Django中需要解压缩的值太多

Question

我在Django中编辑用户的端点是这样实现的:

@api_view(['PUT'])
@permission_classes([IsAuthenticated])
def updateUser(request, pk):
user = User.objects.get(pk)
data = request.data
user.first_name = data['name']
user.username = data['email']
user.email = data['email']
user.is_staff = data['isAdmin']
user.save()
serializer = UserSerializer(user, many=False)
return Response(serializer.data)

我的用户序列化器是这样实现的:

class UserSerializer(serializers.ModelSerializer):
name = serializers.SerializerMethodField(read_only=True)
_id = serializers.SerializerMethodField(read_only=True)
isAdmin = serializers.SerializerMethodField(read_only=True)
class Meta:
model = User
fields = ['id', '_id', 'username', 'email', 'name', 'isAdmin']
def get__id(self, obj):
return obj.id
def get_isAdmin(self, obj):
return obj.is_staff
def get_name(self, obj):
name = obj.first_name
if name == '':
name = obj.email
return name

我在Redux中向Django发送put请求的操作是这样实现的:

export const updateUser = (user) => async (dispatch, getState) => {
try {
dispatch({
type: USER_UPDATE_REQUEST
})
const {
userLogin: { userInfo
}
} = getState()
const config = {
headers: {
'Content-Type': 'application/json',
Authorization: `Bearer ${userInfo.token}`
}
}
const { data } = await axios.put(
`/api/users/update/${user._id}/`,
user,
config
)
dispatch({
type: USER_UPDATE_SUCCESS,
})
dispatch({
type: USER_DETAILS_SUCCESS,
payload: data
})
} catch (error) {
dispatch({
type: USER_UPDATE_FAIL,
payload: error.response && error.response.data.detail
? error.response.data.detail
: error.message,
})
}
}

我调度updateUser动作在我的组件中的按钮点击，像这样:

const submitHandler = (e) => {
e.preventDefault()
dispatch(updateUser({ _id: user._id, name, email, isAdmin }))
}

get error from Django:

请告诉我问题出在哪里

Answer 1

它位于视图函数的第一行:

user = User.objects.get(pk=pk)

—说明—

.get需要关键字参数
