From 5aab0c053832ded70a3a4b58cb97f8f8bba796ba Mon Sep 17 00:00:00 2001 From: Brian Thomas Storti Date: Sat, 23 Nov 2013 09:24:52 -0200 Subject: Raise `RecordNotDestroyed` when children can't be replaced Fixes #12812 Raise `ActiveRecord::RecordNotDestroyed` when a child marked with `dependent: destroy` can't be destroyed. The following code: ```ruby class Post < ActiveRecord::Base has_many :comments, dependent: :destroy end class Comment < ActiveRecord::Base before_destroy do return false end end post = Post.create!(comments: [Comment.create!]) post.comments = [Comment.create!] ```` would result in a `post` with two `comments`. With this commit, the same code would raise a `RecordNotDestroyed` exception, keeping the `post` with the same `comment`. --- .../test/cases/associations/has_many_associations_test.rb | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'activerecord/test/cases') diff --git a/activerecord/test/cases/associations/has_many_associations_test.rb b/activerecord/test/cases/associations/has_many_associations_test.rb index a025d49fa3..45bc974025 100644 --- a/activerecord/test/cases/associations/has_many_associations_test.rb +++ b/activerecord/test/cases/associations/has_many_associations_test.rb @@ -1770,4 +1770,15 @@ class HasManyAssociationsTest < ActiveRecord::TestCase assert_equal [bulb1], car.bulbs assert_equal [bulb1, bulb2], car.all_bulbs.sort_by(&:id) end + + test "raises RecordNotDestroyed when replaced child can't be destroyed" do + car = Car.create! + original_child = FailedBulb.create!(car: car) + + assert_raise(ActiveRecord::RecordNotDestroyed) do + car.failed_bulbs = [FailedBulb.create!] + end + + assert_equal [original_child], car.reload.failed_bulbs + end end -- cgit v1.2.3
