From 0ec967aa6655d62c92f72acb8d556a5b3f70762d Mon Sep 17 00:00:00 2001 From: Ryuta Kamizono Date: Mon, 7 Nov 2016 00:01:53 +0900 Subject: Respect new records for `CollectionProxy#uniq` Currently if `CollectionProxy` has more than one new record, `CollectionProxy#uniq` result is incorrect. And `CollectionProxy#uniq` was aliased to `distinct` in a1bb6c8b06db. But the `uniq` method and the `SELECT DISTINCT` method are different methods. The doc in `CollectionProxy` is for the `SELECT DISTINCT` method, not for the `uniq` method. Therefore, reverting the alias in `CollectionProxy` to fix the inconsistency and to have the both methods. --- .../associations/collection_association.rb | 7 ------- .../active_record/associations/collection_proxy.rb | 19 ++++++++++++++++--- 2 files changed, 16 insertions(+), 10 deletions(-) (limited to 'activerecord/lib/active_record') diff --git a/activerecord/lib/active_record/associations/collection_association.rb b/activerecord/lib/active_record/associations/collection_association.rb index f8aac895d7..7cd25ea524 100644 --- a/activerecord/lib/active_record/associations/collection_association.rb +++ b/activerecord/lib/active_record/associations/collection_association.rb @@ -246,13 +246,6 @@ module ActiveRecord end end - def distinct - seen = {} - load_target.find_all do |record| - seen[record.id] = true unless seen.key?(record.id) - end - end - # Replace this collection with +other_array+.
