How to call model in Controller request $request - laravel

Question

I have a query in my model, which I want to call in my controller (request $request). It's working fine when the controller parameter is controller($id). But how to pass it in $request controller.
teacher Model with Query:
class teacher extends Model
{
public static function teacher($id)
{
return DB::table('teachers')
->leftjoin('religions', 'teachers.religion_id', '=', 'religions.id')
->leftjoin('areas', 'teachers.area_id', '=', 'areas.id')
->select('teachers.*','religions.*','areas.*')
->where('teachers.id',$id)
->first();
}
Controller which calls this model perfectly fine passing direct id:
public function report1($id)
{
$teacher = Teacher::teacher($id);
return View('teachers.report1' ,compact('teacher'));
}
Controller where I want to call it:
public function printreports(Request $request)
{
$teachers = $request->get('select2');
return view('teachers.report1',compact('teachers'));
}
Note: select2 contains teacher ids where I want to run model query.

Answer 1

Supposing you are have an array of ids in your select2 request param, probably easiest way is to change query at teacher model as follows:
use Illuminate\Support\Arr;
class teacher extends Model
{
public static function teacher($id)
{
return DB::table('teachers')
->leftjoin('religions', 'teachers.religion_id', '=', 'religions.id')
->leftjoin('areas', 'teachers.area_id', '=', 'areas.id')
->select('teachers.*','religions.*','areas.*')
->whereIn('teachers.id', Arr::wrap($id))
->get();
}
}
