Subtask via VTODO RELATED-TO (as Nextcloud / ownCloud / ...)

[Matthias84]

Currently subtasks are implemented as list (see #37) which is pretty nice. But as companion client which interacts with a Nextcloud server and Task app, this causes problems:

• Subtasks created via the webfrontend will become an main task at opentasks.
• Viceversa subtasks created with OT will just show up at the description field at the webfrontend.

I can deal with it, but a perfect workflow would present all infos in the same way :smile:

Technically the iCalendar / calDAV elements are referenced via RELATED-TO attributes to created a hierachy. OpenTask would need to understand this model and (maybe later) present also subtasks at the widget etc...

I really like checkboxes in the task description as currently implemented. I think the subtasks may be useful, but they are different feature.

Could you please provide few screenshots to show how other clients deal with the subtasks and how the subtasks are implemented (source code of the VTODO)?

Seems to be just as the above linked rfc says. Created those with Nextcloud:

Main task:

Yep, this is how nextcloud tasks app looks like, presenting native and your subtask implementation

FTR: opentasks-provider already supports task relations, but there is no UI support yet.

[zingmars]

@dmfs Any idea/ETA on when the UI will be implemented? If https://github.com/dmfs/opentasks/issues/321#issuecomment-287056174 (Task relations (most importantly sub-tasks, but also other relationships). I think this is already supported by the provider, just the UI part is missing. ) is to be believed then the whole thing has been stuck at this stage for quite a while.

hello @dmfs,

your work is awesome and the subtask feature as explained above would make open tasks feature complete far ahead of any other solution out there.

not only are you releasing FOSS but your clean and effective (gui) implementation is impressive.

i spent a lot of time evaluating existing solutions from evernote to todoist but the combination nextcloud/open tasks is the most flexible ON PREMISE solution existing (which even works in a cooperative manner).

please give me the possibility to motivate you continuing your great work, e.g. via a donation campaign.

[dmfs]

@webermax thanks! We're actually going to set up a small one-pager for OpenTasks and it will certainly have a donate button. At present we're focusing on getting recurrence support done. Although, we've also completed a few smaller tasks along the way (mostly minor UI/UX improvements).

Subtasks, custom alarms and categories are certainly the next big blocks once recurrence is out of the way.

[webermax]

@dmfs glad to hear that.

just checked http://dmfs.org/ and could not find any donate button yet.

looking forward seeing any news about your project anyway!

I wait for this feature too. Is there any work in progress on this or at least UI modifications ideas? From my point of view it looks as hard as replacing ListView with TreeView, isn't it?

[webermax]

@unclev I guess it is more then that. see https://github.com/dmfs/opentasks/pull/469
