Why doesn't Rails' “errors.full_messages” replace attribute and message variables?

Question

Having a strange problem with a rails model I just created.

Here are my validations:

validates_presence_of :from_name, :message => \'Please provid         


        

Answer 1

Here's my complete config/locales/en.yml that solves the attribute, message, count, and model issues. I got this from the RoR docs here: http://guides.rubyonrails.org/i18n.html

en: activerecord: errors: full_messages: format: "%{attribute} %{message}" template: header: one: "1 error prohibited this %{model} from being saved" other: "%{count} errors prohibited this %{model} from being saved"

Answer 2

I fixed locally by removing i18n-0.5.0.

experimenting with i18n-0.4.0 yields (while returning the correctly interpolated string):

The {{key}} interpolation syntax in I18n messages is deprecated. Please use %{key} instead.

I guess 0.5.0 turns up the pain by outputting non-interpolated strings.

i18n is required by activesupport, so the way I got around loading the most recent version (0.5.0) is:

in config/preinitializer.rb ('secret' lifecycle hook that loads before activesupport):

require 'rubygems'
begin
  gem 'i18n', "~> 0.4.0"
rescue LoadError
  # no biggie, optional anyway
end
