Method: Hyperactive::Record::Persistent#with_transaction

Defined in:
lib/hyperactive/record.rb

#with_transaction(transaction, &block) ⇒ Object

Will execute block within a transaction.

What it does is just set the @transaction instance variable before calling the block, and unsetting it after.

This means that any classes that want to be transaction sensitive need to take heed regarding the @transaction instance variable.

For example, when creating new Record instances you may want to use get_instance_with_transaction(@transaction, *args) to ensure that the new instance exists within the same transaction as yourself.

See Hyperactive::List::Head and Hyperactive::Hash::Head for examples of this behaviour.
