TypeError: RecordsRemover is not a constructor (forest-admin-mongoose)

Expected behavior

Should remove multiple records: https://docs.forestadmin.com/documentation/v/v6/reference-guide/routes/default-routes#delete-a-list-of-records

Actual behavior

From the code stated in the above documentation link, I get TypeError: RecordsRemover is not a constructor

const express = require('express');
const { PermissionMiddlewareCreator, 
  RecordsGetter } = require('forest-express-mongoose');
const { outfitProductsCollection } = require('../models');
const mongoose = require('mongoose');

const router = express.Router();
const permissionMiddlewareCreator = new PermissionMiddlewareCreator('outfitProductsCollection');

/* The others routes*/

// Delete a list of outfits
router.delete('/outfitProductsCollection', permissionMiddlewareCreator.delete(), (request, response, next) => {
  // Learn what this route does here: https://docs.forestadmin.com/documentation/v/v6/reference-guide/routes/default-routes#delete-a-list-of-records
  new RecordsGetter(outfitProductsCollection).getIdsFromRequest(request)
  .then((ids) => {
    const recordsRemover = new RecordsRemover(ids);
      .then(() => response.status(204).send())

I am using the latest version of ForestAdmin (setup from the website using Docker)

Hi :wave: @Thomas welcome to our community.
How did you import the RecordsRemover?

const { RecordsRemover } = require('forest-express-sequelize');


Updated the question, sorry for the missing imports :slight_smile:

Note: forest-express-sequelize is for SQL, but we’re currently on MongoDB so we use forest-express-mongoose

Ok so, the import looks good.
Which version of forest-express-mongoose do you use?

Question updated with the package json :slight_smile:

It’s seem to have a missed export on our end :scream:.
We will work on a fix soon.
But you can do this to achieve the wanted behavior.

const { ResourcesRemover } = require('forest-express-mongoose');

const recordsRemover = new ResourcesRemover(outfitProductsCollection, ids);
  .then(() => response.status(204).send())

Hope it’s help


Alright, that what I thought. Thanks for your feedback, can you update me once you release the export of RecordsRemover please?

Thanks! :slight_smile:

Hi @Thomas,

We just released a new version of forest-express-mongoose (and forest-express-sequelize) that exposes the RecordsRemover service. You will have to update your dependency to latest version (i.e: 6.2.1):

# Using yarn
yarn add forest-express-mongoose@latest
# Or with NPM
npm i forest-express-mongoose@latest

Then you can update your delete route. I just tried on one of my local projects with this code and it works (using a users model):

// Delete a list of Users
router.delete('/users', permissionMiddlewareCreator.delete(), (request, response, next) => {
  new RecordsGetter(users).getIdsFromRequest(request)
    .then((ids) => {
      const recordsRemover = new RecordsRemover(users);
        .then(() => response.status(204).send())

Side note: currently, there are a some errors in the documentation about this method, it will be fixed soon! Lines 17 to 20 should be updated since we have to use remove instead of perform:

const recordsRemover = new RecordsRemover(companies);
  .then(() => response.status(204).send())

Edit: Documentation is now up-to-date.

Let us know if it fixes your problem!
