For all my applicatino I use layout A. In this layout I have \<%= javascript\_include\_tag 'application.js' %\> and, in this javascript I have some code that I want to execute on all pages exept one. How can I exclude this javascript only for one page? ---

You could extract that code to a separate .js file and have a separate layout for that page that does not include the new js file. Colin ---

But I have to duplicate the layout code only to not include a .js? All the pages have the same layout. ---

Put all the common stuff in a separate file or files and yield to it/them from the layouts. Colin ---

You could stick \<%= yield :extra\_js %\> in the head section of the layout and then use content\_for :extra\_js with the include for the extra javascript file Fred ---

Yes that's a solution, thank you. ---

Can I use content\_for in a partial too? ---

Are you asking because you tried it and it didn't work? I don't see anything in the documentation that indicates it would NOT work in a partial. ---

It should work in partials, but will not work if you are rendering the partial in an ajax call ---
