Typeorm 打字稿存储库 findone - 类型参数不可分配给“FindOneOptions<GuildConfiguration>”类型的参数

Question

这是我的配置文件。

import { Column, Entity, PrimaryGeneratedColumn } from 'typeorm';

@Entity({ name: 'guild_configurations' })
export class GuildConfiguration {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ unique: true, name: 'guild_id' })
  guildId: string;

  @Column({ default: '?' })
  prefix: string;

  @Column({ name: 'welcome_channel_id', nullable: true })
  welcomeChannelId: string;
}

我试图添加搜索 guildId 与不和谐的 guild.id

// https://discord.js.org/#/docs/main/stable/class/Client?scrollTo=e-guildCreate
import { Guild } from 'discord.js';
import BaseEvent from '../utils/structures/BaseEvent';
import DiscordClient from '../client/client';
import { getRepository, ObjectID } from 'typeorm';
import { GuildConfiguration } from '../typeorm/entities/GuildConfiguration';

export default class GuildCreateEvent extends BaseEvent {
  constructor(
    private readonly guildConfigRepository = getRepository(GuildConfiguration)
  ) {
    super('guildCreate');
  }
  
  async run(client: DiscordClient, guild: Guild) {
    console.log("Hello World");
    console.log(`Joined ${guild.name}`);
    const config = await this.guildConfigRepository.findOne({guildId:guild.id});
    if(config){
      console.log("A configuration was found!")
    }else{
      console.log("Configuration was not found. Creating one...")
      const newConfig = this.guildConfigRepository.create({guildId:guild.id})
      return this.guildConfigRepository.save(newConfig);
    }
    
  }
}

this.guildConfigRepository.findOne({guildId:guild.id}); 表明

类型为 '{ guildId: string; 的参数 }' 不可分配给“FindOneOptions”类型的参数。对象文字只能指定已知属性，并且“FindOneOptions”类型中不存在“guildId”。ts(2345)

我的 typeorm 版本是 "typeorm": "^0.3.1" 有谁知道如何解决这个问题？谢谢！

Answer 1

您可以使用该where密钥，例如：

this.guildConfigRepository.findOne({ 
  where: { 
    guildId: guild.id 
  } 
});

Answer 2

当您使用 0.3.x typeorm 时，您可以使用findOneBy代替findOne.

const config = await this.guildConfigRepository.findOneBy({guildId:guild.id});
