Overview

A class that behaves like a boolean type, including rules for coercion of user input.

Values set from user input will first be coerced into the appropriate ruby type. Coercion behavior is roughly mapped to Ruby’s boolean semantics.

“false”, “f” , “0”, 0 or any other value in FALSE_VALUES will be coerced to false
Empty strings are coerced to nil
All other values will be coerced to true

[
  false, 0,
  "0", :"0",
  "f", :f,
  "F", :F,
  "false", :false,
  "FALSE", :FALSE,
  "off", :off,
  "OFF", :OFF,

.new

#limit, #precision, #scale

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

This class inherits a constructor from ActiveModel::Type::Value
