我有事件模型,并希望能够选择其中的其他事件以显示在前端。
我首先尝试的是关系,但是问题是我不知道如何使用数据透视表,因为实际上,它应该包含两个字段,并且都应该命名为“ event_id”,这显然是不可能的。 也许有人可以建议任何避免这种情况的方法,或者是通过事件模型中的事件选择字段解决我的问题的更好方法?
谢谢。

是的,same name for relation_id
是不可能的,但是我们可以选择:)
您可以像这样创建中间表
<?php namespace HardikSatasiya\SoTest\Updates;
use Schema;
use October\Rain\Database\Updates\Migration;
class BuilderTableCreateHardiksatasiyaSotestEventsEvents extends Migration
{
public function up()
{
Schema::create('hardiksatasiya_sotest_events_events', function($table)
{
$table->engine = 'InnoDB';
$table->increments('id')->unsigned();
$table->integer('events_id')->unsigned();
$table->integer('related_events_id')->unsigned();
});
}
public function down()
{
Schema::dropIfExists('hardiksatasiya_sotest_events_events');
}
}
然后,我们只需要添加带有适当选项的关系
public $belongsToMany =[
'skills' => [
'HardikSatasiya\SoTest\Models\Skills',
'table' => 'hardiksatasiya_sotest_events_skills',
'order' => 'title'
],
'related_events' => [
'HardikSatasiya\SoTest\Models\Events',
'table' => 'hardiksatasiya_sotest_events_events',
'order' => 'title',
'key' => 'events_id',
'otherKey' => 'related_events_id'
]
];
我们指定对于此关系,
event_id
用于主事件,related_events_id
用于其他事件,我们将其添加为相关事件。config_relation.yaml
<-将位于事件控制器视图文件夹中。

related_events:
label: Events
type: partial
path: $/hardiksatasiya/sotest/controllers/events/_related_events.htm
现在为部分
_related_events.htm
<?= $this->relationRender('related_events') ?>
结果
使用代码访问
use HardikSatasiya\SoTest\Models\Events as EventsModel;
function onStart() {
$this['event'] = $event = EventsModel::first();
dd($event->related_events);
}
