首页列表显示全部问答，完成问答详情页布局。

 

1. 首页列表显示全部问答：
   1. 将数据库查询结果传递到前端页面 Question.query.all()
   2. 前端页面循环显示整个列表。
   3. 问答排序

      {% extends 'base.html' %}

      py
      @app.route('/')
      def index():
          context = {
              'questions': Question.query.order_by('creat_time').all()
          }
          return render_template('index.html',**context)

   3. 以往评论列表显示区。

   4. html
      
          {% for foo in questions %}
              <li class="list-group-item">
                  <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
                  <a href="#">{{ foo.author.username}}</a>
                  <br>
                  <a href="#">{{ foo.title }}</a>
                  <span class="badge" >{{ foo.creat_time }}</span>
                  <p style=" text-indent: 18px">">{{ foo.detail }}</p>
      </li>
      {%  endfor %}

py

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