Hi, A store front a customer wants to GET /product/5/show. But for the application this is really GET /cart\_item/new/5 or even better /cart\_item/new?cart\_item[product\_id]=5 When the customer clicks add\_to\_cart they POST /product/5/show so that the url doesn’t confuse the user when any validation errors occur. But for the applicaiton this should be POST /cart\_item/create?cart\_item[quantity]=23 Can I use routing to check the request method something like the following? map.connect ‘product/:id/show’, :controller=\>‘cart\_item’, :action=\>‘new’, :id=\>/\d+/, :method=\>‘get’ map.connect ‘product/:id/show’, :controller=\>‘cart\_item’, :action=\>‘create’, :id=\>/\d+/, :method=\>‘post’ Thanks, Peter ---

You can verify post for certain methods in your controller by adding: class YourController \< ApplicationController verify :method =\> :post, :only =\> %w( action1 action2 etc… ) … Regards, Ian ---

This doesn’t seem to work. I am using Rails 1.1.4. Do I need a plugin for this to work? I see the error at the bottom of this email. Look at the poor routing docs [http://api.rubyonrails.com/files/vendor/rails/actionpack/lib/action\_controller/routing\_rb.html](http://api.rubyonrails.com/files/vendor/rails/actionpack/lib/action_controller/routing_rb.html) Nothing:S Peter =\> Booting WEBrick… /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action\_controller/routing.rb:49:in `test_condition': Valid criteria are strings, regular expressions, true, or nil (ArgumentError) from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action_controller/code_generation.rb:228:in `check\_conditions’ from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action\_controller/code\_generation.rb:226:in `check_conditions' from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action_controller/routing.rb:362:in `write\_generation’ from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action\_controller/routing.rb:557:in `generation_code_for' from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action_controller/code_generation.rb:19:in `indent’ from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action\_controller/routing.rb:553:in `generation_code_for' from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action_controller/routing.rb:492:in `each\_with\_index’ from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.3/lib/action\_controller/routing.rb:550:in `generation_code_for' ... 19 levels... from /usr/local/lib/ruby/gems/1.8/gems/rails-1.1.4/lib/commands/server.rb:30 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require’ from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active\_support/dependencies.rb:147:in `require’ from script/server:3 ---

I’m using edge rails and defining my routes using the simply\_restful plugin. It’s possible the http method conditions are only part of the latest routing code. I’m afraid I’m not sure. Tom ---
