Django中form表单修改密码(views视图函数)

# 修改密码视图函数
def changepwd(request):
    # 处理GET请求,直接返回页面
    if request.method == 'GET':
        form = ChangepwdForm()
        return render_to_response('changepwd.html', RequestContext(request, {'form': form, }))
    else:
    # 处理POST请求,
        # 组件校验,将浏览器传的信息通过组件校验
        form = ChangepwdForm(request.POST)
        # 如果信息校验成功
        if form.is_valid():
            # 获取当前登录用户名
            username = request.user.username
            # 获取原来密码
            oldpassword = request.POST.get('oldpassword', '')
            # 验证用户密码正确
            user = authenticate(username=username, password=oldpassword)
            # 如果用户密码正确
            if user is not None and user.is_active:
                # 获取新密码
                newpassword = request.POST.get('newpassword1', '')
                # 设置密码
                user.set_password(newpassword)
                # 保存
                user.save()
                # 修改成功,提醒用户
                return render_to_response('changepwd.html', RequestContext(request, {'changepwd_success': True}))
            # 如果用户密码不正确
            else:
                return render_to_response('changepwd.html', RequestContext(request, {'form': form, 'oldpassword_is_wrong': True}))
        # 如果信息校验失败
        else:
