}

Answer 1

You have to select the primary key to retrieve the necessary results.

Deal::with(array('deal_category'=>function($query){
                $query->select('id', 'name as dealcategory');
            }))->get()

Use facade DB . You can try something like this:

DB::table('deal as d')
    ->join('deal_category as dc', 'd.id', '=', 'dc.deal_id')
    ->select('d.name as dealname', 'dc.categoryname')
    ->get();
