因为在部署过程中会涉及用户邮件发送，如果有的同事不愿意收到太多邮件，则可以自己定义为不存在的邮箱。
我们在注册的时候，也不会写用户邮箱地址，那么他们也可以在这里自己更改。
changeemail.html模板
{% extends "index.html" %}
{% load staticfiles %}
{% block title %} 修改邮箱 {% endblock %}
{% block content %}
<div class="tm-middle">
<div class="uk-container uk-container-center">

<hr class="uk-grid-divider">

{% if changeemail_success %}
<div class="uk-alert">邮箱更新成功！</div>
{% endif%}
<form class="uk-form uk-form-horizontal uk-margin-top" action="" method="post">

forms.py表单文件：
class UserEmailForm(forms.ModelForm): email = forms.EmailField(required=True) class Meta: model = User fields = ('email',)
views.py文件：
def changeemail(request): if request.POST: user_form = UserEmailForm(request.POST, instance=request.user) if user_form.is_valid(): user_form.save() return render_to_response('changeemail.html', RequestContext(request, {'form': user_form, 'changeemail_success': True})) else: user_form = UserEmailForm() return render_to_response('changeemail.html', RequestContext(request, {'form': user_form, }))
最后，，就简单的弄出来了。
