adminjs-typeorm

This is an official AdminJS adapter which integrates TypeORM into AdminJS. (originally forked from Arteha/admin-bro-typeorm)

Installation: yarn add @adminjs/typeorm

Usage

The plugin can be registered using standard AdminJS.registerAdapter method.

import { Database, Resource } from '@adminjs/typeorm'
import AdminJS from 'adminjs'

AdminJS.registerAdapter({ Database, Resource });

// Optional: if you use class-validator you have to inject this to resource.
import { validate } from 'class-validator'
Resource.validate = validate

Example

import {
  BaseEntity,
  Entity, PrimaryGeneratedColumn, Column,
  ManyToOne,
  RelationId
} from 'typeorm'
import { MyDataSource } from './my-data-source'
import * as express from 'express'
import { Database, Resource } from '@adminjs/typeorm'
import { validate } from 'class-validator'

import AdminJS from 'adminjs'
import * as AdminJSExpress from '@adminjs/express'

Resource.validate = validate
AdminJS.registerAdapter({ Database, Resource })

@Entity()
export class Person extends BaseEntity
{
  @PrimaryGeneratedColumn()
  public id: number;

  @Column({type: 'varchar'})
  public firstName: string;

  @Column({type: 'varchar'})
  public lastName: string;

  @ManyToOne(type => CarDealer, carDealer => carDealer.cars)
  organization: Organization;

  // in order be able to fetch resources in adminjs - we have to have id available
  @RelationId((person: Person) => person.organization)
  organizationId: number;

  // For fancy clickable relation links:
  public toString(): string
  {
    return `${firstName} ${lastName}`;
  }
}

( async () =>
{
  await MyDataSource.initialize();

  const adminJs = new AdminJS({
    // databases: [MyDataSource],
    resources: [
      { resource: Person, options: { parent: { name: 'foobar' } } }
      ],
    rootPath: '/admin',
  })

  const app = express()
  const router = AdminJSExpress.buildRouter(adminJs)
  app.use(adminJs.options.rootPath, router)
  app.listen(3000)
})()

ManyToOne

Admin supports ManyToOne relationship but you also have to define @RealationId as stated in the example above.
