Hi All  
The docs mention that raising ActiveRecord::Rollback from within a  
‘transaction’ block causes the transaction to rollback without  
reraising it. However, trying this in script/console gives this error:

NameError: uninitialized constant ActiveRecord::Rollback

Doing a recursive grep of /usr/lib/ruby doesn’t find any mention of  
ActiveRecord::Rollback!! Am I doing something wrong? What’s the  
‘right’ way to rollback a transaction explicitly from within a  
‘transaction’ block?

thanks

Well it’s defined in Activerecord’s base.rb (it just defined as class  
Rollback (but inside the AR module) which is why your search didn’t  
find it).  
and ActiveRecord::Rollback seems to exist for me.
