how to download a file from application resources

Question

What i need is the ability to download a file which is not stored in the database but in one of application folders. lets say that the path of this file might look like this:

application_name/log/important_resources/file.txt

In my app I want one place where this file can be downloaded. I tried

File.open(path)

but it fails to give me anything, literally just open the file and does nothing.

EDIT

Where i need this feature is one of the models

You can create download action and use send_file as Slicedpan suggest in your controller. — urjit on rails, Apr 18 '14 at 11:23

You can use send_file in your controller action to send files to the client. documentation

you can't use this function from a model, can you explain why you can't use it from a controller? – Slicedpan Apr 18 '14 at 11:34
