Django 管理员注册内联用户配置文件管理员的问题 [英] Issue with Django admin registering an inline user profile admin

问题描述

我目前正在开发一个 django 项目.我正在尝试将 UserProfile 模型内联添加到我的 User 模型中.在我的 models.py 中，我有:

I'm currently working on a django project. I'm attempting to add a UserProfile model inline to my User model. In my models.py I have:

class UserProfile(models.Model):
    '''
    Extension to the User model in django admin.
    '''
    user = models.ForeignKey(User)
    site_role = models.CharField(max_length=128, choices=SITE_ROLE)
    signature = models.CharField(max_length=128)
    position_title = models.CharField(max_length=128)
    on_duty = models.BooleanField(default=False)
    on_duty_order = models.IntegerField()

在我的 admin.py 中有:

In my admin.py I have:

class UserProfileInline(admin.StackedInline):
    model = UserProfile

class UserAdmin(admin.ModelAdmin):
    inlines = [UserProfileInline]


admin.site.unregister(User)
admin.site.register(User, UserAdmin)

当我运行开发服务器时(是的，我已经重新启动它)我得到以下异常:

When I run the development server (yes, I have restarted it) I get the following exception:

NotRegistered at /admin
The model User is not registered

此异常来自 admin.site.unregister(User) 行.

但是，当我注释掉该行时，我得到以下异常:

However, when I comment out that line, I get the following exception:

AlreadyRegistered at /admin
The model User is already registered

我的 django 设置似乎有点两极.我花了一个小时左右的时间研究这个问题，我的代码似乎对其他人来说很好用.有没有人知道为什么会发生这种情况?

Something about my django setup seems to be a little bi-polar. I've spent an hour or so researching this problem and the code I have seems to work great for others. Does anyone have any insight into why this might be happening?

谢谢，特拉维斯

推荐答案

我的猜测是你要么正在做一些疯狂的模块导入......或者......你的 settings.INSTALLED_APPS列表.确保 'django.contrib.auth' 出现在列表中，位于替换默认管理员的应用之前.该列表应如下所示:

my guess is that you either are doing some crazy module importing... or... you have an ordering problem in your settings.INSTALLED_APPS list. Make sure that 'django.contrib.auth' appears on your list before your app that is replacing the default admin. The list should look something like this:

INSTALLED_APPS = (
    # django apps first
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.admin',

    # your stuff from here on
    'yourproject.userstuff',
)

这样 django 的应用程序会注册 User 模型，然后您使用自己的 ModelAdmin 注销并重新注册它.

That way django's app registers the User model, and then you unregister and re-register it with your own ModelAdmin.
