Django基于类视图实现增删改查

第一步：导入View

from django.views import View

第二步：新建这个基类

class CLS_executer(View):
    db = DB_executer

    def get(self, request):
        executer_list = list(self.db.objects.all().values())
        return HttpResponse(json.dumps(executer_list), content_type='application/json')

    def post(self, request):
        data = json.loads(request.body)
        self.db.objects.create(**data)
        return self.get(request)

    def put(self, request):
        data = json.loads(request.body)
        self.db.objects.filter(id=int(data['id'])).update(**data)
        return self.get(request)

    def delete(self, request):
        id = request.GET['id']
        self.db.objects.filter(id=int(id)).delete()
        return self.get(request)

第三步：去urls.py中设置好类视图映射

urlpatterns = [
    path('executer/', CLS_executer.as_view())
]

第四步：校验

get方法直接浏览器请求：{服务器ip:端口号}/executer就行，post、put、delete可以用postman校验
