Hi, I am trying to get the hang of rails. It has been going well, except now I am trying to add an action to a controller and am having trouble. I have a LinkCategory class which extends activerecord. In its controller, I added a method 'display' which lists the categories with its links. I then created a new view, display.rhtml. Wehn I navigate to localhost:3000/link_categories/display page, my view is rendered, but the display method in the controller does not seem to be exectued. At first, I was running a find across link categories in the controller and then attempting to use it in the view: <code> def display @link_categories = LinkCategory.find(:all) end </code> When the view is rendered, I am told that @link_categories is a nil object. I know that query returns a number of rows. I tried shorting the method to ensure that it was being executed by adding a: redirect_to :action => 'list' at the very beginning of the method, but the display view is still rendered. I was wondering if I had misconfigured something, or neglected to add a mapping, that was keeping the code in the controller from being executed. I still have the default routes configured. Any help would be appreciated. Thanks.

Calling an action 'display' is one of those unwritten things that doesn't work. Rename it and you should be fine, perhaps 'show'. - Gabriel
