如何使用PHP activerecord管理关系

我在CodeIgniter中有一个现有的带有HMVC扩展的项目。还可以通过sparc使用php activerecord

对于一个新模块，我创建了两个具有一对多关系的表，直接在DB级别强制执行（在MySQL中）。表格为“nassignment”（PK id）和“nassignment_assignment”（FK assignment_id）

在models下，我创建了两个类'nassignment.php'，分别有类nassignment和类名为nassignment_assignee的'nassignment_assignment.php'

下面是我在controller中尝试的代码

$this->load->model("nassignment");
$nAssignmentArr = $this->nassignment->all();

并得到以下错误

naSignment_.php

class Nassignment_assignee Extends ActiveRecord\Model{
    static $table_name = 'nassignment_assignee';
}

任何建议，为什么它不起作用

请尝试确保文件名与类名匹配，以防万一。看

显然，库也必须按照UCfirst命名约定命名。

我想我可能也有类似的问题。为什么没有人尝试这些问题？

class Nassignment_assignee Extends ActiveRecord\Model{
    static $table_name = 'nassignment_assignee';
}
