I encountered a persistent error within my teachers.service:
Object literal may only specify known properties, and 'id' does not exist in type 'FindOptionsWhere | FindOptionsWhere[]'.ts(2353) FindOneOptions.d.ts(23, 5): The expected type comes from property 'where' which is declared here on type 'FindOneOptions' (property) id: number No quick fixes available
import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository, UpdateResult, DeleteResult } from 'typeorm';
import { Teacher } from '../entities/teacher.entity';
@Injectable()
export class TeachersService {
constructor(
@InjectRepository(Teacher)
private teachersRepository: Repository<Teacher>,
) {}
findAll(): Promise<Teacher[]> {
return this.teachersRepository.find();
}
async findOne(id: number): Promise<Teacher | null> {
return this.teachersRepository.findOne({
where: {
id,
},
});
}
create(teacher: Teacher): Promise<Teacher> {
return this.teachersRepository.save(teacher);
}
async update(id: number, teacher: Teacher): Promise<Teacher> {
await this.teachersRepository.update(id, teacher);
return this.findOne(id);
}
async remove(id: number): Promise<void> {
await this.teachersRepository.delete(id);
}
}
Here is the structure of my Teacher entity:
import { Entity, Column, PrimaryGeneratedColumn, OneToMany } from 'typeorm';
import { Class } from './class.entity';
@Entity()
export class Teacher {
@PrimaryGeneratedColumn()
teacher_id: number;
@Column()
teacher_name: string;
@Column()
teacher_lastname: string;
@Column()
teacher_email: string;
@OneToMany(() => Class, (classEntity) => classEntity.teacher)
classes: Class[];
}
