= route_name_for http://thoughtpropulsion.com == DESCRIPTION: Rails helper to look up (named) route name given current request URI. Adds route_name_for method to controllers and views. == FEATURES/PROBLEMS: It only finds named routes of course, so sometimes it'll return nothing (if you give a path for which there) is no named route. == SYNOPSIS: If you have routes like this: map.home '', :controller => 'home' map.login 'login', :controller => 'home' You might like to define this helper in your ApplicationController: def body_class route_name_for request.request_uri, {} end And then call it from your application layout like this: So that when you browse to '/login', your page will have: … And when you you browse to '' or '/', your page will have: … Then you can match that in your CSS rules with a selector like this: body.login … { … } == REQUIREMENTS: Rails 2.1.0 or later. Also note: this code is highly dependent upon Rails' implementation of the ActionController::Routing::RouteSet implementation. In particular, the optimization to that class found in recognition_optimisation.rb (sic). The upside of this tight coupling is that this add-on performs as well as Rails native routing. The downside is that Rails may (will) change and this RubyGem will have to track those changes. == INSTALL: sudo gem install Bill-route_name_for See also http://gems.github.com/ == LICENSE: (The BSD License) * Copyright (c) 2008, Thought Propulsion * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions are met: * * Redistributions of source code must retain the above copyright * notice, this list of conditions and the following disclaimer. * * Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. * * Neither the name of the Thought Propulsion nor the * names of its contributors may be used to endorse or promote products * derived from this software without specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY Thought Propulsion ''AS IS'' AND ANY * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE * DISCLAIMED.
