Signature

validateOnCreate() — returns void

Available in: model Category: Validation Functions

Description

Registers one or more validation methods that will be executed only when a new object is being inserted into the database. This is useful for rules that should apply strictly at creation and not during updates. You can also control whether the validation runs using the condition and unless arguments.

Parameters

Name	Type	Required	Default	Description
methods	string	no	—	Method name or list of method names to call. Can also be called with the method argument.
condition	string	no	—	String expression to be evaluated that decides if validation will be run (if the expression returns true validation will run).
unless	string	no	—	String expression to be evaluated that decides if validation will be run (if the expression returns false validation will run).

Examples

1. Validate new objects before insertion
function config() {
 validateOnCreate("checkPhoneNumber");
}

function checkPhoneNumber() {
 // Ensure area code is '614'
 return Left(this.phoneNumber, 3) == "614";
}

2. Register multiple methods for validation on creation
function config() {
 validateOnCreate("checkPhoneNumber, checkEmailFormat");
}

function checkEmailFormat() {
 // Ensure email contains '@'
 return Find("@", this.email);
}

3. Conditional validation using `condition`
function config() {
 // Only validate phone number if the country is US
 validateOnCreate("checkPhoneNumber", condition="this.country == 'US'");
}

4. Skip validation under certain conditions using `unless`
function config() {
 // Skip phone number validation if user is a guest
 validateOnCreate("checkPhoneNumber", unless="this.isGuest");
}
