删除“旧”与 saveAll 的关联
我有一个关联问题，即一个“有很多”链接的项目。项目编辑页面包含项目本身的字段和一些关联链接的字段：
echo $form->input('Link.0.url');
echo $form->input('Link.1.url');
echo $form->input('Link.2.url');
在项目控制器中，我使用 $this->Project->saveAll($this->data)，它保存项目和三个关联的链接。美好的。现在，在更新项目时，我希望能够删除一些链接。我想保持简单并使用 jQuery 删除所有 Link.n.* 。不幸的是，这并没有按预期工作：使用 saveAll 后，删除的关联仍然存在，即使它不再在 $this->data 中给出。
CakePHP 在保存关联方面非常具体。遗憾的是我找不到有关删除它们的信息。我希望有人理解我的问题并知道该怎么做。
I have a problem with assocations, i.e. a Project which "hasMany" Links. The project edit page has fields for the Project itself and some for associated Links:
echo $form->input('Link.0.url');
echo $form->input('Link.1.url');
echo $form->input('Link.2.url');
In the Project controller I use $this->Project->saveAll($this->data), which saves the Project and three associated links. Fine. Now while updating Projects I want to be able to delete some links. I want to keep it simple and remove all Link.n.* using jQuery for example. Unfortunately this doesn't work as expected: The removed association still exists after using saveAll, even though it is not given in $this->data anymore.
CakePHP is very specific in saving associations. Sadly I cannot find something about removing them. I hope somebody understands my problem and has an idea what to do.

如果它已经在数据库中，您将需要使用delete()或deleteAll()
if it is already in the database you will need to use delete() or deleteAll()
