from rest_framework.generics import GenericAPIView
二、GenericAPIView
from rest_framework.response import Response
from rest_framework import status
from rest_framework.generics import GenericAPIView
from .models import Projects
from .serializers import ProjectsModelSerializer
class ProjectsPage(GenericAPIView):
‘‘‘
类视图
‘‘‘
queryset = Projects.objects.all()
serializer_class = ProjectsModelSerializer
def get(self, request):
qs = self.get_queryset()
serializer_obj = self.get_serializer(instance=qs, many=True)
return Response({‘code‘: 0, ‘res‘: "success", ‘msg‘: serializer_obj.data}, status=status.HTTP_200_OK)
三、过滤
1.安装django-filter第三方库
pip install -i https://pypi.douban.com/simple django-filter
2.配置django-filter
INSTALLED_APPS = [
‘django_filters‘
]
3.引入方式
from django_filters.rest_framework import DjangoFilterBackend
4.使用方法
a.在视图中指定过滤引擎，也可以在全局指定
1）视图中指定，如果要指定多个引擎，直接继续添加到该列表中
filter_backends = [DjangoFilterBackend]
2）全局指定
REST_FRAMEWORK = {
‘DEFAULT_FILTER_BACKENDS‘: ‘django_filters.rest_framework.backends.DjangoFilterBackend‘
}
b.指定需要过滤的字段，过滤的字段需要与模型类中的字段保持一致
filterset_fields = [‘name‘, ‘leader‘, ‘programmer‘, ‘tester‘]
c.调用self.filter_queryset()方法，传递一个查询集对象，并返回一个查询集
from rest_framework.response import Response
from rest_framework import status
from rest_framework.generics import GenericAPIView
from django_filters.rest_framework import DjangoFilterBackend
from .models import Projects
from .serializers import ProjectsModelSerializer
class ProjectsPage(GenericAPIView):
‘‘‘
类视图
‘‘‘
queryset = Projects.objects.all()
serializer_class = ProjectsModelSerializer
filter_backends = [DjangoFilterBackend]
filterset_fields = [‘name‘, ‘leader‘, ‘programmer‘, ‘tester‘]
def get(self, request):
qs = self.get_queryset()
qs = self.filter_queryset(qs)
serializer_obj = self.get_serializer(instance=qs, many=True)
return Response({‘code‘: 0, ‘res‘: "success", ‘msg‘: serializer_obj.data}, status=status.HTTP_200_OK)
