A user has the ability to add languages. languages are stored as an array of type teach or learn in the userschema. I can simply add a language to the languages.teach[] by using push, but how do i remove one?
language object example
let language = {
"code": FR
"level": 1
};
UserScema.js
var UserSchema = new Schema({
email: {
value: {
type: String,
lowercase: true,
//unique: true,
},
token: String,
verified: Boolean,
},
password: {
type: String,
},
phone: {
countryCode: {
type: String,
//required:true,
unique: true,
},
number: {
type: String,
required: true
},
code: String,
verified: {
type: Boolean,
default: false
},
},
jwt: String,
profile: {
username: String,
firstname: String,
lastname: String,
dob: String,
level: Number,
location: String,
image: String,
introduction: String,
},
languages: {
teach: [],
learn: [],
}
},
{
timestamps: {createdAt: 'created_at', updatedAt: 'updated_at'}
});
LanguagesController.js
destroy(req, res) {
let id = req.params.id;
let language = {
"code": req.body.code,
"level": req.body.level
};
let type = req.params.type;
User.findOne({'_id': id}, function (err, user) {
if (err) {
return res.status(404).json({
success: true,
status: 404,
data: err,
message: "User does not exist",
});
}
if (type === "teach") {
for (let i = 0; i < user.languages.teach.length; i++)
if (user.languages.teach[i].code === language.code) {
user.languages.teach[i].remove();
break;
}
}
if (type === "learn") {
//user.languages.learn.push(language);
}
console.log(user);
user.save((err, user) => {
return res.status(200).json({
success: true,
status: 201,
data: user,
message: "Successfully Deleted Language",
});
});
});
}
I tried to use .remove but im getting a user.languages.teach[i].remove is not a function.
user.languages.teach = user.languages.teach.filter( o => o.code !== language.code)instead of your for loop insideif (type === "teach")if (type === "teach")with my above given snippet.
