php - symfony 插入多行而不是一行

Question

我这里有一个有线的情况。在持久化 symfony 插入多个记录而不是一个。我找不到我的代码有任何问题，而且我不确定如何调试此错误，因为它看起来一切正常。

应用程序背后的逻辑是用户可以选择两个公交车站并创建路线。他还需要定义价格和组(最少和最多人数)。此外，用户需要选择将行驶这条特定路线的公交车辆

有人知道问题出在哪里吗？

这是提交表单时实体的输出

StationStandardPrice {#553 ▼
  -id: null
  -company: Company {#549 ▶}
  -busVehicleGroupSize: BusVehicleGroupSize {#1233 ▶}
  -departureStation: Stations {#1247 ▶}
  -destinationStation: Stations {#1236 ▶}
  -currency: Currencies {#1015 ▶ …2}
  -price: 99.0
  -busVehicles: ArrayCollection {#554 ▼
    -elements: array:2 [▼
      0 => BusVehicle {#1023 ▶}
      1 => BusVehicle {#1208 ▶}
    ]
  }
}

这是路线的实体(简化版)

问题似乎出在:

public function addBusVehicles(BusVehicle $busVehicles)
{
    if ($this->busVehicles->contains($busVehicles)) {
        return;
    }
    $this->busVehicles->add($busVehicles);
    $busVehicles->addBusVehicleGroup($this);
}

什么时候打电话

$busVehicles->addBusVehicleGroup($this);
