问题
I have a module called user_searches. It performs some searches that aren't core to the user model, thus, why I'm putting the responsibility somewhere else. I want to organize all my models like this that perform non-core user functions in a lib subfolder called user. Right now to include the module's methods in the User model I have to put...
require 'user/user_searches'
class User < ActiveRecord::Base
include UserSearches
end
...I don't need the require if the file is directly in the lib folder, but do if it's in the subfolder. What do I have to do so I don't need the require?
回答1:
You could put the necessary require lines into lib/user.rb that way, all requirements are loaded recursively on application launch.
Alternatively, you could put something like this into an initializer:
# put into config/initializers/load_lib.rb
Dir["#{RAILS_ROOT}/lib/**/*.rb"].each { |f| require(f) }
It will require all ruby files in your lib folder. You just have to make sure if this is really what you want :)
回答2:
This is works that cause
in file rails-2.2.2/lib/initializer.rb in method default_load_paths initialized to load path just the lib folder without subdirectories, to solve this you can edit your project ` environment.rb config file and push into config.load_path array all subdirs.
