How to use 'having' with paginate on relationship's column in laravel 5

Question

I need to grab the vehicles whose relation \'dealer\' is having distance < 200

Vehicle::join(\'dealers\', \'vehicles.dealer_id\', \'=\', \'dealers.id\')
          


        

Answer 1

having and havingRaw doesn't have access to generated fields in the query see this example from laravel docs

Your query will have to lookk like this

Vehicle::join('dealers', 'vehicles.dealer_id', '=', 'dealers.id')
            ->select(DB::raw("dealers.id, ( cos( radians(latitude) ) * cos( radians( longitude ) ) ) AS distance"))
            ->havingRaw('(cos(radians(latitude)) * cos(radians(longitude))) < 200');
