I have bellow one model has many other model. The question is when i update 2 models. One model is validate failed. The other model can not rollback.
Sample: class User < ActiveRecord::Base has_many :products, :dependent => :destroy validates_presence_of :name end class Product < ActiveRecord::Base belongs_to :user end # do a update User.transaction do user = User.find(1) p user.products # => [#product1,#product2] user.products = [#product3, #product4] user.name = "" user.save end => validate error: Name can't be blank But when you run bellow. user = User.find(1) p user.products # => [#product3,#product4] How can i resolve this problem? I don't need products are updated. I use .mysql innoDB .Rails 3.0.3 .activerecord (3.0.3) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
