表單
表單可以驗證輸入，也可以生成html
<form action="/user_list/" method="post">
<p>用戶類型：` obj`.`user_type `
<span>{% error_message errors.user_type %}</span>
</p>
<p>主機：` obj`.`host `
<span>{% error_message errors.host %}</span>
</p>
<p>端口：` obj`.`port ` <span>` errors`.`port `</span></p>
<p>郵箱：` obj`.`email ` <span>` errors`.`email `</span></p>
<p>手機：` obj`.`mobile ` <span>` errors`.`mobile `</span></p>
<p>備註：` obj`.`memo ` <span>` errors`.`memo `</span></p>
<input type="submit" value="submit" />
</form>
