Retrieving ID from a POST URI

To note, I only have the URI in a string as its from a POST from an
external API as JSON Data.
Basically I need this:

http://www.someapp.com/events/12345

I just need the 12345

Obviously, params[:id] won't work so I'm not sure how to get this. I
tried this:

    url = data['referring_site']
    event_id = CGI::parse(URI::parse(url).query)

But it didn't work.
Where the referring_site was the URL in question.
Thanks

Is there anything wrong with:

data[‘referring_site’].split("/").last

Which will give you what you are looking for, assuming that is the limit of your URL?

Beauty!!!! Thats it.
Thank you.
Knew it was a string call, just not sure which one. Especially coming
from the PHP world.
Thanks again.

For what it's worth, a request to that URL should be sent using the HTTP
PUT method. If I'm not mistaken Rails should then automatically provide
"12345" in params[:id].

But, the provided solutions should work for your needs.
