邮递员formdata中的POST嵌套json

实际上,我想将包含图像的嵌套json发送到在Django中创建用户个人资料图像,而解决的主要问题是我无法填充嵌套对象

这是我的json,以原始模式成功发布:

 {
"id": 1,
"bio": "salam manam",
"user": {
    "username": "amirlesani",
    "first_name": "",
    "password":"somepasword"
    "last_name": "",
    "email": ""
},
"user_type": {
    "user_type": "br"
             }
 }

但是当我想要以这种方式填写表格数据时,它显示了这样的错误 user_type:此字段为必填项! 用户:此字段为必填项!

序列化器:

 class UserProfileSerializer(serializers.HyperlinkedModelSerializer):
    user = UserSerializer()
    user_type = UserTypeSerializer()
    images = ProfileImageSerializer(source='profileimage_set', many=True, read_only=True)

    class Meta:
        model = UserProfile
        fields = ('id', 'bio', 'user', 'images', 'user_type')

    def create(self, validated_data):
        usertype = validated_data.pop('user_type')
        type = UserTypeSerializer.create(UserTypeSerializer(), validated_data=usertype)

        user_data = validated_data.pop('user')
        user = UserSerializer.create(UserSerializer(), validated_data=user_data)

        userprofile = UserProfile.objects.create(user=user, bio=validated_data.pop('bio'), user_type=type)
        images_data = self.context.get('view').request.FILES

        for image_data in images_data.values():
            ProfileImage.objects.create(userprofile=userprofile, image=image_data, user_type=type)

        userprofile.save()
        return userprofile

我找到了解决方案,您必须将imageUploader与嵌套的json区别开,并使用外键将您的图像连接到您的数据
