pra*_*432 1 django list django-templates
我有一个Django模板,我认为我的if语句有一些语法错误.`
<head>
<link rel="stylesheet" type="text/css" href="/static/css/styles.css" />
<Meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<h1>Testing the class page</h1>
<div id = "bookResults">
<ul>
{% if books %}
{% for book in books %}
<li>
<div class="bookDisplay">
<div>
<text class= "text" id = "bookTitle">{{ book.title|safe }}</text><br/>
<text class= "text" id= "bookAuthor">by {{ book.author|safe }}</text><br/>
<text class = "test" id = "bookDetails">
ISBN: {{ book.isbn|safe }}
Bookstore Price: {{ book.price }}
</text><br/>
<img src= "{{ book.imageURL }}" class = "bookImage" />
</div>
</div>
</li>
{% endfor %}
{% else %}
<h2>Sorry, no books or classes were found- can you try searching again?"</h2>
{% endif %}
</ul>
</div>
</body>
</html>`
我基本上试图说 - 如果书籍(列表)有价值然后做下面的一切,如果没有,做其他事情 - 我已经尝试{{if books | length> 0}}但是没有果
如果工作,我该怎么做？
谢谢
这段代码没有错.你也可以像这样写:
<ul>
{% for book in books %}
<li>...</li>
{% empty %}
<h2>Sorry, no books</h2>
{% endfor %}
</ul>
如果它无法正常工作,那么您将错误的上下文传递给模板.
