重写第三方应用程序socialauthappDjango使用的create_user（）函数

Question

您好，我有一个项目，我从BaseUserManager继承创建了自己的用户模型

class MyAccountManager(BaseUserManager):
    def create_user(self, email, first_name, last_name, password=None):
        if not email:
            raise ValueError('Este es un campo requerido')
        if not first_name:
            raise ValueError('Este es un campo requerido')
        if not last_name:
            raise ValueError('Este es un campo requerido')

        user = self.model(
            email=self.normalize_email(email),
            first_name=first_name,
            last_name=last_name,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, first_name, last_name, password):
        user = self.create_user(
            email=self.normalize_email(email),
            password=password,
            first_name=first_name,
            last_name=last_name,
        )
        user.is_admin = True
        user.is_staff = True
        user.is_superuser = True
        user.save(using=self._db)
        return user``

现在，我还想为用户添加通过facebook登录的选项，但这给了我一个例外，即create_user（）缺少两个必需的位置参数：“first_name”和“last_name”，因为我修改了模型以请求这些字段，而不是用户名和其他更改。如何使它能够正确地与我的自定义用户模型配合使用

这是完整的回溯：

在阅读了库中的一堆文件后，我发现您只需将以下代码行USER_FIELDS = ['field1', 'field2', ... , 'fieldn']添加到settings.py文件中，就可以告诉应用程序您已经修改了create_user（）函数以获取USER_FIELDS中的字段
