Question

我有两个数组，第一个包含所有订单，第二个包含我从数据库中获得的拒绝订单

我需要过滤这些订单并根据快照密钥从中删除所有拒绝的订单

所以在运行我的代码之后

尽管我在控制台中测试了我的代码，但我看到了所有订单并包含了被拒绝的命令，它可以正常工作，但在我的React App中不起作用

订单数组

    this.setState({
      orders: orderArr.filter(
        order => !rejectedOrders.some(key => order.snapshotKey === key),
      ),
      loading: false,
    });

为了使代码简短，我将进行过滤

获得订单并将其推送到单独的数组后，我将状态设置为

Const {rejectedOrders}= this.state;
database()
      .ref(
        `Providers/CategoriesOrders/${service ||
          serviceStorage ||
          serviceName}/${uid}`,
      )
      .on('value', snapshot => {
        console.log(snapshot.val());
        let orderArr = [];
        snapshot.forEach(childSnapshot => {
          orderArr.push({
            snapshotKey: childSnapshot.key,
            username: childSnapshot.val().username,
            buildingNumber: childSnapshot.val().buildingNumber,
            service: childSnapshot.val().categoryName,
            date: childSnapshot.val().date,
            time: childSnapshot.val().time,
            description: childSnapshot.val().problemDescription,
            status: childSnapshot.val().status,
            images: childSnapshot.val().Images,
          });
        });
        this.setState({
      orders: orderArr.filter(
        order => !rejectedOrders.some(key => order.snapshotKey === key),
      ),
      loading: false,
    });
      });

但是可惜我得到了三个订单，没有任何过滤！

编辑1

foreach (var ownerToProcess in activeOwnersWithMessageArchiving)
{
    foreach (var extension in extensions)
    {
        using (var db = new SqlConnection(connectionString))
        {
            db.Execute(@"
UPDATE T_MESSAGESTARTER 
   SET Started=@started,Completed=NULL 
 WHERE OwnerId=@ownerId AND ExtensionId=@extensionId;

if @@ROWCOUNT=0
  INSERT INTO T_MESSAGESTARTER (OwnerId,ExtensionId,Started) 
  VALUES (@ownerId,@extensionId,@started)
", new { ownerId = ownerToProcess, extensionId = extension, started = DateTimeOffset.Now });
        }
    }
}

设置状态时我无法过滤数据？
