3.1.cms用户名渲染和注销功能实现

显示登录的用户名

（1）app/cms/hooks.py

from .views import bp import config from flask import session,g from .models import CMSUser @bp.before_request def before_request(): if config.CMS_USER_ID in session: user_id = session.get(config.CMS_USER_ID) user = CMSUser.query.get(user_id) if user: g.cms_user = user

（2）app/cms/init.py

要导入一下才可以，否则不会执行hooks.py里面的代码

import apps.cms.hooks

（3）cms/cms_index.html

<li><a href="#">{{ g.cms_user.username }}<span>[超级管理员]</span></a></li>

注销功能

cms/views.py

@bp.route('/logout/') @login_required def logout(): del session[config.CMS_USER_ID] return redirect(url_for('cms.login'))

cms/cms_index.html

3.2.cms模板抽离和个人信息页面完成

（1）cms/cms_base.html

{% from "common/_macros.html" import static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>{% block title %}{% endblock %}</title> <script src="http://cdn.bootcss.com/jquery/3.1.1/jquery.min.js"></script> <link href="http://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> <script src="http://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <link rel="stylesheet" href="{{ static('cms/css/base.css') }}"> <script src="{{ static('cms/js/base.js')}}"></script> {% block head %}{% endblock %} </head> <body> <nav class="navbar navbar-inverse navbar-fixed-top" role="navigation"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">Zhang_derek论坛管理后台</a> </div> <div id="navbar" class="navbar-collapse collapse"> <ul class="nav navbar-nav navbar-right"> <li><a href="#">{{ g.cms_user.username }}<span>[超级管理员]</span></a></li> <li><a href="{{ url_for('cms.logout') }}">注销</a></li> </ul> <form class="navbar-form navbar-right"> <input type="text" class="form-control" placeholder="查找..."> </form> </div> </div> </nav> <div class="container-fluid"> <div class="row"> <div class="col-sm-3 col-md-2 sidebar"> <ul class="nav-sidebar"> <li class="unfold"><a href="{{ url_for('cms.index') }}">首页</a></li> <li class="profile-li"> <a href="#">个人中心<span></span></a> <ul class="subnav"> <li><a href="{{ url_for('cms.profile') }}">个人信息</a></li> <li><a href="#">修改密码</a></li> <li><a href="#">修改邮箱</a></li> </ul> </li> <li class="nav-group post-manage"><a href="#">帖子管理</a></li> <li class="comments-manage"><a href="#">评论管理</a></li> <li class="board-manage"><a href="#">板块管理</a></li> <li class="nav-group user-manage"><a href="#">用户管理</a></li> <li class="nav-group cmsuser-manage"><a href="#">CMS用户管理</a></li> <li class="cmsrole-manage"><a href="#">CMS组管理</a></li> </ul> </div> <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"> <h1>{% block page_title %}{% endblock %}</h1> <div class="main_content"> {% block main_content %}{% endblock %} </div> </div> </div> </div> </body> </html>

（2）cms/cms_index.html

{% extends 'cms/cms_base.html' %} {% block title %} Zhang_derek论坛管理后台 {% endblock %} {% block page_title %} 我的论坛 {% endblock %}

（3）cms/views.py

@bp.route('/profile/') @login_required def profile(): return render_template('cms/cms_profile.html')

（4）cms/cms_profile.html

{% extends 'cms/cms_base.html' %} {% block title %} 个人信息 {% endblock %} {% block page_title %} {{ self.title() }} {% endblock %} {% block main_content %} {% set user=g.cms_user %} <table class="table table-bordered"> <tbody> <tr> <td>用户名：</td> <td>{{ user.username }}</td> </tr> <tr> <td>邮箱：</td> <td>{{ user.email }}</td> </tr> <tr> <td>角色：</td> <td>xxxxxxx</td> </tr> <tr> <td>权限：</td> <td>xxxxxx</td> </tr> <tr> <td>加入时间：</td> <td>{{ user.join_time }}</td> </tr> </tbody> </table> {% endblock %}
