As pointed out by Dave you can use the proposed solution to his linked question, i.e. by doing:

<%= javascript_include_tag params[:controller] %> 

The only thing you'd have to remember to do this is to name your javascript assets the names of the controllers - so home.js and sessions.js in your case (if I remember Rails' naming conventions correctly).

I have seen other ways of doing this though, which is useful if you want to include some javascript on pages associated with different controllers for whatever reason. This answer, I think, gives a very elegant solution.

First off, add the global javascripts to your manifest file, and include that in your application.html.erb layout file.

  # stuff
  <%= javascript_include_tag 'application' %>
  <%= yield :javascripts %>


 <%= yield :content %>

And then in the views where you would load specific javascripts simply add the following:

<% content_for :javascripts do %>
  <%= javascript_include_tag 'your_script' %>
<% end %>
