Re: [Rails] build with nested forms

[Ariel Juodziukynas]

@item.item_item_properties.item_property_id is wrong, @item.item_item_properties is a collection, use `iip.object.item_property.name` and `iip.object.item_property_id` instead.

imagine @item.item_item_properties is something like an array [item_item_property1, item_item_property2], you can't call `item_property_id` on an array, you have to call it on one of the items inside it, and that "iip" variable, if you call `.object` on it you get that item from within the array.

check out the cocoon gem, it made nested forms really simple.
