this is my advise.

I add the following resources that may help in finding a solution.

I read all the guides that can be found by searching rails asset pipeline, but I will not link them all

My advice is to check the fingerprint of the application.css and application.js both with the Chrome Developer Tools (by going in any screen element, opening the developer toolbox with f12 and checking any style of any div or any js file). You will need to check which fingerprint version of the file is used, then open that version with the text editor and check what is loaded in the fingerprint version of the file.

If your file (for ex. user.js) is loaded at the bottom of the manifest, you should easily find it at the bottom of your fingerprinted application.js.

If you want to update this file you can run

rake assets:precompile

This will precompile assets only in development, for production you need to specify the environment. It will change that fingerprinted file application.css and application.js with the editing you have done.
