I'm newbie for grocery crud. I have a simple database for accounting of insurance policies. In the main table (dogovor) I keep the insurance contract. This table is linked to another, that contains insurance policies under the contract (dogovor_persons). A contract can have multiple policies. How can I display on the edit form of an insurance contract list of related policies?

Now I can see a list of contracts (dogovor). I can get a list of policies with the selection the current contract. I can edit a contract using standard functions. How can I display a list of policies (polises_by_dogovor) in the edit form of the insurance contract (dogovor table)?

public function dogovor()
{
    $crud = new grocery_CRUD();

    $crud->set_table('dogovor');
    $crud->set_subject('dogovor');
    $crud->set_relation('country','countries','country');
    $crud->set_relation('program','programs','name');
    $crud->set_relation('agent','users','login');
    // .....other standart items
    $crud->columns('id','created','Person','dateofbirth','country');

    $crud->fields('id','Person','dateofbirth','program','tarif','country','created','edited_by');

    //in this place I call the function to add the policy with the selection of an insurance contract
    $crud->add_action('add policie', 'http://www.grocerycrud.com/assets/uploads/general/smiley.png', 'calc/polises_by_dogovor');

    $crud->callback_before_insert(array($this,'set_created_date'));//ставим дату создания перед  добавлением нового договора

    $output = $crud->render();

    $this->_example_output($output);

}


public function polises_by_dogovor($did)
{
    try{
        $crud = new grocery_CRUD();

        $crud->set_table('dogovor_persons');           
        $crud->required_fields('fio');
        $crud->columns('born','passport_serie','passport_no');
        $crud->where('did',$did);

        $crud->callback_field('did',array($this,'insert_dogovor_ID')); //set parent ID

        $output = $crud->render();

        $this->_example_output($output);

    }catch(Exception $e){
        show_error($e->getMessage().' --- '.$e->getTraceAsString());
    }
}



function insert_dogovor_ID($value = '', $primary_key = null)  //set parent ID
{

    return '<input type="text" maxlength="11" value="'.$this->uri->segment(3).'" name="did" style="width:462px">';
