There is such a structure:
There is a model book (Book) and model systems age restrictions (Rars). One book can be only one rars, but on one rars can refer a lot of books. That is, the relationship - one to many? The model Book:
class Book extends Model
{
public function rars()
{
return $this->belongsTo('App\Rars');
}
}
The model Rars:
class Rars extends Model
{
public function books()
{
return $this->hasMany('App\Book');
}
}
In migration Book:
$table->integer('rars_id');
$table->foreign('rars_id')->references('id')->on('rars');
Run code:
$book->rars()->save(\App\Rars::where('eternal_name', 'no_limits')->first());
(Rars with this eternal_name, guaranteed to exist)
And this return:
[BadMethodCallException]
Call to undefined method Illuminate\Database\Query\Builder::save()
What am I doing wrong?
According to the official documentation, for updating 'Belongs To' relationships you should use associate method. So i think this will work:
$book->rars()->associate(\App\Rars::where('eternal_name', 'no_limits')->first());
$book->save();
