启动python manage.py runserver
打开127.0.0.1:8000，报错信息如下：
Reverse for 'indextwo' with no arguments not found. 1 pattern(s) tried: ['$index/$']
现象：
无论怎么修改views.py 还是urls.py，报错信息始终存在
问题发现：
项目目录结构如下
myweb ├── db.sqlite3 ├── home │ ├── __init__.py │ ├── admin.py │ ├── apps.py │ ├── migrations │ │ └── __init__.py │ ├── models.py │ ├── tests.py │ ├── urls.py │ └── views.py ├── manage.py ├── myweb │ ├── __init__.py │ ├── settings.py │ ├── urls.py │ ├── wsgi.py ├── static │ ├── images │ │ ├── 55adde120001d34e00410041.png │ │ ├── 55addf800001ff2e14410118.png │ │ ├── 55addfcb000189b314410138.png │ │ ├── background.jpg │ │ ├── body_back.jpg │ │ └── title.ico │ └── jc │ ├── 55ac9a860001a6c500000000.js │ ├── 55ac9ea30001ace700000000.js │ ├── jquery.easing.min.js │ ├── jquery.fancybox.css │ ├── sample-style.css │ ├── scripts.js │ ├── skin.css └── templates ├── index.html ├── index_three.html └── index_two.html
问题就出现在上面的两个urls.py中
在myweb的文件夹下的urls.py中，代码如下：
from django.conf.urls import url, include urlpatterns = [ url(r'^$', include('home.urls')), ]
在home的文件下的urls.py中，代码如下：
from django.conf.urls import url from .views import HomeHtml urlpatterns = [ url(r'^$', HomeHtml().index, name='index'), url(r'^index/$', HomeHtml().index_two, name='indextwo'), url(r'^content/', HomeHtml().content, name='content'), url(r'^showlist/', HomeHtml().showlist, name='showlist') ]
解决：
将规则改为如下，项目正常启动，无报错信息
from django.conf.urls import url, include urlpatterns = [ url(r'^', include('home.urls')), ]
