I’m a recent Ruby/rails initiate, coming from PHP. I’m working my way
through the Agile web development book, (slowly) and I ran into a wierd
bug where the method cart.empty! wasn’t being found when I tried to call
it after loading my cart from the session hash. Then I left it alone
for a while and now it works. ACK!
My question is, how does ruby/rails know what files to include so it can
find the class I’m instantiating? I’m used to having to include all my
files manually with php.
