Laravel：从模型而不是控制器强制下载

I am using PHPExcel to generate an excel sheet and then output the file for download (force download). If I am to use the following from the controller file it works as expected:

return Response::download($file_path, 'myfile.xlsx');

But, I have to trigger this behavior from the Model and this does not seem to work.

Any suggestions?

You can call the response's send method:

Response::download($file_path, 'myfile.xlsx')->send();

But I would suggest against this. It is not your model's job to handle HTTP responses.
