<< a has_many association starts no-op transaction for .new ActiveRecords
Reported by George Montana Harkin | June 24th, 2009 @ 12:21 AM | in 3.x
When building up an object to be saved later in a large transaction, I am adding Models to a has_many relation for another:
Timsheet has many TimesheetRevisions
timesheet = Timesheet.new do |t"
t.pay_period_id = 12
t.user_id = user_id
...
end
timesheet_revision = TimesheetRevision.new do |tr|
tr.timehsheet_status_id = timesheet_status_id
...
end
timesheet.timesheet_revisions<
Checking the log, right around the << I receive a BEGIN followed by a COMMIT.
It looks to be an issue with << always starting a transaction even if the model has not been saved yet. See line 115 of rails/activerecord/lib/active_record/associations/association_collection.rb

I've created a simple patch for this issue. It isn't very ruby so you'll probably want to clean it up.

- Tag changed from “has_many” to “bugmash, has_many”
Can a bugmasher verify this as errant behavior in master with a failing test?
