.MultiPartParser'
        ),
    }

• To bypass cross Origin, you need to add the following middleware implementation into order to have browser accept the cross site permission. Middleware implement at bookstore_api.corsapp.middleware.py

    class CorsMiddleware(object):
  
        def __init__(self, get_response):
            self.get_response = get_response
  
        def __call__(self, request):
            response = self.get_response(request)
            response["Access-Control-Allow-Origin"] = "*"
            response["Access-Control-Allow-Headers"] = "*"
            response["Access-Control-Allow-Methods"] = "*"
  
            return response
