                return redirect()->back()->withInput();
                $pd->full_name = $request->full_name;
                $pd->organisation = $request->rganisation;
                $pd->position_grade = $request->position_grade;
            }
        }

        // redirect somewhere after
        if($patrols){
            return redirect()->route('patrol.index')
                ->with('successs' , 'created successfully');
        }
        return back()->withInput()->with('errors', 'Error creating  Details');

    }
