Emoji::Validator

We all love emojis, but sometimes unfortunately we can't handle them. Use these two validators to seamlessly ensure they don't end up messing up with your models.

Supports ActiveModel > 4

Tested against Ruby 2.5, 2.6 and 2.7

Depends on the unicode-emoji gem.

Add this line to your application's Gemfile:

gem 'emoji-validator'

And then execute:

bundle

Or install it yourself as:

gem install emoji-validator

Two validators are provided in the gem:

Use the NoEmojiAnywhereValidator to make all attributes of your ActiveRecord class automatically validate against emojis:

class Person < ActiveRecord::Base
  include Emoji::Validator::NoEmojiAnywhereValidator
end

person = Person.new(first_name: "😃", last_name: "😃")
person.valid? #false
person.errors.count #2

Use the NoEmojiValidator to make single attributes of your ActiveRecord class validate against emojis:

class Person < ApplicationRecord
  validates :first_name, no_emoji: true
end

person = Person.new(first_name: "John", last_name: "😃")
person.valid? #true
person.first_name = "😃"
person.valid? #false

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.
