覆盖第三方应用程序social-auth-app-django使用的create_user函数

问题描述

您好，我有一个项目，在其中创建了从BaseUserManager继承的自己的用户模型。

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,password):
        user = self.create_user(
            email=self.normalize_email(email),password=password,)
        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，说create_user（）缺少2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。我该如何做才能使其与我的自定义用户模型一起正常工作？

这是完整的追溯：

解决方法

我在读取了库中的一堆文件后才发现它，原来您只需要向您的USER_FIELDS = ['field1','field2',...,'fieldn']文件中添加以下代码行settings.py即可告诉应用程序您已经修改了create_user（）函数以使用USER_FIELDS中的字段。
