Laravel雄辩的多态一对一？

问题描述

我正在尝试设置一个多态的一对一关系（多态等效的has_one和belongs_to）。我有一个地址模型，那里是其他几个我想要一个地址的模型。但是，我对文档的措辞感到困惑。我看过 morphMany 方法，但我的问题是：我应该使用 morphMany ，即使我只想有一个地址，还是有什么东西像 morphOne 方法我应该使用？

I'm trying to setup a polymorphic one-to-one relationship (the polymorphic equivalent of has_one and belongs_to).I've got an Address model, and there are several other models that I want to have one address. However, I'm confused by the wording of the docs. I've seen the morphMany method, but my question is: should I use morphMany even though I only want it to have one address, or is there something like a morphOne method I should be using?

编辑：我的地址模型有这些字段，只是为了帮助可视化：

My Address model has these fields, just to help visualize:

Schema::create('addresses', function ($table)
{
    $table->increments('id');
    $table->string('street');
    $table->string('street_more')->nullable();
    $table->string('city');
    $table->string('state')->nullable();
    $table->string('country');
    $table->string('postal_code');
    $table->integer('addressable_id');
    $table->string('addressable_type');
});

推荐答案

是的，有一个 morphOne 方法，我认为这是你应该使用的这种情况：。

还可以使用

$table->morphs('addressable');

而不是

$table->integer('addressable_id');
$table->string('addressable_type');

我在L4的自定义包中使用了morphOne，效果很好。

I've used morphOne in a custom package for L4 and works pretty well.
