Instance Method Details

#human_attribute_name(attribute_key_name, options = {}) ⇒ Object

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"

This used to be depricated in favor of humanize, but is now preferred, because it automatically uses the I18n module now. Specify options with additional translating options.
