I’m looking at some open source apps on github, specifically the files in the /config folder like:
boot.rb, application.rb, etc.
They seem too complicated!
Is there a book that details all of this?
I’m finding the basics easy to understand, but configuration, setup is always a tricky part and a solid book on these topics would be great.
Agile Web Development With Rails is pretty much the gold standard. There are some other good resources listed in this SO thread.
