Overview

Active Model BigInteger Type

::ActiveModel::Attribute type for integers that can be serialized to an unlimited number of bytes. This type is registered under the :big_integer key.

class Person
  include ActiveModel::Attributes

  attribute :id, :big_integer
end

person = Person.new
person.id = "18_000_000_000"

person.id # => 18000000000

All casting and serialization are performed in the same way as the standard Integer type.

#==, #as_json, #assert_valid_value,
#cast

::ActiveModel::Type casts a value from user input (e.g. from a setter).
#changed?

Determines whether a value has changed for dirty checking.
#changed_in_place?

Determines whether the mutable value has been modified since it was read.
#deserialize

Converts a value from database input to the appropriate ruby type.
#eql?

Alias for Value#==.
#hash,
#serializable?

Returns true if this type can convert value to a type that is usable by the database.
#serialize

Casts a value from the ruby type to a type that the database knows how to understand.
#type

Returns the unique type name as a ::Symbol.
#cast_value

Convenience method for types which do not need separate type casting behavior for user and database inputs.
