From 681a0a0299500024635e790c1ceb2da281652444 Mon Sep 17 00:00:00 2001 From: Ryuta Kamizono Date: Mon, 13 Jun 2016 01:04:33 +0900 Subject: Fix `calculate` with a string value in `from` and eager loading `construct_relation_for_association_calculations` pass a string value to `construct_join_dependency` when setting a string value in `from`. It should not pass a string value, but always `joins_values`. Related #14834, #19452. Fixes #24193. --- activerecord/lib/active_record/relation/finder_methods.rb | 10 +--------- activerecord/test/cases/associations/eager_test.rb | 4 ++++ 2 files changed, 5 insertions(+), 9 deletions(-) (limited to 'activerecord') diff --git a/activerecord/lib/active_record/relation/finder_methods.rb b/activerecord/lib/active_record/relation/finder_methods.rb index 87eea8277a..882605de31 100644 --- a/activerecord/lib/active_record/relation/finder_methods.rb +++ b/activerecord/lib/active_record/relation/finder_methods.rb @@ -398,15 +398,7 @@ module ActiveRecord end def construct_relation_for_association_calculations - from = arel.froms.first - if Arel::Table === from - apply_join_dependency(self, construct_join_dependency(joins_values)) - else - # FIXME: as far as I can tell, `from` will always be an Arel::Table. - # There are no tests that test this branch, but presumably it's - # possible for `from` to be a list? - apply_join_dependency(self, construct_join_dependency(from)) - end + apply_join_dependency(self, construct_join_dependency(joins_values)) end def apply_join_dependency(relation, join_dependency) diff --git a/activerecord/test/cases/associations/eager_test.rb b/activerecord/test/cases/associations/eager_test.rb index f7bb3e54d5..80d9a6083b 100644 --- a/activerecord/test/cases/associations/eager_test.rb +++ b/activerecord/test/cases/associations/eager_test.rb @@ -90,6 +90,10 @@ class EagerAssociationTest < ActiveRecord::TestCase assert_no_queries { authors.map(&:post) } end + def test_calculate_with_string_in_from_and_eager_loading + assert_equal 10, Post.from("authors, posts").eager_load(:comments).where("posts.author_id = authors.id").count + end + def test_with_two_tables_in_from_without_getting_double_quoted posts = Post.select("posts.*").from("authors, posts").eager_load(:comments).where("posts.author_id = authors.id").order("posts.id").to_a assert_equal 2, posts.first.comments.size -- cgit v1.2.3
