CakePHP - 如何从控制器中的另一个模型中检索数据

Question

Currently i have 2 models. Users and Appbreak. They have associations of Users has many appbreak. Appbreaks belongs to users In my appbreak controller, there is a approve function which is called when a button from the view page is pressed.

In this function, i will need to update a value in the table of appbreak and a value in users table. I'm able to update value in appbreak by using the following:

$this->Appbreak->id = $id;
    $this->Appbreak->set('approve', 'Yes');
    $this->Appbreak->save();

However, i'm unable to pull the required data value from users table. <-- need to do so as i need to do some calculations before passing back the calculated value.

Am i able to get data from another model using the request method? Or do i need to use the find method? If i use the find method, am i able to update the the values and save it back into the database?

Answer 1

You can use any number of models in a controller . Declare the 'uses' array in controller

<?php
class DemoController extends AppController{
    public $uses=array('Appbreak','User');
}
?>

To get data from AppBreak model use find method of
$this->AppBreak object
Similarly to get data for User use find method of
$this->User object

Answer 2

Use find() to get your values, and if you need to update the values, use save(). Like so:

$this->Appbreak->Users->find('first', $params); 

(as described here )

To save, simply create an array with at least the relevant record id. Include any fields you want to update, and then call the save method on the array like so:

$data = array('id' => 10, 'title' => 'My new title');
// This will update Recipe with id 10
$this->Recipe->save($data);
