(3) Somehow explicitly refer to my Image model using some foolproof
reference system. Perhaps some Module or default namespace that a
Rails application's models are all in? Basically: is there any way at
all to refer to my Image model without relying upon it to be in Ruby's
top-level symbol table?
Seems like I ran into something like this before. Will
image = ::Image.find(params[:id])
work? Seems like it should.
