Issue
I try to create method hashPassword for user schema.
schema.method("hashPassword", function (): void {
const salt = bcrypt.genSaltSync(10);
const hash = bcrypt.hashSync(this.password, salt);
this.password = hash;
});
And get an error Property 'password' does not exist on type 'Document<any>'.
on password
Here is my file
import mongoose, { Schema, Document } from "mongoose";
import bcrypt from "bcryptjs";
/**
* This interface should be the same as JWTPayload declared in types/global.d.ts file
*/
export interface IUser extends Document {
name: string;
email: string;
username: string;
password: string;
confirmed: boolean;
hashPassword: () => void;
checkPassword: (password: string) => boolean;
}
// User schema
const schema = new Schema(
{
name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
},
username: {
type: String,
required: true,
},
password: {
type: String,
required: true,
},
confirmed: {
type: Boolean,
default: false,
},
},
{ timestamps: true }
);
schema.method("hashPassword", function (): void {
const salt = bcrypt.genSaltSync(10);
const hash = bcrypt.hashSync(this.password, salt);
this.password = hash;
});
// User model
export const User = mongoose.model<IUser>("User", schema, "users");
Solution
At the point where you define the method, the schema
object doesn't know that it is the Schema
for an IUser
and not just any Document
. You need to set the generic type for the Schema
when you create it: new Schema<IUser>( ... )
.
