How to know if model attribute is protected?

rubyonrails-talk

I'm adding some meta-methods to a plugin and would really like to be able to know if an attribute is protected or not in my model. Unusually, googing hasn't turned up an answer. I know I could try an assignment and then rescue the exception (assuming the default whiny behaviour is on) but thats not a pleasing approach.

Thanks for any help or pointers,

Its not in the API description for ActiveRecord::Base, but it is mentioned in the source code for attr_protected. #protected_attributes returns an array of the attributes that are protected.
