init(self, errorMessage, minLength=None, maxLength=None, allowNull=None)
(Constructor)

source code

Creates a new StringLengthValidator with a given error message, permissable lengths and null-string allowance.

Parameters:

errorMessage - the message to display in case the value does not validate.
minLength - the minimum permissible length of the string.
maxLength - the maximum permissible length of the string.
allowNull - Are null strings permissible? This can be handled better by setting a field as required or not.
