url encode equivalent in ruby on rails

Question

Is there an equivalent to PHP's urlencode in Ruby on Rails 2.3.5? (It encodes a string to be used in a query part of a URL) I googled it but all the answers seem to date back to before 2006 and seems dates. This is what I found. It seems a bit abnormal to call CGI::escape in a view.

Is there an equivalent helper function?

Thanks!

Answer 1

I believe the u helper method is what you're looking for:

<%=u "URL ENCODE <p>ME</p>" %>

I can't seem to find the documentation for that method, but if I find it in the near future I'll be sure to put a link in here.

Edit: You can find the documentation for this method here.

Answer 2

If you want to do it without ERB, you can use the following:

Rack::Utils.escape('http://example.com')
#=> "http%3A%2F%2Fexample.com"

Answer 3

This worked better for me than the Rack::Utils.escape:

URI::escape('http://example.com/?param=Hello World')

Because it replaced the spaces with %20 instead of +
