從首頁問答標題到問答詳情頁

主PY文件寫視圖函數,帶id參數。 html

@app.route('/detail/<question_id>')
def detail(question_id):
    quest = 
    return render_template('detail.html', ques = quest)

 

 

@app.route('/detail/<question_id>')
def detail(question_id):
    quest=Question.query.filter(Question.id == question_id).first()
    return render_template("detail.html",ques=quest)

 

首頁標題的標籤作帶參數的連接。
      {{ url_for('detail',question_id = foo.id) }}python

<a href="{{ url_for('detail',question_id=a.id) }}">{{ a.question }}</a><br><br>

在詳情頁將數據的顯示在恰當的位置。 app

{{ ques.title}}
{{ ques.id  }}{{  ques.creat_time }}
{{ ques.author.username }} 
{{ ques.detail }}
{% extends 'index.html' %}
{% block title %}問答詳情{% endblock %}
{% block main %}
    <body style="url(../image/picture.jpg) no-repeat" >
         <div class="container">
            <div class="box">
                <h3 style="font-family:宋體;text-align: left;font-size: 40px">詳情頁</h3>
        </div>
             <div>
                 <h2>{{ ques.question }}<br><small>{{ ques.author.username }} <span class="badge">{{ ques.creat_time }}</span></small></h2></div>
             問題詳情:<p class="lead">{{ ques.questionDetail }}</p>
             <p class="location">評論</p>

        <hr>
        <form action="{{ url_for('question') }}" method="post">
            <div>
            <textarea class="form-control" id="new_comment" rows="6" placeholder="write your comment"style="height:200px;width:800px" ></textarea><br></div>
        <button type="submit" class="fabu"style="width:100px">發佈</button>
        </form>
        <ul class="list-group" style="margin: 10px"></ul>
        </div>

創建評論的對象關係映射:函數

class Comment(db.Model):
    __tablename__='comment'post

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'))
    time = db.Column(db.DateTime, default=datetime.now())
    detail = db.Column(db.Text, nullable=False)
    question = db.relationship('Question', backref=db.backref('comments'))
    author = db.relationship('User', backref=db.backref('comments'))
