Linux下开发python django程序(Form表单对象创建和使用)

1.在setting.py文件中修改节点,注释掉其中一行

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    #'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)


2.在urls.py中添加对应的url

 url(r'^app1/register/$', app1.views.register),

3.定义form类对象

class UserForm(forms.Form):
    name=forms.CharField()

 

4.views.py中添加对应url的方法

def register(req):
    if req.method == 'POST':
        form = UserForm(req.POST) #创建 form对象
        if form.is_valid():#验证是否正确
             print form.cleaned_data #打印界面对应取值
            return HttpResponse('ok')
        
    else:
      form = UserForm()
    return render_to_response('register.html',{'form':form})

 

5.在templates中添加对应模板文件

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title></title>
</head>
<body>
<form method="POST">
{{form.as_p}}#as_p 分行显示 默认显示在一行
<input type="submit"  value="ok"  />
</form>
</body>
</html>
