问题 So I'd like to share models between two Rails apps and do not like the submodules solution (burned me in the past). I'm thinking about using gems to solve this and have this basically working: Create a gem using jeweler (my_models) Create a rails app with something in the Gemfile like: gem 'my_models', :path => '../my_models' so you can avoid constantly packaging the gem, etc. Use shotgun to constantly reload all the classes (otherwise you can't really edit my_models files without restarting

问题 Could I simply copy the devise app and lib (and gem?) folders into my respective project folders and have them work just as if I was using the gem? I'd like to do this so that I can really see all the code, possibly do some customization, and also avoid some "cannot find" errors in my IDE. Is this a bad idea?
