Ah, of course--thanks! I do want an instance method I think--want to call the generics from instance methods in the class. I will experiment.

Yes. In your module you've defined an instance method not a class method. But this: > class CarePhase < ActiveRecord::Base > include ModelHelper > > pretend_helper("hi!") Is the class trying to call the method, which fails because the class doesn't know about the 'pretend_helper' method. What you have would work fine if you did this: CarePhase.new.pretend_helper('hi') If you really do want a class method, try changing the method definition in PretendHelper to: def self.pretend_helper(msg) puts msg end And then you would be fine to call: CarePhase.pretend_helper('hi') Hope that helps. -- Josh http://iammrjoshua.com Roy Pardee wrote: > Ah yes--I see that thread now--thanks! > > I'm on an airplane & can't this minute check out the plugin Brandon > recommends, so I figured I'd try out the module approach you mention & > am having trouble. > > I've got a file /lib/model_helper.rb w/the following contents: > > module ModelHelper > def pretend_helper(msg) > puts(msg) > end > end > > And a model in care_phase.rb that starts out like: > > class CarePhase < ActiveRecord::Base > include ModelHelper > > pretend_helper("hi!") > > If I then open the console & type CarePhase.new I get this here: > > Loading development environment (Rails 2.0.2) > >> CarePhase.new > NoMethodError: undefined method `pretend_helper' for CarePhase(id: > integer, name: string):Class > from > c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/base.rb:1532:in > > `method_missing' > from C:/railsapps/collabtrac/app/models/care_phase.rb:9 > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:203:in > > `load_without_new_constant_marking' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:203:in > > `load_file' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:342:in > > `new_constants_in' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:202:in > > `load_file' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:94:in > > `require_or_load' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:248:in > > `load_missing_constant' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:453:in > > `const_missing' > from > c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:465:in > > `const_missing' > from (irb):1 > > > Can anybody say what I'm doing wrong? > > Thanks! > > -Roy -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
