Cast to ObjectId failed for value "order" (type string) at path "_id" for model "Product"

I'm trying to make API orders. The problem appears when I want to display all orders from the database using the GET method, but I get a 500 error and a message
CastError: Cast to ObjectId failed for value "order" (type string) at path "_id" for model "Product"
order.schemas.ts
#Schema()
export class Order {
#Prop()
username: string;
#Prop()
phone: string;
#Prop()
email: string;
#Prop()
adr: string;
#Prop({type: [{type: mongoose.Schema.Types.ObjectId, ref: 'Product'}]})
products_id: Product[];
}
product.schema.ts
#Schema()
export class Product {
#Prop()
name: string;
#Prop()
catalog_number: string;
#Prop()
old_price: number;
#Prop()
price: number;
#Prop()
desc_text: string;
#Prop()
desc_short: string;
#Prop()
image: string;
#Prop({type: [{type: mongoose.Schema.Types.ObjectId, ref: 'Order'}]})
orders: Order[];
}
This is file order.controller
#Controller('/order')
export class OrderController {
constructor(private orderServise: OrderService) { }
#Post()
create_order(#Body() dto: CreateOrderDto) {
return this.orderServise.create_order(dto);
}
#Get()
get_All() {
return this.orderServise.get_All();
}
#Get(':id')
getOne(#Param('id') id: ObjectId) {
return this.orderServise.getOne(id);
}
#Delete(':id')
delete(#Param('id') id: ObjectId) {
return this.orderServise.delete(id);
}
}
This is file order.service
#Injectable()
export class OrderService {
constructor(#InjectModel(Product.name) private productModule: Model<ProductDocument>,
#InjectModel(Order.name) private orderModule: Model<OrderDocument>) {}
async create_order (dto: CreateOrderDto): Promise<Order> {
const order = await this.orderModule.create({...dto });
return order;
}
async get_All(): Promise<Order[]> {
const order = await this.orderModule.find()
return order;
}
async getOne(id: ObjectId): Promise<Order>{
const order = await this.orderModule.findById(id).populate('products_id');
return order;
}
async delete(id: ObjectId): Promise<Order>{
const order = await this.orderModule.findOneAndDelete(id);
return order._id;
}
}

Creating named parameter to base class in typescript and javascript

I have created a base model class with is a model for the incoming data, I will be modeling the data inside of a class for some external reasons. Although I ran into a problem with is defining the incoming data into this model class.
This is my class
export class EntityBasic {
constructor(
public id: string,
public title: string,
public urn?: string,
public risk_level?: string,
public be_aware?: string,
public body?: string,
public published_at?: string,
public created_at?: string,
public updated_at?: string,
public description?: string,
public notes?: string,
) {}}
}
How I define the content inside of it in another page:
public getEntity(setEntity) {
return new EntityBasic(
setEntity.id,
setEntity.title,
setEntity?.urn,
setEntity?.risk_level,
setEntity?.be_aware,
setEntity?.body,
setEntity?.published_at,
setEntity?.created_at,
setEntity?.updated_at,
setEntity?.report?.summary || '',
setEntity?.report?.metadata?.source_notes,
setEntity?.report?.metadata?.notes,
);
}
But defining the data like so, gave me problems, since some times there won't be a urn, or a risk_level for example, and the data will be messed up inside the class.
I would like a way to define like so (This didnt work):
public getEntity(setEntity) {
return new EntityBasic(
id = setEntity.id,
title = setEntity.title,
urn = setEntity?.urn,
risk_level = setEntity?.risk_level,
)
}

I believe wrap all parameters into one object is the best solution.
Wrap them as interface
interface EntityBasicParameters {
id: string;
title: string;
urn?: string;
risk_level?: string;
be_aware?: string;
body?: string;
published_at?: string;
created_at?: string;
updated_at?: string;
description?: string;
notes?: string;
}
Accept only this object as constructor parameter
export class EntityBasic {
constructor(params: EntityBasicParameters) {}}
}
Now you can pass existent data only
public getEntity(setEntity) {
return new EntityBasic({
id: setEntity.id,
title: setEntity.title,
urn: setEntity?.urn,
risk_level: setEntity?.risk_level,
})
}
or just
public getEntity(setEntity) {
return new EntityBasic(setEntity)
}

