Ah, I see. Let me just explain. Since I'm using Rails I am calling this 
method with the block in a view or a template. My template language is 
Haml, and this is how it's called:

- fields_for_setting("site", "name") do |f|
  = f.label :value, "Site name", :index => nil
  = f.text_field :value, :index => nil

The = is a short hand for puts as you pointed out. But I don't see other 
possibilities than using put, otherwise the text field will not show up 
in the view.

How can I both use puts and make some content appear around the text 
field?
