python - Python 错误：未定义名称“管理员”

Question

我第一次在 Django 中创建 Python 应用程序。我知道我必须取消注释 urls.py 中的管理工具，我已经这样做了。我也加了autodiscover。每次我尝试向管理面板添加新功能时，都会收到此错误：

“NameError：名称'admin'未定义”

这是我在模型中使用以添加到管理面板的代码：

class ChoiceInline(admin.StackedInline):
    model = Choice
    extra = 3

    class PollAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

这是我正在使用的python终端中的代码

admin.site.register(Poll, PollAdmin)

这是我的 urls.py 中的代码：

from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'iFriends.views.home', name='home'),
    # url(r'^iFriends/', include('iFriends.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
    )

有人知道为什么找不到管理员名称吗？

编辑

这是我的整个模型文件：

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    def __unicode__(self):
        return self.question
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

    class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField()
    def __unicode__(self):
        return self.choice_text


#COMMENTED OUT UNTIL I FIX THE ADMIN NAME
from django.config import admin

class ChoiceInline(admin.StackedInline):
    model = Choice
    extra = 3

    class PollAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

#ADD THIS TO THE MAIN PYTHON FUNCTION
admin.site.register(Poll, PollAdmin)

Answer 1

from django.config import admin应该from django.contrib import admin

Answer 2

在**url.py**文件顶部，添加以下代码

from django.contrib import admin
admin.autodiscover()

因此，该特定块应如下所示

---

from django.conf.urls import patterns, include, url
**from django.contrib import admin
admin.autodiscover()**

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'examplesite.views.home', name='home'),
    # url(r'^examplesite/', include('examplesite.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    #url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
**url(r'^admin/', include(admin.site.urls)),**

)

Answer 3

我像这样更改我的 urls.py ......这应该是基本格式

from django.conf.urls import  include, url
from django.contrib import admin

admin.autodiscover()
urlpatterns = [
     url(r'^admin/', include(admin.site.urls)),
    ]

Answer 4

经过漫长而痛苦的寻求解决这个愚蠢的问题，我终于找到了答案！另一个 Django 程序员遇到了同样的问题，发现了这个：

在 ChoiceInLine 的父级中（您将在本教程中看到“admin.StackedInline”），StackedInline 中的 L 不应该大写……就这么简单……非常感谢 Karen Tracey……

Answer 5

我怀疑您from django.contrib import admin的模型文件中没有定义ModelAdmin类的class ChoiceInline(admin.StackedInline):.

Answer 6

您应该将管理员代码（#COMMENTED OUT 直到我修复管理员名称之后的所有内容）放到 admin.py

Answer 7

为我解决这个问题的一种方法是在开头添加这个admin.py：

from django.contrib import admin
