Hi all. I found could not use nested transaction any more in datamapper 0.10.x.
And seems this commit force dm use regular transactions http://github.com/datamapper/dm-core/commit/1a0edcdccba4d9540b42bbd2cc5ae239fbe1d296 So when you use start a transaction and modify data in other transaction, it will got this error `Lock wait timeout exceeded; try restarting transaction - (DataObjects::SQLError)`. -- Regards, Kai Chen -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
