Easily handle parsing date fields in your Ecto schemas.

Include this in your schema and stop worrying about string dates! ``` field :some_date, ParsedDate ```

defmodule ParsedDate do
  use Ecto.Type

  def type, do: :date

  def cast(str_date) when is_binary(str_date) do
    case DateTimeParser.parse_date(str_date) do
      {:ok, date} -> {:ok, date}
      _ -> :error
    end
  end

  def cast(%Date{} = date), do: {:ok, date}
  def cast(_), do: :error

  def load(%Date{} = date) do
    {:ok, date}
  end

  def dump(%Date{} = date), do: {:ok, date}
  def dump(_), do: :error
end
