How to use Yard to document rails enum type

Question

I have an ActiveRecord class similar to this:

class User < ActiveRecord::Base

  # How do I document this?
  enum status [:registering, :active, :suspended, :deleted]
end

status attribute is used to build a state machine. How do I document that line of code using yard? The documentation needs to contain explanation of status attribute and all it's possible states.

Answer 1

Just list all options as comma separated list.

class User < ActiveRecord::Base

  # @!attribute [rw] status
  #   @return [:registering, :active, :suspended, :deleted]
  enum status [:registering, :active, :suspended, :deleted]
end

If you are not sure about type definition, you may consult with YARD Type Parser:

Answer 2

class User < ActiveRecord::Base

  # @attr [Enumerable<Symbol>] status
  enum status [:registering, :active, :suspended, :deleted]
end
