Mongoose, bodymen and pre validate a collection ref

[francisrod01]

Hi there! A have a question about mongoose and pre validate.

Is it possible to pre validate the request using Mongoose and bodymen and schema.tree with reference other collection as a field? . I need to validate the "user" and "location" fields.

import { Router } from 'express';
import { middleware as body } from 'bodymen';

import { token } from '../../services/passport';

import { create } from './controller';
import Company, { schema } from './model';

const router = new Router();
const {
  user,
  social_name,
...
  location,
...
} = schema.tree;

router.post('/',
  token({ required: true }),
  body({
    user,
...
   location,
...
}),
  create);

export default router;

The company model:

import mongoose, { Schema } from 'mongoose';
import mongooseKeywords from 'mongoose-keywords';

const statusList = ['a', 'd'];

const CompanySchema = new Schema({
  user: {
    type: Schema.Types.ObjectId,
    ref: 'User',
    required: true,
  },
  social_name: {
    type: String,
    trim: true,
    default: null,
  },
  fantasy_name: {
    type: String,
    trim: true,
...
  location: {
    type: Schema.Types.ObjectId,
    ref: 'Location',
    required: true,
  },
...
}

In the location field, if I POST a JSON object, it process like that:

{
  "formatted_address": "RN143, Mendoza, Argentina",
  "id": "5ba416cb667...",
  "name": "Ruta Nacional 143",
  "place_id": "C_EhlSTjE0MywgTWVuZ..."
}

And shows me an error as below:

ValidationError: location: Cast to ObjectID failed for value "[object Object]" at path "location", user: Path `user` is required.

Hey Francis.

It's not current supported that way. You can try to use other schemas though:

import { schema as userSchema } from "../user/model";
import { schema as locationSchema } from "../location/model";

body({
  user: userSchema.tree,
  location: locationSchema.tree
});

I'm not sure if that works as I've never used that approach. Let me know if it works for you. :)

I hope it will be supported soon. For the moment, I'm using body({ location: { type: Object } }).
