Options

constraints

type: array [default option]

This required option is the array of validation constraints from which at least one of has to be satisfied in order for the validation to succeed.

includeInternalMessages

type: boolean default: true

If set to true, the message that is shown if the validation fails, will include the list of messages for the internal constraints. See option message for an example.

message

type: string default: This value should satisfy at least one of the following constraints:

This is the intro of the message that will be shown if the validation fails. By default, it will be followed by the list of messages for the internal constraints (configurable by includeInternalMessages option) . For example, if the above grades property fails to validate, the message will be This value should satisfy at least one of the following constraints: [1] This collection should contain 3 elements or more. [2] Each element of this collection should satisfy its own set of constraints.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
