Settings API Reference Draft v1.0.2

Data Validation for Elixir.

Implementation of this behaviour should be set in validator options as :error_renderer or in :draft application config with same key. Common pattern is to expect :message key in validator options and if it not set use default_message (use get_message function for it). Result of message function appears in Draft.errors error tuple as last element, for those validators who use Draft.Validator.ErrorMessage (in general they should).

example

iex> {:ok, _value} = Draft.Type.Datetime.cast("01-01-1900", [])

iex> {:ok, _value} = Draft.Type.Datetime.cast("1900-01-01", [])

iex> {:ok, _value} = Draft.Type.Datetime.cast("2016-02-29T22:25:00-06:00", [])
iex> {:ok, _value} = Draft.Type.Datetime.cast("2023-02-01T14:51:53.468132Z", [])

iex> {:error, _reason} = Draft.Type.Datetime.cast("1900-91-91", [])
