PHP warning: include(C:\xampp\htdocs\hse\vendor\composer/../../app/Buildings.php): failed to open stream

Question

I've previously manually deleted some models files in App* and created other with just removing the "s" symbol as because laravel by default can recognise the models from there name , and models by Laravel standadrd must be written normal not in plural.

Before deleting the models that i created them using php artisan make:model Buildings -m

The new model i created after i removed the (buildings) model is php artisan make:model Building Notice that i just created a new model without 's'

Now in my User model i have created method :

public function UserAssignedBuilding(){
        return $this->hasManyThrough('App\Building','App\Area','user_id','area_id');
    }

Building.php Model file

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Building extends Model
{
    protected $table = 'buildings';

    public function areas(){
        $this->belongsTo('App\Area');
    }

}

Area.php Model file:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Area extends Model
{
    protected $fillable = [
        'name'
    ];

    public function users(){
        return $this->belongsToMany('App\User','area_user','area_id','user_id');
    }

    public function buildings(){
        return $this->hasMany('App\Building');
    }
}

In php artisan when i run the following command, to get the user assigned buildings:

>>> User::find(4)->UserAssignedBuilding
PHP warning:  include(C:\xampp\htdocs\hse\vendor\composer/../../app/Buildings.php): failed to open stream: No such file or directory in C:\xampp\htdocs\hse\vendor\composer\ClassLoader.php on line 444

It seems that the error is the framework trying to load the (Buildings.php) model file, which i had already delete it and created (Building.php) instead .

I run the following :

C:\xampp\htdocs\hse>composer dumpautoload
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Package manifest generated successfully.

But issue not fixed

Also tried to get buildings rows, other error showing:-

>>> Building::all()
PHP Fatal error:  Class 'Building' not found in eval()'d code on line 1

Answer 1

The error is showing in Tinker (php artisan tinker) , When i dumped the composer autoload file

composer dump-autoload

Then tried again in tinker , the same error is showing like the composer dump command did not do it work, but when i close the current tinker and open new one (php artisan tinker) , every thing now work perfectly .

So , the solution in brief is when you run the dumpautoload command, you need to restart the tinker to see the changes.

Answer 2

In your command you are missing model namespace

It should be

App\User::find(4)->UserAssignedBuilding

And

App\Building::all()

Also change method UserAssignedBuilding to buildings
