I observed this a few times, but not always happen, and if I down the
migration and run again, it often works.
My migration is really simple like:
Foo.find_each do |foo|
Occasionally, it reports success, but not actually updated the
attribute for the "bar" column of Foo object. It appears to just skip
the whole thing and report success. And as I said, if I down it and
run again, it has always worked.
Anybody else has seen this problem before? I'm using Rails 3.0.10 but
I had this problem with older 3.0.x versions as well.
