Question

I have several elements that are needed in each view and trying to set them in the application controller (which doesn’t work)…

class ApplicationController < ActionController::Base
  protect_from_forgery

  @top_categories = Category.top.limit(10)

end

How could I make that global data available in all views?

Answer 1

You could wrap that in a function and specify as a helper for example:

class ApplicationController < ActionController::Base    
    helper_method :top_categories

    def top_categories
        Category.top.limit(10)
    end
end

This will be available in all views and controllers
