You will learn http://guides.rubyonrails.org/v3.2.13/active_record_validations_callbacks.html how to validate the state of objects before they go into the database, and how to perform custom operations at certain points in the object life cycle. After reading this guide and trying out the presented concepts, we hope that you'll be able to: Understand the life cycle 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 life cycle Create special classes that encapsulate common behavior for your callbacks Create Observers that respond to life cycle events outside of the original class Chapters The Object Life CycleValidations OverviewWhy Use Validations?

API , the i18n wiki is available here . From rails 2.2 onward the I18n API is bundled as a dependency gem for rails. It is always a good practice to separate out, constant stuffs exposed to user , like https://codedecoder.wordpress.com/2013/09/11/customize-error-message-with-locales-rails/ validation error messages , flash notices etc in locales. If you structure your code https://github.com/jeremydurham/custom-err-msg like this from beginning, it will be easy for you to display the message in any language, the default is English. So by default rails will load all the messages from en.yml file. If say your site is in Germany and you want to show the validation message in German language. Then you will write all the validation message error messages in de.yml file and set the default language to :de in application.rb file with the below line config.i18n.default_locale = :de So now rails will try to look for the message in de.yml file. At any point, you can make rails to load a specific language file any time by passing locales parameter in URL Example : http://my_xyz.com/sigin?locales=en # it will load all the locales from en.yml extensions like devise.en.yml, rest.en.yml etc http://my_xyz.com/sigin?locales=de # it rails error messages will load all the locales from de.yml extensions like devise.de.yml, rest.de.yml etc The best way is to provide the extension in domain name itself Example: http://my_xyz.com.en http://my_xyz.com.de Above explanation is just a Introduction of locales and I will not get into more detail here. You may read the reference provided below. Let us move our validation error message to locals. Below, is the current validation class User < ActiveRecord::Base validates :source_system, :source_system_id validates_uniqueness_of :source_system_id, :message => "ID has already been taken" validates :entity_type, :inclusion => {:in => %w(Customer User), :message => "should be Customer or User"} validates :target_system, :inclusion => {:in => %w(LOCAL OPENAM), :message => "should be LOCAL or OPENAM"} end We can move these validation message to en.yml file locales. I have also shown providing custom name to the model and its attributes. But let us first remove the message from the user model, we do not need them as we are now setting the message in the locals class User < ActiveRecord::Base validates :source_system, :source_system_id validates_uniqueness_of :source_system_id validates :entity_type, :inclusion => {:in => %w(Customer User)} validates :target_system, :inclusion => {:in => %w(LOCAL OPENAM)} end Below is the code in config/locales/en.yml file en: activerecord: models: user: "Customer" attributes: user: email: "Email address" errors: models: user: attributes: source_system_id: blank: "must fill %{attribute}" taken: " Id User already provisioned" en

Rails 3 and Ruby 1.9 Custom Error Message is Rails 3 and Ruby 1.9 compatible Usage Sometimes generated error messages don't make sense. validates_acceptance_of :accepted_terms, :message => 'Please accept the terms of service' This generates the error message: Accepted terms Please accept the terms of service This plugin uses the carat (^) to omit the name of the attribute from error messages: validates_acceptance_of :accepted_terms, :message => '^Please accept the terms of service' This now generates: Please accept the terms of service CREDITS This plugin was originally written by David Easley (easleydp@gmail.com) Contact GitHub API Training Shop Blog About © 2016 GitHub, Inc.
