I found.

     a = ["a", "b", "c"]     @contents = a.map{|item| "'" + item + "'"}.to_sentence :connector => ","

Thanks~ ^^

Hi,

Then... How can remove last ',' easily?

for example, with array

a = ["a", "b", "c"]

  I want to get a string "'a', 'b', 'c'".

but a.map{|item| "'" + item + "',"} gives "'a', 'b', 'c',".

I want to remove last ','.

What is the best way to achieve this?

Thanks.

what about @contents = a.map{|item| "'" + item + "'"}.join(",") or @contents = "'" + a.join("','") + "'"
