从Atong中的节点读取mongoose中的数据

Question

我正在建立一个带有node和mongoose in atom的库的网页。我已经创建了一个登录表单，注册并添加了一本书＃34;。现在在主页上我想看到所有书籍，我不知道要做到这一点。我知道它与双{{}}或三{{{}}}括号有关，但我不确定。我稍后将以更漂亮的形式提出，现在我只想看看我如何打印，例如标题。顺便说一句，我使用了车把视图引擎。

<h2 class="page-header">Cartile existente</h2>
<h4>In curand!</h4> // <- there I'm supposed to put the book titles.

<h2 class="page-header">Adauga o carte noua</h2>//this is the "add a book" 
{{#if errors}}
      {{#each errors}}
        <div class="alert alert-danger">{{msg}}</div>
      {{/each}}
{{/if}}
<form method="post" action="/booksImp/addbook">
   <div class="form-group">
    <label>Numar Inventar</label>
    <input type="text" class="form-control" placeholder="Numar curent" name="nrinv">
  </div>
  <div class="form-group">
