Django Heroku deployment URLconf error.找不到页面 (404)

Question

我是Django的新手，并试图在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((，因为它对其他人有效，但它对我不起作用。

这是我 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 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，因为您在第一个代码块中设置了它们的路径。

要添加根路径，请尝试如下操作：

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定向到您的管理页面。
