首先修改原先的 book_list.html 的代码：
<!DOCTYPE html>

<!DOCTYPE html>

<link rel="stylesheet" href="/static/fontawesome/css/font-awesome.min.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
</head>
<!-- 以上 head 部分从 book_list.html 赋值过来并加以修改 -->
<!-- 以下 body 部分可从 Bootstrap 网站上找相关代码 -->
<body>
<div class="container">
<div class="row">
<div class="col-md-6 col-md-offset-3">
<div class="panel panel-primary">
<div class="panel-heading">添加书籍</div>
<div class="panel-body">
<form class="form-horizontal" action="/add_book/" method="post">
<div class="form-group">
<label for="book_title" class="col-sm-2 control-label">书名</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="book_title" name="book_title"
placeholder="书名">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
<div class="col-sm-10">
<select class="form-control" name="publisher">
{% for publisher in publisher_list %}
<option value="{{ publisher.id }}">{{ publisher.name }}</option>
{% endfor %}
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-success">提交</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
修改过程：
先写一个 container
找一个面板，在 Bootstrap 的组件中可找到
，并进行修改
现在需要一个 form 表单，在 Bootstrap 的全局 CSS 样式中找
复制下面的代码，替换面板代码中的 Panel content，并进行修改
先修改 email 处
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
修改为：
<div class="form-group">
<label for="book_title" class="col-sm-2 control-label">书名</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="book_title" name="book_title" placeholder="书名">
</div>
</div>
再来修改 password 处，这里需要用到下拉列表，还是去 Bootstrap 上找
在 “菜单” -> "被支持的控件" 处
，并进行修改
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
修改为：
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
<!-- 下拉列表 -->
<div class="col-sm-10">
<select class="form-control" name="publisher">
{% for publisher in publisher_list %}
<option value="{{ publisher.id }}">{{ publisher.name }}</option>
{% endfor %}
</select>
</div>
</div>
接着修改剩下的部分
最后在 form 表单处添加 action 和 method
运行效果：
编辑书籍：
最后修改 edit_book.html
<!DOCTYPE html>
<!-- saved from url=(0042)https://v3.bootcss.com/examples/dashboard/ -->
<html lang="zh-CN">

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<meta name="description" content="">
<meta name="author" content="">
<link rel="icon" href="https://v3.bootcss.com/favicon.ico" rel="external nofollow" rel="external nofollow" rel="external nofollow" >

<link rel="stylesheet" href="/static/fontawesome/css/font-awesome.min.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
</head>
<body>
<div class="container">
<div class="row">
<div class="col-md-6 col-md-offset-3">
<div class="panel panel-primary">
<div class="panel-heading">编辑书籍</div>
<div class="panel-body">
<form class="form-horizontal" action="/edit_book/" method="post">
<input type="text" style="display: none" name="id" value="{{ book_obj.id }}">
<div class="form-group">
<label for="book_title" class="col-sm-2 control-label">书名</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="book_title" name="book_title"
placeholder="书名" value="{{ book_obj.title }}">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">出版社</label>
<div class="col-sm-10">
<select class="form-control" name="publisher">
{% for publisher in publisher_list %}
{# 通过 if 条件判断来选择默认出版社 #}
{% if book_obj.publisher_id == publisher.id %}
{# 默认选择当前书籍关联的出版社 #}
<option selected value="{{ publisher.id }}">{{ publisher.name }}</option>
{% else %}
{# 其他的出版社不选中 #}
<option value="{{ publisher.id }}">{{ publisher.name }}</option>
{% endif %}
{% endfor %}
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-success">提交</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
修改过程：
首先把 add_book.html 复制过去，然后修改相关标题，把 “添加书籍” 改为 “编辑书籍”
然后在 form 表单下一行添加一个有书籍 id 的 input 标签
然后在书名的那个 input 处添加一个 value
然后将下拉列表的出版社选择改为原 edit_book.html 的
