Mongoose嵌入式文档不保存

对于任何玩“激战2”的人来说，这个模式可能看起来很熟悉。我试图通过他们的API下载所有项目，并且无法获取嵌入的“细节”属性以编组和/或持续。这是我用猫鼬首次尝试，所以我希望这里有一个昭然若揭的问题：Mongoose嵌入式文档不保存

这里是我的架构定义：

var ItemSchema = new Schema({ 
    _id: Number, 
    name: String, 
    icon: String, 
    description: String, 
    type: String, 
    rarity: String, 
    level: Number, 
    vendor_value: Number, 
    default_skin: Number, 
    flags: [String], 
    game_types: [String], 
    restrictions: [String], 
    details: {    // This is the problem property 
     type: String, 
     weight_class: String, 
     defense: Number, 
     infusion_slots: { 
      flags: [String], 
      item_id: Number 
     }, 
     infix_upgrade: { 
      attributes: [{ 
       attribute: String, 
       modifier: Number 
      }], 
      buff: { 
       skill_id: String, 
       description: String 
      } 
     }, 
     suffix_item_id: Number, 
     size: Number, 
     no_sell_or_sort: Boolean, 
     description: String, 
     duration_ms: Number, 
     unlock_type: String, 
     color_id: Number, 
     recipe_id: Number, 
     charges: Number, 
     flags: [String], 
     infusion_upgrade_flags: [String], 
     suffix: String, 
     bonuses: [String], 
     damage_type: String, 
     min_power: Number, 
     max_power: Number 
    } 
});

我试图通过两个插入保存传入对象和findOneAndUpdate（upsert）。

var gwItem = // grab from API. 
Item.remove({_id: gwItem.id}).exec(); 
// At this point, details looks like an object property. 
gwItem['_id'] = gwItem.id; 
var item = new Item(gwItem); 
// At this point, calling item.toObject() shows no 'details' property set... 
item.save().exec(); // 'details' not saved here 
// Do below in replacement of item.save(); 
gwItem['$setOnInsert'] = {_id: gwItem.id}; 
// This saves 'details' property with a value of '[object Object]'... 
Item.findOneAndUpdate({_id: gwItem.id}, gwItem, {upsert:true}, function(){});

什么样的API发送和填充到“gwItem”上面的代码示例：https://api.guildwars2.com/v2/items/68743

我在做什么错？

这是因为Mongoose如何定义模式。由于您使用关键字type作为details的路径名，因此它将details定义为String字段，其余路径为details的选项。只需将type: String更改为type: {type: String}，即可完成设置。更多信息here。
