When I was using habtm product.categories.replace(..category objects) was working fine But when I started using has_many :through other relations are working, but I am not able to do product.categories.replace(..category objects) What is the solution then?

Hi Steve,
These are relationship declarations for product, category and
CategoriesProduct models!
class Product < ActiveRecord::Base
has_many :categories_products
has_many :categories, :through => :categories_products
class Category < ActiveRecord::Base
has_many :categories_products
has_many :products, :through => :categories_products
class CategoriesProduct < ActiveRecord::Base
belongs_to :category
belongs_to :product
end

You can roll your own though. Just delete the join model records of old ones not in the new set, then create join model records for the new ones not in the old set. And of course you should wrap that in a transaction. -- Josh Susser http://blog.hasmanythrough.com/ -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
