Here is my setup:
class Product < ActiveRecord::Base
belongs_to :catalog
has_and_belongs_to_many :product_groups
end
class ProductGroup < ActiveRecord::Base
belongs_to :catalog
has_and_belongs_to_many :products
end
class Catalog < ActiveRecord::Base
has_many :product_groups
has_many :products, :through => :product_groups
end
I get:
Invalid source reflection macro :has_and_belongs_to_many for
has_many :products, :through => :product_groups. Use :source to
specify the source reflection.

I have seen a few threads with posts asking this question, but found
no suitable solution or workaround..
any ideas please.
