Hi,  
I want to send file in the response,  
I found it’s possible with render method:  
def get\_file  
render :file =\> path, :content\_type =\> “application/x-unknown”  
end.

But there is one problem,  
the default name of that file in system dialog is the method name.

Is it possible to set default file name?

…ever look into the FileUtils / File classes?

The file name is the last path step of the url… so put a complete url  
for that download in routes and map it to your get\_file action…  
something like:

map.connect ‘/something/myfilename.xxx’,  
:controller =\> ‘mycontroller’, :action =\> ‘get\_file’

Note that you may also need to set the Content-Disposition header to  
Attachment to get a file save dialog on some browsers… depending on  
the content-type I suppose.
