【问题描述】：
背景： 我想使用应该可翻译的 CakePhp 创建一个 Web 应用程序。我想在一个表单中保存同一字段的多个翻译。
问题： 我已经尝试了十几种方法来让它工作，我做到了。但我最终使用了两个自定义 SQL 查询，这真的不像 cakePhp 解决方案。
问题： 有没有人知道达到相同结果的更好方法？
我尝试了什么：
将表单字段命名为“Model.fieldName.locale”之类的名称，这样可以在输入元素的名称 attr 中为其提供正确的格式，但随后我的验证无法识别字段名称。但保存有效。
为表单字段命名为“modelLocale”，并传入名称 attr“data[Model][field][locale]”，在这种情况下，验证适用于 isUnique，但保存到数据库不会不行。
更多变体但不值得一提。
我将在下面添加我的视图和模型：（如果您想查看更多代码或需要更多信息，请询问）
/App/View/Category/add.ctp
<?php echo $this->Form->create(); ?>
<?php echo $this->Form->input('title|dut'); ?>
<?php echo $this->Form->input('title|eng'); ?>

<?php echo $this->Form->input('description|dut', array('type'=>'textarea')); ?>

注意：关于这个主题的信息并不多......我还有很多关于翻译行为的问题，比如在正确的语言环境中获得递归结果，.. . 任何人都知道一个好的 tut 或信息来源（食谱非常有限）
