获取类型 '{ username: string; password: string; }' 的错误参数不能分配给类型 'RequiredEntityData<User>' 的参数

Question

我的项目工作良好，但我一直得到红色下划线在这行代码:

{
username: options.username,
password: hasedPassword
}

当我将它悬停时，它显示:

类型为'{username: string;密码:字符串;}不是可赋值给'RequiredEntityData'类型的参数。类型"{用户名:字符串;密码:字符串;}'缺少以下内容属性从类型'{createdAt: EntityDataItem;updatedAt:EntityDataItem;用户名:EntityDataItem;密码:EntityDataItem;}': createdAt, updatedats (2345)

这是整个文件:

import { User } from "../entities/User";
import { MyContext } from "../types";
import { Arg, Ctx, Field, InputType, Mutation, Resolver } from "type-graphql";
import argon2 from 'argon2';
@InputType()
class UsernamePasswordInput {
@Field()
username: string
@Field()
password: string
}
@Resolver()
export class UserResolver {
@Mutation(() => User) 
async register(
@Arg('options') options: UsernamePasswordInput,
@Ctx() {em}: MyContext
) {
const hasedPassword = await argon2.hash(options.password)
const user = em.create(User, {
username: options.username,
password: hasedPassword
})
await em.persistAndFlush(user)
return user
}
}

如何修复这个错误?

已更新，添加用户实体:

@ObjectType()
@Entity()
export class User {
@Field()
@PrimaryKey()
_id!: number;
@Field(() => String)
@Property()
createdAt: Date = new Date();
@Field(() => String)
@Property({ onUpdate: () => new Date() })
updatedAt: Date = new Date();
@Field(() => String)
@Property({unique: true})
username!: string;

@Property()
password!: string;
}

Answer 1

@Resolver

@Resolver()
export class UserResolver {
@Mutation(() => User) 
async register(
@Arg('options') options: UsernamePasswordInput,
@Ctx() {em}: MyContext
) {
const hasedPassword = await argon2.hash(options.password)
const user = em.create(User, {
username: options.username,
password: hasedPassword
// add these here 
createdAt: new Date,
updatedAt: new Date
})
await em.persistAndFlush(user)
return user
}
}

只是添加添加createdAt: new Date, updatedAt: new Date到{username: options.username,password: hasedPassword}

这样的{username: options.username,password: hasedPassword, createdAt: new Date, updatedAt: new Date }文本编辑器不会抛出错误。

虽然会抛出错误，但您的代码将正常工作，并且您可以向数据库添加行
