Ruby on Rails 6.0.6

Since v6.0.6

Available in: v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

implicit_order_column=(column_name)

Sets the column to sort records by when no explicit order clause is used during an ordered finder call. Useful when the primary key is not an auto-incrementing integer, for example when it’s a UUID. Note that using a non-unique column can result in non-deterministic results.
