output formated json with rails 3

Question

I use rails 3.0.3

A javascript auto complete needs data like this

{
 query:\'Li\',
 suggestions:[\'Liberia\',\'Libyan Arab Jamahiriya\',\'Liechtenstein\'         


        

Answer 1

I've seen something like this in a .erb:

<%= raw
  {
    :query       => @query,
    :suggestions => @customers.map{|c| "#{c.firstname} #{c.lastname}" },
    :data        => @customers
  }.to_json
%>

If thinking of preparing data to be consumed by other programs as presentation logic, this might make sense to you.

FWIW I like it.
