1. 首页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

py文件：

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

首页html:

{% extends\'myweb.html\' %}
{% block indextitle %}首页{% endblock %}




{% block indexhead %}
    <link rel="stylesheet" type="text/css" href="../static/css/component.css"/>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    <script src="../static/js/login.js"></script>
{% endblock %}

{% block indexbody %}
    <div class="container">
        <div class="row clearfix">
            <div class="col-md-4 column">
                <div class="jumbotron well">
                    <h1>
                        Hello, world!
                    </h1>
                    <p>
                        This is a template for a simple marketing or informational website. It includes a large callout
                        called the hero unit and three supporting pieces of content. Use it as a starting point to
                        create something more unique.

                    </p>
                </div>
            </div>
            <div class="col-md-8 column" style="background: whitesmoke">

                <ul>
                    {% for foo in questions %}
                        <li>
                            <a href="#">{{ foo.author.username }}</a>
                            <br>
                            <a href="{{ url_for(\'detail\',question_id=foo.id) }}">{{ foo.title }}</a>
                            <br>
                            <p>内容：{{ foo.detail }}</p>
                            <span>评论数: 100000++++</span>
                            <span class="badge pull-right">{{ foo.create_time }}</span>
                            <hr>
                        </li>
                    {% endfor %}
                </ul>
            </div>
        </div>
