/flask_inputfilter/validators/date_after_validator.py

from __future__ import annotations

from typing import TYPE_CHECKING, Any, Optional, Union

from flask_inputfilter.exceptions import ValidationError

if TYPE_CHECKING:
    from datetime import date, datetime


class DateAfterValidator(BaseValidator):
    """
    Ensures that a given date is after a specified reference date. It supports
    both datetime objects and ISO 8601 formatted strings.

    **Parameters:**

    - **reference_date** (*Union[str, date, datetime]*): The date that the
      input must be later than.
    - **error_message** (*Optional[str]*): Custom error message if the
      validation fails.

    **Expected Behavior:**

    Converts both the input and the reference date to datetime objects and
    verifies that the input date is later. If the check fails, a
    ``ValidationError`` is raised.

    **Example Usage:**

    .. code-block:: python

        class EventInputFilter(InputFilter):
            def __init__(self):
                super().__init__()
