php - CakePHP表关系$ belongs在添加操作中的下拉菜单中不显示任何记录

我有简单的关系表：每个表（协议）“ umowas”都有一个表（成人）“ rodzics”项，一个有表（儿童）“ dziecis”项。

当调用myaddress.com/cakephp/Umowas/add时，我看不到带有项目名称的项目“ rodzic_id”和“ dzieci_id”的下拉菜单。我只看到数字。

例如，“ rodzic_id”的下拉菜单显示Array（1 => 1，2 => 2，3 => 3），而不是其记录的名称，例如array（1 =>'Item name 1'，2 =>'项目名称2'）.....

Debug.log和Error.log为空。

我在屏幕底部的查询是：
     Nr Query Error Affected Num. rows Took (ms) 1 SELECT Rodzic . id FROM akademia-uat . rodzics AS Rodzic WHERE 1 = 1 2 2 3 2 SELECT Dzieci . id FROM akademia-uat . dziecis AS Dzieci WHERE 1 = 1 1 1 2

我的代码是：

<?php
class UmowasController extends AppController {
    var $name = 'Umowas';
    var $scaffold;
    var $helpers = array('Form' );

    function index() {
        $this->Umowa->recursive = 1;
        $umowas = $this->Umowa->find('all');
        $this->set('umowas', $umowas);
}
}
?>

<?php

class RodzicsController extends AppController {
    var $name = 'Rodzics';
    var $scaffold;

function index() {
    $this->Rodzic->recursive = 1;
    $rodzics = $this->Rodzic->find('all');
    $this->set('rodzics', $rodzics);
}
}
-------------------------------------------------------
<?php

class DziecisController extends AppController {
    var $name = 'Dziecis';
    var $scaffold;

function index() {
    $this->Dzieci->recursive = 1;
    $dziecis = $this->Dzieci->find('all');
    $this->set('dziecis', $dziecis);
}
}

<?php
    class Umowa extends AppModel {
        var $name = 'Umowa';



    public $belongsTo = array(
    'Rodzic' => array(
        'className'     => 'Rodzic',
        'conditions'    => '',
        'order'         => '',
        'foreignKey'    => 'rodzic_id' //or your external key
    ),
    'Dzieci' => array(
        'className'     => 'Dzieci',
        'conditions'    => '',
        'order'         => '',
        'foreignKey'    => 'dzieci_id' //or your external key
    )
);
 var $helpers = array('Form' );


 function add() {
        if (!empty($this->data)) {
            $this->Umowa->create();
            $this->Umowa->save($this->data);
            $this->redirect(array('action'=>'index'));
      }
        $rodzics = $this->Umowa->Rodzic->generateList();
        $this->set('rodzics', $rodzics);
        $dziecis = $this->Umowa->Dzieci->generateList();
        $this->set('dziecis', $dziecis);
    }
}
?>

<?php

class Rodzic extends AppModel
{
        var $name = 'Rodzic';
        var $hasMany = 'Umowa';
}
?>

-------------------------------------------------------
<?php

class Dzieci extends AppModel
{
        var $name = 'Dzieci';
        var $hasMany = 'Umowa';
}

view/Rodzics/add and do not exists
view/Umowas/add do not exists
view/Dziecis/add do not exist

我的表是这样的：

`
CREATE TABLE IF NOT EXISTS `dziecis` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `imie_dziecka` varchar(18) DEFAULT NULL,
  `nazwisko_dziecka` varchar(15) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;

CREATE TABLE IF NOT EXISTS `rodzics` (

最佳答案

我已将项目中的所有表格和名称翻译成英语。通过命令行蛋糕烘烤也完成了工作，所有表开始工作并显示字段。问题出在模型中，没有声明为公共$ displayField。
每个人每天都要做脚手架命令行工具并有英文名字，这很容易。而且，大多数importand是声明$ displayField并将其指向每个表中的title或name字段。
谢谢大家的支持。
