Hi, I''m new to Rails but I develop in PHP somtimes. I figured that the
best way to learn Rails is to create a simple CMS. While I understand
the basics of ruby and rails, one issue has caught me: how can I set a
default ID for an action?
Here is my code for the index action in my pages controller:
def index
@page = Page.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @page }
end
end
However, when I load http://localhost:3000/pages , I get a message:
Couldn''t find Page without an ID
How can I make my application assume a default ID of 1 if none is
provided?

In Rails 2.0.x, the mapping is: GET => action => index => list of items GET /id => action => show => individual item identified by id Run rake routes to see how your HTTP verbs map to your controller/ action pairs. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
