Hi All, I have been told to post discussion based topic on here instead of the GitHub Issues. I thought this 'could' be a bug, but just need some clarification really. The issue I posted is here <https://github.com/rails/rails/issues/12597>, does anyone have any thoughts? Again: https://github.com/rails/rails/issues/12597 Thanks a lot.

If this was indeed accidental behaviour then the change could well be the side effect of another change. Using new in this way isn't something I've come across in quite a few years of using rails.

Hi Fred, Thanks for your reply. "Using new in this way isn't something I've come across in quite a few years of using rails." How would you initialise a new Task object given you have the @story instance available to you? @task = Task.new(:story_id => @story.id) ? If the above, I really don't see the point of the new and build methods for a has_many association... For a has_one association, I would be able to do: @task = @story.build_task So it makes no sense, that @task = @story.tasks.build doesn't do the same thing... As 'build' seems to just be an alias of 'new'. Thanks.

Hi Fred, Thanks for this. yes I can understand why it has never been a problem. It won't be too much of a problem for us either, as the collection variable e.g. @tasks, would normally be filtered with .where() or be ordered with .order(), therefore, they would be different instances. But I logged it as a bug, because it just doesn't seem right. I can't think of any reason why one would want the built instance added to the in memory collection... Anyway, I think I've been a bit cheeky on the Github issue, not sure if I'm going to get another response! Thanks for your reply though.
