Question

我试图在Django中创建自定义用户模型，然后根据django-rest-auth提供的内容创建RESTAPI。

CustomUserModel和CustomUSerManager定义为-

   from django.contrib.auth.models import (
      BaseUserManager, AbstractBaseUser
  )

class UserManager(BaseUserManager):
use_in_migrations = True

def create_user(self, email, name, phone_no, user_android_id, user_fcm_token,
                user_social_flag, user_fb_id, user_android_app_version, password=None):
    user = self.model(
        email = self.normalize_email(email),
        phone_no = phone_no,
        password=password,
        user_android_id = user_android_id,
        user_fcm_token = user_fcm_token,
        user_social_flag = user_social_flag,
        user_fb_id = user_fb_id,
        user_android_app_version = user_android_app_version,
        name = name,
    )
    # user.is_staff = False
    # user.is_superuser = True
    user.set_password(password)
    user.save(using=self._db)
    return user

def create_staffuser(self, email, name, phone_no, user_android_id, user_fcm_token,
                user_social_flag, user_fb_id, user_android_app_version, password):
    user = self.create_user(
        email,
        password=password,
        phone_no=phone_no,
        user_android_id=user_android_id,
        user_fcm_token=user_fcm_token,
        user_social_flag=user_social_flag,
        user_fb_id=user_fb_id,
        user_android_app_version=user_android_app_version,
        name=name,
    )
    user.is_staff = True
    user.is_admin = False
    user.is_superuser = True
    user.save(using=self._db)
    return user

def create_superuser(self, email, name, phone_no, user_android_id, user_fcm_token,
                user_social_flag, user_fb_id, user_android_app_version, password):
    user = self.create_user(
        email,
        password=password,
        phone_no=phone_no,
        user_android_id=user_android_id,
        user_fcm_token=user_fcm_token,
        user_social_flag=user_social_flag,
        user_fb_id=user_fb_id,
        user_android_app_version=user_android_app_version,
        name=name,
    )
    user.is_admin = True
    user.save(using=self._db)
    return user


class User(AbstractBaseUser):
   objects = UserManager()

   name = models.CharField(max_length=100, blank=True, null=True)
   email = models.EmailField(unique=True)
   created_at = models.DateField(blank=True, null=True)
   phone_no = models.BigIntegerField(blank=True, null=True)
   user_android_id = models.CharField(max_length=255, blank=True, null=True)
   user_fcm_token = models.CharField(max_length=255, blank=True, null=True)
   user_social_flag = models.IntegerField(blank=True, null=True)
   user_fb_id = models.CharField(max_length=255, blank=True, null=True)
   user_android_app_version = models.CharField(max_length=25, blank=True, null=True)

   USERNAME_FIELD = 'email'

   def __str__(self):  
      return self.email

自定义视图文件：

from rest_auth.registration.views import RegisterView
from app.models import User

class CustomRegisterView(RegisterView):
    queryset = User.objects.all()

在settings.py文件中，我已设置：

AUTH_USER_MODEL = 'app.User'
ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_AUTHENTICATION_METHOD = 'email'
ACCOUNT_EMAIL_VERIFICATION = 'none'
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_UNIQUE_EMAIL = True
ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_USER_EMAIL_FIELD = 'email'
ACCOUNT_LOGOUT_ON_GET = True


 REST_AUTH_SERIALIZERS = {
   "USER_DETAILS_SERIALIZER": 
  "app.serializers.CustomUserDetailsSerializer",
 }
REST_AUTH_REGISTER_SERIALIZERS = {
    "REGISTER_SERIALIZER": 
  "app.serializers.CustomRegisterSerializer",
 }

我已经在网址文件中设置了网址。

re_path(r'^registration/$', views.CustomRegisterView.as_view())

当我运行/ registration /网址并填写所有详细信息时，我会收到错误消息：

django.db.utils.IntegrityError：“ is_superuser”列中的空值违反了非空约束详细信息：失败行包含（8，pbkdf2_sha256 $ 120000 $ VpGItoUPHoJ9 $ yBQB2PqRDiqd4SQ2cDZX / wzaV3yFSf ...，null，null，null，null，null，null，null，null，null，null，null，custom@user.com，null，null，null，null， null，null，null，null）。

我在这里想念什么？

更新1：

在检查数据库记录时，我发现仅电子邮件，密码和last_login字段仅被插入，其余全部为空。可能是什么原因？

更新2：

CustomRegisterSerializer类：-

   class CustomRegisterSerializer(RegisterSerializer):
    email = serializers.EmailField()
    password1 = serializers.CharField(write_only=True)
    name = serializers.CharField()
    phone_no = serializers.IntegerField()
    user_android_id = serializers.CharField()
    user_fcm_token = serializers.CharField(required=True)
    user_social_flag = serializers.IntegerField()
    user_fb_id = serializers.CharField(required=True)
    user_android_app_version = serializers.CharField()

    class Meta:
        model = User
        fields = ('email', 'name', 'phone_no', 'user_android_id', 'user_fcm_token',
                  'user_social_flag', 'user_fb_id', 'user_android_app_version')

    def get_cleaned_data(self):
        super(CustomRegisterSerializer, self).get_cleaned_data()

        return {
            'password1': self.validated_data.get('password1', ''),
            'email': self.validated_data.get('email', ''),
            'phone_no': self.validated_data.get('phone_no'),
            'name': self.validated_data.get('name'),
            'user_android_id': self.validated_data.get('user_android_id'),
            'user_fcm_token': self.validated_data.get('user_fcm_token'),
            'user_social_flag': self.validated_data.get('user_social_flag'),
            'user_fb_id': self.validated_data.get('user_fb_id'),
            'user_android_app_version': self.validated_data.get('user_android_app_version'),

        }

在create_user中，您评论了is_staff和is_superuser。取消注释并将它们设置为False。

编辑：

关于字段未进入数据库-is_staff和is_superuser在用户模型中未定义，在AbstractBaseUser中也未定义。这很奇怪，因为在这种情况下，您不应该首先获得该异常。

您是刚开始项目还是在交换用户模型之前进行了迁移？如果您从Django的默认用户模型开始，则需要做更多的工作。希望您还没有真正的用户，并且可以快速完成。请仔细查看topic in Django docs。
