# An account has payment methods.  I'd like to know the payment methods for an account
# which meet some criteria.


# The 2 models
class Account
  include Ripple::Document

  many :payment_methods
end


class PaymentMethod
  include Ripple::Document

  one :account
  property :storage_state, String
end


# In Active Record I can do the following:
account = Account.first
account.payment_methods.retained

# since there can be a named scope such as:
class PaymentMethod
  scope :retained, :conditions => [ "storage_state = ?", "retained" ]
end


# I'm wondering what the best way might be to do this in Riak.

We'll see! I've been a bit surprised how little querying I've needed to do for the app I'm working on. At this point, I'm in "get some things working" mode. I'm now querying for strings and dates. I don't yet have enough real uses of querying in real apps to have a worthy pull request ready. I would think that would change over time. :)
