我有点泡菜。每当我以登录用户身份创建新的简历时,都不会将简历ID添加为数组。即[[20293],“ 2932392”,“ 32903239”]
相反,它将覆盖用户架构中的当前简历ID。这是代码
用户架构
const UserSchema = new Schema({
_vId: {
type: String,
default: id.generate()
},
firstName: {
type: String,
required: true
},
lastName: {
type: String,
required: true
},
accountType: {
type: String,
enum: ['Alphaneer', 'Administrator', 'Support', 'PRO'],
default: 'Alphaneer'
},
email: {
type: String,
required: true,
trim: true
},
username: {
type: String,
required: true,
trim: true,
unique: true
},
bio: {
type: String,
default: "No bio provided."
},
// TODO: Hash the password before inserting as a document :)
password: {
type: String,
required: true
},
createdAt: {
type: String,
default: moment(new Date()).format("MMM DD, YYYY") // "Sun, 3PM 17"
},
resume: [ { type: mongoose.Schema.ObjectId, ref: "Resume" } ]
});
我在哪里发布我的简历
// POST /dashboard/resume/create
router.post('/resume/create', (req, res, next) => {
Resume.create(req.body, (err, resume) => {
if (err) {
var err = new Error("Error:" + err);
err.status = 404;
next(err);
} else {
req.user = jwtDecode.decode(req.session.tokenID, 'secret');
//I am assuming that you have saved your resume and getting the saved object in `resume`, now update the logged in user in req.user
var user = req.user.sessionId;
var updateData = {
resume: resume._id
}
//save the updated user
User.findByIdAndUpdate(user, updateData, function(err, user) {
console.log(user);
if (err) {
res.json(err);
} else {
res.json(user);
}
})
}
})
});

更新的代码:
// POST /dashboard/resume/create
router.post('/resume/create', (req, res, next) => {
Resume.create(req.body, (err, resume) => {
if (err) {
var err = new Error("Error:" + err);
err.status = 404;
next(err);
} else {
req.user = jwtDecode.decode(req.session.tokenID, 'secret');
//I am assuming that you have saved your resume and getting the saved object in `resume`, now update the logged in user in req.user
var user = req.user.sessionId;
var updateData = {
resume: resume._id
}
//save the updated user
User.findById(user, function(err, user) {
console.log(user);
if (err) {
res.json(err);
} else {
user.resume.push(resume.id)
user.save(function(user) {
return res.json(user);
});
}
})
}
})
});
最佳答案
这是错误的:
var user = req.user.sessionId;
var updateData = {
resume: resume._id
}
//save the updated user
User.findByIdAndUpdate(user, updateData, function(err, user) {
console.log(user);
if (err) {
res.json(err);
} else {
res.json(user);
}
});
resume
字段是一个数组,您将其作为字符串字段进行操作。方法findOneAndUpdate
做两件事:通过ID查找文档
用新数据更新
第二个参数是要设置的新数据。因此,第二步翻译为:
User.upate({ _id: user }, { resume: resume._id });
你看到什么问题了吗?
resume
必须存储一个简历ID数组,您正在将ID设置为值。显然,这将引发MongooseError。您的第二张照片是正确的,但有错字:
User.findById(user, function(err, user) {
console.log(user);
if (err) {
res.json(err);
} else {
user.resume.push(resume.id)
user.save(function(user) {
return res.json(user);
});
}
});
您必须添加
_id
字段,因为这是新创建的文档(恢复)的ObjectID。因此,您需要改为执行user.resume.push(resume._id)
。更新资料
根据您的最新评论,您想填充用户模型,即通过关联ID检索所有模型数据。在这种情况下,建议对resumes数组进行如下更改:
...
resumes: [
{
resume: {
type: Schema.Types.ObjectId,
ref: 'Resume'
}
}
]
要用所有Resume数据填充用户文档,您只需要引用
resume
字段数组中的resumes
键。User.findById(user, function(err, user) {
if (err) {
return res.json({ success: false, message: err.message });
}
user.resume.push(resume.id)
user.save(function(err, user) {
if (err) {
return res.json({ success: false, message: err.message });
}
// save was fine, finally return the user document populated
User.findById(user).populate('resumes.resume').exec(function(err, u) {
return res.json(u);
});
});
}
});
populate
方法接受一个字符串,其中包含我们要用其填充模型数据的字段。您的情况是唯一字段(resume
)。运行查询后,您将获得以下内容:{
_id: a939v0240mf0205jf48ut84sdfdjg4,
...,
resumes: [
resume: {
_id: f940tndfq4ut84jofgh03ut85dg9454g,
title: 'Some title'
},
...
]
}
