如果用户发送POST请求以创建作业,但该作业已存在 - 我正在尝试返回202.
相反,它返回400 ..
视图
def post(self, request, format=None):
serializer = CreateJobSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
else:
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
串行
class CreateJobSerializer(GenericSerializer):
class Meta:
model = Job
fields = ('name')
def create(self, validated_data):
try:
obj = Job.objects.create(**validated_data)
return obj
except:
return Response(serializer.errors, status=status.HTTP_202_ACCEPTED)
我假设如果在该模型上违反了unique = true,Job.objects.create将失败,如果是这种情况我会期望返回202。我做错了什么?
是否因为在验证期间实际捕获了unique = true错误,所以实际上从未调用create()?
答案 0 :(得分:0)
我认为你可以capture the Validation Error然后根据自己想要的状态制作自定义回复(在这种情况下为202)。
我还没试过,但这可能有用:
try:
if (serializer.is_valid(raise_exception=True)):
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
except ValidationError as msg:
if str(msg) == "This Email is already taken":
return Response(
{'ValidationError': str(msg)},
status=status.HTTP_202_ACCEPTED
)
else:
return Response(
{'ValidationError': str(msg)},
status=status.HTTP_400_BAD_REQUEST
)
