Instance Method Details

#joins_left(*columns) ⇒ Object Also known as: join_left

Extends left_joins functionality to rails 4, and uses the same logic for rails 5.0.x and 5.1.x The default left_joins logic of rails 5.2.x is used. This results in and extra join in some cases. For example Post.joins(:comments).joins_left(comments: :author) will join the comments table twice, once inner and once left in 5.2, but only as inner in earlier versions.
