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。

2. @app.route('/detail/<question_id>')
   def detail(question_id):
       quest = 
       return render_template('detail.html', ques = quest)

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

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

{% block main %}
    <p>{{ username }} contextx</p>
    <ul class="new-list">
        {% for foo in questions %}
            <li class="list-group"
                style="padding-left: 0px; padding-right: 10px; box-shadow: rgba(0, 0, 0, 0.498039) 0px 0px 0px 0px;">
                <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span>
                <a href="#">{{ foo.author.username }}</a><br>
                <a href="{{ url_for('detail',questions_id=foo.id) }}">{{ foo.title }}</a>{#链接到相关详情页#}
                <span class="badge" >{{ foo.create_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
        {% endfor %}
    </ul>
{% endblock %}

1. 在详情页将数据的显示在恰当的位置。

2. {{ ques.title}}
   {{ ques.id  }}{{  ques.creat_time }}

   {{ ques.author.username }} 
   {{ ques.detail }}

{% extends'base.html' %}

{% block title %}问答详情{% endblock %}
{% block head %}
    <link rel="stylesheet" type="text/css" href="{{ url_for('static',filename='css/detail.css') }}">
{% endblock %}

{% block main %}
    <div class="page-header">
    <h3>题目：{{ questions.title }}<br><small>作者：{{ questions.author.username }} <span class="badge">发布时间：{{ questions.create_time }}</span></small></h3>
    </div>
    <p class="lead">详情：{{ questions.detail }}</p><br>

    {#发布评论#}
    <form action="{{ url_for('questions') }}" method="post">
        <div class="form-group">
            <textarea name="new_comment" class="form-control" rows="3" id="new-comment"
                      placeholder="请写下你的评论"></textarea>
            <input type="hidden" name="questions_id" value="{{ questions.id }}">
        </div>
        <button type="submit" class="btn btn-default" onclick="fnDetail">发送</button>

    {# 评论列表#}
    </form>
    <h4>评论({{ questions.comments|length }})</h4>
    <ul class="list-group" style="margin: 10px"></ul>
{% endblock %}
