doubt with helper

Hi all

I need help

I have in my application helper this function:

def example   content_for(:meta) do     'okis dokis'   end end

And in my main layout view:

.. - yield(:meta) ...

And in other view layer this:

... - example ...

In development mode all this works, but in production in a server doesn't work. what is the problem, I can't explain


this is application helper:

module ApplicationHelper   def seo_meta     content_for(:meta) do       "<meta content='keywords' name='keywords' />"     end   end end

My template (application.html.erb):

<%= yield(:meta) %> ...

My other view that yields (index.html.erb):

<%= seo_meta %>
