完成个人中心—导航标签

 

1. 个人中心—视图函数带标签页面参数tag
   @app.route('/usercenter/<user_id>/<tag>')
   def usercenter(user_id, tag):
      if tag == ‘1':
          return render_template('usercenter1.html', **context)

   @app.route('/userr/<user_id>/<tag>')
   @log
   def userr(user_id,tag):
       user=User.query.filter(User.id == user_id).first()
       context ={
           'user':user,
           'questions': user.question,
           'comments':user.comments
       }
       if tag =='1':
           return render_template('center1.html',**context)
       elif tag == '2':
           return render_template('center2.html',**context)
       else:
           return render_template('center3.html',**context)

    

    

2. 个人中心—导航标签链接增加tag参数
   <li role=“presentation”><a href=“{{ url_for(‘usercenter’,user_id = user.id,tag = ‘1’) }}">全部问答</a></li>

   {% extends 'ba.html' %}
   {% block title %}
       ha
   {% endblock %}
   {% block main %}
       <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
   
   
   <ul class="nav nav-pills" style="margin-left: 30%">
       <li><a href="{{ url_for('userr',user_id=user.id,tag = 1) }}">全部问答</a></li>
       <li><a href="{{ url_for('userr',user_id=user.id,tag = 2) }}">全部评论</a></li>
       <li><a href="{{ url_for('userr',user_id=user.id,tag = 3) }}">个人资料</a></li>
   </ul>
   {% block ab %}{% endblock %}
   {% endblock %}

    

3. 个人中心—有链接到个人中心页面的url增加tag参数
   u <a href="{{ url_for('usercenter',user_id = session.get('userid'), tag=1) }}">{{ session.get('user') }}</a>

4. base.html父模板
    {% if username %}
                       <li><a href="{{  url_for('userr',user_id = session.get('id'),tag=1)}}">{{ session.get('user') }}</a></li>
                       <li><a href='{{ url_for('logout') }}'>注销</a></li>
                   {% else %}
                       <li><a href="{{ url_for('zhuce') }}"><span class="glyphicon glyphicon-user"></span> 注册</a></li>
                       <li><a href="{{ url_for('denglu') }}"><span class="glyphicon glyphicon-log-in"></span> 登录</a></li>
                   {% endif %}

    {% for foo in comments %}
                   <li class="list-group-item">
                       <a href="{{  url_for('userr',user_id = foo.author.id,tag='1') }}">{{ foo.author.username }}</a>
                       <span class="badge pull-right">{{ foo.create_time }}</span>
                       <p>{{ foo.detail }}</p>
