全面响应的Django REST框架自定义格式 [英] Django REST framework custom format for all out responses
问题描述
在我的项目中,我将DRF用作后端,将Angular用作前端.
In my project I use DRF as backend and Angular as frontend.
Django == 1.10 djangorestframework == 3.7.1
Django==1.10 djangorestframework==3.7.1
我需要DRF的所有回复都采用以下格式.
I need all responses from DRF to be in the following format.
{
"status": "", // 200,400,.....etc
"error": "", // True, False
"data": [], // data
"message": "" // Success messages
}
当前位于
[
{
"id": 1,
"name": ""
},
{
"id": 2,
"name": ""
}
]
应该是
{
"status": "200",
"error": "False",
"data": [
{
"id": 1,
"name": ""
},
{
"id": 2,
"name": ""
}
],
"message": "Success"
}
为此,我编写了一个自定义视图集并覆盖了功能列表,详细信息,创建,更新
for this i have written a custom viewset and overridden the functions list, detail, create, update
class ResponseModelViewSet(viewsets.ModelViewSet):
def list(self, request, *args, **kwargs):
queryset = self.filter_queryset(self.get_queryset())
page = self.paginate_queryset(queryset)
if page is not None:
serializer = self.get_serializer(page, many=True)
return self.get_paginated_response(serializer.data)
serializer = self.get_serializer(queryset, many=True)
custom_data = {
"status": True,
"error": False,
"message": 'message',
"data": serializer.data
}
return Response(custom_data)
def create(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
self.perform_create(serializer)
headers = self.get_success_headers(serializer.data)
custom_data = {
"status": True,
"error": False,
"message": 'message',
"data": serializer.data
}
return Response(custom_data, status=status.HTTP_201_CREATED, headers=headers)
def retrieve(self, request, *args, **kwargs):
instance = self.get_object()
serializer = self.get_serializer(instance)
custom_data = {
"status": True,
"error": False,
"message": 'message',
"data": serializer.data
}
return Response(custom_data)
def update(self, request, *args, **kwargs):
partial = kwargs.pop('partial', False)
instance = self.get_object()
serializer = self.get_serializer(instance, data=request.data, partial=partial)
serializer.is_valid(raise_exception=True)
self.perform_update(serializer)
if getattr(instance, '_prefetched_objects_cache', None):
# If 'prefetch_related' has been applied to a queryset, we need to
# forcibly invalidate the prefetch cache on the instance.
instance._prefetched_objects_cache = {}
custom_data = {
"status": True,
"error": False,
"message": 'message',
"data": serializer.data
}
return Response(custom_data)
在视图中,我使用自定义视图集
and in views i use my custom viewset
from common.baseview import ResponseModelViewSet
class PositionViewsets(ResponseModelViewSet):
serializer_class = PositionSerializer
permission_classes = (IsAuthenticated,)
model = Position
def get_queryset(self):
return Position.objects.filter(order__user=self.request.user)
我不确定这是正确的方法还是其他有效的方法. 无论如何,这适用于我的自定义应用程序,但不适用于身份验证应用程序 我使用了默认的其余应用程序
I am not sure if this is the correct way of doing it or there is some other efficient way to do it. Anyway this works for my custom apps but not for the Authentication app i used the default rest apps
'rest_framework.authtoken',
'rest_auth',
使用用户名和密码登录并获得成功响应,如下所示.
For login using username and password and get the success response as follows.
{
"key": "e642efd0b78e08b57bf34fa999f49b70a7bfe21a"
}
相反,我需要这个.
{
"status": "200",
"error": "False",
"data": [
{
"token":{
"key":"e642efd0b78e08b57bf34fa999f49b70a7bfe21a"
}
}
],
"message": "Login Sucess"
}
错误
{
"status": "error",
"error": "True",
"data": [
{
"email": ["Enter a valid email address."]
}
],
"message": "Login Failed"
}
推荐答案
经过研究,我找到了一种方法.我必须覆盖ModelViewSet
的默认行为才能输出不同的响应.
After some research I found a way to do this. I had to override the default behaviour of the ModelViewSet
to output a different response.
我最初创建了一种自定义的Response
格式:
I created a custom Response
format initially:
class ResponseInfo(object):
def __init__(self, user=None, **args):
self.response = {
"status": args.get('status', True),
"error": args.get('error', 200),
"data": args.get('data', []),
"message": args.get('message', 'success')
}
然后在ModelViewSet
的每种方法中使用此自定义格式:
Then use this custom format in every method of the ModelViewSet
:
class ResponseModelViewSet(viewsets.ModelViewSet):
def __init__(self, **kwargs):
self.response_format = ResponseInfo().response
super(ResponseModelViewSet, self).__init__(**kwargs)
def list(self, request, *args, **kwargs):
response_data = super(ResponseModelViewSet, self).list(request, *args, **kwargs)
self.response_format["data"] = response_data.data
self.response_format["status"] = True
if not response_data.data:
self.response_format["message"] = "List empty"
return Response(self.response_format)
def create(self, request, *args, **kwargs):
response_data = super(ResponseModelViewSet, self).create(request, *args, **kwargs)
self.response_format["data"] = response_data.data
self.response_format["status"] = True
return Response(self.response_format)
def retrieve(self, request, *args, **kwargs):
response_data = super(ResponseModelViewSet, self).retrieve(request, *args, **kwargs)
self.response_format["data"] = response_data.data
self.response_format["status"] = True
if not response_data.data:
self.response_format["message"] = "Empty"
return Response(self.response_format)
def update(self, request, *args, **kwargs):
response_data = super(ResponseModelViewSet, self).update(request, *args, **kwargs)
self.response_format["data"] = response_data.data
self.response_format["status"] = True
return Response(self.response_format)
def destroy(self, request, *args, **kwargs):
response_data = super(ResponseModelViewSet, self).destroy(request, *args, **kwargs)
self.response_format["data"] = response_data.data
self.response_format["status"] = True
return Response(self.response_format)
