Use helper method in JSON with RABL?

json, rabl, ruby-on-rails

Solution

You can do that using `node`:

collection @calls
attributes :time, :destination, :duration
node(:source) { |call| format_destination(call.source) }

Problem

I have a simple `index.json.rabl` file with the following content: ``` collection @calls attributes :time, :destination, :source, :duration ``` I also have a helper method which replaces the `source` value with a company name: ``` def format_destination(destination_number) case destination_number when "12345 "Name One" when "67891" "Name Two" else destination_number end end ``` Is it possible to replace the `:source` attribute in the RABL file with the helper method?
