Instance Method Details

#call(collection, direction, properties) ⇒ ActiveRecord::Relation

Applies a plain order clause to collection for a non-scope sort.

If field isn't a real column on the collection's model, the sort is logged and skipped instead of raising once the relation is evaluated.

Parameters:

  • collection (ActiveRecord::Relation) —

    the collection to sort

  • direction (Symbol) —

    the sort direction, :asc or :desc

  • properties (Hash) —

    the sort's properties, used to resolve :field

Returns:

  • (ActiveRecord::Relation) —

    the sorted collection, or collection unchanged if :field is unknown
