Class 'App/Person' not found in index.blade.php - php

Question

I'm building a Laravel 5.6.27 application in PHP 7.2.5 where assignments can be created and given a task (task_id) and a person (person_id) to assign them to (along with dueDate, etc.). I'm getting this error when I try to load the page:
Class 'App/Person' not found (View: /Users/mmickelson/Sites/sacrament/resources/views/assignments/index.blade.php)
Here's the index.blade.php file:
#extends('layouts.master')
#section('title', 'Assignments')
#section('content')
<table>
#foreach($assignments as $assignment)
<tr>
<td>{{$assignment->person->firstName}}</td>
</tr>
#endforeach
</table>
#endsection
I'm showing only the firstName of the person to help make it as simple as possible and isolate the issue.
Here's the (beginning of) the AssignmentController.php:
use App\Assignment;
use App\Task;
use App\Person;
use Illuminate\Http\Request;
class AssignmentController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index() {
$assignments = Assignment::all();
return view('assignments.index', ['assignments'=>$assignments]);
}
...
Here's the (beginning of) the Assignment.php model:
namespace App;
use Carbon\Carbon;
use Collective\Html\Eloquent\FormAccessible;
use Illuminate\Database\Eloquent\Model;
class Assignment extends Model
{
use FormAccessible;
protected $fillable = ['person_id', 'task_id', 'dueDate', 'status', 'completedDate'];
public function person()
{
return $this->hasOne('App/Person');
}
...
The database table for "assignments" has a person_id column, as a foreign key to the "people" table.
If I remove person->name from index.blade.php, leaving the line as <td>{{$assignment}}</td>, the page loads fine but of course, shows the object. So, it seems to have something to do with accessing the Person associated with the Assignment.
Any ideas about what is causing the error?

Answer 1

I guess this issue because the name of class is wrong App/Person should be App\Person
and you can write it like the following:
public function person()
{
return $this->hasOne(\App\Person::class);
}

Answer 2

There is a minor mistake in your model:
public function person()
{
return $this->hasOne('App/Person');
}
Change the above code to below code:
public function person()
{
return $this->hasOne('App\Person');
}
it is better if you use the below code:
public function person()
{
return $this->hasOne(Person::class);
}
Person::class is same as App\Person.
