示例1: Required
// Required adds a "required" validation to the attribute.
// See http://json-schema.org/latest/json-schema-validation.html#anchor61.
func Required(names ...string) {
var at *design.AttributeDefinition
if a, ok := attributeDefinition(false); ok {

incompatibleAttributeType("required", at.Type.Name(), "an object")
} else {
at.Validations = append(at.Validations, &design.RequiredValidationDefinition{Names: names})
