Custom validation message in Rails - Override prefix

User.rb

class User < ActiveRecord::Base
  validates_uniqueness_of :email, message: 'has already taken'
end

# user = User.new(email: 'foo@bar.com')
# user.save! => User has already taken.

# If you wanna change the error message to "Your fucking account has already taken"

# just edit one file config/locales/en.yml
en:
  activerecord:
    attributes:
      user:
        email: 'Your fucking account'
  

'Your fucking account' --> LOL
