$乱码问题
settings.py
LANGUAGE_CODE  =   ' zh-cn '
TIME_ZONE  =   ' Asia/Shanghai '
request.encoding = ' utf8 '  


$python 运行本的命令得到返回参数： 
    fp = os.popen(  " dir  " ,    " r  " )
    x = fp.read() 


$挂载资源
  urls.py patterns  +   (r ' ^$ ' ,  ' test.test.index ' ),


$页面返回
from  django.http  import  HttpResponse
def  index(request):
     return  HttpResponse( " Hello, Django. " )


$取得html访问值
   if  request.POST.has_key( ' a ' )
  int(request.POST[ ' a ' ])

$页面编码设置,文件第一行加入
   # coding=UTF-8


$使用模板
  settings.py TEMPLATE_DIRS   +   ' ./templates ' ,  # 模板路径
   # 方法1
    from  django.shortcuts  import  render_to_response
    def  index(request):
        return  render_to_response( ' list.html ' , { ' address ' : address})
   # templates/list.html
      < h2 > 通讯录 </ h2 >
      < table border = " 1 " >
      < tr >< th > 姓名 </ th >< th > 地址 </ th ></ tr >
     { %   for  user  in  address  % }
      < tr >
      < td > {{ user.name }} </ td >
      < td > {{ user.address }} </ td >
      </ tr >
     { %  endfor  % }
     </ table >
   # 方法2
       from  django.http  import  HttpResponse
     from  django.template  import  loader, Context
    response  =  HttpResponse(mimetype = ' text/csv ' )
    response[ ' Content-Disposition ' ]  =   ' attachment; filename=%s.csv '   %  filename
    t  =  loader.get_template( ' csv.html ' )
    c  =  Context({ ' data ' : address,})
    response.write(t.render(c))
     return  response
      # HTML
    { %   for  row  in  data  % } " {{ row.0|addslashes}} " ,  " {{ row.1|addslashes}} " ,{ %  endfor  % }
    
   
$提供下载
   from  django.template  import  loader, Context
   # 设置返回下载属性
  response  =  HttpResponse(mimetype = ' text/csv ' )
  response[ ' Content-Disposition ' ]  =   ' attachment; filename=%s.csv '   %  filename

$使用session和数据库
    http: // www.woodpecker.org.cn / obp / django / django - stepbystep / newtest / doc / tut05.html

$新建子项目
  settiongs.py  +  INSTALLED_APPS  =   ' 总包名.新建包名 ' ,
  manage.py startapp 包名
