- 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
5.各个页面链接到个人中心
@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" href="{{ url_for(‘static‘,filename=‘css/usercenter.css‘)}}" type="text/css"> {% endblock %} {% block main %} <body > <div class="d1"><h3>全部问答</h3> {% for foo in questions%} <hr> <table class="table"> <tr><td> <p>标题：{{ foo.question }}</p> <p>内容：{{ foo.questionDetail }}</p></td></tr> </table> <img class="unicorn" src="{{ url_for(‘static‘,filename=‘images/bulbon.jpg‘) }} " width="20px"><a href="{{ url_for(‘usercenter‘,user_id=foo.author_id) }}" class="name">{{ foo.author.username }} {{ foo.creat_time }}<br></a> {% endfor %}<hr><hr> <h3>全部评论</h3> {% for foo in comments%} <hr> <table class="table" > <tr><td><span class="time" >{{ foo.creat_time }}</span><br> <p>{{ foo.detail }}</p></td></tr> </table> <a href="{{ url_for(‘usercenter‘,user_id=foo.author_id) }}" class="name">{{ foo.author.username }}</a> {% endfor %}<hr><hr> <h3>个人信息</h3><hr> <table class="table" > <tr><td> <li style="list-style:none">用户：{{ username }}</li> <li style="list-style:none">ID号:</li></td></tr> </table> </div> </body> {% endblock %}
