Add ActiveRecord::Base#with_lock
Add a `with_lock` method to ActiveRecord objects, which starts
a transaction, locks the object (pessimistically) and yields to the block.
The method takes one (optional) parameter and passes it to `lock!`.
Before:
class Order < ActiveRecord::Base
def cancel!
transaction do
lock!
# ... cancelling logic
end
end
end
After:
class Order < ActiveRecord::Base
def cancel!
with_lock do
# ... cancelling logic
end
end
end
