Constructor Details

.new(klass, params, unmatched = nil) ⇒ DocumentNotFound

Create the new error.

Examples:

Create the error.

DocumentNotFound.new(Person, ["1", "2"])

Create the error with attributes instead of ids

DocumentNotFound.new(Person, :ssn => "1234", :name => "Helen")

Parameters:

  • klass (Class) —

    The model class.

  • params (Hash | Array | Object) —

    The attributes or ids.

  • unmatched (Array | Hash) (defaults to: nil) —

    The unmatched ids, if appropriate. If there is a shard key this will be a hash.
