由于某些原因,TypeScript无法接受我的代码。在UserSchema.pre
方法中,TypeScript错误显示类型Document (this
)上不存在属性createdAt
和password
。我该如何使TypeScript接口适用于此方法并返回一个IUserDocument对象?
import {Schema, Model, Document, model} from 'mongoose';
import bcrypt from 'bcrypt-nodejs';
export interface IUserDocument extends Document{
createdAt: Date,
username: string,
displayName: string,
email: string,
googleId: string,
password: string,
verifyPassword(password:string): boolean
}
let UserSchema: Schema = new Schema({
createdAt:{
type:Date,
default:Date.now
},
username: {
type:String,
lowercase:true
},
displayName: String,
email: {
type:String,
lowercase:true
},
googleId: String,
password: String
});
UserSchema.pre('save', function(next){
var user = this;
if(!this.createdAt) this.createdAt = Date.now;
if(user.isModified('password')) {
bcrypt.genSalt(10, function(err:any, salt:number){
bcrypt.hash(user.password, salt, null, function(err:any, hash:string){
if(err) return next(err);
user.password = hash;
next();
});
});
} else{
return next();
}
});
UserSchema.methods.verifyPassword = function(password:string){
return bcrypt.compareSync(password, this.password);
}
const User = model<IUserDocument>('User', UserSchema);
export default User;
