Class Method Summary

::ActiveModel::Type::Value - Inherited

.new

Initializes a type with three basic configuration settings: precision, limit, and scale.

Instance Attribute Summary

::ActiveModel::Type::Value - Inherited

#limit, #precision, #scale,
#binary?

These predicates are not documented, as I need to look further into their use, and see if they can be removed entirely.

#mutable?, #serialized?

Instance Method Summary

::ActiveModel::Type::Value - Inherited

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

::ActiveRecord::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?
#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.

#force_equality?, #map,
#type_cast_for_schema

::ActiveRecord::Type casts a value for schema dumping.

#value_constructed_by_mass_assignment?
