2.urls
[python]  
from django.conf.urls.defaults import patterns, include, url   
from django.contrib import admin  
admin.autodiscover()

    name = forms.CharField(initial='aaa',label='姓名',min_length = 4,max_length = 16)#initial可以提供初始值  
    mail = forms.EmailField()  
    sex  = forms.ChoiceField(choices=(('m','male'),('f','female')))  
    marry= forms.BooleanField(required = False)  
    birth= forms.DateField(initial = '2012-12-24')  
    intr = forms.CharField(widget = forms.Textarea())  
  
def login(req):  
    if req.method == 'POST':                     #如果是post，就绑定  
        userForm = UserForm(req.POST)            #类的实例化//bind,把req封装在form里  
        if userForm.is_valid():  
            name = req.POST.get('name')          #第一种得到方式,得到的是字符串,不推荐  
            mail = userForm.cleaned_data['mail'] #第二种得到方式，得到的是python格式  
            data=userForm.cleaned_data.items()   #第三种得到方式  
            return HttpResponse(data)
