- 显示所有评论
{% for foo in ques.comments %}<ul class="list"> {% for foo in ques.comments %} <li class="post_item"> <a href="{{ url_for(\'usercenter\',user_id=foo.author.id) }}" class="light">{{foo.author.username }}</a> <br> <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>
- 所有评论排序
uquestion = db.relationship(\'Question\', backref=db.backref(\'comments\', order_by=creat_time.desc))class Comment(db.Model): __tablename__=\'comment\' id=db.Column(db.Integer,primary_key=True,autoincrement=True) author_id = db.Column(db.Integer, db.ForeignKey(\'user.id\')) question_id= db.Column(db.Integer, db.ForeignKey(\'question.id\')) create_time = db.Column(db.DateTime, default=datetime.now) detail=db.Column(db.Text,nullable=False) question= db.relationship(\'Question\',backref=db.backref(\'comments\',order_by=create_time.desc)) author= db.relationship(\'User\', backref=db.backref(\'comments\'))
- 显示评论条数
{{ ques.comments|length }}<a href="#" class="post_item_foot">评论:({{ foo.comments|length }})</a>
- 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 %}
