Question

我想让django休息框架用户注册工作，我被卡住了。我有一个自定义用户，它向django auth用户添加了一个字段，我正在关注此Java tutorial的第一个答案，但是它给了我一个＆＃39; KeyError＆＃39;而且我真的不知道如何解决它。任何帮助表示赞赏！

这是我的模特：

class CustomUser(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)
    birthday = models.DateField()

这里是Serializer：

class CustomUserSerilizer(serializers.Serializer):
    birthday = serializers.DateField()

    class Meta:
        model = CustomUser
        fields = ('birthday')

class UserSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True)
    custUser = CustomUserSerilizer(required=False)


    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'password', 'custUser')

    def create(self, validated_data):
        profile_data = validated_data.pop('custUser')
        user = User.objects.create(**validated_data)
        user.set_password(validated_data['password'])
        user.save()
        Customer.objects.update_or_create(user=user,**profile_data)
        return user

观点：

@api_view(['POST'])
def create_auth(request):
    serialized = UserSerializer(data=request.data)
    if serialized.is_valid():
        serialized.save()
        return Response(serialized.data, status=status.HTTP_201_CREATED)
    else:
        return Response(serialized._errors, status=status.HTTP_400_BAD_REQUEST)

Exception Type: KeyError at /users/register
Exception Value: 'custUser'

Answer 1

custUser = CustomUserSerilizer(required=False)

因此，用户可能会或可能不会将字段custUser作为有效负载传递。由于它是required=False，它只是传递is_valid()，但在profile_data = validated_data.pop('custUser')引发KeyError，因为有效负载不包含任何字段custUser。要避免此错误，请检入def create(self, validated_data)。像这样的东西

if custUser in validated_data:
     profile_data = validated_data.pop('custUser')

但是，从您的模型定义（CustomUser）birthday应该是必填字段。但我不知道为什么在Serializer中你保留了birthday。我希望通过required=False解决您的问题。
