Allow users to see their time statistics

[MichaelBuessemeyer]

This PR enables the time statistics for non-admin users. If the user is not an admin, the view just displays the logged in user's time statistics.
Currently, the view can only be opened at <base-url>/reports/timetracking if you are not an admin.
There needs to be a link added to this view e.g. in the navbar.

URL of deployed dev instance (used for testing):

• https://allowuserstoseetimestats.webknossos.xyz

Steps to test:

• Log in as a non-admin user.
• Open <base-url>/reports/timetracking.
• The view should instantly display your statistics as the logged in user is chosen as a default user.

Issues:

• fixes Allow users to see their own time statistics #3905

---

• Updated changelog
• [ ] Updated migration guide if applicable
• [ ] Updated documentation if applicable
• [ ] Adapted wk-connect if datastore API changes
• [ ] Needs datastore update after deployment
• Ready for review

@fm3 @youri-k Can you please do the backend work for this?
As far as I know, the request for time statistics needs to be adjusted so that the every logged in user can see his statistics 🙂

TODO-frontend

• make the statistics view accessible via UI/Link
• fix the flow bug

@fm3 I just pushed a version which seems to be working. Would you be so kind and double check especially that we're not introducing data leaks. Thx

Backend LGTM + tested :)

@philippotto Could you please review the frontend changes :)?

Nice, the code itself looks good! However, the lab told us to do other improvements on the time statistics before releasing it to the hiwis (see #4076). So, this PR is blocked by that, too. I'd suggest to do the broader improvements in this PR, as well. Let's talk about at the sprint meeting tomorrow.

Frontend TODOs

• display task id instead of annotation id.
• remove duplicated data as this results in a second line mentioned as the second point in the discuss post.
• show date instead of time and when time is show use 24 hour instead of am/pm.
  hint:

 hAxis: {
   format: "hh/M/d/yy",
}

• Do not repeat dates on the x axis - Can't find a fix
• Refine the tooltip

• remove "duplicated" data as this results in a second line mentioned as the second point in the discuss post.

When the timestamps of an ending of a task and the beginning of another take are very close, the second element might be wrapped into another row.
I cannot find any posts/fixes about this matter online.

• Do not repeat dates on the x axis - Can't find a fix

There were posts but none of the suggested fixed worked :/

@philippotto Could you please review the changes for the first time 🙂 ?

Nice! The code looks good 👍 Let's wait for the lab feedback now.

Interesting... Out of curiosity, how did you find that workaround? Was it posted somewhere? If so, you could add the link so that we can follow-up with this later (maybe this will be fixed in another version of the plotting lib).

[MichaelBuessemeyer]

The actual hint was here https://developers.google.com/chart/interactive/docs/gallery/timeline#customizing-tooltips:

Hovering over a bar brings up a tooltip with the text defined in the third column. In this chart, we have to set the second column to dummy values (here, null) so that our tooltips can exist in the third column.

Imo This does not make any sense, but it finally worked after reading this 🙂.

[philippotto]

Thank you! Can you add the link as a comment to the code? :)

[philippotto]

@MichaelBuessemeyer Could you please remove the "time tracking link" for ordinary users (so that they won't be able to see the view) and then get this PR ready to merge? The lab wants the UX improvements first and in the second round, we can make it available to all users.

Backend LGTM

Nice!
