ActiveModel::Type::Integer
|
Defined in: | activemodel/lib/active_model/type/big_integer.rb |
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.

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