Drf之modelViewSet序列化接口（七）

objson.py

from rest_framework import serializers
from app import models
class BookJson(serializers.ModelSerializer):
    class Meta:
        model = models.Book
        fields = '__all__'

views.py

from rest_framework.viewsets import ModelViewSet
from rest_framework.response import Response
from app import models.objson


class BookView(ModelViewSet):
	queryset = models.Book.objects.all()  #取数据库数据,这里all应该是要加的，如果错了的话再回来改
	serializer_class = objson.BookJson  #序列化组件
	lookup_field = 'pk'  #有名分组的Key

#这个是自定义的方法，可以在urls.py中捕获id这个值，可传可不传，如果不传，urls.py中不需要使用有名分组。
def get_book_by_id(self,request,id,*args,**kwargs)
	book = models.Book.objects.filter(pk=id).first()
	book_data = objson.BookJson(book).data
	return Response(
	{'status':0,
	'msg':'ok',
	'result':book_data
	}
	)

urls.py

from app import views
urlpatterns = [
#基础方法：不传参，获取全部数据或创建数据
url(r'^books/',views.BookView.as_view({'get':'list','post','create'})),
#基础方法：传参，获取单条数据，更新单条数据，删除单条数据。
url(r'^book/(?P\d+)/',views.BookView.as_view({'get':'retrieve','put':'update','delete':'destroy'})),
#自定义方法
url(r'book/(?P\d+)/',views.Bookview.as_view({'get':'get_book_by_id'}))
