How to replace frontend hardcoding with a configurable variable

Pick a name for the environment variable you want to configure cove with. In this example we use MY_ENV_VAR.

Edit cove_project/settings.py, and add a setting. The setting’s name typically matches the environment variable’s name. Set a default value, if appropriate. For example:

MY_ENV_VAR = os.getenv("MY_ENV_VAR", "default value")

Edit cove_project/context_processors.py, and add a mapping between the setting name, and what name you want use in the template: we’ve picked my_var.

def from_settings(request):
    return {
        'hotjar': settings.HOTJAR,
        ...
        'my_var': settings.MY_ENV_VAR,
    }

Edit a template, and use the variable, e.g.:

My var is: {{ my_var }}
{% if my_var > 5 %}Big{% endif %}
