Question

I have a different subheader partial I want to render dependent on where I’m at in my application. How do I go about determining where I’m at via ruby? Or do I need to parse the URL?

Example :

If I’m at my root level I want to use /home/subheader, if I’m in controller ‘test’ I want to render /test/subheader, etc… etc…

basically looking for this part:

(in my application view)

<%- if  ############ %>
<%= render :partial => '/home/subheader' %>
<%- elsif ########### %>
<%= render :partial => '/test/subheader' %>
<%- else  %>
<%= render :partial => '/layouts/subheader' %>
<%- end %>

Thanks

You can use current_page?

if current_page? :controller => 'home', :action => 'index'
  do_this
end

or use the controller’s method controller_name

if controller.controller_name == 'home'
  do_that
end

If you’re using this in a per-controller basis, you should probably need layouts or use different templates, rendering different partials depending in controller/action is a code smell.

P.S: You could also try to get the params[:controller] and params[:action] variables, but I am not sure if they are passed correctly if your route is non the standard /:controller/:action
