Django 404 error-page not found

问题

My project is named homefood, and when I runserver I get this error.Anybody have any clue how to fix this error.

Page not found (404)

Request Method: GET

Request URL:    http://127.0.0.1:8000/

Using the URLconf defined in homefood.urls, Django tried these URL patterns, in this order:

^foodPosts/

^admin/

The current URL, , 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.

My settings.py file looks like this...

import dj_database_url
"""
Django settings for homefood project.

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))

    os.path.join(BASE_DIR, 'templates'),

)                                           #static asset configuration

and my urls.py in my homefood folder is

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




from django.contrib import admin
admin.autodiscover()

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


  url(r'^foodPosts/',include('foodPosts.urls')),
  url(r'^admin/', include(admin.site.urls)),


 )

I think my problem is either in my urls.py, or my settings.py but I am unsure. Any help would be greatly appreciated. Thanks.

回答1:

You are getting the 404 because you haven't defined a url pattern for http://127.0.0.1:8000/ yet.

You should be able to view the admin site at http://127.0.0.1:8000/admin/ and your food posts at http://127.0.0.1:8000/foodPosts/.

To add a url pattern for the homepage, uncomment the following entry in your urls.py, and replace homefood.views.home with the path to the view you want to use.

url(r'^$', 'homefood.views.home', name='home'),

Basically the answer to this to add a entry in the project urls.py file as blank example:

path('', include('MYAPP.urls')),

and in the app urls.py you add this

url('MYAPP', views.index),

make sure in the settings.py you include your app also make sure in the app urls.py you import your views
