Laravel功能无需返回

Question

在班级Player我有方法：

public function removeFromLineupPrepare()
{
    if (isset($this->team->lineupPrepare) &&$this->lineupPreparePosition) {
        $this->team->lineupPrepare->update([
            $this->lineupPreparePosition => NULL
        ]);
    }
}

当我使用上述方法时：

if ($player->team && $request->team_id != $player->team_id) {
        $player->removeFromLineupPrepare;
}

我收到了一个错误：

Relationship method must return an object of type Illuminate\Database\Eloquent\Relations\Relation

Answer 1

removeFromLineupPrepare是一种方法，但您正在像属性一样访问它。尝试：

$player->removeFromLineupPrepare();
