[Rails] Re: Strange behaviour with ActiveRecord has_many collections, Rails 4 compared to Rails 3

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.

"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?

I've always done @story.tasks.build(...)

The fact that this adds the built instance to the in memory collection has never been a problem for me
