Ah yes, I should have mentioned that caveat about form.inputs (I don’t use it often enough, so it wasn’t an issue for me)

Great, thanks Justin! I’ll look into it when I have time and file reports, pull requests, etc.

Thanks for the direction!

Hi, looks like if there’s an object, we expect/assume that it has reflections. It’s around line 460 of formtastic.rb. So you’d either need to offer the reflection object, or we need to check that it exists before calling it.

It’s not clear to me which way we should roll, need to look into where Rails 3 / ActiveModel is headed. Please fire up an issue on Github and we’ll take a look.

For some instant gratification, you can probably change line 459 from:

if @object.present?

to:

if @object.present? && @object.respond_to?(:reflections)
