Question

I have a Rails 3 application that is using the 960 grid CSS layout(s). There are a couple of different views that stretch in width and I am trying to come up with a good way to dynamically change out those classes.

For Example:
My Devise Controllers (Sessions, Passwords, etc) all use a certain class to restrict the width to 340px, while most of my other controllers use another class to restrict the width to 540px

So my 340px layout uses class names grid_6 push_5, while my 540px layout uses grid_10 push_3

Anyway to grab the accessed controller in the application_controller? My thinking is to just get the controller and have a switch statement that sets the class names in a helper_method.

Thoughts?

I was able to figure it out, thanks to this post: Determine the requested Controller in – ApplicationController

Here is how I ended up doing it (application.html.erb):

<%= render :partial => 'common/content_container', :locals => { :controller => params[:controller] } %>

content_container partial:

<% case controller
    when "sessions", "passwords"
        container_div_grid_number = "6"
        container_div_push_number = "5"
    else
        container_div_grid_number = "10"
        container_div_push_number = "3"
    end 
%>

<div class="grid_<%= container_div_grid_number %> push_<%= container_div_push_number %> ">
    <div class="top_<%= container_div_grid_number %>"></div>
    <div class="middle_<%= container_div_grid_number %>">
        <%= yield %>
    </div>
    <div class="bottom_<%= container_div_grid_number %>"></div>
</div>
