[英]Mongoose typing issue with typescript
I am building an app using mongoose and typescript. 我正在使用mongoose和typescript构建一个应用程序。 Here is a simple model I have made: 这是我制作的简单模型:
import * as callbackMongoose from 'mongoose';
var mongoose = callbackMongoose;
mongoose.Promise = global.Promise;
const Schema = mongoose.Schema;
var userSchema = new Schema({
username: String,
email: String,
hash: String
});
export default mongoose.model('User', userSchema);
It works well but I need to cast each document to any before accessing properties. 它运行良好但我需要在访问属性之前将每个文档转换为任何文档。 I read a guide that said I could do this: 我读了一个说我可以这样做的指南:
interface IUser extends mongoose.Document {
username: String;
email: String;
hash: String;
}
export default mongoose.model<IUser>('User', userSchema);
My problem is that the type mongoose doesn't seem to have the property Document
. 我的问题是类型mongoose似乎没有属性Document
。 It also doesn't have the property ObjectId
. 它也没有ObjectId
属性。 When I cast mongoose to any and use these members it works just fine. 当我把猫鼬投到任何人并使用这些成员时它工作得很好。 It seems to be a typing issue. 这似乎是打字问题。
I installed the mongoose typing like so: 我像这样安装了猫鼬类型:
npm install @types/mongoose --save
The typings do work for Schema and they are good for all of the other libraries I use. 这些类型适用于Schema,它们适用于我使用的所有其他库。 Is something wrong with these type definitions? 这些类型定义有问题吗? Am I doing something wrong? 难道我做错了什么?
For TypeScript@2.0 I think you may use 对于TypeScript@2.0,我想你可以使用
npm install @types/mongoose --save
instead of: 代替:
npm install @typings/mongoose --save
This is full example: 这是完整的例子:
Database.ts Database.ts
import mongoose = require('mongoose');
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://admin:123456@ds149437.mlab.com:49437/samples');
export { mongoose };
UserData.ts UserData.ts
import { mongoose } from './../../Services/Database';
export interface UserData {
is_temporary: boolean;
is_verified: boolean;
status: boolean;
username: string;
}
export interface IUserData extends UserData, mongoose.Document, mongoose.PassportLocalDocument { };
UserModel.ts UserModel.ts
import { IUserData } from './UserData';
import { mongoose } from './../../Services/Database';
import * as passportLocalMongoose from 'passport-local-mongoose';
import Schema = mongoose.Schema;
const UserSchema = new Schema({
username: { type: String, required: true },
password: String,
status: { type: Boolean, required: true },
is_verified: { type: Boolean, required: true },
is_temporary: { type: Boolean, required: true }
});
UserSchema.plugin(passportLocalMongoose);
var UserModel;
try {
// Throws an error if 'Name' hasn't been registered
UserModel = mongoose.model('User')
} catch (e) {
UserModel = mongoose.model<IUserData>('User', UserSchema);
}
export = UserModel;
I also full project example using typescript, node.js, mongoose & passport.js right here: https://github.com/thanhtruong0315/typescript-express-passportjs 我也在这里使用typescript,node.js,mongoose和passport.js的完整项目示例: https : //github.com/thanhtruong0315/typescript-express-passportjs
Good luck. 祝好运。
