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  
[]:ActionController::Routing::PathSegment::Result

The trace ends with

/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action\_controller/base.rb:522:in  
`url_for' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action_view/helpers/url_helper.rb:27:in`send’  
/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action\_view/helpers/url\_helper.rb:27:in  
`url_for' /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/action_view/helpers/url_helper.rb:75:in`link\_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”.
