How to specify multiple fields in Keystone.js List Map?

Question

Want to know how to specify multiple fields in Keystone.js List Map.

For example, based on the Keystone Data Model documentation:

var keystone = require('keystone'),
    Types = keystone.Field.Types;

var Post = new keystone.List('Post', {
    autokey: { path: 'slug', from: 'title', unique: true },
    map: { name: 'title' },
    defaultSort: '-createdAt'
});

Post.add({
    title: { type: String, required: true },
    state: { type: Types.Select, options: 'draft, published, archived', default: 'draft' },
    author: { type: Types.Relationship, ref: 'User' },
    createdAt: { type: Date, default: Date.now },
    publishedAt: Date,
    image: { type: Types.CloudinaryImage },
    content: {
        brief: { type: Types.Html, wysiwyg: true, height: 150 },
        extended: { type: Types.Html, wysiwyg: true, height: 400 }
    }
});

Post.defaultColumns = 'title, state|20%, author, publishedAt|15%'
Post.register();

Can I make use of both title and author to create a map, such that both 2 fields will be used in foreign Model Relationship?

var Post = new keystone.List('Post', {
    autokey: { path: 'slug', from: 'title', unique: true },
    map: { name: 'author, title' },
    defaultSort: '-createdAt'
});

I got an "undefined" in Admin UI.

Did you ever find a solution to this? I'm facing the same issue, and documentation is scarce. — PullJosh, Mar 29 '18 at 23:14
@PullJosh I'm curious, why do you need to create a map based on two fields? — Megidd, Apr 03 '18 at 13:19
Creating a map with two fields is very useful. For example an Invoice No. is based on Client plus Date; or Client plus Supplier, etc. — Thomas Choy, Apr 09 '18 at 08:03

I can achieve the multiple key map by Genereated Value:

The example model Post can be written as below:

var keystone = require('keystone'),
    Types = keystone.Field.Types;

var Post = new keystone.List('Post', {
    autokey: { path: 'slug', from: 'newKey', unique: true },
    map: { name: 'newKey' },
    defaultSort: '-createdAt'
});

Post.add({
    newKey: { type: Types.Text, watch: true, noedit: true, value: function (callback) {
        var author = this.author;
        var title = this.title;
        keystone.list('User').model.findOne({_id: this.author.toString()}).exec(function (err, u) {
            if (err) {
                callback(err, "unknown")
            } else {
                var r = "("+u.name.first+" "+u.name.last+")-"+title;
                callback(null, r)
            }
        });
    }},
    title: { type: String, required: true, index: true, initial: true },
    state: { type: Types.Select, options: 'draft, published, archived', default: 'draft' },
    author: { type: Types.Relationship, ref: 'User', index: true, initial: true },
    createdAt: { type: Date, default: Date.now },
    publishedAt: Date,
    image: { type: Types.CloudinaryImage },
    content: {
        brief: { type: Types.Html, wysiwyg: true, height: 150 },
        extended: { type: Types.Html, wysiwyg: true, height: 400 }
    }
});

Post.defaultColumns = 'title, state|20%, author, publishedAt|15%'
Post.register();

For the above model, when creating Post, it will initially ask for Title and Author:

This will create a Post like this, with mutliple fields as a map:
