                A django template tag that generates SVG icons. Useful to create svg favicons with emojis
              
          
    Usage

{% load utils_tags %}
{% svgicon '🕶️' 'rounded square' '#ffccff' as icon %}

                React-style components for Django templates, but only on Django Template. Simple, familiar, and good enough for most projects
              
          
    Why?

I built this because I wanted React's component patterns in Django templates without switching to a JavaScript frontend. When you use Jinja2 you have macros and that work similar. This will bring the Jinja2 macro experience.
No complex setup, no build process, just practical template components when you need them.
How It Works

Two template tags, that's it:

                TimestampStateField custom Django field that creates a timestamp-boolean pair
              
          
    The TimestampStateField creates two related fields in your Django models:

A timestamp field (DateTimeField) that records when a state changed
A corresponding boolean field that indicates the current state

The goal is to do state-tracking where you want to know both IF something is in a state and WHEN it entered that state. For example, tracking if a user is active and when they became active. And with that also gain the benefits of faster DB access and creating more efficient db indexes.
Here's how it works through an example:
