Am I correct in thinking that one cannot use attr_accessor in ActiveRecord models? I have success when using either cattr_accessor or mattr_accessor but not the native Ruby method. Am I missing something here, or is this how it really is? Thanks. Elliott G -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You _can_ use attr_accessor in ActiveRecord models. Like this:
class Article < ActiveRecord::Base
attr_accessor :my_prop
end
Maybe you could post some code and/or error message.

Hi Lasse. I think I may be able to get to the point a bit better with 2 more questions... Am I correct in thinking that attr_accessor always returns or sets an instance variable? Another reason I''m confused, is that, when I set an attr_accessor :foo in my model and then drop into script/console and call .methods on that model instance, I never see "foo" or "foo=" in the methods list when I run a search for them. Conversely when setting either cattr_accessor :foo or mattr_accessor :foo shows the the two new "foo" and "foo=" methods in the model''s method list as expected. What am I missing here?

Thats because mattr_accessor is at module level, cattr_accessor is at class level, and attr_accessor is at instance level. So you have to use class.instance_methods to find your method – like this: class_name.instance_methods.grep(/method_name/) /Lasse 2010/3/24 elliottg <x@simplecircle.net>> Hi Lasse. > > I think I may be able to get to the point a bit better with 2 more > questions... > > Am I correct in thinking that attr_accessor always returns or sets an > instance variable? > > Another reason I''m confused, is that, when I set an attr_accessor :foo > in my model and then drop into script/console and call .methods on > that model instance, I never see "foo" or "foo=" in the methods list > when I run a search for them.

That clearly explains some of the issues I was having. Thanks a ton!
