I18n file to change an attribute's name

If you are using Active Record, use a locale file like the one below to change a model’s attribute’s human name.

en:
  activerecord:
    attributes:
      picture:
        explanation: Description

Without using the locale file:

ruby-1.9.2-p0 > Picture.human_attribute_name("explanation")
 => "Explanation"

Using the locale file:

ruby-1.9.2-p0 > Picture.human_attribute_name("explanation")
 => "Description"

Default values

For common attributes in several models, you can set a default human name like this:

de.yml

de:
  attributes:
    bez: Bezeichnung
    abk: Abkürzung

Works also with Mongoid

What works for Active Record, also works for Mongoid:

de:
  mongoid:
    attributes:
