Class Method Details

.coerce(type, value, options = {}) ⇒ Object

Convert value object to specific Type class

Examples:

Convert integer to sting type

ShallowAttributes::Type.coerce(String, 1)
  # => '1'

Convert string to custom hash type

ShallowAttributes::Type.instance_for(JsonType, '{"a"=>1}')
  # => { a: 1 }

Parameters:

  • type (Class) —

    the type class object

  • value (Object) —

    the value that should be coerced to the necessary type

  • options (Hash) (defaults to: {}) —

    the options to create a message with.

Options Hash (options):

  • :of (String) —

    The type of array

  • :allow_nil (boolean) —

    cast ‘nil` to integer or float

Returns:

  • the converted value object

  • 0.1.0
