Hi Jon,

Assuming you already uploaded the data to your database, you can do  
something like this to show it:

# Show a binary file

def download\_file  
@filedata = FileData.find(@params[:id])

```
  @response.headers['Pragma'] = ' '
  @response.headers['Cache-Control'] = ' '
  @response.headers['Content-type'] = @filedata.mime_type
  @response.headers['Accept-Ranges'] = 'bytes'
  @response.headers['Content-Length'] = @filedata.data.length
  @response.headers['Content-Transfer-Encoding'] = 'binary'
  @response.headers['Content-Description'] = 'File Transfer'
  # Remove the following comment if you want to force downloading

```

instead of viewing inline

# @response.headers[‘Content-Disposition’] = "attachment;

filename=#{@filedata.filename}"  
render\_text @filedata.data  
end

–  
Sincerely,

Frodo L.

</div>

instead of hand coding it, you can also use send\_data or send\_file:

## [ActionController::Streaming](http://api.rubyonrails.org/classes/ActionController/Streaming.html#M000073)
