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

Here's one way:

child :contacts do
  node(:a1, :if => lambda { |c| c.is_foo? }
  node(:a2, :if => lambda { |c| c.is_foo? }

  node(:a3, :unless => lambda { |c| c.is_foo? }
  node(:a4, :unless => lambda { |c| c.is_foo? }
end

Not exactly the same but one possibility, another is:

node :contacts do |u|
  u.contacts.map do |c|
    if contact.is_foo?
      partial("contacta", :object => c)
      # or { :a1 => "foo", :a2 => "bar" }
    else
      partial("contactb", :object => c)
      # or { :a3 => "foo", :a4 => "bar" }
    end
  end
end
