Laravel - 缺少[路线：编辑] [URI：cruds / {agency} / {id} / edit]所需的参数

I've a problem with route and parameters, in particular I'm trying to pass two variables. I've to edit a point {idPost} in an agency {idAgency}. My controller is

public function change($agency,$id)
{
    $crud = Description::find($id);
    $impl = Implementation::find($id);
    return view('cruds.edit',compact('crud','impl','id'));
}

called in view as

<a href="{{ action('CrudsController@change',$agency['id'],$post['id']) }}">
  <button id="modifica" class="btn btn-danger" type="submit"><i class="fa fa-pencil fa-lg">&nbsp;&nbsp;</i>Modifica</button>
</a>

and my route is

Route::get('cruds/{agency}/{id}/edit',['as'=>'edit','uses'=>'CrudsController@change']);

I've looked for solution a lot before to ask but I haven't found anything good for me. I'm sorry. Thanks a lot in advance.

You should try this:

Please change your Anchor tag

<a href="{{ url('cruds',[$agency['id'],$post['id']]) }}">
  <button id="modifica" class="btn btn-danger" type="submit"><i class="fa fa-pencil fa-lg">&nbsp;&nbsp;</i>Modifica</button>
</a>
