Default block doesn't recurse

[danielhopkins]

>> h = Hashie::Mash.new({:foo => {}}){raise 'missing method'}
=> <#Hashie::Mash foo=<#Hashie::Mash>>
>> h.foo
=> <#Hashie::Mash>
>> h.bar
RuntimeError: missing method
>> h.foo.bar
=> nil

I believe that last line should throw an exception.

Since h.foo is not a Hashie::Mash, it wouldn't use the block, if I understand correctly...

[danielhopkins]

I think this is a miscommunication. Mash is recursive by default right?

When you inspect h.foo:

h.foo
=> <#Hashie::Mash>

It's a Mash. However, the default block that was assigned to the parent isn't carried down.

oh. yah, ignore me.... :P

If any of you are interested in sending up a pull, I'd be happy to review it!

I ran into a similar issue while subclassing a Hashie::Trash base class (properties were losing their :transform_with argument). I was using it to abstract requests to a really gnarly API. Solved it with an activesupport concern, works great.

DATE = lambda {|v| v.stamp('12/31/1999')}

module DateRange
  extend ActiveSupport::Concern
  included do
    property :start_date, :default => Date.today, :transform_with => DATE, :required => true
    property :end_date, :default => Date.today, :transform_with => DATE, :required => true
  end
end

class BaseRequest < Hashie::Trash
  credentials = Hashie::Mash.new(YAML::load(File.read(File.join(ENV['HOME'], '.fuglyapi'))))
  property :username, :default => credentials.username
  property :password, :default => credentials.password
end

class OrderRequest < BaseRequest
  extend ActiveSupport::Concern
  property :criteria, :default => 'all'
  property :campaign_id, :default => 'all'
end

class OrderIndexByDate < OrderRequest
  include DateRange
end

I am going to close this. Please reopen if you think we need to do something in Hashie for this.
