我创建了一个Mongoose Schema并为Model添加了一些名为Campaign的静态方法.

如果我是console.log Campaign我可以看到它上面的方法.问题是我不知道在哪里添加这些方法,以便Typescript也知道它们.

如果我将它们添加到我的CampaignModelInterface,它们仅适用于模型的实例(或者至少TS认为它们是).

campaignSchema.ts

  export interface CampaignModelInterface extends CampaignInterface, Document {
      // will only show on model instance
  }

  export const CampaignSchema = new Schema({
      title: { type: String, required: true },
      titleId: { type: String, required: true }
      ...etc
  )}

  CampaignSchema.statics.getLiveCampaigns = Promise.method(function (){
      const now: Date = new Date()
      return this.find({
           $and: [{startDate: {$lte: now} }, {endDate: {$gte: now} }]
      }).exec()
  })

  const Campaign = mongoose.model<CampaignModelInterface>('Campaign', CampaignSchema)
  export default Campaign

我也试过通过Campaign.schema.statics访问它,但没有运气.

任何人都可以建议如何让TS了解模型中存在的方法,而不是模型实例？

我正在使用本文中概述的typescript实现mongoose模型的过程:https://github.com/Appsilon/styleguide/wiki/mongoose-typescript-models并且我不确定在使用数组时这是如何转换的子文档.假设我有以下模型和模式定义:

interface IPet {  
    name: {type: mongoose.Types.String, required: true},   
    type: {type: mongoose.Types.String, required: true}   
}

export = IPet


interface IUser {   
    email: string;    
    password: string;   
    displayName: string;   
    pets: mongoose.Types.DocumentArray<IPetModel>   
};

export = IUser;


import mongoose = require("mongoose");  
import IUser = require("../../shared/Users/IUser");   
interface IUserModel extends IUser, mongoose.Document { }

import mongoose = require("mongoose");   
import IPet = require("../../shared/Pets/IPet");   
interface IPetModel extends IPet, Subdocument { }

将新宠物添加到user.pet子文档的代码:

addNewPet = (userId: string, newPet: IPet){
    var _user = mongoose.model<IUserModel>("User", userSchema);
    let …
