如何定义“全局”在CakePHP中找到模型的条件？ [英] How to define "global" find conditions for model in CakePHP?

问题描述

是否可以定义在所有使用特定模型的控制器和函数中始终有效的查找条件？

Is it possible to define find conditions that are always effective in all controllers and functions that use specific model?

例如，如果我想只返回在股票无论什么。也许在模型中的某个地方：

For example if I want to return only products that are in stock no matter what. Maybe somewhere in model:

conditions => array('inStock >' => 0)

推荐答案

我想你可以尝试在模型上做一个函数，然后在控制器中用一个简单的线路调用它。

I think you could try to do a function on the model, and then call it in controller with a simple line.

控制器：

$productsInStock = $this->Product->getProductsInStock();

型号：

function getProductsInStock() {  
            $produtcsInStock = $this->find('all', array('conditions' => array('inStock >' => 0)));
            return $productsInStock;          
}

Or try this Link, I think it will help. I just don't know nothing about callbacks: http://book.cakephp.org/view/1049/beforeFind
