*** django 1.1 ***

form 作为 html 提交数据的主要手段，自然希望能有 wrapper class，让起用起来很方便。
django.forms 就是干这个的。

下面举个例子，假设我的 app 叫做 blob。
----------------- blob/forms.py ---------------
from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    message = forms.CharField()
    sender = forms.EmailField()
-----------------------------------------------------------------

----------------- blob/views.py ---------------
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from utftest.blob.forms import ContactForm

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    else:
        form = ContactForm()

    return render_to_response('contact.html', {'form':form})
-----------------------------------------------------------------

----------------- template/contact.html ---------------
<html>
<head>
</head>
<body>
<form action="/contact/" method="POST">
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>
</body>
</html>
-----------------------------------------------------------------

form.as_p 会自动生成对应的 html 代码。
