In the README file of the ActiveRecord docs
(http://api.rubyonrails.com/files/vendor/rails/activerecord/README.html)
it says:
Transaction support on both a database and object level. The latter is
implemented by using Transaction::Simple
Just database transaction
Account.transaction do
david.withdrawal(100)
mary.deposit(100)
end
Database and object transaction
Account.transaction(david, mary) do
david.withdrawal(100)
mary.deposit(100)
end
But the second case does not seem to actually be implemented. Test
case:
from script/console I run
irb> a = Account.create
=> #<Account id: 2, name: nil, balance: 0.0>
irb> Account.transaction do
irb* a.deposit(10.00)
irb> raise
irb> end
RuntimeError:
[[snip]]
irb> a.balance #Oops db didn’t change but object did
=> 10.0
irb> a.reload
=> #<Account id: 2, name: nil, balance: 0.0>
irb> Account.transaction(a) do #this should fix it
irb* a.deposit(10.00)
irb> raise
irb> end
ArgumentError: wrong number of arguments (1 for 0)
from (irb):23:in `transaction’
from (irb):23
What am I doing wrong here?

Object level transactions have been deprecated in Rails 2, but you
can use a plugin to restore its functionality:

Shouldn’t this reference be removed from the documentation then?

You should only rely on well generated api docs on your local
computer and the official docs at api.rubyonrails.com (local docs
install is still best, especially if you’re on edge)

Please take a look at the official docs here:
(Peak Obsession)
What I quoted if from the 8th bullet point down.
I do us my locally generated RDocs but I cannot link to them very well
can I?

It must have slipped under the radar, I guess (it happens when it’s
on a summary page). It would be nice if you could submit a patch for
it so it doesn’t persist in later versions.

I don’t know what site you are using, but I can’t find it in the
official rails api docs at:
http://api.rubyonrails.com/classes/ActiveRecord/Transactions/
ClassMethods.html
It does come up at
http://www.railsapi.org/ActiveRecord::Transactions::ClassMethods
which means that unofficial rails api hasn’t been updated to the
latest version.
