在 DBIx::Class 中注入关系

发布于 2024-08-30 05:27:38 字数 419 浏览 2 评论 0原文

我有一些 DBIx::Class::Core 对象，用于对各种数据库表进行建模。

对于其中一些模型（具有“队列”列的模型），我有另一个类注入子对象（基本上，沿着其队列状态“移动”模型对象）。

我还想让该类注入 has_many 关系，

class($name)->has_many('queue_history','MySchema::Result::QueueHistory',
 { 'foreign.record_id'=>'self.id' },
 { where => { type => $name }} );

但我似乎无法正确注册关系（不断收到“没有这样的关系”错误 - 但是，在调用关系方法时来源提供了关系）。

有什么线索表明出了什么问题吗？

I have a handful of DBIx::Class::Core objects that model various database tables.

For some of those models (those that have a 'queue' column), I have another class inject subs (basically, to 'move' the model object along it's queue states).

I'd like to also have that class inject has_many relationships ala

class($name)->has_many('queue_history','MySchema::Result::QueueHistory',
 { 'foreign.record_id'=>'self.id' },
 { where => { type => $name }} );

but I can't seem to get the relationships to register properly (keep getting "No Such Relationship" errors - however, when calling the relationship method on the sources provides back the relationship).

Any clues as to what's wrong?

经过一番研究后，发现以下方法有效：

$class = $schema->class($name)->has_many('queue_history','MySchema::Result::QueueHistory',
 { 'foreign.record_id'=>'self.id' },
 { where => { type => $name }} );

$schema->unregister_source($name);
$schema->register_class($name,$class);

关键是取消注册/注册方法，以便生成通过新的 has_many 关系添加的所有适当的其他方法。

After some digging around, the following works:

$class = $schema->class($name)->has_many('queue_history','MySchema::Result::QueueHistory',
 { 'foreign.record_id'=>'self.id' },
 { where => { type => $name }} );

$schema->unregister_source($name);
$schema->register_class($name,$class);

The key being the unregister/register methods in order to generate all the appropriate other methods that get added by having a new has_many relationship.
