Kohana 'Model not found' in Amazon EC2

Question

I've a Kohana 3.3 project working in a linux server and I moved it to Amazon EC2 linux instance.

It loads correctly all 'classes/Model/xxxxx.php' Models, but fails if model has no file definition (models that only resides in database), showing a 'Model not found' error.

Also I've some problems with model's properties, showing a 'The aaaaaa property does not exist in the Model_Bbbbbb class'

I am aware of PSR-0 implementation on Kohana >3.2

Model not found error:

ErrorException [ Fatal Error ]: Class 'Model_role' not found

Property error:

Kohana_Exception [ 0 ]: The team property does not exist in the Model_User class

These are my implementations:

/application/classes/Model/user.php

class Model_User extends Model_Auth_User
{
    public function rules()
        {
        …
        }
    protected $_has_many = array(
        'team' => array('through' => 'user_teams'),
    );
}

Database tables:

• roles
• users
• user_teams

Since this code is working on a previous linux server, I discarded PSR-0 problems, and I think this is a misconfiguration of Amazon Linux AMI.

Any idea?

Model not found error:

ErrorException [ Fatal Error ]: Class 'Model_role' not found

You need to have a PHP class for each model. It's possible it can be very simple, such as class Model_Role extends ORM {}, but it needs to exist and be placed in the right directory for autoloading.

Property error:

Kohana_Exception [ 0 ]: The team property does not exist in the Model_User class

probably you need to update the $_table_columns property in your Model_User to include the team field. The other possibility is your database doesn't have the team column in the users table.
