User stats json

[nbumbarger]

This adds a worker that can be run to generate per user statistics. The worker generates a simple JSON file that can be put on S3 to be served as a static JSON API endpoint.

• Example: http://osm-taskingmanager-stats.s3.amazonaws.com/users.json

This builds on work related to Missing Maps with Red Cross to get Tasking Manager data per user, instead of only per task: AmericanRedCross/tasking-manager-stats#1.
​
This is a short term solution to exposing an external API for user stats. In the longer term, if it makes sense to have a more robust user data API, a refactor of the database would enable better integration of per user stats. We've put this script in a worker-stats to organize it outside of the main OSMTM code. This could be run as a scheduled task every 10 mins to generate a new file.

@dodobas @pgiraud Couple items of note for:

• This only has the default user/pass for osmtm database
• Not really managing environment variables in a configurable way

Ideally this script should be integrated into OSMTM2 scheduling.

In the mean time, script is executed every minute and the output is available at http://tasks.hotosm.org/user-stats.json

@dodobas did this ever get deployed?

[dodobas]

not in this form, but there is an extra script on the server that generates user-data.... https://github.com/AmericanRedCross/tasking-manager-stats

we might consider integrating it with osmtm2...

Is there any update on this feature? It is very sad view on the badges saying zero finished tasks in TM.

@Jakuje Actually, this was supposed to be fixed this week, but the person who does it has been out sick all week :(
Hopefully they get better this weekend and we can get it going again next week.
