Django 127.0.0.1:8000/admin/ 停止工作

Question

不确定我做了什么来破坏管理站点，但转到 127.0.0.1:8000/admin/ 不起作用，并在下面的屏幕截图中显示错误：

这是两个 urls.py 文件：

我的项目/urls.py

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

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

和product_app urls.py：

from django.conf.urls import url
from django.conf import settings
from django.views.static import serve
from . import views
from .views import *

urlpatterns = [

    url(r'^$', views.HomePage.as_view(), name='home'),
    url(r'^contact/$', views.contact, name='contact'),
    url(r'^subscribe/$', views.subscribe, name='subscribe'),
    url(r'^products/$', views.products, name = 'products'),
    url(r'^product/$', ProductListView.as_view(), name='product_list'),
    url(r'^user/(\w+)/$', views.profile, name='profile'),
    url(r'post_url/', views.post_product, name='post_product'),
    url(r'^([0-9]+)/$', views.detail, name = 'detail'),
    url(r'^login/$', views.login_view, name='Login'),
    url(r'^logout/$', views.logout_view, name='Logout'),
    url(r'^like_product/$', views.like_product, name='like_product' ),

    url(r'^profile/edit/$', views.edit_profile, name='edit_profile'),

    url(r'^(?P<pk>\d+)/edit/$', PostUpdateView.as_view(), name='product-edit'),
    url(r'^(?P<pk>\d+)/delete/$', PostDeleteView.as_view(), name='product-delete'),
]

if settings.DEBUG:
    urlpatterns += [
        url(r'^product/(?P<path>.*)$', serve, {
            'document_root': settings.MEDIA_ROOT,
        }),
    ]

...以防万一，models.py：

from django.db import models
from django.contrib.auth.models import User
from django.core.urlresolvers import reverse


def get_image_path(instance, filename):
    return '/'.join(['product_images', str(instance.name), filename])


class Product(models.Model):
    user = models.ForeignKey(User)
    name = models.CharField(max_length=100)
    description = models.CharField(max_length=300)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    url = models.CharField(max_length=200)
    product_type = models.CharField(max_length=100)
    image = models.ImageField(upload_to='product_images', blank=True, null=True)
    image_url = models.CharField(max_length=200, blank=True)
    likes = models.IntegerField(default=0)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('index', kwargs={})

...最后，我的views.py：

我不知道我做了什么改变以使管理站点无法工作 - 感谢您提供任何帮助！

检查您的 ROOT_URLCONF 设置 - 它需要设置为 myproject.urls，但看起来它当前设置为 product_app.urls。
