I have a problem with the datamapper on codeigniter, i would like to delete all the records from 3 tables with the relation. Something like:

        $c = new Camp();

        $c->where('id', $this->input->post('id'))->get();



        $cf = new CF();

        $cf->where('camp_id', $this->input->post('id'))->get();



        $p = new Pro();

        $p->where('camp_id', $this->input->post('id'))->get();



        $c->delete(array($cf, $p->all));

This give me a problem, but if i do individually, adding a delete or delete_all after the where:

        $c = new Camp();

        $c->where('id', $this->input->post('id'))->get();

        $c->delete();



        $cf = new CF();

        $cf->where('camp_id', $this->input->post('id'))->get();

        $cf->delete();



        $p = new Pro();

        $p->where('camp_id', $this->input->post('id'))->get();

        $p->delete_all();

it not delete the records from the table, it just put as null the field camp_id where is more than a record, in this case, in the p->delete_all, and i would like to delete from the table. I could do with codeigniter, but i must do with the datamapper. Someone know how to do it?

Thanks.
