Django Heroku 部署 URLconf 错误。找不到页面 (404)

Question

我是 Django 的新手，正在尝试在 Heroku 上部署我的 Django 应用程序。我按照教程做了所有事情，但是当我终于准备好部署我的应用程序时，我收到错误“找不到页面”。

我尝试删除我的 admin.site.urls 周围的 include()，因为它对其他人有用，但对我不起作用。

这是我的 urls.py 文件：

 from django.contrib import admin
 from django.urls import path, include
 from django.conf import settings
 from django.conf.urls.static import static
 from profiles.views import delete



 urlpatterns = [
 path(r'^profiles/', include('profiles.urls')),
 path(r'^admin/', admin.site.urls),

] + static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT)

这是我的 settings.py 文件：

import os
import django_heroku
import django
os.environ['DJANGO_SETTINGS_MODULE'] = 'firstDjango.settings'
from django.core.wsgi import get_wsgi_application 

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

 STATIC_TMP = os.path.join(BASE_DIR, 'static')


 MEDIA_URL = "/media/"
 MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

 django_heroku.settings(locals())

这是详细错误：

 Page not found (404)
 Request Method:    GET
 Request URL:   https://ewuradjango.herokuapp.com/
 Using the URLconf defined in firstDjango.urls, Django tried these URL patterns, in this order:
 ^profiles/
 ^admin/
 ^media/(?P<path>.*)$
 The empty path didn't match any of these.
 You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a      standard 404 page.

Answer 1

看起来您还没有为根路径“/”设置路由。尝试访问 https://ewuradjango.herokuapp.com/admin 或 https://ewuradjango.herokuapp.com/profiles，因为您已经在第一个代码块中为它们设置了路径。

要添加根路径，请尝试以下操作：

urlpatterns = [
    path(r'', admin.site.urls),
    path(r'^profiles/', include('profiles.urls')),
    path(r'^admin/', admin.site.urls),
] + static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT)

这应该将您的根路径指向您的管理页面。
