Showing error messages.

Hi! I hve written validations to check the incoming data. Also in the view i am saying: <%= error_messages_for “model_name_here” %>. Now when i am trying to insert invalid data, it is not getting stored in the model(which is gud) but it is not ahowing any error messages on the view rendered…

How can i show these error messages? Plz help. Thx and regards, Swanand.
