-1 publish = serializers.HyperlinkedIdentityField(view_name='ttt',lookup_field='publish_id',lookup_url_kwarg='pky')

# class BookSerializer(serializers.Serializer):

# name = serializers.CharField()

# # publish = serializers.CharField()

# publish = serializers.HyperlinkedIdentityField(view_name='ttt',lookup_field='publish_id',lookup_url_kwarg='pky')

from rest_framework.exceptions import ValidationError

-2 view_name:路由的別名,lookup_field:根據表的哪個字段,來拼路徑,lookup_url_kwarg:反向解析有名分組的名字

-3 寫路由:url(r'^publish/(?P<pky>\d+)', views.Publish.as_view(),name='ttt'),

-4 實例化序列化類的時候,需要把request對象傳過去

book_ser=BookSerializer(ret,many=True,context={'request': request})

class Books(APIView):

def get(self, request, *args, **kwargs):

ret = models.Book.objects.all()

# 生成一個序列化的對象,傳參數

# 序列化多條,記住many=True

book_ser = BookSerializer(ret, many=True, context={'request': request})

print(book_ser.data)

return JsonResponse(book_ser.data, safe=False)

向AI問一下細節
