Allow for silent or conditional loading of custom template tags

[anonymous]

In an effort to create a modular project I have included all custom tags / filters related to an app in that app's templatetags folder as instructed.

Should I ever want to use those tags in any general project templates (such as base templates or just any plain template which doesn't belong to that specific app) I must ensure that app is installed in the project settings. While I understand the need for the app to be installed for the tag to work I still want my project to remain modular and not break should I run {% load some_custom_tag_lib %} while the app is "turned-off".

It would be nice if there was some way to load the tag and use it silently (meaning it won't break if the app isn't loaded) or a way to condition the loading and usage of the tag if that app being installed while skipping it if the app isn't installed.

This is a good idea in theory, but without a practical suggestion (API, patch, etc.) there isn't much we can do to move it forward. Moving to "someday"; if someone comes up with a concrete proposal we can look at this again.

This would also help for the common requirement of loading {% static %} from staticfiles when it's available, from Django's default tags when it isn't.

I've implemented this a couple of years ago as django-friendly-tag-loader, ​PyPI / ​BitBucket

Wouldn't mind if it was included in Django. Is my approach acceptable?

Closing this, as discussed on #django-dev. Although useful in some cases it does not merit inclusion in Django core. For those who need it there is ​django-friendly-tag-loader.
