Hi,
I have a link that says:
<%= link_to_remote("Data", :update => 'pie_graph_div', :url
=> {
:action => :show_pie_graph, :mode => 'nums' }) %>
which calls *show_pie_graph*:
Controller:
def show_pie_graph
render :layout => false
@mode = params[:mode]
end
View:
<img src="/surveys/make_pie_graph/<%=@mode%>" />
But @mode on view always is nil.
I can see the :mode from the view by calling params[:mode] but not
from the controller.
What's the problem? Did I misunderstand something?
Thanks in advance,
- H

Set @mode before calling render. -- We develop, watch us RoR, in numbers too big to ignore.

You need to swap the lines in the controller. def show_pie_graph @mode = params[:mode] render :layout => false end The 'render' method uses the current state of the controller at the time it is called to setup the view. At that time, @mode is not yet set, so that is what the view sees. -----Original Message----- From: rails-bounces@lists.rubyonrails.org [mailto:rails-bounces@lists.rubyonrails.org] On Behalf Of Human Dunnil Sent: Monday, January 30, 2006 1:58 PM To: rails@lists.rubyonrails.org Subject: [Rails] params on controller and view Hi, I have a link that says: <%= link_to_remote("Data", :update => 'pie_graph_div', :url => { :action => :show_pie_graph, :mode => 'nums' }) %> which calls *show_pie_graph*: Controller: def show_pie_graph render :layout => false @mode = params[:mode] end View: <img src="/surveys/make_pie_graph/<%=@mode%>" /> But @mode on view always is nil.
