Node.js 填充没有像我预期的那样工作
请在下面找到我的代码Node.js 填充没有像我预期的那样工作,node.js,mongodb,mongoose,Node.js,Mongodb,Mongoose,请在下面找到我的代码 var mongoose = require('mongoose'); var util = require('util'); var db = mongoose.connect('mongodb://localhost:27017/prats', function(err) { if (err) throw err;} //this does not get printed ); mongoose.connection.on("open", function()
var mongoose = require('mongoose');
var util = require('util');
var db = mongoose.connect('mongodb://localhost:27017/prats', function(err) {
if (err) throw err;} //this does not get printed
);
mongoose.connection.on("open", function(){
console.log("mongodb is connected")} //this gets printed
);
var Schema = mongoose.Schema;
var TestDocumentAccessSchema = new Schema({
documentId: { type: Schema.ObjectId },
userId: { type : String }, // Can be an SSO or a group (DL) id
userName: { type : String },
});
var TestDocumentMasterSchema = new Schema({
documentId: { type: Schema.ObjectId, ref: 'TestDocumentAccess'},
masterId: { type: Schema.ObjectId }
});
var TestDocAccess = mongoose.model('TestDocumentAccess', TestDocumentAccessSchema);
var TestDocMaster = mongoose.model('TestDocumentMaster', TestDocumentMasterSchema);
var document = new TestDocAccess(
{ documentId: '50dc37d6022b2bdd07000004',
userId : "1234",
userName : "Test Name",
}
);
document.save(function (err) {
if (err) return handleError(err);
var master = new TestDocMaster({
documentId: "50dc37d6022b2bdd07000004",
masterId: "50a5e7bcda3c4d557f00847a" // assign an ObjectId
});
master.save(function (err) {
if (err) return handleError(err);
console.log("That's it save success!!....");
TestDocMaster.find({'masterId': '50a5e7bcda3c4d557f00847a'})
.populate('documentId')
.exec(function(err, TestDocAccess) {
//I want all the document row corresponding to the master Id
console.log("=========Test Doc Master======" +util.inspect(TestDocAccess.documentId));
});
});
})
我有多个与主id相对应的documentId,我希望TestDocAccess.documentId中包含所有文档详细信息,但我得到了一个未定义的
请指出上面代码中的错误。对于填充('documentId')
要在您的示例中工作,引用的TestDocAccess
模型集合中必须有一个文档,其id为\u id
(而不是您期望的documentId
)与TestDocMaster
模型集合中的documentId
匹配
