Я пытаюсь создать приложение с помощью Nestjs, и в настоящее время у меня есть два модуля: User и Auth со следующей структурой:
![enter image description here](https://i.stack.imgur.com/N8Zyz.png)
Мне нужновнедрить UsersService в AuthService для взаимодействия с User сущностью, поэтому сначала я внедрил UsersRepositoy в UsersService и экспортировал службу:
users.module.ts:
import { Module } from '@nestjs/common';
import { UsersService } from './users.service';
import { TypeOrmModule } from '@nestjs/typeorm';
import { UserRepository } from './user.repository';
@Module({
imports: [
TypeOrmModule.forFeature([UserRepository]),
],
providers: [
UsersService,
UserRepository,
],
exports: [
UsersService,
TypeOrmModule,
],
})
export class UsersModule {}
users.service.ts:
import { Injectable } from '@nestjs/common';
import { AuthCredentialsDto } from '../auth/dto/auth-credentials.dto';
import { JwtPayload } from '../auth/jwt-payload.interface';
import { User } from './user.entity';
import { InjectRepository } from '@nestjs/typeorm';
import { UserRepository } from './user.repository';
@Injectable()
export class UsersService {
constructor(
@InjectRepository(UserRepository)
private userRepository: UserRepository,
) {}
async signUp(authCredentialsDto: AuthCredentialsDto): Promise<void> {
return this.userRepository.signUp(authCredentialsDto);
}
async validateUserPassword(authCredentialsDto: AuthCredentialsDto): Promise<string> {
return this.userRepository.validateUserPassword(authCredentialsDto);
}
async findOne({ username }: JwtPayload): Promise<User> {
return this.userRepository.findOne({ username });
}
}
users.repository.ts:
import { ConflictException, Injectable, InternalServerErrorException } from '@nestjs/common';
import * as bcrypt from 'bcrypt';
import { Repository, EntityRepository } from 'typeorm';
import { User } from './user.entity';
import { AuthCredentialsDto } from '../auth/dto/auth-credentials.dto';
@Injectable()
@EntityRepository(User)
export class UserRepository extends Repository<User> {
async signUp(authCredentialsDto: AuthCredentialsDto): Promise<void> {
const { username, password } = authCredentialsDto;
const salt = await bcrypt.genSalt();
const user = new User();
user.username = username;
user.password = await this.hashPassword(password, salt);
user.salt = salt;
try {
await user.save();
} catch (error) {
if (error.code === '23505') {
throw new ConflictException('Username already exists');
} else {
throw new InternalServerErrorException();
}
}
}
async validateUserPassword(authCredentialsDto: AuthCredentialsDto): Promise<string> {
const { username, password } = authCredentialsDto;
const user = await this.manager.findOne(User, { username });
if (user && await user.validatePassword(password)) {
return user.username;
} else {
return null;
}
}
private async hashPassword(password: string, salt: string): Promise<string> {
return bcrypt.hash(password, salt);
}
}
Проблема в том, когда мне нужно вызвать UserService методов из AuthService , я получу ошибку в следующем формате:
[Nest] 6267 - 11/08/2019, 3:30:52 AM [ExceptionsHandler] Cannot read property 'findOne' of undefined +4600ms

Мой вопрос ... что я пропускаю, вызывая эту болезненную проблему! Спасибо заранее.
