import { PermissionModel } from '../permissions';

@Table({
  tableName: 'roles',

export class RoleModel extends Model {
  @BelongsToMany(() => PermissionModel, () => RolePermissionModel)
  permissions?: Array<PermissionModel & { RolePermissionModel: RolePermissionModel }>;
}

import { BelongsToMany, Model, Table } from 'sequelize-typescript';

import { RoleModel, RolePermissionModel } from '../roles';

@Table({
  tableName: 'permissions',

export class PermissionModel extends Model {
  @BelongsToMany(() => RoleModel, () => RolePermissionModel)
  roles?: Array<RoleModel & { RolePermissionModel: RolePermissionModel }>;

import { BelongsTo, Column, ForeignKey, Model, Table } from 'sequelize-typescript';

import { RoleModel } from './role.model';

@Table({
  tableName: 'roles-permissions',

export class RolePermissionModel extends Model {
  @Column
  @ForeignKey(() => RoleModel)
  roleId!: number;

  @BelongsTo(() => RoleModel, 'roleId')
  role!: RoleModel;

  @Column
  @ForeignKey(() => PermissionModel)
  permissionId!: number;

  @BelongsTo(() => PermissionModel, 'permissionId')
  permission!: PermissionModel;
