A set of tools to help simplify your Django templates

$ pip install django-template-simplify

Then add the app into INSTALLED_APPS in settings.py

INSTALLED_APPS = [
    ...,
    'template_simplify',
]

dom_id

dom_id is a helper method that returns a unique DOM ID based on the object's class name and primary key.

{% load template_simplify %}

{% dom_id instance %}               ->  task_1
{% dom_id instance 'detail' %}      ->  detail_task_1
{% dom_id Task %}                   ->  new_task

1. dom_id first argument can be string, instance or Model class
2. dom_id second argument is optional string that will be used as prefix.

You can also use it in your Django view code.

from template_simplify import dom_id

target = dom_id(instance, "detail_container")

We can say goodbye to id="task-{{ task.pk }}" and use id="{% dom_id task %}" instead.

The benefit is, it simplified the DOM ID generation in Python and Django template, and avoid typo error in many cases.

class_names

Inspired by JS classnames and Rails class_names

class_names can help conditionally render css classes

{% load template_simplify %}

<div class="{% class_names test1=True 'test2' ring-slate-900/5=True already-sign-in=request.user.is_authenticated %}"></div>

'<div class="test1 test2 ring-slate-900/5 dark:bg-slate-800 %}"></div>'

It can work well with TailwindCSS's some special char such as / and :

Below is an example of if else

<div class="{% class_names active=request.user.is_authenticated inactive=!request.user.is_authenticated %}"></div>

1. Please note ! can be used just like Javascript.
2. So if user is not authenticated in this case, we would get <div class="inactive"></div>

This can help make css logic more organized.
