Question

I have a table a migration called plates .

$table->increments('id');
$table->integer('supplier_id')->unsigned();
$table->foreign('supplier_id')->references('id')->on('suppliers')->onDelete('cascade')->onUpdate('cascade');

And a model called Plates

 public function supplier()
{
    return $this->belongsTo('App\Models\Suppliers','supplier_id');
}

And a model Suppliers model

 public function plates()
        {
            return $this->hasOne('App\Models\Plates');
        }

when I check the relations with in the route doing this kind of thing.

 $storage = Suppliers::find(1);
   $att = $storage->plates;

   dd($att);

it just does not work. But the other way around works just fine. I am not sure what I am doing wrong. I have checked the docs and did countless other tries, but I can't understand it anymore.

Here is the error which keeps poping up.

Answer 1

You must add the parameter in the plates function at Supplier Model, you created the model in plural, Suppliers, so it tries to find a key suppliers_id

  public function plates()
  {
      return $this->hasOne('App\Models\Plates', 'supplier_id');
  }
