[英]node.js mongoose find() method usage with key value in object
I'd like to find data from mongodb using find() function Here is my schema我想使用 find() 函数从 mongodb 中查找数据这是我的架构
const newcontractSchema = mongoose.Schema({
creator: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User',
required: false,
index: true,
},
status: {type: String, required: false, default: 'init'},
a_status: {type: String, required: false, default: 'pending'},
contractInfo: {
startDate: {type: Date},
endDate: {type: Date},
expectedUsage: {type: Number, default: 2000},
provider: {type: Object},
rate: {type: Number},
term: {type: Number},
userid: {type: String}
}, {timestamps: true});
and what I tried is我试过的是
Newcontract.find({contractInfo: {userid: {$eq: req.body.userid}}})
But I couldn't fetch data based on this userid in contractInfo object但是我无法根据 contractInfo 对象中的这个用户 ID 获取数据
How to do it?怎么做?
Thanks谢谢
You are not querying correctly.您没有正确查询。
You need something like this:你需要这样的东西:
db.collection.find({
"contractInfo.userid": "yourid"
})
Mongo playground example here Mongo 游乐场示例在这里
In mongoose
will be very similar:在
mongoose
中将非常相似:
Newcontract.findOne({
"contractInfo.userid": req.body.id
})
Note that you can use findOne()
to get only one object if you want.请注意,如果需要,您可以使用
findOne()
仅获取一个对象。
