我正在处理一个node js项目,在那里我得到了以下错误:
CastError: Cast to ObjectId failed for value "[ [ '63e8e6e8b8a285d68b1fbd0c', '63e9951ded54221a516fc622' ] ]" (type Array) at path "labels" because of "BSONTypeError"

}
我有两个文档,一个是问题,另一个是标签。问题与标签模式有一对多的关系。因此,我的标签模式如下所示
labels:[{
type:mongoose.Schema.Types.ObjectId,
ref:'Label'
}],
问题是,当我使用此代码在标签中插入单个值时,不会收到错误
issues.labels.push(allLabelsWithId);
这里allLabelsWithId是一个数组。但是当这个数组的值大于1时,它会失败并给予上面提到的错误。
我需要传递多个值,那么正确的方法是什么呢?

尝试:

对于多个值,
$each
运算符是一种解决方案
