Rails - Get the current url without the GET parameters -

-

request.url returns me : http://localhost:3000/page?foo=bar.

is there method can call http://localhost:3000/page , or have parse string strip parameters?

request.path should return you're looking if you're not concerned hostname. otherwise might try:

url_for(:only_path => false, :overwrite_params=>nil)
