  • 从首页问答标题到问答详情页

      1. 主PY文件写视图函数,带id参数。 
        @app.route('/detail/<question_id>')
        def detail(question_id):
            quest = 
            return render_template('detail.html', ques = quest)
      2. 首页标题的标签做带参数的链接。
              {{ url_for('detail',question_id = foo.id) }}

      3. 在详情页将数据的显示在恰当的位置。 
        {{ ques.title}}
        {{ ques.id  }}{{  ques.creat_time }}
        {{ ques.author.username }} 
        {{ ques.detail }}
      4. 建立评论的对象关系映射:

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

      5.  尝试实现发布评论。

    @app.route('/pinglun/<question_id>')
    def detial(question_id):
        quest=Question.query.filter(Question.id==question_id).first()
        return render_template('commentdetail.html',que=quest)
    <a href="{{ url_for('commentdetail',question_id=foo.id) }}">{{ foo.title}}</a>
    {% for foo in question %}
        <li class="list-group-item">
            <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
            <a href="{{ url_for('commentdetail',question_id=foo.id) }}">{{ foo.title}}</a>
            <p style="...">{{ foo.detail}}</p>
            <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
            <span class="badge">{{ foo.creat_time}}</span>
    
        </li>
     {% endfor %}
    class Question(db.Model):
        __tablename__ = 'comment'
        id =db.Column(db.Integer,primary_key=True,autoincrement=True)
        author_id=db.Column(db.Integer,db.ForeignKey('uesr.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'))
        author=db.relationship('User',backref=db.backref('comments'))
