CakePHP 3.0.8 翻译行为和数据验证(requirePresence，notEmpty)

In order to actually apply validation and/or application rules, and have them recognized in forms, you'll have use a custom translation table class that holds the rules, and you must use the actual property name that the translate behavior uses for the hasMany associated translation table, which is _i18n.

这是一个例子.

src/Model/Table/IngredientsI18nTable.php

namespace AppModelTable;

use CakeDatasourceEntityInterface;
use CakeORMRulesChecker;
use CakeORMTable;
use CakeValidationValidator;

class IngredientsI18nTable extends Table
{
    public function initialize(array $config) {
        $this->entityClass('Ingredient');
        $this->table('i18n');
        $this->displayField('id');
        $this->primaryKey('id');
    }

    public function validationDefault(Validator $validator) {

        $validator
            ->allowEmpty('name')
            ->add('name', 'valid', [
                'rule' => function ($value, $context) {
                    return false;
                }
            ]);
        return $validator;
    }

    public function buildRules(RulesChecker $rules)
    {
        $rules->add(
            function (EntityInterface $entity, $options) {
                return false;
            },
            'i18nName',
            [
                'errorField' => 'name'
            ]
        );

        return $rules;
    }
}

配料表

public function initialize(array $config) {
    // ...

    $this->addBehavior('Translate', [
        // ...
        'translationTable' => 'IngredientsI18n'
    ]);
}

查看模板

echo $this->Form->hidden('_i18n.0.locale', ['value' => 'fr_FR']);
echo $this->Form->input('_i18n.0.name');

echo $this->Form->hidden('_i18n.1.locale', ['value' => 'da_DK']);
echo $this->Form->input('_i18n.1.name');

// ...

现在这些字段将选择正确的验证器，因此不会被标记为必需的.在创建/修补实体时也将应用验证，最后也将应用应用程序规则.但是我不能保证这没有任何副作用，因为内部的翻译行为似乎没有考虑到 _i18n 属性已在外部设置的情况！

foreach ($this->request->data['_i18n'] as $translation) {
    $ingredient->translation($translation['locale'])->set('name', $translation['name']);
}
