Hi I have 2 tables with many to many rel and I received this error message:
I'm using Laravel 5.6 on a XAMPP stack.
Call to undefined relationship [categories] on model [App\Book].
Can anyone tell me please where's the problem?
It's my Category model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Category extends Model
{
public function Book (){
return $this->hasMany(Book::class);
}
}
And it's my Book model:
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Database\Eloquent\Model;
class Book extends Model
{
use Notifiable;
public $timestamps = false;
Protected $fillable =
['name','pages','price','description','ISBN','VIMG','published_at'];
public function user(){
return $this->belongsTo(user::class);
}
public function categories(){
return $this->belongsToMany(Category::class);
}
public function authors(){
return $this->belongsToMany(Author::class);
}
}
and it's my blade(show.blade.php):
