If I put a controller class into a gem, and then require that gem in
my application, will the controller then be available to handle
I'm designing a controller that I think could be useful for more than
one project, so I was thinking I would develop it separately and
create a gem for my main project to use. However, I don't know much
about gems yet, so I'm not sure if this would work.
Well it can be done from a plugin, you just need to add the folder
containing your models to $LOAD_PATH, Dependencies.load_paths and
config.controller_paths (where config is the object in the initializer
block in environment.rb). My controller wasn't rendering any views
(just json) but If you were you'd probably need to fiddle around with
view paths. With any luck you'll be able to massage this into working
with a gem too.
