Question

我有两张桌子：

departamento（“地区”的西班牙语）
provincia（西班牙语“省”）

“departamento”有三个领域：

id_departamento
departamento（地区名称）
presidente（州长）

“provincia”有四个领域：

id_provincia
id_departamento（外键）
省（省名）
gobernador（州长）

我使用命令行（模型，控制器和模板）生成cakephp代码。

但是，在生成的视图中，显示插入输入ID，我不想要它 - ＆gt; SCREEN CAPTURE

当我要添加新省时，我想用区域名称显示和替换区域ID字段，如下拉列表

感谢您的帮助

如果您需要 departmento 的下拉列表，则需要使用find('list')并设置将其提取到模板中。

考虑到您的表名是Departmento，并且您希望填充值id_departamento和text departamento，请尝试以下操作：

/* Controller Code */
public function add()
{
    $provincium = $this->Provincia->newEntity();
    if ($this->request->is('post')) {
       /* Other code */
    }
    /* Modified code starts */
    $departmento = $this->Departmento->find('list', [
        'keyField'   => 'id_departamento',
        'valueField' => 'departmento'
    ]);
    $this->set(compact('departmento'));
    /* Modified code ends*/
    $this->set(compact('provincium'));
    $this->set('_serialize', ['provincium']);
}

/* Template code */

 echo $this->Form->select('id_departamento', $departmento, [
     'empty' => 'Departmento'
 ]);

如何在CAKEPHP 3的其他表格中显示下降列表中的数据？
