rspec

In Rails, when methods are declared on an association such as a has_many, these methods are not visible to the respond_to() rSpec method.

for example:

class Item < ActiveRecord::Base
has_many :translations do
    def active
        find(:first, :conditions => {:language_id, Language.active.id})
    end
end
end

it "should add an active method to the translations association" do
  @item.translations.should respond_to(:active)
end

^^ will never pass, however

it "should add an active method to the translations association" do
  @item.translations.respond_to?(:active).should be_true
end

^^ will pass
