我想做的是创建一个新集合,并将该集合推入特定的User.collections数组中。我读过许多stackoverflow帖子,他们都说使用User.update()或User.findOneAndUpdate()。我也没有运气。我可以创建一个Collection并将其保存到mongo,所以我知道我确实在访问数据库。这是我的代码,如果有谁可以帮忙,我将不胜感激。
用户架构
const mongoose = require('mongoose');
const { Schema } = mongoose;
const userSchema = new Schema({
googleID: String,
givenName: String,
familyName: String,
collections: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "collection"
}
]
});
mongoose.model('users', userSchema);
集合模式:
const mongoose = require('mongoose');
const { Schema } = mongoose;
const collectionSchema = new Schema({
type: String,
name: String,
gamesCollected: [
{
id: Number
}
]
});
mongoose.model('collection', collectionSchema);
我的路线:
router.get('/get_collection', (req, res) => {
const collection = new Collection({
type: 'SNES',
name: 'First SNES Collection',
gamesCollected: [{ id: 5353 }]
}).save();
User.update({googleID: req.user.googleID}, {$push: {collections: collection}});
});

Save不是同步操作,而是异步操作,因此您需要使用promise返回并处理它,一旦完成,就更新用户模型。这些行中的一些内容:
router.get('/get_collection', async (req, res) => {
let collection = new Collection({
type: 'SNES',
name: 'First SNES Collection',
gamesCollected: [{ id: 5353 }]
})
await collection.save().exec();
await User.update(
{googleID: req.user.googleID},
{$push: {collections: collection._id}}
).exec();
});
