New to Javascript, trying to print the function in the output using console.log.
var shopperObject = {
isMale: true,
age: 29,
firstName: "Dean",
lastName: "Wilcoxson",
preferredNickName: "Deanoe",
birthDate: "07/28/1991",
driversLicenseNumber: "E3874612",
groceryList: ["Apples", "Steak", "Milk", "Bread", "Cheddar_Cheese", ],
fullName: function() {
return this.firstName + " " + this.lastName;
}
};
console.log(shopperObject.fullName);
//output
[Function: fullName]
Try this shopperObject.fullName()
var shopperObject = {
isMale: true,
age: 29,
firstName: "Dean",
lastName: "Wilcoxson",
preferredNickName: "Deanoe",
birthDate: "07/28/1991",
driversLicenseNumber: "E3874612",
groceryList: ["Apples", "Steak", "Milk", "Bread", "Cheddar_Cheese", ],
fullName: function() {
return this.firstName + " " + this.lastName;
}
};
console.log(shopperObject.fullName());

I have a service function to get users from my MySQL database using Sequelize ORM and i would to like to append fullName to the Users.
const filterUsers = async ([...users]:IUsers[]) => {
let searchAttributes = {};
if (users) { searchAttributes = { [Op.or]: users }; }
const filteredUsers = await User.findAll({
raw: true,
nest: true,
where: { ...searchAttributes },
include: [{
model: Club,
as: 'homeClub',
}, {
model: Club,
as: 'awayClub',
}] });
return filteredUsers as unknown as IUsersWithTeams[];
};
FilteredUsers response:
filteredUsers =
[
{
id: 1
name: 'John',
LastName: 'Mayer',
homeClub: 'Barcelona',
awayClub: 'Real Madrid',
},
{
id: 2,
name: 'Adam',
LastName: 'Smith',
homeClub: 'PSG',
awayClub: 'Milan',
},
]
What i would like to receive:
const expectedUserResponse = [
{
id: 1
name: 'John',
LastName: 'Mayer',
FullName: 'John Mayer',
homeClub: 'Barcelona',
awayClub: 'Real Madrid',
},
{
id: 2,
name: 'Adam',
LastName: 'Smith',
FullName: 'Adam Smith',
homeClub: 'PSG',
awayClub: 'Milan',
},
]
How can i do that ? Thank you very much if you can help me ;)
You need to use a virtual field, see documentation and my other answer to the similar question. It seems the official documentation has the example that perfectly fits your request:
const { DataTypes } = require('#sequelize/core');
const User = sequelize.define('user', {
firstName: DataTypes.TEXT,
lastName: DataTypes.TEXT,
fullName: {
type: DataTypes.VIRTUAL,
get() {
return `${this.firstName} ${this.lastName}`;
},
set(value) {
throw new Error('Do not try to set the `fullName` value!');
}
}
});
I would like to display some information about members, but I don't know how to resolve array of field 'time'. This is array, because it shows their login time. What should I do?
I used GraphQLString, but I am aware of this bad solution.
So I'm getting an error:
"message": "String cannot represent value: [\"12:08\"]",
Here is schema.js
const axios = require("axios");
const {
GraphQLObjectType,
GraphQLString,
GraphQLList,
GraphQLSchema
} = require("graphql");
const memberType = new GraphQLObjectType({
name: "Member",
fields: () => ({
nick: {
type: GraphQLString
},
name_and_surname: {
type: GraphQLString
},
time: {
type: GraphQLString
}
})
});
//Root Query
const RootQuery = new GraphQLObjectType({
name: "RootQueryType",
fields: {
users: {
type: new GraphQLList(memberType),
description: "List of members",
resolve(parent, args) {
return axios
.get("http://25.98.140.121:5000/data")
.then(res => res.data);
}
}
}
})
module.exports = new GraphQLSchema({
query: RootQuery
});
And here is JSON
[
{
"time": [
"12:08"
],
"nick": "Cogi12",
"name_and_surname: "John Steps"
},
{
"time": [
"12:16"
],
"nick": "haris22",
"name_and_surname": "Kenny Jobs"
},
{
"time": [
"12:07",
"12:08",
"12:17",
"12:19",
"12:45",
"13:25"
],
"nick": "Wonski",
"name_and_surname": "Mathew Oxford"
}
]
you can use GraphQLList along with GraphQLString for time type like this,
const memberType = new GraphQLObjectType({
name: "Member",
fields: () => ({
nick: {
type: GraphQLString
},
name_and_surname: {
type: GraphQLString
},
time: {
type: new GraphQLList(GraphQLString)
}
})
});

console.log("user data: " + res.companies.orgNo);
},
error => {
console.log(error);
},
() => {
}
);
}
Output
Result
main res: [object Object]
Name: undefined
companyid: 28764
companies: [object Object]
token: lkjdfjsgosdfjuguerujgoiehjiughdskjge9r8w
user data: undefined
user data: undefined
user data: undefined
Json Response example:
{
"user": {
"id": 123456,
"company_id": "28764",
"name": "TEST",
"email": "test#dummy.com",
"mobile": "91273493412412",
"locale": "en",
"companies": [
{
"companyId": "idww",
"name": "nameww",
"orgNo": "orgww",
"roles": [
{
"role": "Admin"
},
{
"role": "Guest"
}
],
"services": []
},
{
"companyId": "idqq",
"name": "nameqq",
"orgNo": "orgqq",
"roles": [
{
"role": "Admin"
},
{
"role": "Guest"
}
],
"services": []
},
],
},
"token": "lkjdfjsgosdfjuguerujgoiehjiughdskjge9r8w",
"currentCompanyID": "28764"
}
I want to get:
token,
companyid,
user -> name,
user -> companies array
The question is basically what is the best way (best practice) to handle many array in a json file in Angular 2+? As you can see with my output I'm only getting companyid and token data, and not getting companies array or user data.
