I have been trying to load some models for this website I am building. However, for an unknown reason, it will bring the following error :
An Error Was Encountered
Unable to locate the model you have specified: logon_model
Now , I have done my research. The problem would be that IC processes file names in lowercase. However, both my file and the file calling is in lower case, as shown here :
echo "VALIDATING";
// Validation passed. Off we go to account info verification from AA's database. God help us all.
$this->load->model('logon_model');
echo "FOUND MODEL";
$res = $this->logon_model->verify_user($this->input->post('username'),$this->input->post('password'));
echo $this->input->post('username');
echo $this->input->post('password');
The execution does not reach "FOUND MODEL", thus stops on the model loading. I have tried to use:
$this->load->model(site_url('logon_model'));
With no results. Need to mention the model file is correctly placed in the right model folder ?
How can I fix this ?
EDIT : Header for the model file :
class Logon_model extends CI_Model {
....

If you are on Linux then make sure your File name must match with the string passed in the load model methods the first argument.
$this->load->model('Order_Model','order_model');
You can use the second argument using that you can call methods from your model and it will work on Linux and windows as well
$result = $this->order_model->get_order_details($orderID);

You can give whatever name you want.
Styles guides are recommendations and not musts.
But you have to care to use everywhere the same name.
For example for Test_Model you have to:
class Test_Model extends CI_Model
Test_Model.php
$this->load->model('Test_Model');
$this->Test_Model
To avoid using hard coding strings you can load model like this:
$this->load->model(Test_Model::class);

Change your model file name, start with upper case letter like this: Logon_model.php
This happens when we migrate our project from windows server to LINUX server because linux is case sensitive while windows is not.
So, on windows even if don't write file name with upper case then also it will work fine but not on linux.

you must change your model name first letter capital. in localhost small letter work properly but online this not work. for exa:
common_model.php
replaced it to
Common_model.php

Changing the name of model name starting with Uppercase works. Example : Login_model.php instead of login_model.php

Adding to @jakentus answer, below is what worked for me:
Change the file name in the models package to Logon_model.php
(First letter upper case as @jakentus correctly said)
Change the class name as same as file name i.e.
class Logon_model extends CI_Model
Change the name in the load method too as
$this->load->model('Logon_model');
Hope this helps. Happy coding. :)

First letter of file name and class name must be in Uppercase.
Your model class will be
class Logon_model extends CI_Model
and the file name will be Logon_model.php
Access it from your contoller like
$this->load->model('Logon_model');

I experienced the same problem, but I fixed it by altering my application/config/routes.php file.
I made some restructuring to my controller directories and forget to effect it on the routes file.
Earlier:
$route['application/apply'] = 'ex/application/account/create';
and now:
$route['application/apply'] = 'application/account/create';

Here is what a model should look like: Make sure yours is like this.
<?php
class Logon_model extends CI_Model {
function __construct()
{
parent::__construct();
}
function myFunc()
{
// do something
}
}
note the upper-case class name.
To load it use:
$this->load->model('logon_model');
note all lower case.

In CodeIgniter 3.0-dev (get it from github) this is not working because the CI is search as first letter uppercase.
You can find the code on system/core/Loader.php line 282 or bellow:
$model = ucfirst(strtolower($model));
foreach ($this->_ci_model_paths as $mod_path)
{
if ( ! file_exists($mod_path.'models/'.$path.$model.'.php'))
{
continue;
}
require_once($mod_path.'models/'.$path.$model.'.php');
$CI->$name = new $model();
$this->_ci_models[] = $name;
return $this;
}
This mean that we need to create the file with the following name on application/models/Logon_mode.php

When creating models, you need to place the file in application/models/
and name the file in all lowercase - like logon_model.php
The logon_model.php
should contain the following:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Logon_model extends CI_Model
{
public function __construct()
{
parent::__construct();
}
...
Now, what you can do, to test if your application model is reachable, is to try opening it in the browser - like so:
http://example.org/application/models/logon_model.php
If you see the text No direct script access allowed it means you hit the right file (if you are in doubt, try writing something else in the exit() in the first line).
Secondly, for loading the model in your controllers, you should be able to do like this:
public function index()
{
$this->load->model('logon_model');
...
}
If everything above checks out as expected I would begin looking at file permissions and/or possibly symlinks if you are using any.

Models must be named and called with the first letter of the model name capitalized and the rest in lowercase.
For example: $this->load->model('Logon_model');
and:
class Logon_model extends CI_Model {
...
But you are correct about the file name.
