Is there a best practice to avoid Django's "Found another file with the destination path" during collectstatic on production?

Question

So I'm using Django 4.2, with Django-JET admin package via Django-jet-reboot fork; it enhances Admin with nice functionality and UX.

Each time I deploy my app on production, it feels its taking much longer when it reach collectstatic command cause it throws Found another file with the destination path warnings.

Now it seems it's related to Django-Jet's css & js files that needs to override django.contrib.admin ones, so my two questions are:

• Is this harmless and working as designed for my use-case? or there is a better practice to handle this?

  • (like specifically configuring not looking for those django files? or add them to local static folder?)

• Will adding additional UI-changing package(s) be ok with this?

  • For example I'm looking at creative tims' Black Dashboard Django - I just manage on it's priority in INSTALLED_APPS and let it be? = after jet so it doesn't override that package but takes the additional ones.

Got A response from Django Team: "This is working exactly as designed. This is precisely how you replace system-supplied static files with customized versions. It’s the same concept as overriding templates."

Incase someone thought the warnings means there's more to do (Sometimes it does; if you mistakenly duplicated finders on samefiles, so check findstatic first)
