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

py文件：

@app.route(\'/\')
def moban():
    context = {
        \'wenda\': Wenda.query.order_by(\'creat_time\').all()
    }
    return render_template(\'moban.html\',**context)

html文件：

<ul class="news-list">
        {% for foo in wenda %}
        <li class="list-group-item">
            <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
            <a href="#">{{ foo.author.username}}</a>
            <br>
            <a href="{{ url_for(\'detail\',wenda_id= foo.id) }}">{{ foo.title }}</a>
            <br>
            <span class="badge" >{{ foo.creat_time }}</span>
            <p style="background-color: aqua">{{ foo.detail }}</p>
        </li>
        {%  endfor %}

    </ul>

 

 

2、完成问答详情页布局：

1. 包含问答的全部信息
2. 评论区
3. 以往评论列表显示区。

 1 {% extends \'moban.html\' %}
 2 {% block title %}详情界面{% endblock %}
 3 {% block head %}
 4     <link rel="stylesheet" href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css">
 5     <script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script>
 6     <script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script>
 7 {% endblock %}
 8 {% block body %}
 9     <div class="col-md-2 column "></div>
10     <div class="col-md-8 column ">
11         <ul class="list-unstyled">
12             <li>
13                 <h2 href="#" class="text-center">{{ www.title }}</h2>
14                 <br>
15                 <p class="text-center">
16                     <a href="#">
17                         <small>{{ www.author.username }}</small>
18                     </a>&nbsp&nbsp&nbsp
19                     <span class="pull-center"><small>{{ www.creat_time }}</small></span>
20                 </p>
21                 <p>{{ www.detail }}</p>
22                 <form>
23                     <div class="form-group">
24                     <textarea name="comment" class="form-control" rows="6" id="comment"
25                               placeholder="请输入评论"></textarea>
26                     </div>
27                     <button type="submit" class="btn btn-default">发送</button>
28                 </form>
29             </li>
30         </ul>
31     </div>
32     <div class="col-md-2 column "></div>
33 {% endblock %}

 

 

3、在首页点击问答标题，链接到相应详情页。

 

1 @app.route(\'/detail?<wenda_id>\')
2 def detail(wenda_id):
3     wen = Wenda.query.filter(Wenda.id == wenda_id).first()
4     return render_template(\'detail.html\',www=wen)
