BlankAttributes

Blankable attributes for the ActiveRecord model.

Add this line to your application's Gemfile:

gem 'blank_attributes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install blank_attributes

class User < ActiveRecord::Base
  blank_attributes :name, :email
end

And use it:

user = User.new(name: '', email: ' ', token: ' ')
user.valid?
user.name # => nil
user.email # => nil
user.token # => " "

For preparing values there is used the before_valid callback.

• String

"" # => nil
" " # => nil

• Array

[""] # => []
[" "] # => []
["", 1] # => [1]
