Template context processor for delegating other context processors to individual apps. Useful if all views within an app require common context variables that aren't required by other apps.
Sometimes you have context variables that are needed on many pages in a site, but not all. You only want them to be evaluated when actually needed, especially if they are expensive calculations that do DB queries etc. The pattern to use is shown: put a callable into the context, not the final value, and also wrap the callable with memoize_nullary.
The above snippet makes all of the settings.py variables accessible in templates. Add this to the context_processors.py file inside your app directory. After that add the below line to the TEMPLATE_CONTEXT_PROCESSORS in your settings.py. '*app_name*.context_processors.access_to_settings'
