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

I ran into this problem as well with an old 2.3.5 Rails app that I inherited. I had the 5.0 version of the i18n gem installed. I saw that it needs the %{} syntax. Doing this in config/locales/en.yml did the trick:

en:
  activerecord:
    errors:
      full_messages:
        format: "%{attribute} %{message}"
