Pass variable to layouts

Rails
1

I have this code(i use devise this is a redirect for user sign in):

layout :layout_by_resource

def layout_by_resource
if devise_controller? && resource_name == :user && action_name ==
‘new’

  "devise"
else
  "application"
end

end

In my devise layout i use some variables,(from example i use @lesson)
but i don’t know how to pass it to layout.

I try this in my aplication controller but seems like my css isn’t
working to any page.
layout ‘devise’
before_filter :set_constants

def set_constants
   @lesson=Lesson.all
   @sublesson=Sublesson.all
end

Thanks!

It’s no different to passing content to any other view - instance
variables set by the controller are copied to the view.
