[ACCEPTED]-In Ruby on Rails, to extend the String class, where should the code be put in?-ruby-on-rails-3
Accepted answer
I always add a core_ext directory in my lib dir.
Create 3 an initializer for loading the custom extensions (for 2 example: config/initializers/core_exts.rb). And add the following line in 1 it:
Dir[File.join(Rails.root, "lib", "core_ext", "*.rb")].each {|l| require l }
and have your extension like:
lib/core_ext/string.rb
class String
def capitalize_first
# ...
end
end
You could do it in config/initializers/string.rb
class String
def capitalize_first
# ...
end
end
should 1 be all you need (besides an app restart).
The guidelines in Rails 3.1 is the way to 3 go:

If you follow the default convention 2 you won't need to mess with an initializer 1 config.
