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:
@link_categories = LinkCategory.find(:all)
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.
