Add feature: Calendar View

[xet7]

From @xet7 on January 10, 2017 17:8

Wish originally from @TutloTutlo

It's this Trello feature: http://help.trello.com/article/811-viewing-cards-in-a-calendar-view http://blog.trello.com/enable-trello-calendar-mode

There's also possibility use Trello with Google Calendar: http://help.trello.com/article/829-using-trello-with-google-calendar

This will include CalDav support. Resource: Introducing CalDav

In Sandstorm Wekan could work with some Sandstorm calendar app instead.

Copied from original issue: wefork/wekan#62

Related to #424

I think CalDAV support would provide the most flexibility.

A calendar view is urgently missing. :+1: :+1:

Exactly like the blog-article you've linked to.

[steven-tib]

+1 for the calendar view! I just discovered it on trello and would be awesome to have it in Wekan (making it even greater!!!) It would open new perspectives for the use of wekan in two current projects.

[68040]

It would open new perspectives for the use...

It's the main reason, why i can't use wekan in real life. 😞

[p-baum]

Easier than webdav would be to maintain an ics file. This could then be subscribed to from a multitude of clients (including android via icsdroid).

This would be the most useful implementation for me anyways.

[Creanimo]

+1 I urgently need a calendar view as well. I think a calendar (especially with drag and drop) could turn wekan into a very effective project management software.

I am quite new to github and I saw that sometimes people put a bounty on implementing features. Is this a possibility here?

[xet7]

There's some setup of bountysource still going on, so please wait until I have configured it correctly.

[xet7]

https://github.com/wekan/wekan/wiki/FAQ#will-my-feature-request-be-implemented

[killua-eu]

Also #1101 relevant to this issue.

[xet7]

@Creanimo

Ok it's now possible to try to add bounty to: https://www.bountysource.com/teams/wekan

Please tell me does it work Ok.

[killua-eu]

It works ok. If there's a dev to pick this up, I'll follow through and throw in a "major" $10 bountysource to verify things right to the end.

[xet7]

@killua-eu

Yes I (or somebody else in Wekan team) will implement those features that have bounties. Having a bounty raises priority a lot.

Please also add description how calendar view feature should work.

[xet7]

I did also add Commercial Support to wiki, if somebody is interested in that: https://github.com/wekan/wekan/wiki

[killua-eu]

Hey @xet7 , I took your initial description of this issue and expanded it slightly in the first list-item below, taking into account what might be a problem or what usecases come to my mind. I also added other items that are too far beyond this ticket's scope, but are connected somehow.

• trello inspired calendar view https://blog.trello.com/enable-trello-calendar-mode consisting of
  • [ ] weekly/monthly views, each with all cards stacked
  • [ ] cards draggable and filterable (changes the dates) on cal view
  • [ ] since we have both, differentiate between start and due date - not sure how about cards having both start-date and due-date defined, these would normally span multiple days in calendar apps, but that means we'll have to figure out a meaningful way to show that
  • [ ] contrary to trello, i'd consider reserving 1/n-th of the right side of the screen for tasks with no due date (so a simple todo list with items ordered according to the date they were last modified or first created)
  • [ ] caldav support (with authentication/autorization)
  • [ ] caldav url for the whole board
  • [ ] caldav url for a single user and all boards he/she participates
  • [ ] cadav url for a part of a board identified by .... (tag, user, ...)
  • [ ] notification support (send notification 1hr, 3hrs, 1day, 2days, 1week ... ahead of due date)
  • [ ] card aging
• change checklists and/or checklists items into new cards, move card to another board Whenever you deal with using a wekan-like tool to do some time-constraint scheduling, i.e. "Build sand castle (due on 20/10/2017)" and the task becomes complex over time, you can end up having almost a whole board on a single card. Right now, the only way to deal with this situation is to copy out things manually.
• odoo inspired events support #1101: Often when something has a due date and multiple people are assigned, you have some checkpoints/events along the way "Build sand castle (due on 20/10/2017)" i.e.
  • initial meeting (1/9/2017) in new york (location can be important too)
  • sand delivery (15/9/2017)
  • check if all's good and it seems we will finish on time (15/10/2017)
  • send out castle opening invites (16/10/2017) that have to be recorded somewhere/somehow and eventually should show up on the calendar. also these events should be able to send notifications and should show up in the calendar view. We could bind these event data to checklist items too if the above point gets implemented.
• bidirectional caldav support (i.e. "bind" a google calendar onto a board/lane and display events)
• having teams implemented and seeing an overview of who of the members is free/unutilized (including data anonymization - if a team member is busy on tuesday on a board i'm not participating in, i should see that he's busy but shouldnt know why)
• add card dependence (card x depends on card y)
• use dependence and calendar data to get a gantt chart
• list of tasks from all boards (can be already done via api)

Hope this paints the picture of a more complete time/scheduling implementation. If you'd like me to add more details just let me know.

