Xianfeng,

The responses so far are very good answers to the general question.  I think the best solution for your case is John's solution.  However,  I thought I might mention that the specific ruby code you posted could be simplified quite a bit.  I would write that as

my_array.join(', ') if my_array.is_a?(Array)

Actually, I just noticed that your method surrounds each element in the array with escaped double quotes.  If you want that, you could do

my_array.map{ |s| "\"#{s}\"" }.join(', ') if my_array.is_a?(Array)

Surely, we can all agree to call these something more chef-fy...a "buffet" or "serving dish".

Partials are a new feature in chef (just merged to master, in fact: https://github.com/opscode/chef/pull/498)

For now, I'm not sure there is a good solution. You can possibly use ERB to evaluate the a subtemplate and pass that into a template via variables.

<%
def output_array(s)
    str = ''
    if s.is_a?(Array)
       if s.length >= 1
          str = s.at(0)
          str = "\"#{str}\""
          if s.length > 1
             for i in 1..(s.length - 1)
                 w = s.at(i)
                 str = "#{str}, \"#{w}\""
             end
          end
