How To Specify Multiple Fields In Keystone.js List Map?

Want to know how to specify multiple fields in Keystone.js List Map. For example, based on the Keystone Data Model documentation: http://keystonejs.com/docs/database/ var keystone

Solution 1:

I can achieve the multiple key map by Genereated Value:

The example model Post can be written as below:

varkeystone=require('keystone'),Types=keystone.Field.Types;varPost=newkeystone.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) {
        varauthor=this.author;vartitle=this.title;keystone.list('User').model.findOne({_id:this.author.toString()}).exec(function(err, u) {
            if(err) {
                callback(err, "unknown")
            } else {
                varr="("+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:
