Namespace Hell

I was writing a Rails plugin when I entered namespace hell. I had 2 classes with the same name and they were conflicting. I'm not sure if this was Rails problem or a simple ruby issue. Here is the scenario, the directory layout was as follows:

lib/query.rb
lib/warehouse/query.rb
lib/warehouse/table_report_query.rb

in query.rb I had:

class Query < ActiveRecord::Base
some_code_here
end

in lib/warehouse/query.rb I had:

module Warehouse
class Query
some_code_here
end
end


in lib/warehouse/table_report_query.rb I had:

module Warehouse
class TableReportQuery < Query
some_code_here
end
end

So, in the controller, when I did:

table_query = Warehouse::TableReportQuery.new()

You would think that TableReportQuery would inherit from Warehouse::Query. WRONG! It was inheriting from the first Query and throwing the classic activerecord "method not found" error.

So what's the solution. Well, I give credit to this blog article about Ruby Namespace Conflicts for inspiring my solution. I changed lib/warehouse/table_report_query.rb to be:

class Warehouse::TableReportQuery < Warehouse::Query
some_code_here
end

and it worked! Is that ruby Voodoo or what?
