在打字稿中用猫鼬填充查询 [英] Populate a query with mongoose in typescript

问题描述

我在用打字稿填充用户模型时遇到麻烦.我具有用户方案的属性，该属性是对其个人资料的引用.为了用打字稿实现猫鼬，除了架构之外，我还必须定义一个tpo/接口.我的问题是我不知道必须将什么类型分配给配置文件属性.因为如果我在不填充查询的情况下运行查询，它将是一个"ObjectId"，但是如果填充它，它将包含整个配置文件.

I'm having trouble populating my user model with typescript. I have a property of the user's scheme which is the reference to his profile. To implement mongoose with typescript I had to define a tpo / interface in addition to the schema. My problem is that I do not know what type I have to assign to the profile property. Because if I run the query without populating it, it will be an "ObjectId", but if I populate it will contain the whole profile document.

export type UserModel = mongoose.Document & {
  name: string;
  username: string; 
  email: string;
  password: string; 
  profile: Schema.Types.ObjectId; // If I leave this property with this type, in case I populate a typescript query it would give me an error. 
};


export const UserSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  username: {
    type: String,
    required: true,
    unique: true
  },
  email: {
    type: String,
    unique: true,
    required: true
  },

  password: {
    type: String,
    required: true
  },
  profile: {
    type: Schema.Types.ObjectId,
    ref: "Profile"
  }
});

export default model<UserModel>("User", UserSchema);

推荐答案

我的问题是我不知道必须将哪种类型分配给 个人资料属性.

My problem is that I do not know what type I have to assign to the profile property.

您将需要定义2种类型/接口.

You are going to need to define 2 types/interfaces.

export default model<UserModel>("User", UserSchema);

此导出操作必须使用其他界面，在该界面中您已填充个人资料"文档.

This export will have to use a different interface in which you have the populated "Profile" document.

对于架构本身，您可以将其保留为objectID类型.

For the schema itself you can leave it as an objectID type.
