为什么我会收到此错误 - 错误：在非对象上调用成员函数find（） - Cake 2.0

Question

Why do I get this error?

Fatal Error

Error: Call to a member function find() on a non-object
File: /home/mycake/public_html/app/Controller/TasksController.php
Line: 7

I think it has something to do with using CAKE 2.0 but I think the code in my controller might be CAKE 1.3? And I have done a bit of research but I don't know how to change the code to be in CAKE 2.0. Can anyone help?

This is the TasksController.php page

<?php
class TasksController extends AppController {
    public $name = 'tasks';
    public function index() {
        //THIS IS THE LINE 7
        $tasks = $this->Task->find('all');
        $this->set('tasks', $tasks);
    }
}

If you need any more info please ask because I'm not sure how else to make it more relevant to get an answer :)

Answer 1

CakePHP does auto instantiation of corresponding Model if the particular controller's property $uses is not set, so this means you might accidentally setting the property $uses of your AppController to either null or array().

So, check that if you have $uses in your AppController set to empty, or simply, in your TasksController, overwrite the value with public $uses = array('Task');.
