Django - 用户名为unicode [英] Django - User full name as unicode

问题描述

我有许多模型链接到用户，我希望我的模板总是显示他的full_name（如果可用）。有没有办法更改默认的用户 __ unicode __（）？或者还有另一种方法吗？

I have many Models linked to User and I'd like my templates to always display his full_name if available. Is there a way to change the default User __unicode__() ? Or is there another way to do it ?

我有一个配置文件模型注册我可以定义 __ unicode __（），我应该链接所有的模型吗？似乎不是一个好主意。

I have a profile model registered where I can define the __unicode__(), should I link all my models to it ? Seems not a good idea to me.

想象一下，我需要显示此对象的表单

Imagine I need to display the form for this object

class UserBagde
    user = model.ForeignKey(User)
    badge = models.ForeignKey(Bagde)

我将不得不选择每个对象的 __ unicodes __ t
如何在用户的全名？

I will have to select box with __unicodes__ of each object, won't I ?
How can I have full names in the user's one ?

推荐答案

尝试这样： / p>

Try this:

User.full_name = property(lambda u: u"%s %s" % (u.first_name, u.last_name))

编辑

显然你想要的存在..

EDIT

Apparently what you want already exists..

https://docs.djangoproject.com/en/dev/topics/auth/#django.contrib.auth.models.User.get_full_name

如果unicode的必要条件功能被替换：

if its imperative that the unicode function be replaced:

def user_new_unicode(self):
    return self.get_full_name()

# Replace the __unicode__ method in the User class with out new implementation
User.__unicode__ = user_new_unicode 

# or maybe even
User.__unicode__ = User.get_full_name()

如果名称字段为空，则回退

Fallback if name fields are empty

def user_new_unicode(self):
    return self.username if self.get_full_name() == "" else self.get_full_name()

# Replace the __unicode__ method in the User class with out new implementation
User.__unicode__ = user_new_unicode
