From 1b4399dfe7eaa8dd2a75f35815ea429962c51a29 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafael=20Mendon=C3=A7a=20Fran=C3=A7a?= Date: Tue, 7 Jul 2015 13:38:54 -0300 Subject: Fix regression caused by a01d164b When preload is used in a default scope the preload_values were returning nested arrays and causing the preloader to fail because it doesn't know how to deal with nested arrays. So before calling preload! we need to splat the arguments. This is not needed to includes because it flatten its arguments. --- activerecord/test/cases/relations_test.rb | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'activerecord/test/cases') diff --git a/activerecord/test/cases/relations_test.rb b/activerecord/test/cases/relations_test.rb index acbf85d398..5f48c2b40f 100644 --- a/activerecord/test/cases/relations_test.rb +++ b/activerecord/test/cases/relations_test.rb @@ -647,6 +647,25 @@ class RelationTest < ActiveRecord::TestCase end end + def test_preloading_with_associations_default_scopes_and_merges + post = Post.create! title: 'Uhuu', body: 'body' + reader = Reader.create! post_id: post.id, person_id: 1 + + post_rel = PostWithPreloadDefaultScope.preload(:readers).joins(:readers).where(title: 'Uhuu') + result_post = PostWithPreloadDefaultScope.all.merge(post_rel).to_a.first + + assert_no_queries do + assert_equal [reader], result_post.readers.to_a + end + + post_rel = PostWithIncludesDefaultScope.includes(:readers).where(title: 'Uhuu') + result_post = PostWithIncludesDefaultScope.all.merge(post_rel).to_a.first + + assert_no_queries do + assert_equal [reader], result_post.readers.to_a + end + end + def test_loading_with_one_association posts = Post.preload(:comments) post = posts.find { |p| p.id == 1 } -- cgit v1.2.3
