1、django安装
python 2.6 要使用 Django-1.4.5.tar.gz
[[email protected] yum.repos.d]# pip install Django==1.4.5 Downloading/unpacking Django==1.4.5 Downloading Django-1.4.5.tar.gz (7.7MB): 7.7MB downloaded Running setup.py (path:/tmp/pip_build_root/Django/setup.py) egg_info for package Django Installing collected packages: Django Running setup.py install for Django changing mode of build/scripts-2.6/django-admin.py from 644 to 755 changing mode of /usr/bin/django-admin.py to 755 Successfully installed Django Cleaning up... [[email protected] ~]# python Python 2.6.6 (r266:84292, Sep 4 2013, 07:46:00) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import django >>>
2、django 使用，第一个project
[[email protected] pyfile]# django-admin.py startproject cvst01 [[email protected] cvst01]# pwd /root/pyfile/cvst01 [[email protected] cvst01]# ls cvst01 manage.py
vi settings.py TIME_ZONE = ‘Asia/Shanghai‘ # Language code for this installation. All choices can be found here: # http://www.i18nguy.com/unicode/language-identifiers.html LANGUAGE_CODE = ‘zh-cn‘ INSTALLED_APPS = ( ‘django.contrib.auth‘, ‘django.contrib.contenttypes‘, ‘django.contrib.sessions‘, ‘django.contrib.sites‘, ‘django.contrib.messages‘, ‘django.contrib.staticfiles‘, ‘blog‘, )
3、第一个web app应用 [[email protected] cvst01]# django-admin.py startapp blog [[email protected] cvst01]# pwd /root/pyfile/cvst01 [[email protected] cvst01]# ls blog cvst01 manage.py [[email protected] cvst01]# cd blog [[email protected] blog]# ls __init__.py models.py tests.py views.py vi urls.py ## 映射一个动作，当访问blog/index的时候，就调用blog应用里面，views模块里的index方法 urlpatterns = patterns(‘‘, # Examples: # url(r‘^$‘, ‘cvst01.views.home‘, name=‘home‘), # url(r‘^cvst01/‘, include(‘cvst01.foo.urls‘)), # Uncomment the admin/doc line below to enable admin documentation: # url(r‘^admin/doc/‘, include(‘django.contrib.admindocs.urls‘)), # Uncomment the next line to enable the admin: # url(r‘^admin/‘, include(admin.site.urls)), url(r‘^blog/index/$‘,‘blog.views.index‘), )
##使用index方法，返回一个HttpResponse [[email protected] blog]# pwd /root/pyfile/cvst01/blog vi view.py from django.http import HttpResponse def index(req): return HttpResponse(‘<h1>hello welcome to Django</h1>‘)
[[email protected] cvst01]# ls blog cvst01 manage.py [[email protected] cvst01]# python manage.py runserver Validating models... 0 errors found Django version 1.4.5, using settings ‘cvst01.settings‘ Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C. [07/Apr/2016 22:08:57] "GET / HTTP/1.1" 404 1900 [07/Apr/2016 22:09:10] "GET /blog/index HTTP/1.1" 301 0 [07/Apr/2016 22:09:10] "GET /blog/index/ HTTP/1.1" 200 32 [07/Apr/2016 22:09:15] "GET /blog/ HTTP/1.1" 404 1915 [07/Apr/2016 22:09:20] "GET /blog/index/ HTTP/1.1" 200 32
4、上面的“
HttpResponse(‘<h1>hello welcome to Django</h1>‘)
”使用文本，现在学习使用html，html文件都是放在app目录的templates下，新建这个目录，在里面加入一个html文件
vi index.html
<html> <head> <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" /> <title>CVST</title> </head> <body> <h1>hello everyone!</h1> </body> </html>
那么映射响应的动作也变了，所以修改views.py，有两种方法，分别导入不同的模块
[[email protected] blog]# cat views.py
第一种
from django.http import HttpResponse
from django.template import loader,Context
def index(req):
t = loader.get_template(‘index.html‘)
c = Context({})
return HttpResponse(t.render(c))
第二种
from django.shortcuts import render_to_response
def index(req):
return render_to_response(‘index.html‘,{})
5、
如何在视图中，动态传入数据
使用模板变量，用{{}}表示
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
<title>{{title}}</title>
</head>
<body>
<h1>hello {{user.name}}!</h1>
<li>age:{{user.age}}</li>
<li>sex:{{user.sex}}</li>
<div>the {{user.name}} say : {{user.say}}</div>
<li>age:{{book_list.0}}</li>
<li>age:{{book_list.1}}</li>
</body>
</html>
class Person(object):
def __init__(self,name,age,sex):
self.name = name
self.age = age
self.sex = sex
def say(self):
return ‘I am ‘ + self.name
#可以接收变量（my page），字典 user{}等，也可以接收对象user
def index(req):
# user = {‘name‘:‘kate‘,‘age‘:‘23‘,‘sex‘:‘male‘}
book_list = [‘Python‘,‘Java‘,‘Shell‘]
user = Person(‘Tom‘,23,‘male‘)
return render_to_response(‘index.html‘,{‘title‘:‘my page‘,‘user‘:user,‘book_list‘:book_list})
