Hi guys, I am stuck on, what i think is a class loader issue. In my app/models directory i have the following files: reductions/base.rb reductions/conversions_by_bucket.rb reductions/conversions_by_hour.rb reductions/impressions_by_hour.rb (background -- i am using mongoid, and i use these files to manage mapReduce) These classes only have class methods. In each of these classes I added the following method: def self.hello "hello" end And checkout this weirdness from the rails console:> Reductions::ImpressionsByHour.hello=> "hello"> Reductions::ConversionsByHour.hello=> "hello"> Reductions::ImpressionsByBucket.helloNoMethodError: undefined method `hello'' for Reductions::ImpressionsByBucket:Class BUT ...> require ''reductions/conversions_by_bucket.rb''=> nil> Reductions::ConversionsByBucket.hello=> "hello" Soooooo weird!!! So why is reductions/conversions_by_bucket.rb not being loaded by the class loader?! I am using rails 3.0.3 Thanks!! -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have the feeling the class-names are bit mismatched. what is the relation between Reductions::ConversionsByBucket and Reductions::ImpressionsByBucket ? - Kristian On Nov 23, 6:24 am, jonathan <jtush...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi guys, > > I am stuck on, what i think is a class loader issue. > > In my app/models directory i have the following files: > > reductions/base.rb > reductions/conversions_by_bucket.rb > reductions/conversions_by_hour.rb > reductions/impressions_by_hour.rb > > (background -- i am using mongoid, and i use these files to manage > mapReduce) > > These classes only have class methods.

Yeah I thought that too -- but i have looked it over hundreds of times
and can''t find the mismatch. I have simplifed the classes to just
have the hello method. And still have the same behavior. Here are
the three classes
#app/models/reductions/impressions_by_hour.rb
class Reductions::ImpressionsByHour
def self.hello
"hello"
end
end
#app/models/reductions/conversions_by_hour.rb
class Reductions::ConversionsByHour
def self.hello
"hello"
end
end
#app/models/reductions/conversions_by_bucket.rb
class Reductions::ConversionsByBucket
def self.hello
"hello"
end
end
ls app/models/reductions/
base.rb conversions_by_bucket.rb
conversions_by_hour.rb impressions_by_hour.rb unions.rb
The relationship between the classes is that they all perform map/
reduce methods. base.rb holds common code between them
I''m sure its something simple, but I am stumped!

I should add, that the class kind-of gets loaded, Checkout the following rails console sequence: [2] > Reductions::ConversionsByBucket => Reductions::ConversionsByBucket [3] > Reductions::ConversionsByBucket.class => Class [4] > Reductions::ConversionsByBucket.hello NoMethodError: undefined method `hello'' for Reductions::ConversionsByBucket:Class [5] > require ''reductions/conversions_by_bucket.rb'' => nil [6] > Reductions::ConversionsByBucket.hello => "hello" On Nov 23, 8:08 am, jonathan <jtush...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Yeah I thought that too -- but i have looked it over hundreds of times > and can''t find the mismatch.

Ok figured it out. The AWS/SW gem overwrites Module#const_missing -- and messes with things if you class ends in ''Bucket''. Man, that was a great use of 6 hrs. No idea why it only happens when coupled with InheritedResources, but that clearly is the root of the problem.
