Fixed #23224 - Documented EmailValidator.

.. class:: EmailField([max_length=254, **options])

A :class:`CharField` that checks that the value is a valid email address.

A :class:`CharField` that checks that the value is a valid email address. It

uses :class:`~django.core.validators.EmailValidator` to validate the input.

.. versionchanged:: 1.8

        :exc:`TypeError` is raised.

        Defaults to `0`.

``EmailValidator``

------------------

.. class:: EmailValidator([message=None, code=None, whitelist=None])

    :param message: If not ``None``, overrides :attr:`.message`.

    :param code: If not ``None``, overrides :attr:`code`.

    :param whitelist: If not ``None``, overrides :attr:`whitelist`.

    .. attribute:: message

        The error message used by

        :exc:`~django.core.exceptions.ValidationError` if validation fails.

        Defaults to ``"Enter a valid email address"``.

    .. attribute:: code

        The error code used by :exc:`~django.core.exceptions.ValidationError`

        if validation fails. Defaults to ``"invalid"``.

    .. attribute:: whitelist

        Whitelist of email domains to allow. By default, a regular expression

        (the ``domain_regex`` attribute) is used to validate whatever appears

        after the @ sign. However, if that string appears in the whitelist, this

        validation is bypassed. If not provided, the default whitelist is

        ``['localhost']``. Other domains that don't contain a dot won't pass

        validation, so you'd need to whitelist them as necessary.

``URLValidator``

----------------

.. class:: URLValidator([schemes=None, regex=None, message=None, code=None])

------------------

.. data:: validate_email

    An ``EmailValidator`` instance that ensures a value looks like an

    email address.

    An :class:`EmailValidator` instance without any customizations.

``validate_slug``

-----------------
