表单

表单可以验证输入，也可以生成html

<form action="/user_list/" method="post">

<p>用户类型：` obj`.`user_type `

<span>{% error_message errors.user_type %}</span>

</p>

<p>主机：` obj`.`host `

<span>{% error_message errors.host %}</span>

</p>

<p>端口：` obj`.`port ` <span>` errors`.`port `</span></p>

<p>邮箱：` obj`.`email ` <span>` errors`.`email `</span></p>

<p>手机：` obj`.`mobile ` <span>` errors`.`mobile `</span></p>

<p>备注：` obj`.`memo ` <span>` errors`.`memo `</span></p>

<input type="submit" value="submit" />

</form>

#前端提交数据处理函数
