django-tagconstants 0.1

Define constants in your settings, and make them available in your templates.

django-tagconstants

Define constants in your settings file, that are then made available in your templates.

Installation

From the command line:

pip install django-tagconstants

Add tagconstants to your installed apps:

INSTALLED_APPS = (
    ...
    'tagconstants',
    ...
)

Create a TAG_CONSTANTS dictionary in your settings.py file:

TAG_CONSTANTS = {}

Usage

For security purposes, tagconstants is designed so that you create a whitelist of variables to make available in your templates. For more information see the Design and Security section.

To use a constant in your templates, first add the constant to your TAG_CONSTANTS setting:

TAG_CONSTANTS = {
    'CONSTANT': 'SOME STRING',
}

Then in your templates, you can recall these constants with the {% constant ... %} template tag:

{% load tagconstants %}

{% constant "CONSTANT" %}
    {# renders to 'SOME STRING' #}

{% constant "CONSTANT" as "variable_name" %}
    {# loads the template variable variable_name="SOME STRING" #}
    {# into the template context #}
