I have an AR model named Order, and a field in the DB named expired. I
dont want this field to be modified from outside the model.
Therefore I have declared a private method expired=(value) in my Order
This works fine in development and production; If I call o.expired =
nil I get a "NoMethodError: Attempt to call private method", and if I
use o.update_attributes(expired => nil) I get
"ActiveRecord::UnknownAttributeError: unknown attribute: expired".
However in test environment donot get such exceptions. I can easily
use my private methods in my test environment, which is not what I expected.
