Accessing the child instance in a RABL template

Question

I have a RABL template as shown below

object @user
attributes :name
child :contacts do
  # does not work
  if contact.is_foo?
    attributes :a1, :a2
  else
         


        

Answer 1

Another approach to keep things DRY:

contacts/show.json.rabl

object @contact
node do |contact|
    if contact.is_foo?
        {:a1 => contact.a1, :a2 => contact.a2}
    else
        {:a3 => contact.a3, :a4 => contact.a4}
    end
end

users/show.json.rabl

object @user
attributes :name
child :contacts do
    extends 'contacts/show'
end
