Where are Default Validation Error Messages in Rails 3.0?

Question

Where are the default validation error messages in Rails 3.0? What is the equivalent of ActiveRecord::Error.default_error_messages[:taken], for example? I have gotten as far as finding that ActiveModel handles the errors rather than ActiveRecord, but I can't find the errors themselves.

While this may not fully answer your question it provides you a way to customize the validation error messages (assuming that it's what you're trying to do): #809047 – Quittance

Actually, I'm not trying to customize them but just to use them in testing, making sure that the right error messages are raised. However, the link you gave is useful--it appears it's more complicated and less intuitive to created customized messages than in earlier versions! – Camphorate

http://github.com/rails/rails/blob/master/activemodel/lib/active_model/locale/en.yml

and

http://github.com/rails/rails/blob/master/activerecord/lib/active_record/locale/en.yml

:D

UPDATE:

Maybe you should try to add your own custom error messages?

# de.yml
activerecord:
  errors:
    messages:
      taken: "ist bereits vergeben"

# test_spec.rb
...
assert_equal(object.errors[field], I18n.t("activerecord.errors.messages.taken"))
...

Thank you, that's another useful bit of information. But how do I access the information in a Rails program? There must be a method in ActiveModel::Errors or somewhere else, isn't there? – Camphorate

What do you want to do exactly? – Persephone

For example, assert_equal(object.errors[field], ActiveRecord::Error.default_error_messages[:taken]) to test that the right error message has been given. It's not pragmatically that important to me, I can just use a text literal, but it doesn't seem the "pure" way to do things. – Camphorate
