I have two schemas defined, imageSchema and userSchema. imageSchema has key postedBy: userSchema. Question is shall I remove unused attributes of userSchema (like password) when nested into imageSchema, if so how to do it?
var userSchema = new mongoose.Schema({
email: String,
password: String,
name: String,
}, {versionKey: false})
var imageSchema = new mongoose.Schema({
filePath: String,
user: userSchema,
createdAt: Date,
comments: [{body: "String", by: mongoose.Schema.Types.ObjectId}]
})
...
app.post("/upload-image", async function(req, res){
if(req.session.user_id) {
...
fileSystem.rename(oldPath, newPath, function(err2){
getUser(req.session.user_id, function(user){
delete user.password
var currentTime = new Date().getTime()
Image.create({
"filePath": newPath,
"user": user,
"createdAt": currentTime,
"comments": []
}, function(err2, data){
res.redirect("/?message=image_uploaded")
})
...
So after I created a new document of Image, I checked the database, the user field of the new Image has the attribute of password, which is not desired. "delete user.password" seems not working. How should I delete this attribute? Shall I do it when defining the imageSchema, or remove it when posting the data (the app.post part)?
This can be done is multiple ways. The way i like is to exclude the field from schema and also exclude while insertion.
var imageSchema = new mongoose.Schema({
filePath: String,
user: userSchema.pick(["email", "name"]), // this will return schema with only email and name from the schema
createdAt: Date,
comments: [{body: "String", by: mongoose.Schema.Types.ObjectId}]
})
we are omitting the user here before insertion
this can be also done with underscore/lodash _.omit(user, 'password')
getUser(req.session.user_id, function({password, ...user}){
Image.create({
"filePath": newPath,
"user": user,
"createdAt": Date.now(),
"comments": []
})
}
