Problem with Sth3Model loading from Sth2Model when Sth3Model is in subdiretory (Subdir1)

[nowackipawel]

Inside Models directory I've got:

• Sth1Model
• Sth2Model
• Subdir1
  • Sth3Model

inside one method of Sth2Model I'm creating Sth3Model
$st3 = new \Subdir1\Sth3Model();

after update my project to the newest version (commit: a5b6d93) one problem appears:

Error Class 'Subdir1\Sth3Model' not found

in that line from Sth1Model:

$sthSth = new \Subdir1\Sth3Model();

Hmm. I think there was only one change in that commit that might have affected this, but it was fixing an existing bug in the FileLocater algorithm, I believe.

How are your model's namespaced, and your namespace defined within Config/Autoload? Or are they not namespaced at all?

It looks to me like the call should be: $st3 = new \App\Models\Subdir1\Sth3Model.

Ofc I tried also sth like \App\Models... so I had to changed my code.
Anyway I created Subdir1 again with class AbcModel

` namespace Subdir1;
class AbcModel extends \CodeIgniter\Model
{

protected $table = 't_abc';

protected $primaryKey = 'abc_id';

public function __construct() {
    parent::__construct();
    return $this;
}

} `

and from other class which is 1 level up (root of models directory) i tried to create AbcModel()

new \App\Models\Subdir1\Abc();

but it ended with the same exception.

There is nth special in Autoload:

`
$psr4 = [
'Config' => APPPATH.'Config',
APP_NAMESPACE => APPPATH, // For custom namespace
'App' => APPPATH, // To ensure filters, etc still found
];

	$classmap = [
	    'PHPMailer' => APPPATH . 'ThirdParty/vendor/phpmailer/phpmailer/class.phpmailer.php'
    ];

`

The namespace of the AbcModel class is wrong. It should be App\Models\Subdir1.

[nowackipawel]

Yeah, sorry for that, but I'm sure it was working in that way before cause I've got copy with previous code where namespace was only Subdir1 . Sth has been changed from previous version.

[lonnieezell]

Did the previous version actually have a namespace defined in the class? It's possible that it might have worked without a namespace, though I honestly haven't tried that in a while. With a namespace though, it's not possible for it to work that way.

[nowackipawel]

Real code:

root@p:/home/pi# cat backup/application/Models/Admin/UserLoginModel.php 
<?php
namespace Admin;

class UserLoginModel extends \CodeIgniter\Model
`
```

[lonnieezell]

What you're showing there should not work. With a namespace of Admin and a class name of UserLoginModel, and no separate Admin namespace created, it would look for the file at /Admin/UserLoginModel.

Don't know what to tell you other than that's simply how namespacing and the PSR4 autoloading work. There's no magic $this->load->model method anymore, it's simply new SomeModel() so the rules are pretty simple. The only possible other way is if there was no namespace on the class at all, then it would look for files in the "legacy" CI3 folders of Application/Controllers, Application/Libraries, and Application/Models.
