LoopBack is an open source Node.js framework built on top of Express optimized for mobile, web, and other devices. Connect to multiple data sources, write business logic in Node.js, glue on top of your existing services and data, connect using JS, iOS & Android SDKs.
Hi, I have created a model and trying to cast/validate the post req body. But, loopback is ignoring the model definition.
Model Definition :
import {Entity, model, property} from '@loopback/repository';
import {company, customer} from '../interfaces';
@model()
export class BulkCompany extends Entity {
@property({
type: 'number',
id: true,
generated: true,
})
id?: number;
@property({
type: 'object',
required: true,
})
company: company;
@property({
type: 'object',
required: true,
})
customer: customer;
constructor(data?: Partial<BulkCompany>) {
super(data);
}
}
export interface BulkCompanyRelations {
// describe navigational properties here
}
export type BulkCompanyWithRelations = BulkCompany & BulkCompanyRelations;
Interfaces :
export interface beneficialOwners {
name: string;
title: string;
ownershipPercentage: number;
}
export interface company {
name: string;
state: string;
type: string;
designator: string;
website: string;
description: string;
industry: string;
beneficialOwners: beneficialOwners[];
alternateName: string;
}
export interface customer {
email: string;
name: string;
phone: string;
addressLine1: string;
addressCity: string;
addressState: string;
addressZip: string;
}
Route :
async createBulkCompanies(
@requestBody({
content: {
'application/json': {
schema: {
type: 'array',
additionalProperties: false,
items: getModelSchemaRef(BulkCompany, {
title: 'BulkCompany',
exclude: ['id'],
}),
},
},
},
})
company: [Omit<BulkCompany, 'id'>],
): Promise<any> {}
Problem is i am not getting a validation on company.beneficialOwners

Hi @mightytyphoon, Slack is the recommended platform.

Question: by following the todo-list tutorial, in the relational db section, we get the following decorator on the Todo model:
@model({
settings: {
foreignKeys: {
fk_todo_todoListId: {
name: 'fk_todo_todoListId',
entity: 'TodoList',
entityKey: 'id',
foreignKey: 'todoListId',
},
},
},
})
export class Todo extends Entity { /* ... */ }But when running npm run migrate I got an error stating that the foreign key property does not exists.
In fact, I checked the queries issued by the migration, I noticed that theTodo.todoListId property is mapped to Todo.todolistid column (notice the lowercase!). By changing the foreignKey: 'todoListId' to foreignKey: 'todolistid' it works.
The problem is that the tutorial doesn't change the generated column name. Did I miss anything? Or is this an issue with the tutorial?
Hi Guys, I have a problem with loopback v3 and loopback-connector-mongodb. I have the following method with an Aggregation.
Company.extendedFind = async function(region, search) {
const companyCollection = Company.getDataSource().connector.collection(Company.app.models.Company.modelName);
const $and = [
{ 'account.type': 'recruiter' },
{ _isDeleted: { $exists: false }},
];
if (region) {
$and.push({ 'account.region': region });
}
if (search) {
$and.push({ $or: [{ name: { $regex: search, $options: 'i' }}, { 'account.email': { $regex: search, $options: 'i' }}] });
}
return await companyCollection.aggregate([
{ $lookup: { from: 'Account', localField: 'accountId', foreignField: '_id', as: 'account' }},
{ $unwind: '$account' },
{ $match: { $and: $and }},
{ $lookup: { from: 'JobAd', let: { id: '$_id' }, pipeline: [{ $match: { $expr: { $and: [{ $eq: ['$$id', '$companyId'] }, { $eq: ['$status', 'Published'] }] }}}], as: 'jobAds' }},
{ $sort: { name: 1 }},
{ $project: { id: 1, name: 1, createdAt: 1, credits: 1, accountId: 1, 'account.email': 1, 'account.region': 1, numOfJobs: { $size: '$jobAds' }}},
// { $project: { id: 1, name: 1, createdAt: 1, credits: 1, accountId: 1, 'account.email': 1, 'account.region': 1 }},
], { allowDiskUse: true }).toArray();
};I have about 1000 company and account records, as well as about 10k JobAd records. On the mongoshell the query takes 1.8 seconds. For whatever reason running this through loopback as api call it takes more then 20 seconds.
The issue is the lookup for the JobAd model, when I remove it then is also very fast through loopback.
Any idea what the issue could be?
We have a legacy loopback3 codebase, just wondering whether loopback-connector-postgresql latest version support loopback3. From the readme it seems so, but I'm not sure
