Controller

`

  public function show(Tickets $tickets)
    {
        //
        $tickets = Companies::with('tickets')->get();

        $severities = Severities::with('severity')->get();
        
        $ticketsinfos = Tickets::with('companies')->findOrFail(2);
    
        

  
     return view('customer.index', compact($tickets))->with(['tickets' => $tickets])->with(['severities' => $severities])->with(['ticketsinfos' => $ticketsinfos]);

    //dd($ticketsinfos->toArray());
        
    }
