Passing an object in every Django page

I have an object called Groups that is used in every single page on my website. However, Django only passes in Python objects to html through render_to_response and I can't render to response everytime something happens to the groups object.

How do I maintain this object(as in make it respond to adding and deletion) and produce it in every Django template that I have without calling render_to_response?

#tu_context_processor.py

from setting.models import Business


def include_business(request):
    business = Business.objects.all().last()
    return {'business': business}

in your settings file:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [TEMPLATE_DIR],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'core.tu_context_processor.include_business',
            ],
        },
    },
]

now a variable business will be available to you in all your templates tested in Django 4

write a template context processor:

#my_context_processors.py

def include_groups(request):
    #perform your logic to create your list of groups
    groups = []
    return {'groups':groups}

then add it in your settings file:

#settings.py

TEMPLATE_CONTEXT_PROCESSORS = (
     "django.core.context_processors.auth",
     "django.core.context_processors.debug",
     "django.core.context_processors.i18n",
     "django.core.context_processors.media",
     "path.to.my_context_processors.include_groups",
)

now a variable groups will be available to you in all your templates

You need to create template context processor to pass an object to each request. Here is some example

If you need data added to more than one template contexts you should look into achieving that via your own template context processor.
