Select using a external collection

If possible how could you populate a select (options property) with an external Mongo collection?

Here’s what I’ve tried so far:

import { Mongo } from 'meteor/mongo'
import Schema from 'simpl-schema'

import {api as PeopleApi} from './People' // a mongo collection

const peopleData = PeopleApi.find({}).fetch().map(obj => obj['name'])

export const api = new Mongo.Collection('Service')

export const schema = new Schema({
  name: {
    type: String,
    optional: false,
    label: 'Name'
  },
  person: {
    type: String,
    allowedValues: [...peopleData]
  },
  active: {
    type: Boolean,
    label: 'Active',
    defaultValue: true
  }
})

export default api

@caiobep allowedValues (and most of the props) can be a function, which is then executed each time the allowedValues array is needed. (You can also call .map directly after find() without the fetch.)

export const schema = new Schema({
  person: {
    type: String,
    allowedValues() {
      return PeopleApi.find().map(obj => obj.name);
    }
  },
  // ...
})

Obviously you’ll need to make sure the PeopleApi subscription is ready before you validate if this is in client code.

Ah, in which case it may be because .find().fetch() returns a promise and isn’t resolved when you create the schema.
