ActiveModel::ErrorMessagesWithoutAttributes

Extends ActiveModel::Errors to allow messages to be generated that do not use the attribute name. Sometimes, you just want to use a custom error message without jumping through a lot of rails hoops. With this gem, you specify an error message of '^Just use this error' and the attribute name will not be included in full_error messages for that attribute.

Add this line to your application's Gemfile:

gem 'activemodel-error_messages_without_attributes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activemodel-error_messages_without_attributes

  class User < ActiveRecord::Base
    validates :first_name,
      :presence => {:message => 'cannot be blank.'},
      :length => {:maximum => 64, :message => '^What are you thinking?'}

    validates :last_name, :presence => true
  end

  user_without_name = User.new
  user_without_name.valid?

  user_without_name.errors.full_messages_for(:first_name)
  # ["First name cannot be blank."]

  user_without_name.errors.full_messages_for(:first_name)
  # ["Last name can't be blank"]

  user_with_too_long_a_name = User.new('a'*65)
  user_with_too_long_a_name.valid?

  user_with_too_long_a_name.full_messages_for(:first_name)
  # ["What are you thinking?"]

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
