类型&#39；任务&#39；不满足约束&#39；文档&#39； [英] Type 'Task' does not satisfy the constraint 'Document'

问题描述

我正在使用Nestjs和MongoDB创建API。tasks.service.ts，尝试创建getall终结点，但得到TypeScript错误： Type 'Task' does not satisfy the constraint 'Document'. Type 'Task' is missing the following properties from type 'Document': increment, model, $isDeleted, remove, and 51 more.

tasks.service.ts

import { Injectable, HttpStatus } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { Task } from './dto/task.inferface';

@Injectable()
export class TasksService {
  private readonly Tasks: Task[] = [];

  constructor(@InjectModel('Task') private readonly TaskModel: Model<Task>) {}

  async getAll(): Promise<Task> {
    const tasks = await this.TaskModel.find().exec();
    return tasks;
  }
}

推荐答案

从接口扩展Document类。

import { Document } from 'mongoose';

export interface Task extends Document {
 //Task info ...
}
