========== 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``.
