如何更改CakePHP 3.x验证错误消息

Question

Here is validation function in CakePHP 3.x for PostsTable :

public function validationDefault(Validator $validator)
{
    $validator
        ->add('id', 'valid', ['rule' => 'numeric'])
        ->allowEmpty('id', 'create');

    $validator
        ->requirePresence('title', 'create')
        ->notEmpty('title','Please fill Title field');

    $validator
        ->requirePresence('content', 'create')
        ->notEmpty('content','Please add a Content');

    return $validator;
}

The form in add view is:

<?= $this->Form->create($post) ?>
<fieldset>
    <legend><?= __('Add Post') ?></legend>
    <?php
        echo $this->Form->input('title');
        echo $this->Form->input('content');
        echo $this->Form->input('category_id', ['options' => $categories]);
    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

Why is the default validation message always shown instead of the notEmpty message?

问题已解决，我将validationDefault(Validator $validator)重命名为validationPost(Validator $validator) ，我也在PostsController内部进行了此修改，增加了功能：

$post = $this->Posts->patchEntity($post, $this->request->data,['validate' => 'Post']);
