作业31-从首页问答标题到问答详情页

• 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)

• 首页标题的标签做带参数的链接。       {{ url_for('detail',question_id = foo.id) }}
• 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 }}

• 建立评论的对象关系映射：

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

•  尝试实现发布评论。

@app.route('/detail/<question_id>')
@loginfirst
def detail(question_id):
    quest=Question.query.filter(Question.id==question_id).first()

    context={
       'comments':Comment.query.order_by('-creat_time').all()

    }
    return render_template('detail.html',**context,ques=quest)

 

{% block main%}

<ul class="list-group" style="">

<!--<p>{{user}} quest</p>-->

    {% for foo in question %}

    <li class="list-group-item">

        <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>

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

        <p style="">{{foo.detail}}</p>

        <span class="glyphicon glyphicon-user" aria-hidden="true"></span>

        <a href="{{url_for('usercenter',user_id=foo.author_id)}}">{{foo.author.username}}评论:({{foo.comments|length}})</a>

        <span class="badge">{{foo.creat_time}}</span>

        <p style="color:black">内容</p>

    </li>

    {% endfor %}

</ul>

{% endblock %}
