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('/usercenter/<user_id>/<tag>')
@login_re
def usercenter(user_id,tag):
    user=User.query.filter(User.id==user_id).first()
    context={
        # 'username':user.Username,
        # 'questions':user.question,
        # 'comments':user.comments

        'user':user
    }
    # return render_template('usercenter.html', **context)
    if tag == '1':
        return render_template('user1.html', **context)
    elif tag == '2':
        return render_template('user2.html', **context)
    else:
        return render_template('user3.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>

 <div class="nav1">
        <ul>
            <li role="presentation"><a href="{{ url_for('usercenter',user_id=user.id ,tag='1')}}">全部问答</a></li>
            <li role="presentation"><a href="{{ url_for('usercenter',user_id=user.id ,tag='2')}}">全部评论</a></li>
            <li role="presentation"><a href="{{ url_for('usercenter',user_id=user.id ,tag='3')}}">个人资料</a></li>
        </ul>
    </div>

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

<a href ="{{ url_for('usercenter',user_id=foo.author_id ,tag=1)}}">{{ foo.author.Username }}

<a href="{{ url_for('usercenter',user_id=foo.author_id,tag=1 )}}">{{ foo.author.Username }}</a>

<small><a href="{{ url_for('usercenter',user_id=ques.author_id,tag=1) }}">{{ ques.author.Username }}</a>
