#to_s ⇒ Object
Converts an SQL string and the name (typically assigned automatically by rails) into a Scout metric_name.
This prefers to use the ActiveRecord-provided name over parsing SQL as parsing is slower.
sql: SELECT “places”.* FROM “places” ORDER BY “places”.“position” ASC name: Place Load metric_name: Place/find
