I''m sure this exists somewhere but I cant figure out where I should be
looking after looking through the apis.
If I have a something like
class TodoItem < ActiveRecord::Base
belongs_to :assigned_to, { :foreign_key =>
''admin_user_id'',
:class_name => ''AdminUser'' }
end
and in a class method i have the symbol :assigned_to
how do i get information from it...
so it would work effectively like assigned_to.name
the class method in question is included in the TodoItem ( or any other
class for that matter )
as a mixin...

The Rails API page on ActiveRecord associations is here: http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html Basically, if you have an object called @todo, that belongs to @list you could reference it as: @todo.list # this is like calling List.find(list_id) Tom On 7/7/05, Sean T Allen <sean-5W9FBhQXBOtBDgjK7y7TUQ@public.gmane.org> wrote:> I''m sure this exists somewhere but I cant figure out where I should be > looking after looking through the apis. > > If I have a something like > > class TodoItem < ActiveRecord::Base > belongs_to :assigned_to, { :foreign_key => ''admin_user_id'', > :class_name => ''AdminUser'' } > end > > and in a class method i have the symbol :assigned_to > > how do i get information from it... > > so it would work effectively like assigned_to.name > > the class method in question is included in the TodoItem ( or any other > class for that matter ) > as a mixin... > > > > > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails > > > >
I understand that... I don''t have an object... its in a class method i want to be able to check out an association ( i have the symbol ) and call cget the table name and other inspect the association without having an object to be more clear: i have a class that is adding functionality ( as a mixin ) to models sometimes i need information on associated classes... make sense?
