Automatically generates UUID for your models in a custom column

'use strict'

let merge = require('lodash.merge')
let result = require('lodash.result')

module.exports = (bookshelf, settings) => {
    // Add default settings
    settings = merge({
        type: 'v4'
    }, settings)

    // Store prototypes for later
    let modelPrototype = bookshelf.Model.prototype

    // Extends the default model class
    bookshelf.Model = bookshelf.Model.extend({
        initialize: function(attributes, options) {
            modelPrototype.initialize.call(this)

            if (this.uuid) {
                this.defaults = merge({
                    [this.uuidAttribute || 'uuid']: typeof settings.type === 'string' ? uuid[settings.type]() : settings.type.call(this, attributes, options)
                }, result(this, 'defaults'))
