Question

UserProfile模型已将OneToOneField连接到User模型。我想显示嵌套字段中的详细信息。

我使用序列化器来表达嵌套关系。但是结果是一样的。

通过用户实例访问用户配置文件没有问题。例如

user = User.objects.get(username="test")
user.userprofile.super_user = True

有人可以帮我吗？

* models.py *

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
    phone_no = models.CharField(max_length=10, null=True)
    super_user = models.BooleanField(default=False)
    admin_user = models.BooleanField(default=False)

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.userprofile.save()

* serializers.py *

class UserProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserProfile
        fields = ("phone_no", "super_user", "admin_user")


class UserSerializer(serializers.ModelSerializer):
    profile = UserProfileSerializer(read_only=True)
    # SerializerMethodField is read-only
    organization = serializers.SerializerMethodField()

    def get_organization(self, obj):
        if obj.groups is not None:
            return obj.groups.all().first().name
        return None

    class Meta:
        model = User
        fields = (
            "id",
            "profile",
            "username",
            "first_name",
            "last_name",
            "email",
            "organization",
        )

我想获得如下的json格式。

   "user": {
        "id": 1,
        "profile": {
            "phone_no": "",
            "super_user": "",
            "admin_user"
        }
        "username": "testUser",
        "first_name": "",
        "last_name": "",
        "email": "",
        "organization": "testOrg"
    },

但结果不会显示如下所示的“个人资料”字段。

   "user": {
        "id": 1,
        "username": "testUser",
        "first_name": "",
        "last_name": "",
        "email": "",
        "organization": "testOrg"
    },

我更改了与模型名称相同的字段名称后解决了这个问题。

class UserSerializer(serializers.ModelSerializer):
    userprofile = UserProfileSerializer(read_only=True)
    # SerializerMethodField is read-only
    organization = serializers.SerializerMethodField()

    def get_organization(self, obj):
        if obj.groups is not None:
            return obj.groups.all().first().name
        return None

    class Meta:
        model = User
        fields = (
            "id",
            "userprofile",
            "username",
            "first_name",
            "last_name",
            "email",
            "organization",
        )

UserProfile的OneToOneField不显示在结果中
