Want to have a look @evgeni?

This looks like Ruby. I never understood how Ruby's ClassMethods and prepend and include and everything works.

#yolo?

[laugmanuel]

It's at least tested locally and it works. I needed a few tries myself. Prepending class methods is just magic...

[laugmanuel]

I'll also add a test for that later before merging..

Can you see if #29 also solves it?
No idea what's cleaner, poking around singleton_class or your prepended override.

Your solution also worked. I simplified it even more and added a test for it. This now looks like a good solution to me.

Interesting. I thought ClassMethods would be some magic name…

I'll go with this PR as we use the same here in git_templates: https://github.com/dm-drogeriemarkt/foreman_git_templates/blob/master/lib/foreman_git_templates/engine.rb#L34

Tests are passing and fix is verified locally - merging...
