Hello,

How can I map project fields to custom fields? My backend API returns fields in snake_case format, but the library by default expects camelCase. I tried extending the ProjectModel class as follows, but it doesn't seem to be working:

import { ProjectModel } from "@bryntum/gantt";

export default class MyProjectModel extends ProjectModel {
  static get fields() {
    return [
      {
        name: "startDate",
        dataSource: "start_date",
      },
    ];
  }
}

Thanks in advance!

Additionally, can I do the same for load/sync payloads?

Hi,

That should be working as you showed, but I tested it and found it's not working. I've opened a ticket https://github.com/bryntum/support/issues/9796
You can subscribe on ticket updates to be notified when it's done.

load/sync should simply pick up correct field mapping after setting it in ProjectModel.

Sorry for inconveniences!

Thanks, Alex! This is a blocker for us. Could you please provide us with an ETA?

Hey wzantout,

As it was recently created, we'll need some debugging from our dev team to be able to provide an ETA, please watch the ticket to check when a milestone is set to it, and then you'll have an estimation of when the fix will be available.

Hi could you please share version on Bryntum lib you used? I just re-tested it in lastest release and it worked there.
You can check in our advanced demo with small changes applied

in launch-sass.json

{
  "success" : true,
  "project" : {
    "calendar"     : "general",
    "start_date"    : "2019-01-18", <<<<<<<

In app.js

import ProjectModel from '../../lib/Gantt/model/ProjectModel.js';

class MyProjectModel extends ProjectModel {
    static idField = 'Id';

static get fields() {
    return [
        { name : 'name', dataSource : 'Name' },
        { name : 'startDate', dataSource : 'start_date' }
    ];
}
}

const pm = new MyProjectModel({
    // Let the Project know we want to use our own Task model with custom fields / methods
    taskModelClass : Task,
    transport      : {
        load : {
            url : '../_datasets/launch-saas.json'
        }
    },
    autoLoad  : true,
    taskStore : {
        wbsMode : 'auto'
    },
    // The State TrackingManager which the UndoRedo widget in the toolbar uses
    stm : {
        autoRecord : true
    },
    // Reset Undo / Redo after each load
    resetUndoRedoQueuesAfterLoad : true
});

const gantt = new Gantt({
    appendTo : 'container',
    

project : pm,
