=head1 NAME

DBIx::Class::Helper::ResultSet::Errors - add exceptions to help when calling Result methods on an ResultSets

=head1 SYNOPSIS

 package MyApp::Schema::ResultSet::Foo;

 __PACKAGE__->load_components(qw{Helper::ResultSet::Errors});

 ...

 1;

And then in a script or something:

 my $col = $rs->id

 # dies with a helpful error!

=head1 DESCRIPTION

Users new to C<DBIx::Class> often make the mistake of treating ResultSets like
Results.  This helper ameliorates the situation by giving a helpful error when
the user calls methods for the result on the ResultSet.  See
L<DBIx::Class::Helper::ResultSet/NOTE> for a nice way to apply it to your entire
schema.
