after_validation callbacks are no longer executed if validation fails in rails3
Reported by Jeremy Davis | August 20th, 2010 @ 07:07 AM | in 3.0.2
In migrating our application from rails 2.3.x to rails 3 we have found that one of our post validation callbacks is being skipped. The callback is specifically concerned with reverting a changed record if the record was considered invalid.
I am including the callback method here for reference.
after_validation :revert_status_if_validation_fails
def revert_status_if_validation_fails
if self.status_changed? && (self.draft? || !self.errors.empty?)
self.status = self.status_was
end
end
Our expectation is that the after_validation callback will be run after validation regardless of the outcome of validation.

ActiveModel callbacks has following line of code.
def after_validation(*args, &block) options = args.extract_options! options[:prepend] = true options[:if] = Array.wrap(options[:if]) options[:if] << "!halted && value != false" options[:if] << "self.validation_context == :#{options[:on]}" if options[:on] set_callback(:validation, :after, *(args << options), &block) end
Notice options[:if] << "!halted && value != false"
It means that if validation returns false then do not call after_valdiation.
I have updated the doc http://github.com/lifo/docrails/commit/c24aa2f2dca52e1b0ee644e40738...
Whether after_validation should be called irrespective of the result is something that should be discussed with rails core team member.

In 2.3.x after_validation callback is called irrespective of the result of valid? . I confirmed it and it was suggested by Jeremy Davis and hence the ticket.
Attached is patch with test that fixes this issue in rails edge.
