cakephp：如何访问另一个模型，它没有关联 [英] cakephp: how to access another model, which has no association

问题描述

我有3个表：
项目，设施和 project_

I've 3 tables: project, amenities and project_amenities.

我只添加项目表单，我想添加新的设施，首先添加到设施表，然后project_amenities表。

I add project form only, i want to add new amenities, which first added to amenities table and then project_amenities table.

所以我定义了这些关系：

So I defined these relations:

Project hasMany Facilities

Amenity属于项目

c $ c> projects_controller ：
var $ uses = array（'Amenity'）;

I declared in projects_controller: var $uses = array('Amenity');

这里给我添加操作的错误

This gives error for my add action here

if (!empty($this->data)){

    $this->Project->create();

为

Notice (8): Undefined property: ProjectsController::$Project 
[APP\controllers\projects_controller.php, line 60]

编辑
此外，我不能：

edit Also, I cannot do:

$this->Amenity->create();
$insertData = array('name' => $this->data['Project']['Amenity'][$i]['name']);
$this->Amenity->save($insertData);

推荐答案

我建议您使用 $ this-> loadModel（'ModelName'）; 。然后你可以使用下面的模型

I would like to suggest you to use $this->loadModel('ModelName'); in the function where you needed. Then you can use the model as below

$this->ModelName->function();

使用 $ uses 到整个控制器。这会影响您的效果。

By using $uses array it make available to entire controller. Which will affect your performance.
