Rails 3 constraints, named routes and form_tag

I have the following URL I match to show a subset of text from a book

/bookname/chapter1/line1/chapter2/line2

I have a route definition that works perfectly when entering a url in the browser however I cannot get a link_to or path name for this url

  match '/:book/:chapter1/:line1/:chapter2/:line2',     :to => "lines#showlines",     :constraints => {       :book => /\d*\s?\w{2,}/,       :chapter1 => /\d+/,       :line1 => /\d+/,       :chapter2 => /\d+/,       :line2 => /\d+/ },       :as => :showlines

I keep getting the error No route matches {:chapter1=>"1", :verse1=>"1", :controller=>"verses", :chapter2=>"1", :action=>"showverses", :verse2=>"3", :book=>"john"}

I have tried

<%=h link_to("link", showlines_path(:book=>'john',:chapter1=>'1',:chapter2=>'1',:line1=>'1',:line2=>'3')) %>

This is Rails 3.

Any pointers? Thanks!

FYI:

What I am trying to do is create a form to select a location in the book and then render it.

Thanks!

OK - at least I have a workaround....

removing the constraints allows link_to, etc to work. However, I have to deal with checking for properly formatted URL's in the controller.
