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

You should show some actual code so that people can assist you.

\<%= yield :meta %\>

Ok

this is application helper:

module ApplicationHelper  
def seo\_meta  
content\_for(:meta) do  
“”  
end  
end  
end

My template (application.html.erb):

\<%= yield(:meta) %\>  
…

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

\<%= seo\_meta %\>
