Undefined Method 'rewrite' when calling link_to

Whenever I try to pass an options hash to the link_to method (or
url_for, or button_to) I get this error:

undefined method `rewrite’ for

The trace ends with

url_for' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action_view/helpers/url_helper.rb:27:insend’
url_for' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action_view/helpers/url_helper.rb:75:inlink_to’

url.rewrite is defined in a module named “url_rewriter.rb”, so I know
it;s there.

Why is this happening?

Figured it out. I had a route with a parameter named ‘url’. Apparently,
that was confusing Rails; I assume ‘url’ is reserved (or at least
reserved from a practical point of view).

Funny, but testing in console worked fine. This seems like a problem -
if it fails in the real world, it should fail in console (else what’s
the point of checking your routing in console?).

Something similar happened once when I named a model “file”.
