Models won't load

None of my models will load. No matter which one. I've tried different names, but I always get: "An Error Was Encountered

Unable to locate the model you have specified.” I'm at a loss.

/models/menu_model.php

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Menu_model extends CI_Model {
    
    function __construct() {
            parent::__construct();
    }
    
    function get_active_albums() {
        $query = $this->db->get_where('albums', array('is_active' = 1));
        
        return $query->result();
    }
} 


/controllers/welcome.php

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {
    
    public function __construct() {
        parent::__construct();
        $this->load->model('menu');
    }
    
    public function index() {
        $menu = $this->create_menu();
        $this->load->view('header');
        $this->load->view('welcome_message');
        $this->load->view('footer');
    }
    
    private function create_menu() {
        $data['query'] = $this->menu->get_active_albums();
        echo $data;
    }
} 


You named your model Menu_model so you need to load it as Menu_model not just Menu.

What did you Try? What did you Get? What did you Expect?

Just wondering, why are you including this line at the top of your model and controller?

PHP Code:

if ( ! defined('BASEPATH')) exit('No direct script access allowed'); 


Thanks!

Because he doesn't want that anyone who types domain.com/controllers/welcome.php in his browser will load the actual file behind that url.
It's a general CI convention if you look at the source code on the CI github repo.

Thanks! I didn't know.

You named your model Menu_model so you need to load it as Menu_model not just Menu.

I've tried that. When I do it that way, I just get a blank screen. I don't even get the error message.

Also, when I check my developer tools, I keep getting "Failed to load resource: the server responded with a status of 500 (Internal Server Error)"

Are you checking your server error log file?
The location of that file depends on the server used.
Apache (linux) is usually in /var/log/apache2.error.log

Also, change the model name (menu -> Menu_model) in ALL uses in your Welcome controller, I found two uses in the code posted above. The name is case sensitive on most OS's.

Okay, let me lay this out again. I'm developing on OpenShift by Red Hat. I've setup application just as the tutorial/walkthrough says to. I can't get models to load, and I keep getting a 500 error. I've checked the log files.

When I load the webpage I get this in the logs:

Code:

[08/Dec/2014:20:13:52 -0500] "GET / HTTP/1.1" 500 - "http://2scsb-aaronfenker.rhcloud.com/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.1.25 (KHTML, like Gecko) Version/8.0 Safari/600.1.25"

If the filename of my model includes "_model, “ the page gives the CI error message, but it still throws the 500 error. If I don't include "_model" in the filename, then the page doesn't load at all, but it still throws the 500 error.

When I do a git push I get the following errors:

Code:

[08/Dec/2014:20:11:04 -0500] "HEAD / HTTP/1.1" 500 - "-" "Ruby"
[08/Dec/2014:20:11:04 -0500] "HEAD / HTTP/1.1" 500 - "-" "Ruby"
[08/Dec/2014:20:11:04 -0500] "HEAD / HTTP/1.1" 500 - "-" "Ruby"
[08/Dec/2014:20:11:04 -0500] "HEAD / HTTP/1.1" 500 - "-" "Ruby"

I deleted my original app, and started fresh just in case I goofed on something in pushes. (Git is new to me too.)

Here's my code again.

controllers/welcome.php

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {

    /**

    }
    private function create_menu() {
        $data['query'] = $this->Nav_menu->get_active_albums();
        echo $data;
   }
} 


models/nav_menu.php

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Nav_menu extends CI_Model {
    function __construct() {
            parent::__construct();
    }
    
    function get_active_albums() {
        $query = $this->db->get_where('albums', array('is_active' = 1));
        
        return $query->result();
    }
} 


Is there a setting that I'm missing somewhere?

I guess you are using CI 2 so...

Try this in you controller - i just changed the model name to nav_m

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {
   
    public function index()
    {
        $this->load->model('nav_m');
        $this->load->view('header');
        $this->load->view('welcome_message');
        $this->load->view('footer');
    }
    private function create_menu() {
        $data['query'] = $this->nav_m->get_active_albums();
        echo $data;
   }
} 


And this in your model but don't forget to change the file name of the model in nav_m.php

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Nav_m extends CI_Model {
    function __construct() {
            parent::__construct();
    }
    
    function get_active_albums() {
        $query = $this->db->get_where('albums', array('is_active' = 1));
        
        return $query->result();
    }
}

Also set your methods in model to public.
