I've got an application that needs to take action when new files appear
in a directory.
From a rails application, what would the easiest/best way to implement
When a new file appears, I'll need to call an action on a controller
with the filename.
Any ideas much appreciated.
How quickly does it need to be acted on? If one minute intervals are okay, setup a cron job to run a script via script/runner to process any files in that directory.
Otherwise look at using backgrounddrb to notify that a file has been deposited and needs processing...
