django-rest-auth：自定义注册序列化程序不保存自定义字段

Question

NOT A DUPLICATE

我正在使用 Django 和 ReactJs 构建一个简单的 Todo 应用程序，我运行遇到了 django-rest-auth 的问题。

问题是我的自定义 UserRegisterSerializer 只保存了 request.data 的一个片段而忽略了其余部分。我不知道为什么。

这是我的代码：

用户模型：

class User(AbstractUser):
    id = models.UUIDField(default=uuid.uuid4,
                      primary_key=True, unique=True, editable=False, db_index=True)

    first_name = models.CharField(max_length=100, blank=False)
    last_name = models.CharField(max_length=100, blank=False)

    email = models.EmailField(max_length=247, blank=False, 
                unique=True, error_messages={
                    'unique': _('A user with this email already exists.'),
                    'invalid': _('Invalid e-mail address detected.'),
                    'blank': _('this field may not be blank.')
                })

    phone = models.CharField(max_length=20, blank=True, null=True, 
                unique=True, error_messages={
                     'unique': _('A user with this phone number already exists.'),
                })

    gender = models.CharField(max_length=5, choices=GENDERS, default=NOOP)
    birthday = models.DateField(blank=True, null=True)

    @property
    def user_id(self):
        return self.id

RegisterSerializer（自定义）：

class UserRegisterSerializer(RegisterSerializer):
    first_name = serializers.CharField(
        write_only=True, required=True, max_length=100)
    last_name = serializers.CharField(
        write_only=True, required=True, max_length=100)

    birthday = serializers.DateField(required=True, write_only=True)
    phone = serializers.CharField(max_length=20, write_only=True, 
             validators=[
                    UniqueValidator(
                       User.objects.all(),
                       message=_('A user with this phone number already exists.')
                    )
             ])

    gender = serializers.ChoiceField(
        write_only=True,
        choices=[
            ('NO-OP', 'Rather not tell'),
            ('M', 'Male'),
            ('F', 'Female'),
        ],
        default='NO-OP'
    )

    def get_cleaned_data(self):
        cleaned_data = super().get_cleaned_data()
        cleaned_data['first_name'] = self.validated_data.get('first_name', '')
        cleaned_data['last_name'] = self.validated_data.get('last_name', '')
        cleaned_data['phone'] = self.validated_data.get('phone', '')
        cleaned_data['birthday'] = self.validated_data.get('birthday', '')
        cleaned_data['gender'] = self.validated_data.get('gender', '')
        print(cleaned_data)
        return cleaned_data

print(cleaned_data)的输出：

{'username': 'john_doe', 'password1': 'djangopass', 'email': 'john_doe@email.com', 'first_name': 'John', 'last_name': 'Doe', 'phone': '+555 555 5555', 'birthday': datetime.date(2020, 6, 3), 'gender': 'M'}

保存的用户模型：

我使用自定义 UserAdapter 解决了这个问题。

这是adapter.py的代码：

from allauth.account.adapter import DefaultAccountAdapter
from allauth.account.utils import user_field

class UserAdapter(DefaultAccountAdapter):
    def save_user(self, request, user, form, commit=True):
         data = form.cleaned_data
         birthday = data.get('birthday')
         phone = data.get('phone')
         gender = data.get('gender')
         if birthday:
             setattr(user, 'birthday', birthday)
         if phone:
             user_field(user, 'phone', phone)
         if gender:
             user_field(user, 'gender', gender)
         return super().save_user(request, user, form, commit=commit)

然后在你的 settings.py:

...
ACCOUNT_ADAPTER = 'accounts.adapter.UserAdapter'
...

我使用 CustomRegisterSerializer 中的保存方法调用默认保存方法并更新属性，例如：

我需要填写姓名和个人资料：

class CustomRegisterSerializer(RegisterSerializer):
    first_name = serializers.CharField(required=True)
    last_name = serializers.CharField(required=True)
    profile = serializers.IntegerField(required=True)

    def get_cleaned_data(self):
        super(CustomRegisterSerializer, self).get_cleaned_data()
        return {
            'first_name': self.validated_data.get('first_name', ''),
            'last_name': self.validated_data.get('last_name', ''),
            'email': self.validated_data.get('email', ''),
            'password1': self.validated_data.get('password1', ''),
            'id': self.validated_data.get('id', ''),
            'profile': self.validated_data.get('profile','')
        }
    def save(self, request):
        user = super().save(request)
        user.profile = self.data.get('profile')
        user.save()
        return user
