How to access enumValues in mongoose from a Model or Document

enum-access.js

var mongoose = require('./index')
  , TempSchema = new mongoose.Schema({
      salutation: {type: String, enum: ['Mr.', 'Mrs.', 'Ms.']}
    }); 

var Temp = mongoose.model('Temp', TempSchema);

console.log(Temp.schema.path('salutation').enumValues);
var temp = new Temp();
console.log(temp.schema.path('salutation').enumValues);

thanks!

thanks!!! :)

great!

Thanks

So neat, but doesn't work for me (mongoose 3.6.20): for the path() function, my enum fields must be prefixed with ".enum", and there is no "enumValues" property on the returned object. This works for me... console.log(Temp.schema.path('salutation.enum').options.type) // We get ['Mr.', 'Mrs.', 'Ms.']

Update: bnoguchi's neater version works if you do Temp.path("salutation").enum('Mr.', 'Mrs.', 'Ms.'); after you've defined the schema (i was using salutation: {enum: ['Mr.', 'Mrs.', 'Ms.']} in the Schema constructor parameter, which doesn't seem to work as well).

I've salutation sub-document inside profile document, so Temp.schema.path('profile.salutation').enumValues works in my case.

Thanks!

Great!!

This was very helpful. Thanks

Thanks a lot, helpful!!

Thank you

If you want to know all the enum values inside in array type, you need something like this:

temp.path('salutation.0.type').enumValues

👍 This kind of thing is possible too :

collaboration.schema.path('typeRef').enumValues[0]

Wow, I was just wondering how to do this as I need the enum data to implement a droplist. Very helpful, thanks!

Thanks

Perfect, thank you!

Thank you!

How to access the enum from a non-model schema? Like if I am using a discriminator schema and in that schema, there is enum field, how can I can access that?

nice!

nice

thanks.

To find enums of all enum properties:

const schema = Temp.schema;
const enums = Object.keys(schema.obj)
        .filter(k => schema.obj[k].hasOwnProperty('enum'))
        .map(k => {
          let o = {};
          o[k] = schema.obj[k].enum;
          return o;
        })
        .reduce((r, v) => Object.assign(r, v), {});

Just what I needed. Thank you!

for me it worked like this:

//model typeContacts.js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const arrayTypeContacts = [
{ type: 'phone', name: 'principal', icon: 'phone' },
{ type: 'email', name: 'principal', icon: 'envelope' },
{ type: 'whatsapp', name: 'principal', icon: 'whatsapp' },
];
const TypeConctactSchema = Schema({
contactType: {
type: String,
enum: arrayTypeContacts,
default: arrayTypeContacts
}
});

const TypeContacts = mongoose.model('typecontacts', TypeConctactSchema);
module.exports = TypeContacts;

//controller
const data = await TypeContactModel.schema.path('contactType').options.enum;

thank you a lot!!
