how to change return req.user object name of passport-local? - nestjs

Question

I'm developing a backend using nestjs and passport-local strategy. I use local strategy only for owners login in my projects. but at end of validation it returns the owner in req.user.
how can I change it so it returns the owner in req.owner?
import { Injectable } from '#nestjs/common';
import { OwnerService } from '../owner/owner.service';
#Injectable()
export class AuthService {
constructor(private ownerService: OwnerService) {}
async validateOwner(username: string, pass: string): Promise<any> {
const owner = await this.ownerService.findOneByUsername(username);
// later check with hashed pass
if (owner && owner.owner && owner.owner.password === pass) {
const { password, ...result } = owner.owner;
return result;
}
return null;
}
}
and
import { Strategy } from 'passport-local';
import { PassportStrategy } from '#nestjs/passport';
import { Injectable, HttpException } from '#nestjs/common';
import { AuthService } from './auth.service';
#Injectable()
export class LocalStrategy extends PassportStrategy(Strategy) {
constructor(private authService: AuthService) {
super({
usernameField: 'username',
passwordField: 'password',
});
}
async validate(username: string, password: string): Promise<any> {
const owner = await this.authService.validateOwner(username, password);
if (!owner) {
throw new HttpException('No Owner found', 404);
}
return owner;
}
}
how I use it:
#UseGuards(AuthGuard('local'))
#Post('login')
async login(#Request() req) {
console.log(req.owner, req.user);
return req.owner;
}
req.owner is empty but req.user has value
UPDATE:
my Authmodule.ts:
import { Module } from '#nestjs/common';
import { AuthService } from './auth.service';
import { OwnerModule } from '../owner/owner.module';
import { LocalStrategy } from './local.strategy';
import { PassportModule } from '#nestjs/passport';
import { JwtModule } from '#nestjs/jwt';
#Module({
providers: [AuthService, LocalStrategy],
imports: [
OwnerModule,
PassportModule.register({
property: 'owner',
})
],
exports: [AuthService],
})
export class AuthModule {}

Answer 1

PassportModule.register({ property: 'owner' })
where PassportModule is imported from #nestjs/passport

Answer 2

I created a LocalAuthGuard class that extends my local strategy:
import { Injectable } from '#nestjs/common';
import { AuthGuard } from '#nestjs/passport';
#Injectable()
export class LocalAuthGuard extends AuthGuard('local') {
constructor() {
super({
property: 'owner',
});
}
}
then wherever I use this guard, it adds my target field to req.owner instead of req.user.
#UseGuards(LocalAuthGuard)
#Post('login')
async login(#Request() req): Promise<LoginResponse> {
return this.authService.login(req.owner);
}