[killua-eu]

And the bounty is here: https://www.bountysource.com/issues/41780513-add-feature-calendar-view , @xet7 , you're free to test the rest.

[xet7]

@killua-eu

It seems that super-productivity does not have calendar yet (see issue above) but has many other nice features.

For calendar, there are some packages for meteor: https://atmospherejs.com/packages/calendar

For example: https://atmospherejs.com/fullcalendar/fullcalendar https://fullcalendar.io

I have not checked how many of required features it has.

[killua-eu]

Firstly I'd add

• https://github.com/Serhioromano/bootstrap-calendar
• https://dhtmlx.com/docs/products/demoApps/

to the possible libraries to use. dhtmlx and fullcalendar are the two most prominently used ones imho, so that would be probably the best way to go. AFAIK fullcalendar doesnt have caldav support, but I guess none will have that. dhtmlx has a gplv2 version and i think is more polished, but i never used it in a project.

[Creanimo]

@killua-eu That is a very complete and helpful list you posted. It would be amazing if even a fraction of these features could be added!

Is there any dev here who wants to tackle this soon/next? I would rather hire someone who is already familiar with wekan.

[killua-eu]

@Creanimo, I developed an ERP that had all this and more included, so I may be having lots of ideas, some of them hopefully worthwhile for the wekan community (btw, if you like these features, you'll probably like #1160 as well).

If you'd join me in adding a bounty on this on bountysource (see above), I'll top up my bounty too - sofar I testpledged only $10. I'll also gladly provide further feature/architecture tips and experiences to anyone who may find them useful, even though I'm quite limited by not being familiar with most technologies wekan is built upon.

If you wanna go faster, please note that @xet7 also wrote up an article on commercial devrequests too on the wiki. I'd definitely be glad if wekan would move even faster as I grew quite fond of it.

[xet7]

I started implementing this yesterday 2017-08-11.

At first I'm targeting for enough functionality to be usable.

STATUS 2017-08-12

DONE

• add fullcalendar plugin to Wekan https://atmospherejs.com/rzymek/fullcalendar
• tested Calendar button on Card menu without data, and later removed it from Card menu
• added Calendar button to Wekan top right bar, in similar place like in Trello. Button currenly only opens small popup, it needs to be resized.

TODO

1) Create standalone demo outside Wekan to combine these fullcalendar demos:

LOCALES: https://fullcalendar.io/js/fullcalendar-3.4.0/demos/locales.html TIMEZONE: https://fullcalendar.io/js/fullcalendar-3.4.0/demos/timezones.html TIME RANGES: https://fullcalendar.io/js/fullcalendar-3.4.0/demos/selectable.html (possible to enlarge or shorten time range by dragging) GOOGLE CALENDAR: https://fullcalendar.io/js/fullcalendar-3.4.0/demos/gcal.html (create similar URLs inside Wekan what fullcalendar shows) EXTERNAL EVENTS: https://fullcalendar.io/js/fullcalendar-3.4.0/demos/external-dragging.html (for dragging Wekan cards to board)

2) Create gcal/caldav URLs inside Wekan to show start and due dates.

Technically:

• start and due dates are at MongoDB database
• generate gcal/caldav URLs live, similar to displaying card changes immediately in Wekan, or change to start/duedate triggering update
• add gcal/caldav authentication

3) Calendar button shows screen that shows data from gcal/caldav URLs:

• Top: Language and timezone selection - preselected according to Wekan language (or browser setting)
• Top: Change to previous or next month
• Left: Calendar display.
• Left: List of those that only have start time, no due date. On calendar those could be shown as having same start time and due date, and maybe using different color.
• Right Top: Dropdowns of lists and their cards, selected card can then be dragged to calendar using external events above.
• Right Bottom: Filtering by user.

FEEDBACK WELCOME

If anyone has improvements to this design, please add comment to this issue.

[killua-eu]

Hey @xet7 , thanks for the update, sorry for the late reply. As for now, I'd probably generate gcal/caldav URLs live, as long as this feature is in flux, triggered updates might just leave bits here and there with wrong data. As for point 3, this hits a bit the limits of my imagination, should you have a screenshot at hand, the picture surely would paint a 1000 words.

[Creanimo]

I am very excited for this!

Will the calendar be able to show the cards of selected and all boards?

[xet7]

@Creanimo

If possible, yes. I will update this issue as I get more progress.

[Creanimo]

Is there an ETA yet? O:-)

[xet7]

@Creanimo

:D I really should try to continue this. When I have had free time for Wekan, there has been so many pull requests to test and merge, bugfixes to do, releases to do, etc so I probably forgot about this, so thanks for reminding :)

[xet7]

I updated roadmap :)

[h0jeZvgoxFepBQ2C]

Yeah, please continue this :) I really need this feature :P

[Creanimo]

Do you have an ETA for us? My pledge at bounty source has a 3 month deadline on it, but I will re-pledge should the deadline pass.

