Hi,
I've encountered a strange problem with exercise 1.5 of the Rails
Action Controller lesson, which doesn't turn out as described in the
exercise description.
The controller has the statements:
@controller_name = params[:controller]
@action_name = params[:action]
and the say_hello.rhtml has:
Controller is <%= @controller_name %>
<br/>
Action was <%= @action_name %> !
<br/>
When I run it, the screen shows nothing for the action, i.e.,
Controller is hello
Action is
I checked the log and the params[:action] is definitely "index".
After some fooling around, I determined that it works fine, if I
change the variable name to anything other than @action_name. For
example, if I make it "@action_nam" or "@actionx", then it works.
Any ideas why? Is "@action_name" a pre-defined variable or something,
which gets set internally after the controller changes the value?
