我能够做到
db.getCollection('comps').find({"stats.cat3.detail.name" : "Friendlyness"})`
这显示了详细数组中名称为“Friendlyness”的正确文档。
我想将“友善”改为“友善”
我试过了：
db.getCollection('comps').update(
{"stats.cat3.detail.name" : "Friendlyness"},
{$set : {"stats.cat3.detail.name" : "Friendliness"} }
)
并且出现了类似的错误 “不能使用部分（stats.cat3.detail.name的统计数据）来遍历元素（{stats：[{cat3：....”
我尝试在更新对象属性中放置位置运算符“$”。但仍然会出错。
