Hi, I have a DB with table TABLENAME, column COLUMN and an active resource client trying to connect to the DB. When i do Tablename.find(:all) => i get all the entries from the table But Tablename.exists?(:column => value) always returns false I verified that the above command works from rails console. Dont understand why it always returns false even when there are valid records. And in the rails server terminal i see a request for this cmd failing as Started HEAD "/tablenames/columnnamevalue.json" for 127.0.0.1 at Mon Jun 18 13:02:11 -0700 2012 ActionController::RoutingError (No route matches [GET] "/tablenames/columnnamevalue.json"): actionpack (3.2.4) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'' actionpack (3.2.4) lib/action_dispatch/middleware/show_exceptions.rb:56:in `call'' railties (3.2.4) lib/rails/rack/logger.rb:26:in `call_app'' railties (3.2.4) lib/rails/rack/logger.rb:16:in `call'' actionpack (3.2.4) lib/action_dispatch/middleware/request_id.rb:22:in `call'' rack (1.4.1) lib/rack/methodoverride.rb:21:in `call'' rack (1.4.1) lib/rack/runtime.rb:17:in `call'' Can anyone tellme why its failing? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
