Extending the User model with custom fields in Django
使用自定义字段扩展用户模型(与Django的身份验证应用程序捆绑在一起)的最佳方法是什么？我也可能想使用电子邮件作为用户名(用于身份验证)。 我已经看到了一些方法，但无法决定哪一种是最好的。
Django推荐的最不痛苦的方法是通过OneToOneField(User)属性。
Extending the existing User model
…
If you wish to store information related to User, you can use a one-to-one relationship to a model containing the fields for additional information. This one-to-one model is often called a profile model, as it might store non-auth related information about a site user.
号 也就是说，扩展EDOCX1[1]并取代它也有效…
Substituting a custom User model
Some kinds of projects may have authentication requirements for which Django’s built-in User model is not always appropriate. For instance, on some sites it makes more sense to use an email address as your identification token instead of a username.
[Ed: Two warnings and a notification follow, mentioning that this is pretty drastic.]
号 我绝对不会更改Django源代码树中的实际用户类和/或复制和更改auth模块。
注意：此答案已弃用。如果您使用的是django 1.7或更高版本，请参阅其他答案。 我就是这样做的。

| #in models.py
from django.contrib.auth.models import User
from django.db.models.signals import post_save
class UserProfile(models.Model):
user = models.OneToOneField(User)
#other fields here
def __str__(self):
return"%s's profile" % self.user
def create_user_profile(sender, instance, created, **kwargs):
if created:
profile, created = UserProfile.objects.get_or_create(user=instance)
post_save.connect(create_user_profile, sender=User)
#in settings.py
AUTH_PROFILE_MODULE = 'YOURAPP.UserProfile' |
这将在每次保存用户时创建一个用户配置文件(如果已创建)。然后你可以使用
1
| user.get_profile().whatever |
号 这是从医生那里得到的更多信息 http://docs.djangoproject.com/en/dev/topics/auth/存储有关用户的其他信息 更新：请注意，由于v1.5:https://docs.djangoproject.com/en/1.5/ref/settings/auth profile module，因此不推荐使用AUTH_PROFILE_MODULE。
好吧，从2008年以来已经过去了一段时间，现在是时候换个新答案了。自Django1.5以来，您将能够创建自定义用户类。实际上，在我写这个的时候，它已经合并到master中了，所以你可以试试看。 在文档中有一些关于它的信息，或者如果您想深入了解它，在这个提交中。 您所要做的就是将AUTH_USER_MODEL添加到带有自定义用户类路径的设置中，它可以扩展AbstractBaseUser(更可自定义的版本)或AbstractUser(您可以扩展多少个旧的用户类)。 对于那些懒于点击的人，下面是代码示例(取自文档)：

由于django 1.5，您可以轻松地扩展用户模型并在数据库中保留一个表。

。 还必须将其配置为设置文件中的当前用户类

如果你想增加很多用户的偏好，OneTooneField选项可能是一个更好的选择。 开发第三方库的人员注意：如果您需要访问用户类，请记住，用户可以更改它。使用官方助手获得正确的课程

。
关于存储有关用户的附加信息，有一个官方建议。Django的书也在章节简介中讨论了这个问题。
下面是扩展用户的另一种方法。我觉得它比上述两种方法更清晰、更容易阅读。 http://scottbarnham.com/blog/2008/08/21/extending-the-django-user-model-with-inheritance/ 使用上述方法：
你不需要使用user.get_profile().newattribute访问附加信息与用户相关
您可以直接访问其他新属性通过user.newattribute
每次使用django post save信号创建用户时，只需创建一个新条目即可扩展用户配置文件。 型号.py

这将在创建新用户时自动创建员工实例。 如果希望扩展用户模型并希望在创建用户时添加更多信息，可以使用django betterforms(http://django betterforms.readthedocs.io/en/latest/multiform.html)。这将创建一个用户添加表单，其中包含在用户配置文件模型中定义的所有字段。 型号.py

Django1.5中的新功能，现在您可以创建自己的自定义用户模型(在上述情况下，这似乎是一件好事)。请参阅"在Django中自定义身份验证" 可能是1.5版本中最酷的新功能。
这就是我所做的，在我看来，这是最简单的方法。为新的自定义模型定义对象管理器，然后定义模型。
