It is a replacement for act_as_sequence, where you can specify a lambda to determine how to generate the scope.

This version removes global lock on a table and uses pg_advisory_lock.

[Breaking change]

Now sequenced_on lambda accepts only hash of parameters and not ActiveRecord objects:

sequenced_on ->(r) { { bank_account_id: r.bank_account_id } }

instead of:

sequenced_on ->(r) { where(bank_account_id: r.bank_account_id) }

To publish a new version to rubygems, update the version in lib/sequence_on/version.rb, and merge.
