- 显示所有评论
{% for foo in ques.comments %} - 所有评论排序
uquestion = db.relationship(‘Question‘, backref=db.backref(‘comments‘, order_by=creat_time.desc)) - 显示评论条数
{{ ques.comments|length }}
@app.route(‘/usercenter/<user_id>‘) @log def usercenter(user_id): user=User.query.filter(User.id==user_id).first() context={ ‘username‘:user.username, ‘questions‘:user.questions, ‘comments‘:user.comments } return render_template(‘usercenter.html‘,**context)
- 完成个人中心
<h4>评论：({{ ques.comments|length }})</h4><br> <ul class="list1"> {% for foo in ques.comments %} <li class="list2"> <img style="width: 30px" src="{{ url_for(‘static‘,filename=‘../static/images/friends.jpg‘) }}" > <a href="{{ url_for(‘all‘,user_id=foo.author_id) }}">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span><br> <p class="pinglun">评论:{{ foo.detail }}</p><br> </li> {% endfor %} </ul>
1.个人中心的页面布局（html文件及相应的样式文件）
