While trying to deal with error messages for attributes of models
using STI, I stumbled upon the human_attribute_name method...
# Transforms attribute key names into a more humane format, such
as "First name" instead of "first_name". Example:
# Person.human_attribute_name("first_name") # => "First name"
# Deprecated in favor of just calling "first_name".humanize
def human_attribute_name(attribute_key_name) #:nodoc:
I'm wondering if it really is deprecated.
It's still in use in validations for adding errors, and I think it's a
great solution for having a shared column in a base model that can be
reported as having an error differently depending on the subclass
For example, I have an Address model with subclasses of EmailAddress
and WebAddress and the "address" attribute will contain an email
address or a url for the respective classes.
By overriding human_attribute_name in my subclasses I can make my
error messages friendlier. If the method goes away, I'm not sure how
I'd do it.
