Question

Job Model

class Job_Model extends Model
{
    protected $table = "tbljobs";
    protected $primaryKey = "JobID";
    public $timestamps = false;

    public function OrderType()
    {
        return $this->hasOne('\App\Models\OrderType_Model', "OrderTypeID");
    }
}

Order Type Model

class OrderType_Model extends Model
{
    protected $table = "tblOrderType";
    protected $primaryKey = "OrderTypeID";
    public $timestamps = false;
}

Query

$Jobs = \App\Models\Job_Model::with("OrderType")->get();

I am retrieving all records from tbljobs table. but each record is not showing associated record from Order Type Table.

Am I missing something ?

dd() result

Answer 1

You need has() and with() . Has returns only jobs with order types and with actually injects the order type into each job.

 $Jobs = \App\Models\Job_Model::has("OrderType")->with("OrderType")->get();

Edit: if your foreign key is actually in the Jobs table, not the Order type table, you want a belongs to relationship.

hasOne() assumes the foreign key is in the other table.

belongsTo() assumes the foreign key is in this table.

Answer 2

I suppose your question is just how you could see dumped data on the screen? Try it like this

$Jobs = \App\Models\Job_Model::with("OrderType")->get();

foreach ($Jobs as $job) {
    var_dump($job->toArray());
}
