NestJS/Mongoose:序列化不排除普通输出中的属性
我开始玩nestjs,从我以前的express/mongoose项目迁移过来,紧接着nestjs文档中的mongodb/serializations章节,我立即撞上了围栏。我已经准备好了下面的模式NestJS/Mongoose:序列化不排除普通输出中的属性,nestjs,nestjs-mongoose,Nestjs,Nestjs Mongoose,我开始玩nestjs,从我以前的express/mongoose项目迁移过来,紧接着nestjs文档中的mongodb/serializations章节,我立即撞上了围栏。我已经准备好了下面的模式 /////// schema import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose'; import * as mongoose from 'mongoose'; import { Exclude, Expose } from 'c

已在app.module中注册

并尝试了以下调用,希望结果中没有显示密码属性

最后,我发现只有用户类的手动实例化才能完成它应该做的事情,所以我向用户类添加了构造函数
constructor(partial?: Partial<User>) {
if (partial)
Object.assign(this, partial);
}
构造函数(部分?:部分){
如果(部分)
对象。分配(此,部分);
}
然后它最终返回了预期的结果-结果中没有密码道具
@UseInterceptors(ClassSerializerInterceptor)
@Get('first')
async first(): Promise<User> {
return new User(await this.userModel.findOne().lean());
}
//finally returns what's expected
// {"name":"Kos","login":"kos","__v":0,"id":"5f8731a36fc003421db08921"}
@UseInterceptors(ClassSerializerInterceptor)
@获取('第一')
async first():承诺{
返回新用户(等待this.userModel.findOne().lean());
}
//最终返回预期结果
//{“name”:“Kos”,“login”:“Kos”,“__v”:0,“id”:“5f8731a36fc003421db08921”}
我错过什么了吗?不知何故,这似乎有点让人难以承受
更新:这是关于nestjs mongoose和序列化耦合的问题-为什么
@UseInterceptors(ClassSerializerInterceptor)
@Get('first')
async first(): Promise<User> {
return await this.userModel.findOne().lean();
}
@UseInterceptors(ClassSerializerInterceptor)
@获取('第一')
async first():承诺{
return wait this.userModel.findOne().lean();
}
不起作用,这个
@UseInterceptors(ClassSerializerInterceptor)
@Get('first')
async first(): Promise<User> {
return new User(await this.userModel.findOne().lean());
}
@UseInterceptors(ClassSerializerInterceptor)
@获取('第一')
async first():承诺{
返回新用户(等待this.userModel.findOne().lean());
}
有效(这也意味着对于每个需要实体创建的结果可枚举映射)我想我已经找到了解决方案
@Schema()
导出类用户{
@属性({select:false})
密码:字符串;
@支柱(
用户名:字符串;
}
当您对装饰器执行此操作时,mongo内部属性的值在查找中被忽略。我有一个问题要问您,您是否希望在每次选择或创建时都隐藏?这是关于nestjs mongoose和序列化耦合的问题-为什么这
@UseInterceptors(ClassSerializerInterceptor)。。。return wait this.userModel.findOne().lean()
不起作用,此@UseInterceptors(ClassSerializerInterceptor)。。。返回新用户(等待此.userModel.findOne().lean())
worksNo,我只想从UI部分隐藏此字段的值,这样我就可以执行console.log(User.password)或任何等式检查,但将用户实体返回到前端,而不需要有价值的道具
