我正在玩CakePHP框架及其烘焙方法。所以，首先我创建了一个数据库，然后我开始烘焙 - 结果几乎完美。
所以，我有3个表：users，projects和project_helper。 前两个表是标准表，即：
用户：
用户：
问题是一个项目可以属于许多用户，每个用户可以有很多项目。为了避免制作新栏目＆＃34;项目＆＃34;在用户表中并在字符串（2,6,11,77）中保存项目id并在以后将它们扩展到数组中我决定创建另一个包含两个主键（两列）的表。
Project_helper：
它有点工作，我可以列出属于指定用户等的所有项目。
但是，由于这些表之间没有真正的关联，我无法将用户分配给项目（除非我在db中手动添加它们）。
Project_helper 表引用了用户＆amp;项目，但用户和项目都没有引用project_helper或彼此。
据我了解，我通过创建project_helper表创建了多对多的关系，如果我从这个tut中正确地学到了： http://www.phpknowhow.com/mysql/many-to-many-relationships/ 我做得对，其余的工作都是由查询管理的。
我想要实现的是，在创建新项目时，必须至少分配一个用户（稍后，当有一个登录系统时，它将成为项目的创建者作为其第一个成员，但现在它没有＆＃ 39;我想是的。）
应该有一个下拉输入来选择用户并将其分配给该项目。 第三个表（projects_helper）没有控制器或视图或其他内容。我希望没有必要制作一个。
我是否对db做错了，可以自动生成（烘焙）吗？

干杯。
编辑。 正如我在想的那样，我可以添加一个＆＃39;作者＆＃39;列到项目表，因此创建项目的用户将自动成为其作者。但是，它仍然没有解决将其他用户分配给项目的问题。我希望通过项目控制器和工作完成它。项目添加/编辑视图。
