Kohana ORM 关系
我有几个表并为它们定义了关系。
{Table Department} {Table Unit} {Table Branch}
一个部门可以有多个分支机构，一个分支机构只能属于一个部门。我需要能够获取部门名称、部门 ID、分支名称
Branch has an instance of departmentid in it.
如何在一次 ORM 调用中提取这些信息？
class Model_Admin_Departments extends ORM
{
protected $_has_many = array('branches' => array ());
class Model_Admin_Branches extends ORM
{ protected $_belongs_to = array('部门' => array());
我还在数据库端创建了外键约束，并在删除时使用级联操作。这会导致问题吗？还是没关系？
I have a couple of tables and have defined relationships for them.
{Table Department} {Table Unit} {Table Branch}
A Department can have more than one branch, a branch can only belong to one department. I need to be able to get the department name, departmentid, branchname
Branch has an instance of departmentid in it.
How do I pull this in one ORM call?
class Model_Admin_Departments extends ORM
{
protected $_has_many = array('branches' => array ());
class Model_Admin_Branches extends ORM
{
protected $_belongs_to = array('departments ' => array());
I have also created the foreign key constraints on the db side with action cascade on delete. Could this cause problems or that is fine?

假设您拥有正确的声明的关系，您应该能够使用
with(...)方法。Assuming you have the right relationships declared you should be able to use the
with(...)method on your ORM object.
