end
end
end

undefined method `list' for #<#<Class:0xb32881c>:0xbc96f84>

Answer 1

You are trying to call a method "auto-list" on your "xml" object, but this is not a a valid method name, because of the dash.

Method names can only contain the following: letters, numbers, underscores, "?", "!" and "=".

Answer 2

The easiest way is to just use the "tag!" command, like this:

xml.autos do               
  xml.tag! 'auto-list' do
    @autos.each do |offer|
      xml.offer do
      end
    end
  end
end
