That is not quite what Ian suggested.  Scalar assignment (i.e. $rs =3D)
provides scalar context to the right-hand side, so you're calling all() in
scalar context, so you get the number of elements.  Also, the assignment to
$rs is misleading, as you're not actually assigning a ResultSet object to
it, but rather the result of calling ->all() on a ResultSet.

Try one of these approaches instead, which all do the same thing in slightly
different ways.  Ian's original suggestion:

@arr =3D $c->model('DB::data)->search({},{result_class
=3D> 'DBIx::Class::ResultClass::HashRefInflator',});
  entity =3D> \@arr

or, with an anonymous array instead of a temporary array variable:

  entity =3D> [$c->model('DB::data)->search({},{result_class
=3D> 'DBIx::Class::ResultClass::HashRefInflator',})]

or, assigning the ResultSet to $rs first:

$rs =3D $c->model('DB::data)->search({},{result_class
=3D> 'DBIx::Class::ResultClass::HashRefInflator',});
  entity =3D> [$rs->all],
