Having a strange problem with a rails model I just created.

Here are my validations:

validates_presence_of :from_name, :message => 'Please provide a from name.'
validates_presence_of :from_email
validates_presence_of :giftition_plan_id

I'm having issues using errors.full_messages as well as f.error_messages in my form:

g = Giftition.create
g.errors.first
=> ["from_name", "Please provide a from name."]
>> g.errors.full_messages
=> ["{{attribute}} {{message}}", "{{attribute}} {{message}}", "{{attribute}} {{message}}"]

I'm just getting "{{attribute}} {{message}}". Any ideas?

UPDATE: I've uninstalled rails 3 and all the gems that were installed with it and that made the problem go away. It's not a fix though... I would still like to have rails 3 installed.
