DJANGO里让用户自助修改密码

参考了网上的实现，最终实现的各代码如下：

changepwd.html模板文件：

{% extends "Prism/index.html" %}
{% load staticfiles %}

{% block title %} 修改密码 {% endblock %}

{% block heading %}

{% endblock %}

{% block content %}
   <div class="tm-middle">
        <div class="uk-container uk-container-center">
            <h3 class="tm-article-subtitle uk-margin-top">
                修改密码
            </h3>
           <hr class="uk-grid-divider">

            <div class="uk-panel uk-panel-box uk-container-center uk-width-1-3">
                <h3 class="uk-panel-title"><i class="uk-icon-user"></i>修改密码</h3>

                    <div class="uk-grid">
                    <div >
                         {% if changepwd_success %}
                            <div class="uk-alert">密码更改成功，请用新的密码登陆！</div>
                        {% endif%}
                    <form class="uk-form uk-form-horizontal uk-margin-top" action="" method="post">
