[INFO REQ] Daily basis for gantt

[remyvillulles]

Hi,

Is it possible to ignore hours (use only days) for gantt? My tasks end up having a 1.9 duration but we'd like them to be per day.

Thank you,
Remy

How do you mean ignore? Render 1.9 as 1, or 2? Something else?

[remyvillulles]

Sorry, set the time basis to days instead of hours. When I resize mes tasks, I can resize them per hour, I'd like to resize them per day.

Seems like you need the same functionality like here: viewtopic.php?f=52&t=16055
Set up viewPreset https://bryntum.com/docs/gantt/#Gantt/view/Gantt#config-viewPreset
with your config for https://bryntum.com/docs/gantt/#Scheduler/preset/ViewPreset#field-timeResolution

All the best,
Alex

Please read docs here: https://bryntum.com/docs/gantt/#Gantt/view/Gantt#config-viewPreset
If you don't provide a full config of your viewPreset, you need to specify base property in your config, as example:

viewPreset : {
  base           : 'hourAndDay',
  id             : 'myHourAndDayPreset',
  timeResolution : {
      unit      : "day",
      increment : 1
  },
  [...]

By doing like this:

viewPreset: new ViewPreset({
    id: "ganttPreset",
    base: "day",
    timeResolution: {
      unit: "day",
      increment: 1,
    },
  }),

I have the following error (which by the way completely crashes the app like a lot of unhandled errors within bryntum, I have to close the tab and reopen it...)

What version of the Gantt are you currently using? I tested it with our basic example in 4.0.3 using umd build and it works to me with your config.

new Gantt({
    appendTo : 'container',

project,

viewPreset : {
    base    : 'day',
    id      : 'ganttPreset',
    timeResolution : {
        unit      : 'day',
        increment : 1
      }
},

[...]
});

Try to reproduce with our examples, please?
Btw, I see not enough closed braces in the end of your snippet. Cannot be sure, of course.

All best,
Alex

The issue seemed to be the new ViewPreset which wasn't working. Using the object directly seems okay. However, if I drag a task and on the overlay, it gets to the next day. If I release the mouse click at this point, it shows me 5.9 days instead of the 6 expected (see screenshots)

On this screenshot, I'm dragging the task from the 20th to the 21st of september and Bryntum is showing me 21st

Here I released the mouse button at the same place it is on the first image but the duration is incorrect

Please pay attention to the start date. It's few hours shifted ahead (on both screenshoots). Since the start date in not at the midnight, the duration is less than 6 days.
