 h5. Pessimistic Locking
 
-Pessimistic locking uses a locking mechanism provided by the underlying database. Passing +:lock => true+ to +Model.find+ obtains an exclusive lock on the selected rows. +Model.find+ using +:lock+ are usually wrapped inside a transaction for preventing deadlock conditions.
+Pessimistic locking uses a locking mechanism provided by the underlying database. Using +lock+ when building a relation obtains an exclusive lock on the selected rows. Relations using +lock+ are usually wrapped inside a transaction for preventing deadlock conditions.
 
 For example:
 
 <ruby>
 Item.transaction do
-  i = Item.first(:lock => true)
+  i = Item.lock.first
   i.name = 'Jones'
   i.save
