Hi everyone, I'm new with ruby and datamapper (I'm a Java and Python developer), and I'm giving the ruby world a shot.
I sadly didnt find the answer in the docs (very very strange indeed), and after some search I found the answer in the group, but its from 3 years ago, maybe something has changed. How can I use transactions with datamapper? I always start a transaction from a current instance? What happens if i want to change the state of multiple entities? What i found is: To wrap simple stuff inside a *transaction* you do: myInstance.*transaction* do myInstance.some_value = some_other_value myInstance.do_something end To wrap several updates of several instances in side a *transaction* you do: myInstance.*transaction*.*link*(anotherInstance) do myInstance.some_value = some_other_value anotherInstnace.some_value = some_other value end --- Why the transaction is attached to the instance? The "link" API is very weird. Wouldn't be nicier a global method to start/commit/rollback transactions? And how can I force a rollback? -- You received this message because you are subscribed to the Google Groups "DataMapper" group. To post to this group, send email to datamapper@googlegroups.com.
