[SOLVED] How to use template inheritance with Chameleon?

How to use template inheritance with Chameleon?

I am using latest Pyramid to build a web app. Somehow we have started using Chameleon as the template engine. I have used Mako before and it was extremely simple to create a base template. Is this possible with chameleon as well?

I have tried to look through the docs but I can not seem to find an easy solution.

Solution

With Chameleon >= 2.7.0 you can use the "load" TALES expression. Example:

main.pt:

<html>
<head>
    <div metal:define-slot="head"></div>
</head>
<body>
    <ul id="menu">
        <li><a href="">Item 1</a></li>
        <li><a href="">Item 2</a></li>
        <li><a href="">Item 3</a></li>
    </ul>
    <div metal:define-slot="content"></div>
</body>
</html>

my_view.pt:

<html metal:use-macro="load: main.pt">

<div metal:fill-slot="content">
    <p>Bonjour tout le monde.</p>
</div>

</html>
