CakePHP call a member function on a non-object

Question

I have the following Model and Controller files, and when I find this url http://....../pois/index, I get this error:

Notice (8): Undefined property: PoisController::$Poi [APP/controllers/pois_controller.php, line 5]

Fatal error: Call to a member function find() on a non-object in /home/joecoyle/public_html/app/controllers/pois_controller.php on line 5

This model is called poi.php:

<?php
class Poi extends AppModel {

}
?>

And the controller is called pois_controller.php

<?php
class PoisController extends AppController {

    function index(){
            $this->set('pois',$this->Poi->find('all'));
    }
}
?>

Since I'm new to CakePHP, I'm not sure what causes this error, since everything seems to be called right, and I follow the guide on the CakePHP site ...

thank

/ : Cake :

app/config/inflections.php $irregularPlural :

$irregularPlural = array('poi'=>'pois');

"Pois" "Poi".

, / . , , Cake "" "". $this->News->find, $this->New->find, .

Answer 4

This is a problem because it was $this->Poinot initialized as an object. I am not familiar with CakePHP, but in your init function in PoisController or in contructor you have to call $this->Poi = new Poi();, so when you try to call the find()method in the index action, it will be called on an instance of the Poi model.
