Installation

Instructions

Just drop into your modules folder or use CommandBox to install

box install cbvalidation

The module will register several objects into WireBox using the @cbvalidation namespace. The validation manager is registered as ValidationManager@cbvalidation. It will also register several helper methods that can be used throughout the ColdBox application.

Mixins - Helper Methods

The module will also register the following methods in your handlers/interceptors/layouts/views

• validate()

• validateOrFail()

• getValidationManager()

• validatehasValue()

• validateIsNullOrEmpty()

• assert()

/**
 * Validate an object or structure according to the constraints rules.
 *
 * @target An object or structure to validate
 * @fields The fields to validate on the target. By default, it validates on all fields
 * @constraints A structure of constraint rules or the name of the shared constraint rules to use for validation
 * @locale The i18n locale to use for validation messages
 * @excludeFields The fields to exclude from the validation
 * @includeFields The fields to include in the validation
 * @profiles If passed, a list of profile names to use for validation constraints
 *
 * @return cbvalidation.model.result.IValidationResult
 */
function validate()

/**
 * Validate an object or structure according to the constraints rules and throw an exception if the validation fails.
 * The validation errors will be contained in the `extendedInfo` of the exception in JSON format
 *
 * @target An object or structure to validate
 * @fields The fields to validate on the target. By default, it validates on all fields
 * @constraints A structure of constraint rules or the name of the shared constraint rules to use for validation
 * @locale The i18n locale to use for validation messages
 * @excludeFields The fields to exclude from the validation
 * @includeFields The fields to include in the validation
 * @profiles If passed, a list of profile names to use for validation constraints
 *
 * @return The validated object or the structure fields that where validated
 * @throws ValidationException
 */
function validateOrFail()

/**
 * Retrieve the application's configured Validation Manager
 */
function getValidationManager()

/**
 * Verify if the target value has a value
 * Checks for nullness or for length if it's a simple value, array, query, struct or object.
 */
boolean function validateHasValue( any targetValue )

/**
 * Check if a value is null or is a simple value and it's empty
 *
 * @targetValue the value to check for nullness/emptyness
 */
boolean function validateIsNullOrEmpty( any targetValue )

/**
 * This method mimics the Java assert() function, where it evaluates the target to a boolean value and it must be true
 * to pass and return a true to you, or throw an `AssertException`
 *
 * @target The tareget to evaluate for being true
 * @message The message to send in the exception
 *
 * @throws AssertException if the target is a false or null value
 * @return True, if the target is a non-null value. If false, then it will throw the `AssertError` exception
 */
boolean function assert( target, message="" )

Delegate Mode

If you are using ColdBox 7, then you can use the Validatable@cbValidation delegate. Which will allow you to add these validation traits to any object you desire.

component delegates="Validatable@cbValidation"{}

The methods delegated by default are the following:

• assert()

• getValidationManager()

• getValidationResults()

• isValid()

• validate()

• validateHasValue()

• validateIsNullOrEmpty()

• validateOrFail()

You can also use the delegation for only certain methods if needed:

// Shorthand Syntax
component delegates="Validatable@cbValidation=validate,validateOrFail"{

}

// Long Syntax via delegate injection
component{

  property name="validatable" 
        inject="Validatable@cbValidation" 
        delegate="validate,validateOrFail"
  
}
