ActsAsAccount implements a "Double Entry Accounting" system for your Rails-models.
It hooks into ActiveRecord and allows to add accounts to any model by
simply means of adding has_account to your model. Because the accounts
are connected via a has_many relation no migration to the account-holder
tables is needed.
We also hook into the ActionController request cycle to warn the developer if a request has left uncommitted changes in the system.
It is possible to configure if attributes (postings_count, balance, last_valuta) are persisted on the Account or if it is calculated on demand.
ActsAsAccount.configure do |config|
# Default values:
# config.persist_attributes_on_account = true
end
Enabling persistence means that the sending and receiving account will aquire a lock when making a transfer to ensure correct data. This can be problematic in a high load scenario where many transfers to the same accounts are processed in parallel.
Run the cucumber features from the acs_as_account gem, just execute
rake features:create_databasecucumber
You need to update the data in VERSION and Rakefile and run rake (because it uses GemHadar).
rake gem:push will push the version to rubygems.
