CodeIgniter不会在部署机器上加载模型

Question

I developed a small application with Codeigniter and brought it to run with vagrant and Debian. And everything was fine.

So now I'm trying to set up a virtual machine with Xubuntu 15.04. Installed the same packages (PHP as an Apache module)

Now I'm getting the following error:

Unable to locate the model you have specified: Person_model

This is how I load my model:

$this->load->model('person_model');

And this is how my model actually looks like in models/person_model.php

<?php

class Person_model extends CI_Model {
  function __construct() {
    parent::__construct();
  }

  // ...
}

On Xubuntu I'm running PHP 5.6.4-4ubuntu6.2 and on Debian I'm running PHP 5.4.41-0+deb7u1

Thanks for any advice and help!

Answer 1

Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers and models) must be named in a Ucfirst-like manner or in other words - they must start with a capital letter. http://www.codeigniter.com/user_guide/installation/upgrade_300.html#step-2-update-your-classes-file-names

This is CodeIgniter 3.0 coding convention which you must follow. So your model file should be models/Person_model.php.

Probably you use case insentive file system (host OS is like Windows or Mac) with Vagrant shared folder . And you don't use Vagrant shared folder with Xubuntu, don't you?

Anyway, this is problem with file system, not PHP version nor OS.
