error_wrapping in active_model_helper and nil errors
Reported by ronin-34500 (at lighthouseapp) | January 19th, 2010 @ 10:51 PM
I'm running into an issue with MongoMapper and Rails 3. The problem occurs in actionpack/lib/action_view/helpers/active_model_helper.rb in the error_wrapping method. The problem is that when it gets to "object.errors[@method_name].any?", there are no errors present, and it throws the following error:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.any?
I was able to get around this problem by changing that line to this:
if object.respond_to?(:errors) && object.errors.respond_to?(:full_messages) && object.errors.present? && object.errors[@method_name].any?

I've since switched to Mongoid which fully supports Rails 3. MongoMapper only has partial support, so I'm sure this was an issue with that library.
Please reject the ticket.

Done! Thanks Robby!
