From 8fb0de2cae8e6f26c71ab8e4267d3841a38a29b9 Mon Sep 17 00:00:00 2001 From: Paul Nikitochkin Date: Sun, 14 Jul 2013 17:32:56 +0300 Subject: Removed where_values_hash from AR::NullRelation In order to build associated records for owners which has not been saved need to get where values to use as default attributes. But for new record owner uses `ActiveRecord::NullRelation` which override `where_values_hash` to return empty hash stub. `where_values_hash` is not used to invoke any sql query, but good to build others chains (even will be never executed) like: ```ruby post = Post.new admin_comment = post.admin_comments.build assert_equal 'Admin', admin_comment.author ``` Closes #11376, #11676, #11675 --- .../associations/has_many_associations_test.rb | 23 ++++++++++++++++++++++ activerecord/test/cases/relations_test.rb | 4 ++++ 2 files changed, 27 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 064e31f634..caa916346a 100644 --- a/activerecord/test/cases/associations/has_many_associations_test.rb +++ b/activerecord/test/cases/associations/has_many_associations_test.rb @@ -80,6 +80,13 @@ class HasManyAssociationsTest < ActiveRecord::TestCase assert_equal 'exotic', bulb.name end + def test_build_from_association_should_respect_scope + author = Author.new + + post = author.thinking_posts.build + assert_equal 'So I was thinking', post.title + end + def test_create_from_association_with_nil_values_should_work car = Car.create(:name => 'honda') @@ -1629,6 +1636,22 @@ class HasManyAssociationsTest < ActiveRecord::TestCase assert_equal car.id, bulb.attributes_after_initialize['car_id'] end + def test_attributes_are_set_when_initialized_from_has_many_null_relationship + car = Car.new name: 'honda' + bulb = car.bulbs.where(name: 'headlight').first_or_initialize + assert_equal 'headlight', bulb.name + end + + def test_attributes_are_set_when_initialized_from_polymorphic_has_many_null_relationship + post = Post.new title: 'title', body: 'bar' + tag = Tag.create!(name: 'foo') + + tagging = post.taggings.where(tag: tag).first_or_initialize + + assert_equal tag.id, tagging.tag_id + assert_equal 'Post', tagging.taggable_type + end + def test_replace car = Car.create(:name => 'honda') bulb1 = car.bulbs.create diff --git a/activerecord/test/cases/relations_test.rb b/activerecord/test/cases/relations_test.rb index 88a12c61df..9e5ffa0cce 100644 --- a/activerecord/test/cases/relations_test.rb +++ b/activerecord/test/cases/relations_test.rb @@ -300,6 +300,10 @@ class RelationTest < ActiveRecord::TestCase assert_equal({}, Developer.none.where_values_hash) end + def test_null_relation_where_values_hash + assert_equal({ 'salary' => 100_000 }, Developer.none.where(salary: 100_000).where_values_hash) + end + def test_joins_with_nil_argument assert_nothing_raised { DependentFirm.joins(nil).first } end -- cgit v1.2.3
