Internationalizing model validation messages

In this recipe, we will learn different approaches for the same need: translating model validation messages.

Getting ready

To go through this recipe, we need a basic application skeleton to work with. Go through the previous recipe.

How to do it...

Edit the file article.php located in your app/models folder and make the following changes to the validate property:

public $validate = array(
'title' => array(
'required' => 'notEmpty'
),
'body' => array(
'required' => 'notEmpty'
)
);

There are two ways to have validation messages translated. The first one requires you to override the model constructor by adding the following implementation to the Article class defined in your app/models/article.php file:

public function __construct($id = false, $table = null, $ds = null) {
foreach($this->validate as $field => $rules) {
if (!is_array($rules)) {
$rules = (array) $rules;
}
foreach($rules as $key => $rule) {
if (!is_array($rule)) {
$rules...
