Hello, I''m using class RestClient for communication between server and client. One example is: params = {:status => "finished"} resource = RestClient::Resource.new "http://localhost:3000/BuildJob/220376999" begin resource.put params, :content_type => ''text/plain'' rescue Exception => err puts err.to_s end where "status" is a string field in model class "BuildJob" and "220376999" is the id of the BuildJob. What I want to do is updating the field "status" in the model "BuildJob". I always get the error: "HTTP status code 500" I''m already using the following command to retrieve information about build jobs: xml = RestClient.get "http://localhost:3000/BuildJob?status=pending" This code is functioning without errors. Any idea what''s wrong? Thanks Martin -- Posted via http://www.ruby-forum.com/.
