ActsAsBits

ActiveRecord plugin that maintains massive flags in one column

Table Definition

Add "string" column into your model table.

ALTER TABLE users ADD operations varchar(255);

Model Definition

class User < ActiveRecord::Base
  acts_as_bits :operations, %w( create read update delete )
end

Usage

user = User.new
user.create?        # => false
user.create = true
user.delete = true
user.operations     # => "1001"
user.create?        # => true

User.create!(:update => true, :read=>false)

Advanced

"(column_name)=" enables to fill up values with argument that is true/false. This is useful for initial setting like all allow/deny.

user = User.new
user.operations     # => "0000"

# set all green
user.operations = true
user.operations     # => "1111"

# set all red
user.operations = false
user.operations     # => "0000"
