Great write up! Thanks a lot.

Would you maybe be interested in merging some of it with the Rails form helpers guide? http://guides.rails.info/form_helpers.html#building-complexforms
It really needs a comprehensive write up, like yours, before 2.3.
Email me if you’re interested.

Last note; In your final example, right at the very end, you still use the old way of instantiating new records with the new_1 key. It should simply be 5 :)

OK, the html didn’t show up. Trying again. There are two input elements named “creator[widget_attributes][0][id]“.

This should be definitely added to the official docs! I’ve already known most of this stuff but it was the *hard* way (aka trial and error). If I had read such an article when I started using rails I would have saved a lot of time…

Kudos again for the writing :)

Great post Trek! Very articulate and the [_delete] bit will be particularly useful to me. Thanks for taking the time to write it.

@Graham You’re right. I knew about the foos[] trick for arrays, but never used the foo[bar] trick for associative arrays. Probably a product of starting PHP in v3 and quitting shortly after v4 was out.

@Russ I HATE those snapshots. Until today I thought they were just like the adverts: part and parcel of using hosted wordpress. Some quick googling disabused me of that notion. They’re now off.

This explanation should be added to the official documentation.
