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


class KeysValidator(keys, strict=False, messages=None)[source]

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 that this checks only for the existence of a given key, not that the value of a key is non-empty.

Range validators


class RangeMaxValueValidator(limit_value, message=None)[source]

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


class RangeMinValueValidator(limit_value, message=None)[source]

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