一：使用forms类实现表单
1：我们一般把Form类都放到一个文件中：forms.py。具体可存放`在APP的目录，如我的APP为BOOKS目录中。
在forms.py里添加：
from django import forms class ContactForm(forms.Form): subject = forms.CharField() email = forms.EmailField(required=False) message = forms.CharField()
每一个字段都默认是必填。要使email成为可选项，我们需要指定required=False。
2：在视图里调用forms,在views里添加
from django.shortcuts import render_to_response
from mysite.contact.forms import ContactForm
def contact(request):
if request.method == ‘POST‘:
form = ContactForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
send_mail(
cd[‘subject‘],
cd[‘message‘],
cd.get(‘email‘, ‘[email protected]‘),
[‘[email protected]‘],
)
return HttpResponseRedirect(‘/contact/thanks/‘)
else:
form = ContactForm()
#必须加最后一句否则或出错return render_to_response(‘contact/contact_form.html‘, {‘form‘: form}，context_instance=RequestContext(request))
3：我们在templates里新建表单目录和表单文件，目录位置/templates/contact/contact_form.html
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">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<input type="submit" value="Submit">
</form>
</body>
</html>
4：在url里添加view路径，就可以访问了
