Question

I uploaded a CakePHP application on the production. It is working on my and my friend’s localhost. On the production I got the following error when trying to access different controllers:

Error: Call to a member function find() on a non-object
File: /app/Controller/GroupsController.php
Line: 10

<?php
class GroupsController extends AppController {

var $name = 'Groups';
var $displayField = 'name';
var $helpers = array('Paginator', 'Html', 'Form');

function index() {
    $groups = $this->Group->find('all');
    $members = $this->Group->GroupMember->find('all', array('order' => array('GroupMember.date_checked DESC'))); //Line 10!
    $owners = $this->Group->GroupContact->find('all', array('conditions' => array('GroupContact.owner' => 1)));
    $this->set(compact('groups', 'members', 'owners')); 
}

It looks like it fails to read GroupMember as an object.

Model – groupMember.php

<?php
class GroupMember extends AppModel{
var $name = 'GroupMember';
var $belongsTo = array(
    'Group' => array(
        'className' => 'Group',
        'foreignKey' => 'group_id'
    )
);
}
?>

Model – group.php

<?php
class Group extends AppModel{
var $name = 'Group';
var $hasMany = array(
    'GroupMember' => array(
        'className' => 'GroupMember',
        'foreignKey' => 'id',
    )
);
}
?>

You can see the errors on the http://www.thesupergroupproject.com/groups

Again – the project is working both on my localhost and my friend’s localhost. What could be causing the error?

Answer 1

Model names should be CamelCase. I suspect you are on windows or some other opperating system that is case insensitive, while your production is Linux which is case sensitive

Also when using 2.x there is no need for the $name property in models, this was for PHP4.x support which has been dropped.

Your relation with 'foreignKey' => 'id' seems to be incorrect, GroupMember should be related by the group_id field.
