是否有用于同步更新项目的laravel功能或方法

Question

I have build my application with laravel (one to many relations table) ,and i want to synchronize two update functions .I mean when i update item in this function will update automatically in other function.

I already create the update functions and works well.What i need to do know is to synchronize the tow updates functions.

 $user= User::find($request->userid);
          $fiscal = Fiscal::find($request->fiscal_id);
          $contractuser->fiscal_id= $request->get('fiscal_id');
          $contractuser->contract_id= $request->get('contractid');
          $contractuser->save();
         return redirect()->route('contracts.show',$contractuser->user_id)->with('success','User Contract has been added successfully');

This is for contractuser

  public function update(Request $request, $id)
    {
        $fiscal=Fiscal::find($id);
        $fiscal->name=$request->get('name');
        $fiscal->year=$request->year;
        $fiscal->save();
        return redirect('fiscals');
    }

This is for fiscals

 public function update(Request $request, $id)
    {
        $contract=Contract::find($id);
        $contract->name=$request->get('name');
        $contract->save();
        return redirect('contracts');
    }

This is for contract.

The results are good but i want every time i change the fiscal or contract this change will be automatically on user contract .
