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!
