automaticValidations()

Signature

automaticValidations() — returns void

Available in: model Category: Validation Functions

Description

Controls whether automatic validations should be enabled for a specific model. By default, Wheels can automatically infer validations from your database schema (e.g., NOT NULL fields, field length limits, etc.). This function lets you override that behavior at the model level — enabling or disabling automatic validations regardless of the global setting.

Parameters

Name	Type	Required	Default	Description
value	boolean	yes	—	Set to true or false.

Examples

1. Disable automatic validations for a single model
component extends="Model" {
    function config() {
        automaticValidations(false);
    }
}


Useful when automatic validations are enabled globally but a model requires custom validation handling.

2. Enable automatic validations explicitly for a model
component extends="Model" {
    function config() {
        automaticValidations(true);
    }
}


Ensures this model always applies database-inferred validations, even if global automatic validations are turned off.

3. Combining with custom validations
component extends="Model" {
    function config() {
        automaticValidations(false); // turn off inferred rules
        validatesPresenceOf("email");
        validatesFormatOf(property="email", regex="^[\w\.-]+@[\w\.-]+\.\w+$");
    }
}


Here, automatic validations are disabled, but explicit validation rules are still applied.
