mysql如何在cakephp中查询不同控制器的不同表

Question

I have 4 controllers and one database. Each controller is associated with one table. I am not able to query in one controller if i have to access table of another controller. I get "table not found" error.

Answer 1

You need to define the relations between the tables, using the associations:

http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html

By adding the right colums to your tables (Foreign ID fields) and defining the model associations, you will be able to access all the fields from the related tables.

Answer 2

Your question is a little confusing to say the least. Are you having issues accessing different models inside different controllers or is this an association issue? In your controller, you can define what models your controller uses by setting $uses:

class UsersController extends AppController {

    $uses = array('User', 'File');

    public function index(){
        $results = $this->File->find('all');
    }

}
