我正在使用mongoose和typescript构建应用程序。这是我制作的一个简单模型:
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);
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。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);
我的问题是类型mongoose似乎没有属性Document
。它也没有属性ObjectId
。当我把猫鼬投到任何人并使用这些成员时它工作得很好。这似乎是打字问题。
我安装了像这样的猫鼬类型:
npm install @types/mongoose --save
这些类型适用于Schema,它们适用于我使用的所有其他库。这些类型定义有问题吗?我做错了吗?
答案 0 :(得分:3)
对于TypeScript@2.0 我想你可以用
npm install @types/mongoose --save
而不是:
npm install @typings/mongoose --save
这是完整的例子:
<强> Database.ts 强>
import mongoose = require('mongoose');
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://admin:123456@ds149437.mlab.com:49437/samples');
export { mongoose };
<强> UserData.ts 强>
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 { };
<强> UserModel.ts 强>
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;
我也使用typescript,node.js,mongoose&amp; amp; passport.js就在这里:https://github.com/thanhtruong0315/typescript-express-passportjs
祝你好运。
