node.js - Lowdb - 将数据插入另一个数组内的数组中

Question

我基本上试图为每个用户做一个 list ，为此我使用了 Lowdb帮我处理数据。
我现在的结构是这样的:

 {
  "users": [
    {
    "id": "450453034724491266",
    "tag": "Briggs#4992",
    "inventory": [
      {"itemID": "1320488779", "rarity": "rare"},
      {"itemID": "1674364779", "rarity": "common"},
    ]
  },
    {
     "id": "272659147974115328",
     "tag": "Zytekaron#0572",
     "inventory": [
      {"itemID": "1320488779", "rarity": "rare"},
      {"itemID": "1674364779", "rarity": "common"},
     ]
    }
  ]
}

我想到的是

//get 'users', find the id and then write inside the inventory array (which i dont know how to)
db.get('users')
.find({ id: 'id' })

Answer 1

测试了这个代码片段，它工作得很好。

// Get your user
let inventory = db
    .get('users')
    .find({ id: '272659147974115328' })
    .get('inventory')
    .value();

// Do something to your user's inventory
inventory.push({ itemID: '9999999', rarity: 'common' });

// Update the user with the modified inventory

db.get('users')
    .find({ id: '272659147974115328' })
    .assign({ inventory })
    .write();
