Rails Command Line Tools and Rake Tasks Caching with Rails Contributing to Rails Contribute Credits Active Record Validations and Callbacks This guide teaches you how to hook into the lifecycle of your Active Record objects. You will learn how to validate the state of objects before they go into the database, active record errors and how to perform custom operations at certain points in the object lifecycle. After reading this guide and trying out the presented concepts, we hope that you'll be able to: Understand the lifecycle of Active Record objects Use the built-in Active Record validation helpers Create your own custom validation methods Work with the error messages generated by the validation process Create callback methods that respond to events in the object lifecycle Create special classes that encapsulate common behavior for your callbacks Create Observers that respond to lifecycle events outside of the original class Chapters The Object LifecycleValidations OverviewWhy Use Validations?

<%= msg %>
<% end %> However the app's default locale is not English and in my language the structure of the full_messages is kinda unnatural: {{attribute}} {{message}} I saw from the source of generate_full_messages that I can localize the format and so in my locale's yml file (bg.yml) I http://stackoverflow.com/questions/4527708/rails-3-full-error-messages-format added this: bg: activerecord: errors: full_messages: format: "[...]" However the format of the validation errors stays the same. ruby-on-rails share|improve this question asked Dec 24 '10 at 18:10 zbrox 83821226 What format do you want? –Zabba Dec 24 '10 at 21:40 The specifics is not important. I want it to start with a specific word then {{attribute}} {{message}} because without this word it sounds awkward in my language. –zbrox Jan 4 '11 at 12:44 add a comment| 3 Answers 3 active oldest votes up vote 7 down vote accepted don't know if it can help, but a locale file for Bulgarian is available on Github. you may also try this (should work according to rails guides): bg: errors: format: "%{message}" messages: &error_messages empty: "Something something %{attribute} something something" this blog post and this stack overflow issue also talk about weird {{attribute}} {{message}} structures. Seems caused by a conflict between two I18n gems installed on the same server. share|improve this answer edited Oct 5 '11 at 0:50 answered Oct 5 '11 at 0:45 m_x 7,74452849 add a comment| up vote 8 down vote Change your current code <% @object.errors.full_messages.each do |msg| %>1.2.6 2.0.0 2.0.3 2.1.0 (0) 2.2.1 (0) 2.3.2 (0) 2.3.8 (0) 3.0.0 (38) 3.0.5 (0) 3.0.9 (-2) 3.1.0 (0) 3.2.1 (0) 3.2.3 (0) 3.2.8 (0) http://apidock.com/rails/activemodel/errors 3.2.13 (0) 4.0.2 (0) 4.1.8 (0) 4.2.1 (0) 4.2.7 (0) What's this?

A minimal implementation could be: class Person # Required dependency for ActiveModel::Errors extend ActiveModel::Naming def initialize @errors = ActiveModel::Errors.new(self) end attr_accessor :name attr_reader :errors def validate! errors.add(:name, "cannot be nil") if name.nil? end # The following methods are needed rails 3 error to be minimally implemented def read_attribute_for_validation(attr) send(attr) end def Person.human_attribute_name(attr, options = {}) attr end def Person.lookup_ancestors [self] end end The last three methods are required in your object for Errors to be able to generate error messages correctly and also handle multiple languages. Of course, if you extend your object with ActiveModel::Translation you will not need to implement the last two. Likewise, using ActiveModel::Validations will handle the validation related methods for you. The above allows you to do: person = Person.new person.validate! # => ["cannot be nil"] person.errors.full_messages # => ["name cannot be nil"] # etc..
