Authorization

We have 2 ways authorization

1. Use decorator CheckPermission and AuthzGuard

  @Post()
  @UseGuards(AuthzGuard)
  @CheckPermission([PermissionsType.CREATE, FeaturesType.ORDER])
  async create(@Body() createOrderDto: CreateOrderDto, @CurrentUser() user) {
    return this.ordersService.createOrder(createOrderDto);
  }

2. Use caslAbilityFactory

  @Post()
  @UseGuards(AuthzGuard)
  async create(@Body() createOrderDto: CreateOrderDto, @CurrentUser() user) {
    const ability = await this.caslAbilityFactory.createForUser(user.sub);
    if (ability.can(PermissionsType.CREATE, FeaturesType.ORDER)) {
      return this.ordersService.createOrder(createOrderDto);
    }
    throw new CustomForbiddenException();
  }
