Rails Triple Join

I have 3 models Report, Server, and Platform. I need to execute a query that involves triple joining all 3 models and making the query based on that. But I get the following error whenever I try to triple join

ActiveRecord::ConfigurationError: Association named 'platform' was not found; perhaps you misspelled it?

Here are my models

Report

class Report < ActiveRecord::Base

 belongs_to :server

 delegate :company_id, :to => :server

    class << self

        def method(url, base_url)
            Report.joins(:server).joins(:platform).where(:platforms => {:company_id => 5}).all
        end
    end

end

Server

class Server < ActiveRecord::Base

 has_many :reports
 belongs_to :platform

end

Platform

class Platform < ActiveRecord::Base

 attr_accessible :company_id

 has_many :servers

end

Try this: (note the s in platform it is needed because the table names are plural):

Report.joins(:server => :platform).where(:platforms => {:company_id => 5}).all
