http request values converted wrong in special case

Hi,

I'm using Rails 2.3.4.

Following situation:
You have a call like "/books/show?name=the+name"
as you can see the space between "the" and "name" is correctly replaced by a "+"
now you change the route to "/:name" and create a link_to "example", :controller => :books, :action => :show, :name => "the name"
and you get "/the name" without the space replaced.
That's wrong I think!? It should also be replaced by a "+".

If it is not clear: it is only the case if you rename a route like I did above.

Edit: The Problem is: Rails should generate a valid and working url, an url like "/the name" is equivalent to "/the", that's no good deal. Rails should convert all chars of the passed vars the way like chars are always converted for urls. If a space becomes a "%20" or "+" doesn't matter but there are often many chars that need to be converted. At least we need something like h() for urls.

Yours Joern.
