1.显示所有评论
{% for foo in ques.comments %}
<ul class="list-group" style="margin: 10px"> {% for foo in questions.comments %} <li class="list-group-item"> <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span> <a href="#">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> <p style="..."> {{ foo.detail }}</p> </li> {% endfor %} </ul>
2.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‘)) creat_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=creat_time.desc)) author = db.relationship(‘User‘,backref = db.backref(‘comments‘))
3.显示评论条数
{{ ques.comments|length }}
<h4>评论({{ questions.comments|length }})</h4>

b.定义视图函数def usercenter(user_id):
c.向前端页面传递参数
d.页面显示相应数据

{% extends ‘base.html‘ %} {% block title %}个人中心{% endblock %} {% block main %} <div class="page-header"> <h3><span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>{{ username }}<br><small>全部问答<span class="badge>"></span></small></h3> <ul class="list-group"> {% for foo in questions %} <li class="list-group-item"> <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span> <a href="#">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> <p style="..."> {{ foo.detail }}</p> </li> {% endfor %} </ul> </div> <div class="page-header"> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ username }}<br><small>全部评论<span class="badge"></span></small></h3> <ul class="list-group"> {% for foo in comments %} <li class="list-group-item"> <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span> <a href="#">{{ foo.author.username }}</a> <span class="badge">{{ foo.create_time }}</span> <p style="..."> {{ foo.detail }}</p> </li> {% endfor %} </ul> </div> <div class="page-header"> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ user }}<br><small>个人信息<span class="badge>"></span> </small> </h3> <ul class="list-group"> <li class="list-group-item">用户：{{ username }}</li> <li class="list-group-item">编号：{{ id }}</li> <li class="list-group-item">昵称：{{ nickname }}</li> </ul> </div> {% endblock %}
