Question

当我在Postman中发布嵌套的序列化程序时，会出现以下错误

"profile": {
    "non_field_errors": [
        "Invalid data. Expected a dictionary, but got list."
    ]
}

但是当我发出GET请求时，它会像这样显示

    "email": null,
    "phone_number": null,
    "profile": {
        "first_name": "Jane",
        "last_name": "Doe",
        "interestlist_set": [
            {
                "interest_list": [
                    2,
                    1
                ],
                "user": 1,
                "category": 1
            }
        ]

我要在上面发布与上面相同的内容，interest_list是ManyToManyField，可能是问题，但我无法解决，这是我的模型

models.py

class InterestName(TimeModel):
   name = models.CharField(max_length=255)

class InterestList(models.Model):
    interest_list = models.ManyToManyField(InterestName)
    user = models.ForeignKey(Profile, on_delete=models.CASCADE)
    category = models.ForeignKey(ListOfInterestCategory, on_delete=models.CASCADE)

class Profile(models.Model):
   user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
   first_name = models.CharField(max_length=30, null=True)
   last_name = models.CharField(max_length=30, null=True)

serializers.py

class ProfileSerializer(serializers.ModelSerializer):
    interestlist_set = InterestListSerializer(many=True)

class Meta:
    model = Profile
    fields = ['first_name', 'last_name', 'interestlist_set',]

class UserRegisterSerializer(serializers.ModelSerializer):
    profile = ProfileSerializer()

class Meta:
    model = CustomUser
    fields = ['email', 'phone_number','profile']

def create(self, validated_data):
    profiles_data = validated_data.pop('profile')
    user = CustomUser.objects.create(**validated_data)
    for profile_data in profiles_data:
        Profile.objects.create(user=user, **profile_data)
    return user

到目前为止，我在这里一直尝试无法在Postman中发出POST请求的方法如何解决此问题？预先感谢！

non_field_errors，无效的数据。 DRF
