用户体验 向用户呈现项目，用户喜欢该项目，因此他将该项目保存到他的项目中 保存的项目。用户意图是成为此类项目的一部分。
程序员目标： 我打算在用户和项目之间使用一个连接表作为检索相关数据的方法。此连接表应用作两个模型之间的链接。用户发布的项目以及用户所属的项目（用户感兴趣并希望保存的其他项目，或者是其中的一部分）显然是多对多关系。
问题： 单击按钮（保存按钮）后，用户应该能够通过简单地更新连接表或添加关联来保存此项目，例如用户45与项目8900相关联。
当我尝试通过User模型更新连接表时，它不会保存数据。
答案 0 :(得分：1)
每次我设置HABTM关系时，我都会为连接表创建一个模型（例如UsersProject），然后设置这样的关系：
User hasMany UsersProject
UsersProject belongsTo User, Project
Project hasMany UsersProject.
然后你的saveProject函数实际上应该
$this->User->UsersProject->save($this->data)
当然，您还需要为连接关系创建适当的数据库表。
以下是在Cakephp 1.3中设置HABTM的参考资料。对不起，我没有2.x的经验，但我认为这是相同的概念。
