django表单模块学习
直接上配置:
url配置
[root@ns2 app]# cat app/urls.py
from django.conf.urls import patterns, include, url
from web import views
urlpatterns = patterns('',
url(r'^$', views.test),
)
视图函数配置
[root@ns2 web]# cat views.py
from web.forms import ContactForm
from django.http import HttpResponse
from django.shortcuts import render_to_response
def test(request):
if request.method == 'POST':
form = ContactForm(request.POST)
if form.is_valid():
subject = form.cleaned_data['subject']
message = form.cleaned_data['message']
email = form.cleaned_data['email']
return HttpResponse("%s%s%s"%(subject , message , email))
else:
form = ContactForm(
)
return render_to_response('contact_form.html', {'form': form})
表单项配置

模板内容配置:
[root@ns2 app]# cat templates/contact_form.html
<html>
<head>
<title>Contact us</title>
</head>
<body>
<h1>Contact us</h1>
{% if form.errors %}
<p style="color: red;">
Please correct the error{{ form.errors|pluralize }} below.
</p>
{% endif %}
<form action="" method="post">
<table>
{{ form.as_table }}
</table>
<input type="submit" value="Submit">
</form>
</body>
</html>