How I can use getter and setter in TypeORM

How I can use getter and setter in TypeORM.
I saw issues in here and also here, but not found answer
For example a left my User entity
export class User {
#PrimaryGeneratedColumn()
private id: number;
#Column()
#Length(4, 20)
#IsNotEmpty()
private name: string;
#Column()
#Length(4, 100)
#IsNotEmpty()
private password: string;
public getId(): number {
return this.id;
}
public getPassword(password: string): string {
return this.password;
}
public setPassword(password: string): User {
this.password = bcrypt.hashSync(password, 8);
return this;
}
public setName(name: string): User {
this.name = name;
return this;
}
}
I use TypeORM version 0.2.7

#BeforeInsert & #AfterLoad
BeforeInsert https://typeorm.io/#/listeners-and-subscribers/beforeinsert
AfterLoad https://typeorm.io/#/listeners-and-subscribers/afterload
Use #BeforeInsert as setter
#Entity()
export class Post {
#BeforeInsert()
updateDates() {
this.createdDate = new Date()
}
}
Use #AfterLoad as getter
#Entity()
export class Post {
#AfterInsert()
resetCounters() {
this.counters = 0
}
}

Create instance of object in typescript Angular 2

How to create new instance in TypeScript. Obviously I'm not matching the constructor but I can't see what's wrong.
export class User implements IUser {
public id: number;
public username: string;
public firstname: string;
public lastname: string;
public birthday: string;
public email: string;
public constructor(iUser: IUser)
{
this.id = iUser.id;
this.username = iUser.username;
this.firstname = iUser.firstname;
this.lastname = iUser.lastname;
this.birthday = iUser.birthday;
this.email = iUser.email;
}
}
interface IUser {
id?: number;
username: string;
firstname: string;
lastname: string;
birthday: string;
email: string;
}
And student class that extends user
export class Student extends User implements IStudent, IUser {
public indeks: string;
public studyProgram: StudyProgram;
public constructor(iUser: IUser, iStudent: IStudent)
{
super(iUser);
this.indeks = iStudent.indeks;
this.studyProgram = iStudent.studyProgram;
}
}
interface IStudent {
indeks: string;
studyProgram: StudyProgram;
}
So, when I try to create new instance of student I got this error
Supplied parameters do not match any signature of call target.
this.student = new Student ({
username: '',
firstname: '',
lastname: '',
birthday: '',
email: '',
indeks: '',
studyProgram: new StudyProgram({
name: '',
duration: 0,
courseType: ''
})
});
And here is StudyProgram class
export class StudyProgram implements StudyProgramInterface {
public id: number;
public name: string;
public duration: number;
public courseType: string;
public studentList: Array<Student>;
public constructor(studyProgramCfg: StudyProgramInterface) {
this.id = studyProgramCfg.id;
this.name = studyProgramCfg.name;
this.duration = studyProgramCfg.duration;
this.courseType = studyProgramCfg.courseType;
}
}
interface StudyProgramInterface {
id?: number;
name: string;
duration: number;
courseType: string;
}

The Student class constructor is expecting two objects (one implementing IStudent, and the other implementing IUser), you are passing only one. I think the constructor you are looking for is:
public constructor(student: IUser & IStudent) {
super(student);
this.indeks = student.indeks;
this.studyProgram = student.studyProgram;
}

Angular 5 show data from firebase nodes

i need a bit of help.
I am trying to display data from specific loged in user but i have a hard time.
in html :
<div *ngFor="let to of UnData">
TS:
export class something {
todo: AngularFireList<any>;
UnData = [];
userId: string;
constructor(public navCtrl: NavController, public navParams: NavParams, private db: AngularFireDatabase, private fire: AngularFireAuth) {
this.fire.authState.subscribe(user =>{
if(user) this.userId = user.uid
});
if (!this.userId) return;
this.db.list("people/${this.userId}").valueChanges().subscribe(_data => {
this.UnData = _data;
console.log(this.UnData);
});
}
console.log gives me nothing in return. I think i am doing something wrong in code where i am getting data from database. Please give me a bit of help :-)

Thanks Frank,
the first problem was backticks but i still had problems and solved and important part was ngOnInit(userId:string):
export class something {
todo: AngularFireList<any>;
unData = [];
userId: string;
title: string;
desc: string;
constructor(public navCtrl: NavController, public navParams: NavParams, private db: AngularFireDatabase, private fire: AngularFireAuth) {
this.fire.authState.subscribe(user => {
if (user) {
this.userId = user.uid;
console.log(this.userId);
}
});
}
postDatatoDB(title: string, desc: string, userId: string): void {
this.db.list("/tasks/" + this.userId).push({ title: title, desc: desc });
this.title = '';
this.desc = '';
}
**ngOnInit(userId:string)** {
this.db.list<any>(`/tasks/${this.userId}`).valueChanges().subscribe(data => {
this.unData = data;
console.log(this.unData);
});
}
}
