Newbie question: How to get an object in the Controller from a view's hidden field

Hi,    I'm trying to pass an object from the View to the controller as a hidden field. And am confused about a few things.

   For a hidden field, how do I pass a complete object to the controller?    For example, I have an object of type Issue, what should the second argument be in the following:

   <%= hidden_field("issue", ?, "value" => @issue) %>

   Is that even possible?

   Secondly, how would I access this object in the controller? params[:issue][:id] doesn't work.

   Someone suggested I should put the object in the session. How do I put and retrieve variables from the session?

   Any help would be appreciated.

Thanks, Anupam.

Fields are HTML not Ruby. They only hold text. You can do @issue.id then the controller is going to have to use .to_i to get an integer and Issue.find_by_id to locate the object.
