django系列（二）

增加app

一个网站可能有多个功能，以app为单位，模块化的管理，而不是将所有的丢到一个文件夹，

创建app west

[root@centos6 mysitetest]# python manage.py startapp west
[root@centos6 mysitetest]# tree  west/
west/
├── admin.py
├── __init__.py
├── models.py
├── tests.py
└── views.py
0 directories, 5 files
[root@centos6 mysitetest]# ls
db.sqlite3  manage.py  mysitetest  west
[root@centos6 mysitetest]# tree
.
├── db.sqlite3
├── manage.py
├── mysitetest
│?? ├── __init__.py
│?? ├── __init__.pyc
│?? ├── settings.py
│?? ├── settings.pyc
│?? ├── urls.py
│?? ├── urls.pyc
│?? ├── views.py
│?? ├── views.pyc
│?? ├── wsgi.py
│?? └── wsgi.pyc
└── west
    ├── admin.py
    ├── __init__.py
    ├── models.py
    ├── tests.py
    └── views.py
2 directories, 17 files

我们还要修改项目project设置，说明我们要使用west，在mysitetest/setting.py

增加app：west

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'west',
)

增加APP页面

在west/urls.py中设置URL访问对象，

修改mysitetest/urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mysitetest.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', 'mysitetest.views.first_page'),
    url(r'^west/', include('west.urls')),
)

在最后一行添加

url(r'^west/', include('west.urls')),

创建west/urls.py

from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mysitetest.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^$', 'west.views.first_page'),
)

在west下，修改views.py为

# -*- coding: utf-8 -*-
from django.http import HttpResponse
# Create your views here.
def first_page(request):
        return HttpResponse("<p>西餐</p>")
