1、django安装
python 2.6 要使用 Django-1.4.5.tar.gz
[root@localhost 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... [root@localhost ~]# 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
[root@localhost pyfile]# django-admin.py startproject cvst01 [root@localhost cvst01]# pwd /root/pyfile/cvst01 [root@localhost 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
[root@localhost cvst01]# django-admin.py startapp blog
[root@localhost cvst01]# pwd
/root/pyfile/cvst01
[root@localhost cvst01]# ls
blog cvst01 manage.py
[root@localhost cvst01]# cd blog
[root@localhost 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
[root@localhost blog]# pwd
/root/pyfile/cvst01/blog
vi view.py
from django.http import HttpResponse
def index(req):
return HttpResponse('hello welcome to Django
')
[root@localhost cvst01]# ls blog cvst01 manage.py [root@localhost 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('hello welcome to Django
')
”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
CVST
hello everyone!
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
[root@localhost 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
`title`
hello `user`.`name`!
age:`user`.`age`
sex:`user`.`sex`
the `user`.`name` say : `user`.`say`
age:`book_list`.`0`
age:`book_list`.`1`
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})
