django初体验

创建项目

$ django-admin.py startproject myblog
$ cd myblog/
$ tree
.
├── manage.py
└── myblog
    ├── __init__.py
    ├── settings.py
    ├── urls.py
    └── wsgi.py

manage.py - 项目的命令管理器

$ python manage.py runserver
Validating models...

Django version 1.6.11, using settings 'myblog.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

这样就可以访问网站了

项目下创建应用

myblog$ python manage.py startapp blog
myblog$ tree -I *.pyc      # 不列出pyc文件
.
├── blog
│   ├── __init__.py
│   ├── admin.py
│   ├── models.py
│   ├── tests.py
│   └── views.py
├── manage.py
└── myblog
    ├── __init__.py
    ├── settings.py
    ├── urls.py
    └── wsgi.py

一定记得在settings.py中把新创建的应用加入

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

编写传说中的Hello World

编写blog/views.py，添加以下内容

from django.http import HttpResponse

def index(request):
    return HttpResponse('Hello, world!')

修改myblog/urls.py

import blog.views as bv

admin.autodiscover()

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

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

启动服务器，Hello world就完成了

$ python manage.py runserver
