- 完成个人中心
1.个人中心的页面布局（html文件及相应的样式文件）
2.定义视图函数def usercenter(user_id):
3.向前端页面传递参数
4.页面显示相应数据
发布的全部问答
发布的全部评论
个人信息
@app.route(‘/usercenter/<user_id>‘) @loginFirst def usercenter(user_id): user=User.query.filter(User.id==user_id).first() context={ ‘username‘:user.username, ‘questions‘:user.question, ‘comments‘:user.comments } return render_template(‘usercenter.html‘,**context)
{% extends‘base.html‘ %} {% block title %}个人中心 {% endblock %} {% block head %} <link rel="stylesheet" type="text/css" href="{{ url_for(‘static‘,filename=‘css/detail.css‘) }}"> {% endblock %} {% block main %} <div class="post"> <h3 class="title "><span>{{ username }}<br><small>全部问答</small></span></h3> <ul class="list"> {% for foo in questions %} <li class="post_item"> <a href="#" class="light">{{foo.author.username }}</a> <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt=""> <p class="post_item">{{ foo.detail }}</p> <span class="foot">发布于 {{ foo.create_time }}</span> </li> <hr> {% endfor %} </ul> </div> <div class="post"> <h3 class="title "><span></span>{{ user }}<br><small>全部评论 <span></span></small></h3> <ul class="list"> {% for foo in comments %} <li class="post_item"> <a href="#" class="light">{{foo.author.username }}</a> <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt=""> <p class="post_item">{{ foo.detail }}</p> <span class="foot">发布于 {{ foo.create_time }}</span> </li> <hr> {% endfor %} </ul> </div> <div class="post"> <h3 class="title "><span></span>{{ user }}<br><small>个人信息 <span></span></small></h3> <ul> <li class="post_item">用户：{{ username }}</li> <li class="post_item">编号：</li> <li class="post_item">昵称：</li> <li class="post_item">文章数：</li> </ul> </div> {% endblock %}