[xet7]

@Creanimo

I was not aware of the deadline. Where I can see deadlines of all bounties?

[killua-eu]

I think that on bounties above 250 USD, there's a default 3 month deadline. The list of supporters and the date they pledged is here https://www.bountysource.com/issues/41780513-add-feature-calendar-view/backers

[xet7]

@Creanimo

I need to update Roadmap order, because I need to do in this order:

1) search 2) copy + move cards to other boards 3) calendar

I don't have ETA, but I try to do more Wekan and less other work.

[xet7]

Note to myself of these features wishes:

• modify the start and due dates directly in the calendar
• filter the cards with selected tags or user

[xet7]

I reorganized Roadmap and started to think that it's probably good idea to do those first that are currently in progress, before starting anything else.

[h0jeZvgoxFepBQ2C]

Is there any date where this will (maybe) available? I would really love to rollout wekan in our company, but our chief says without proper calender this is a show stopper :/ Just want to ask.. Thank you very much for this cool product!

[xet7]

@lichtamberg

I plan to have calendar feature working this year, if possible.

Also note that Let's Encrypt wildcard certificates will be available at January next year: https://letsencrypt.org/2017/07/06/wildcard-certificates-coming-jan-2018.html There is already plans to have it in Sandstorm, it makes using Sandstorm a lot easier.

For companies I recommend commercial support of Wekan Team, if you have some budget: http://www.xet7.org/wekan It really helps to speed up Wekan development, encourages contributors etc.

[Creanimo]

Just want to say how much I appreciate your hard work and that I hope that more people will use your commercial services and bountysource to support the project. Is great that wekan is still alive and developing. Side note about SSL, I am using Wekan in cloudron.io which already provides Let's Encrypt certificates for all apps. Not sure how that works technically but maybe you can benefit from some source code that is used for that.

Back to topic: I have been using Zenkit which has (among many other) a calendar view (and custom fields which are also on the roadmap). It's amazing how that takes a kanban board to a very capable project management. I think with a calendar view we can promote Wekan as a project management software, which might get you more commercial users. At least for my studio I try to use as little apps as possible and merging my brainstorming and collection tool (Wekan) with project management will streamline things a lot. Thanks again! I am excited for the future of Wekan!

[xet7]

@Creanimo

Thanks!

There is LDAP in Cloudron Wekan but it's not integrated yet.

[xet7]

@Creanimo

For Let's Encrypt certificates, current self-hosting Wekan alternatives are using in front of Wekan:

• Caddy
• Nginx with Certbot

If you want longer time between renewing SSL certs than 3 months, you can use free account at CloudFlare and there click Crypto/Origin Certificates/Create certificate that is used to encrypt traffic between your server's Nginx and CloudFlare.

[xet7]

Sorry, calendar has not progressed yet.

Here are some excuses what happened instead:

• Spending Chrismas with family etc
• Translating Sandstorm to Finnish
• Translating ReactOS Start button/menu and Taskbar to Finnish
• Trying to get Wekan upgraded Meteor 1.6 and Node 8.8.1 with no success
• Trying to get Wekan working on ARM64 yesterday on server I got from CNCF, stuck on fibers.
• Merging some pull requests, but did not make release
• Tried to fix double dash bug on snap, but because Ubuntu is importing packages from Debian, build queue is progressing very slowly, I have not checked has is built yet
• Having some urgent work for my clients
• Did blog post about 2 years of Wekan
• Added new Wekan screenshots to Wekan homepage

Well, I'll try to organize my time that I could hopefully make progress with calendar...

[xet7]

Additional requirements, sponsored by FX:

When modifying due date of a card: 1) Show info about due date change in the activities panel 2) Email card members about change of due date

[xet7]

@BaobabCoder has started implementing this as minimal implementation first.

[xet7]

Steps: 1) @BaobabCoder makes minimal implementation of Calendar feature, and this issue is closed 2) @BaobabCoder gets full bounty of this feature, just like @GhassenRjab got for minimal implementation of Search feature 3) Remaining Calendar feature requests are moved to new issue

[xet7]

@BaobabCoder has not provided any status report, so for now, I'm moving this back to my todo list.

[xet7]

@BaobabCoder came back, and is now continuing Calendar :)

[xet7]

Correction: @BaobabCoder said that he makes basic first version of calendar, adds it as pull request, and gives bounty to me, so that I can continue adding features and updates to calendar, and to support my development of Wekan, because @BaobabCoder currently has his full time job, and I only have some part-time job, doing Wekan etc. Thanks to @BaobabCoder !

[d3dbit]

IMHO, calendar view is a needed feature to improve wekan app. Thanks for continuing developing it.

Bidirectional support would be the killer feature here. CalDAV task support is basically universal and has many interfaces such as macOS Reminders, Thunderbird, etc., yet there's no Kanban type integration. @killua-eu mentioned this in the list of desired features. Are you considering bi-directional support in scope for this issue?
