Validators

==========

.. module:: django.contrib.postgres.validators

These validators are available from the ``django.contrib.postgres.validators``

module.

``KeysValidator``

=================

.. class:: KeysValidator(keys, strict=False, messages=None)

    Validates that the given keys are contained in the value. If ``strict`` is

    ``True``, then it also checks that there are no other keys present.

    The ``messages`` passed should be a dict containing the keys

    ``missing_keys`` and/or ``extra_keys``.

    .. note::

        Note that this checks only for the existence of a given key, not that

        the value of a key is non-empty.

Range validators

================

``RangeMaxValueValidator``

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

.. class:: RangeMaxValueValidator(limit_value, message=None)

    Validates that the upper bound of the range is not greater than

    ``limit_value``.

``RangeMinValueValidator``

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

.. class:: RangeMinValueValidator(limit_value, message=None)

    Validates that the lower bound of the range is not less than the

    ``limit_value``.
