Django custom template tag which accepts a boolean parameter

I came up against this problem a while ago, and arrived at the conclusion that using 1 and 0 was the simplest solution.

However an idea might be to add a context processor which adds True and False to the template context using respective names:

# projectname/appname/context_processors.py

def booleans():
    return {
        'True': True,
        'False': False,
    }

Then obviously you would need to add that context processor in your Django settings file:

TEMPLATE_CONTEXT_PROCESSORS += {
    'projectname.appname.context_processors.booleans',
}
