Trying to get a list of users associated with an event. Here are my eloquent models:
尝试获取与事件关联的用户列表。这是我雄辩的模型:
User.php:
用户.php:
public function fbevents()
{
$this->belongsToMany('Fbevent', 'fbevent_user');
}
Fbevent.php:
Fbevent.php:
public function users()
{
$this->belongsToMany('User', 'fbevent_user);
}
I get this error when I try to find the list:
当我尝试查找列表时出现此错误:
$event = Fbevent::find(10);
var_dump($event->users->lists('userId'));
I've set up a pivot table in the db with the following migration:
我已经通过以下迁移在数据库中设置了一个数据透视表:
$table->increments('id');
$table->integer('fbevent_id')->unsigned()->index();
$table->foreign('fbevent_id')->references('id')->on('fbevents')->onDelete('cascade');
$table->integer('user_id')->unsigned()->index();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
$table->timestamps();
And added an entry in the fbevent_user table with fbevent_id = 10 and user_id = 1.
并在 fbevent_user 表中添加了一个条目,其中 fbevent_id = 10 和 user_id = 1。

You need to return a result from your relations
你需要从你的关系中返回一个结果
public function fbevents()
{
return $this->belongsToMany('Fbevent', 'fbevent_user');
}
public function users()
{
return $this->belongsToMany('User', 'fbevent_user');
}
