import { Document, model, Schema, SchemaDefinition } from 'mongoose'

import { authSchema, IAuthSchema } from './userAuth'

// the model

export interface IUser {
  _id: ObjectID, // !WARNING: No default value in Schema
  auth: IAuthSchema
}

// IUser will act like it is a Schema, it is more common to use this
// For example you can use this type at passport.serialize
export type IUserSchema = IUser & SchemaDefinition
// IUser will act like it is a Document
export type IUserDocument = IUser & Document

export const userSchema = new Schema({
  auth: {
    required: true,
    type: authSchema,
  }
})

export default model('user', userSchema)
