A Django template tag for wrapping a template block in a reusable enclosing template
Project description
django-wrapwith
A Django template tag for wrapping a template block in a reusable enclosing template.
Provides a block tag called wrapwith which behaves exactly like the built-in include tag, but injects the contents of the block into the included template.
It is intended to make wrapper markup reusable, encouraging you to break your template into "components" which might have a particular enclosing structure but varying contents. It is particularly useful with design systems that provide components (cards, blockquotes, accordians etc) that have reusable structure but arbitrary content.
A toy example: imagine your design includes a box component which has a coloured border, but can contain any other markup inside it.
First, create a wrapper template, wrappers/box.html:
<div style="border: 1px solid {{ bordercol }}">
{{ wrapped }}
</div>
Note the special {{ wrapped }} variable, which will be replaced with your wrapped content.
Then, in your main page template:
{% load wrapwith %}
<html>
<body>
<h1>welcome to my page</h1>
{% wrapwith "wrappers/box.html" with bordercol="red" %}
<p>this is inside a red box</p>
{% endwrapwith %}
{% wrapwith "wrappers/box.html" with bordercol="green" %}
<p>this is inside a green box</p>
<p>and here's another paragraph inside the green box</p>
{% endwrapwith %}
</body>
</html>
Optional: aliasing templates
If you find writing out the full template path every time you use a component too verbose, you can define a dictionary of "aliases" in your Django settings, using the setting name WRAPWITH_TEMPLATES. This dictionary can be nested. You can then use a dotted path into this dictionary in your templates.
In your settings.py:
WRAPWITH_TEMPLATES = {
"wrappers": {
"box": "wrappers/box.html",
},
}
In your template:
{% wrapwith wrappers.box with bordercol="red" %}
<p>this is inside a red box</p>
{% endwrapwith %}
Tested on Python 3 with all currently supported Django versions.
