I am not sure what is causing this. As mentioned I am getting the same error from different classes and no where do I have a custom macro method. I have reset the server a few times, but I still get the same thing. The code running on the live server works fine. Although I have made some changes, none of them are related to data access. Any ideas? ==== One of the cases is happening on the following call: game\_dates = GameDate.find( :all, :conditions =\> “season\_id = #{self.id}”, :include =\> [{:bookings =\> :location}]) NoMethodError (undefined method `macro' for #): /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/attribute_methods.rb:256:in`method\_missing’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/association\_preload.rb:40:in `preload_one_association' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/association_preload.rb:38:in`each’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/association\_preload.rb:38:in `preload_one_association' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/association_preload.rb:17:in`preload\_associations’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/association\_preload.rb:21:in `preload_associations' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/association_preload.rb:19:in`each’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/association\_preload.rb:19:in `preload_associations' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/association_preload.rb:16:in`preload\_associations’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/association\_preload.rb:16:in `each' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/association_preload.rb:16:in`preload\_associations’ /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active\_record/base.rb:1343:in `find_every' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.0/lib/active_record/base.rb:536:in`find’ /app/models/season.rb:54:in `create\_games’ ---

There is already a method group\_by in rails, you’ve overwritten it with one which different meaning rails: \>\> [1,2,3,‘Foo’, ‘Boo’].group\_by {|r| r.class} =\> [[Fixnum, [1, 2, 3]], [String, [“Foo”, “Boo”]]] you: [1,2,3,‘Foo’, ‘Boo’].group\_by {|r| r.class} =\> {“Boo”=\>[String], 1=\>[Fixnum], 2=\>[Fixnum], “Foo”=\>[String], 3=\>[Fixnum]} which doesn’t seem to be doing anything useful, at least not in the way rails uses it Fred ---

These are the methods I added to lib/array.rb. class Array def group groups = {} self.each do |item| groups[item] ||= [] groups[item] \<\< item end groups end def group\_by(&block) groups = {} self.each do |item| val = yield(item) groups[item] ||= [] groups[item] \<\< val end groups end end ---
