1. 顯示所有評論
   {% 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">發布於  {{ foo.create_time }}</span>
          </li>
    
   
          <hr>
   {% endfor %}
      </ul>

2. 所有評論排序
   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‘))

3. 顯示評論條數
   {{ ques.comments|length }}

   <a href="#" class="post_item_foot">評論：({{ foo.comments|length }})</a>

4. 完成個人中心

1.個人中心的頁面布局（html文件及相應的樣式文件）

2.定義視圖函數def usercenter(user_id):

3.向前端頁面傳遞參數

4.頁面顯示相應數據

發布的全部問答

發布的全部評論

個人信息

@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)
