# myapp.models.py from django.contrib.auth.models import AbstractBaseUserclass MyUser(AbstractBaseUser): username = models.CharField(max_length=40, unique=True, db_index=True) email = models.EmailField(max_length=254, unique=True) twitter_handle = models.CharField(max_length=255) ... USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['twitter_handle']
扩展User需要做如下:
这样可以对某些字段，添加些帮助提示信息，也可以添加下方法来设置用户密码，检查用户是否已经激活等等。
这是一个作为User的标识字段，所选的字段来代表这个用户，可以用Email地址也可以选择其他的唯一标识字段。
这个List用来告诉Django，当创建用户时，这里面的字段都是必须输入的。
下面我们需要告诉Django，我们新建了一个User模型来代替默认的模型. 在 settings file如下设置:
# settings.pyAUTH_USER_MODEL = 'myapp.MyUser'
现在Django就会使用这个User模型了.
from django.conf import settingsfrom django.db import modelsclass Post(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL)
其他模型来建立指向User的外键，如上.
现在已经自定义了User，也需要自定义Manager来管理User和SuperUser.如果字段没有什么变化的话，当然也可以使用默认的Manager，如下.
from django.contrib.auth.models import UserManager, AbstractBaseUserclass MyUser(AbstractBaseUser): ... objects = UserManager
如果自定义User里包含了不一样的字段，就需要继承BaseUserManager来自定义Manager了。
from django.contrib.auth.models import BaseUserManager, AbstractBaseUserclass MyUserManager(BaseUserManager): def create_user(self, email, twitter_handle, password=None): if not email: raise ValueError('Users must have an email address') user = self.model( email=MyUserManager.normalize_email(email), twitter_handle=twitter_handle, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, twitter_handle, password): user = self.create_user(email, password=password, twitter_handle=twitter_handle ) user.is_admin = True user.save(using=self._db) return userclass MyUser(AbstractBaseUser): ... objects = MyUserManager 还有一些其他函数需要实装:
User的完整格式的标识符. 一般来说是用户的完整名字。
User的简短格式的标识符.。
一个标准用户是否激活的Bool型，AbstractBaseUser 里默认为true.
# models.pyfrom django.conf import settingsfrom django.db import modelsfrom django.contrib.auth.models import BaseUserManager, AbstractBaseUserclass MyUserManager(BaseUserManager): def create_user(self, email, twitter_handle, password=None): if not email: raise ValueError('Users must have an email address') user = self.model( email=MyUserManager.normalize_email(email), twitter_handle=twitter_handle, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, twitter_handle, password): user = self.create_user(email, password=password, twitter_handle=twitter_handle, ) user.is_admin = True user.save(using=self._db) return userclass MyUser(AbstractBaseUser): email = models.EmailField(max_length=254, unique=True, db_index=True) twitter_handle = models.CharField(max_length=255) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) objects = MyUserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['twitter_handle'] def get_full_name(self): # For this case we return email. Could also be User.first_name User.last_name if you have these fields return self.email def get_short_name(self): # For this case we return email. Could also be User.first_name if you have this field return self.email def __unicode__(self): return self.email def has_perm(self, perm, obj=None): # Handle whether the user has a specific permission?" return True def has_module_perms(self, app_label): # Handle whether the user has permissions to view the app `app_label`?" return True @property def is_staff(self): # Handle whether the user is a member of staff?" return self.is_adminclass Post(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL)#views.pyfrom django.contrib.auth import get_user_model...User = get_user_model()
django使用自己的用户系统
