I just realized that a lot of the relationships are camelCased, and they should be underscore_cased. Please update before I pull this in.

Paul..Do we have to change the class names too ? cos, I guess while declaring a variable it should follow the similar conventions except that it is pluralized or un pluralized ?how will rails detect otherwise which class is in the relation ship?Correct me if iam wrong

[paulnsorensen]

The class names are always camel cased, but everything within the class is not. You should follow the pluralized conventions, rails will be able to detect it. For instance, you could have a class like this

class Car < ActiveRecord::Base
  has_many :model_types
  belongs_to :auto_manufacturer
end

class ModelType < ActiveRecord::Base
  belongs_to :car
end

class AutoManufacturer < ActiveRecord::Base
  has_many :cars
end