Create Role Model:
export class Role{
id: number;
name: string;
constructor(attrs: any = null) {
if (attrs) {
this.build(attrs);
}
}
build(attrs: any): void {
this.id = attrs.id;
this.name = attrs.name;
}
}
Create Company Model:
export class Company{
id: number;
name: string;
roles: Array<Role>;
services: any;
constructor(attrs: any = null) {
if (attrs) {
this.build(attrs);
}
}
build(attrs: any): void {
this.id = attrs.id;
this.name = attrs.name;
this.services = attrs.services;
if(attrs.roles) {
this.roles = attrs.roles.map(
r => new Role(r)
);
}
}
}
Create User Model:
export class User{
id: number;
name: string;
email: string;
companies: Array<Company>;
constructor(attrs: any = null) {
if (attrs) {
this.build(attrs);
}
}
build(attrs: any): void {
this.id = attrs.id;
this.name = attrs.name;
this.email = attrs.email;
if(attrs.companies) {
this.companies = attrs.companies.map(
c => new Company(c)
);
}
}
}
By doing so, you create entities automatically. According to your Json Response example, you need to create another model. Let's call it Data!
export class Data{
user: User;
token: string;
currentCompanyID: string;
constructor(attrs: any = null) {
if (attrs) {
this.build(attrs);
}
}
build(attrs: any): void {
this.currentCompanyID = attrs.currentCompanyID;
this.token = attrs.token;
this.user = attrs.user;
}
}
Retrieve data from sample service method like this:
getData(): Observable<any>{
return this.http
.get('awesome_url')
.map((data: any) => new Data(data));
}
Hope I help!
This is my req.body json data from angularjs controller:
{
phoneno: [
{ id: 1, gsm: '123457801', firstName: 'Mohamed', lastName: 'Sameer'},
{ id: 2, gsm: '123450987', firstName: 'Hameed', lastName: 'Basha' }
],
sender: 'ifelse',
message: 'Hello Test'
}
i want to get gsm values from req.body
I want to make the above structure into this type:
[{phoneno:123457801;sender:'ifelse';message:'Hello Test'},{phoneno:123450987;sender:ifelse;message:'Hello Test'}]
then only i am able to insert in mysql.
I think it will helpful to you!...
var body={
phoneno: [
{ id: 1, gsm: '123457801', firstName: 'Mohamed', lastName: 'Sameer'},
{ id: 2, gsm: '123450987', firstName: 'Hameed', lastName: 'Basha' }
],
sender: 'ifelse',
message: 'Hello Test'
};
var new_req_body=[];
for(var i=0;i<body.phoneno.length;i++){
var new_arr={
sender:body.sender,
message:body.message,
phoneno:body.phoneno[i].gsm
};
new_req_body.push(new_arr);
}
console.log(new_req_body);
I have a function which needs to be implemented with Bluebird Promises but unable to work it out. Here is a pseudo code
exports.addEmployees=function (req,res){
var data = [
{
firstName: 'XXXXX',
lastName: 'V',
phone: '9999999999',
dateOfBirth: '2010-08-02',
department: 'IT',
startDate: '2015-08-02',
created: now,
updated: now
},
{
firstName: 'YYYYY',
lastName: 'K',
phone: '8888888888',
dateOfBirth: '2011-08-02',
department: 'IT',
startDate: '2015-08-02',
created: now,
updated: now
},
];
async.each(data, function(item,callback){
req.db.Employee.create(item, callback);
},function(err){
if(err){
res.send("Error!");
}
res.send("Success!");
}
);
}
Thanks
Something like
var Promise = require("bluebird")
var data = [
{
firstName: 'XXXXX',
lastName: 'V',
phone: '9999999999',
dateOfBirth: '2010-08-02',
department: 'IT',
startDate: '2015-08-02',
created: now,
updated: now
},
{
firstName: 'YYYYY',
lastName: 'K',
phone: '8888888888',
dateOfBirth: '2011-08-02',
department: 'IT',
startDate: '2015-08-02',
created: now,
updated: now
},
];
Promise.map(data, function(item) {
return req.db.Employee.create(item)
.then(function(id){ return id })
.catch(MyError, function(e) {
e.item = item;
throw e;
})
}).then(function(idList) {
res.send("Success!");
}).catch(MyError, function(e) {
console.log("Operation failed on " + e.item + ": " + e.message);
res.send("Error!");
});
You need to define myError to make this work (https://github.com/petkaantonov/bluebird/blob/master/API.md#catchfunction-errorclassfunction-predicate-function-handler---promise)
P.S. Sure, req.db.Employee.create(item) should support promises, so probably you will need to promisify it: https://github.com/petkaantonov/bluebird/blob/master/API.md#promisepromisifyallobject-target--object-options---object
