keystoneJS relationship to self

Question

I want to create a Category model that can hold another category, but having a problem with reference field that I can set my current category to it self

Any suggestions how to achieve hierarchical categories? Does KeystoneJS have filter like 'not equal'? In other hand, maybe I can set default reference field to it self and it will be like a root...

My current code below:


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

    var PageCategory = keystone.List('PageCategory', {
        map: { name: 'name' },
        autokey : { from: 'name', path: 'key'}
    });

    PageCategory.add({
        name: { type: String, required: true, unique: true},
        image: { type: Types.CloudinaryImage, label: "Category Image"},
        description : { type: Types.Html, wysiwyg: true},
        parent: { type: Types.Relationship, ref: "PageCategory", label: "Parent category"}
    });

    PageCategory.relationship({ ref: "PageCategory", path: "parent"});

    PageCategory.register();

why does the categories example here http://keystonejs.com/docs/database/#relationships not fit your usecase? — Harry Moreno, Feb 12 '15 at 13:23

I think you have misunderstood how Model.relationship() works.

It has three options:

path, this is the "virtual" field name that will hold the values
ref, this is the model that we reference
refPath, this is the field in the referenced model that we populate path with

I think something in line with this will work for you

PageCategory.relationship({ ref: "PageCategory", path: "children", refPath: "parent"});
