I am having a problem with a belongs_to and a has_one :through relation
which I found is a known bug in Ruby on Rails:
This ticket has 6 different attachments. Do I need all of them, or just
the latest one?
I can’t seem to find anywhere how one is supposed to deploy these
patches. Preferably I would patch something in my project that overrides
the installed rails stack as opposed to patching the installed rails
stack. How do I do this?
