From 8f37ba81abbd13b935ce0f26574ff2b720b552f1 Mon Sep 17 00:00:00 2001 From: Aaron Patterson Date: Thu, 13 Jun 2013 15:36:25 -0700 Subject: This test does not test anything that happens in the real world. If you recreate the models without mucking with internal caches of the relation objects, then the test fails. For example: class Man < ActiveRecord::Base has_many :interests end class Interest < ActiveRecord::Base belongs_to :man end Then do this test: def test_validate_presence_of_parent_fails_without_inverse_of repair_validations(Interest) do Interest.validates_presence_of(:man) assert_no_difference ['Man.count', 'Interest.count'] do man = Man.create(:name => 'John', :interests_attributes => [{:topic=>'Cars'}, {:topic=>'Sports'}]) assert_not_predicate man.errors[:"interests.man"], :empty? end end end The test will fail. This is a bad test, so I am removing it. --- activerecord/lib/active_record/reflection.rb | 7 ------- activerecord/test/cases/nested_attributes_test.rb | 20 -------------------- 2 files changed, 27 deletions(-) diff --git a/activerecord/lib/active_record/reflection.rb b/activerecord/lib/active_record/reflection.rb index cfae2ffdb5..1335af9e39 100644 --- a/activerecord/lib/active_record/reflection.rb +++ b/activerecord/lib/active_record/reflection.rb @@ -310,13 +310,6 @@ module ActiveRecord @inverse_of ||= klass.reflect_on_association inverse_name end - # Clears the cached value of +@inverse_of+ on this object.
