Instance Method Details

#cast(value) ⇒ Object

Type casts a value from user input (e.g. from a setter). This value may be a string from the form builder, or a ruby object passed to a setter. There is currently no way to differentiate between which source it came from.

The return value of this method will be returned from ActiveRecord::AttributeMethods::Read#read_attribute. See also: Value#cast_value.

value The raw input, as provided to the attribute setter.

def cast(value)
  return unless value

  super(add_dashes(value.to_s)) # super will encode the value as binary (Encoding::BINARY)
end

#deserialize(value) ⇒ Object

def deserialize(value)
  return unless value

  # If the value is a binary data, convert it to a hex string, and call cast(value)
  if value.is_a?(String) && value.encoding == Encoding::ASCII_8BIT
    super(value.unpack1("H*"))
  else
    super # foward to cast(value)
  end
end

#serialize(value) ⇒ Object

Casts a value from the ruby type to a type that the database knows how to understand. The returned value from this method should be a String, Numeric, Date, Time, Symbol, true, false, or nil.
