[Dhis2-devs] Remove a full level from the pyramid

2017-09-18 Thread Martin Van Aken

Hello,
We have a DHIS2 instance we support that already has data (Health Pyramid,
Data Elements, DataValues). The system takes into account a level that is
actually not used by most people and more importantly not by systems we
need to integrate with.

On a business side, it make sense removing it altogether - I'm wondering if
someone already did something like that and how ?

I can imagine something such as (supposing last level is 4 and we remove
level 3):

- Check any data linked to Org Unit of level 3 and backup/delete
- Reattach all org unit of level 4 to their grand parent (level 2)
- Delete level 3 entities
- Regenerate or update the level 4 to 3

I suppose this would be easier done in the DB than with the API.

Anyone with experience or advice on a process like that ?

Thanks,

Martin

2017-09-18 Thread Jason Pickering

Hi Martin,

I  do not think we  have anything specifically for that, but I think you
could write a short script

1) Reassign the direct descendants of the level you want to remove to the
desired level.  This could be done through the API or SQL I guess.
2) Use this script

to
remove the level. You would need to loop through all of the levels to
remove of course.
3) Clear the cache and rebuild the orgunit paths.

Regards,
Jason

Thanks. What I don't know is how the OrgUnitLevel would react - we'll need
to update those too. I think they are linked through a simple number (and
not a foreign key to the level table), but I may be wrong.

The script you shared is about deleting all data linked to a specific org
unit, right ? Not sure how it related to levels.

Re: [Dhis2-devs] Remove a full level from the pyramid

2017-09-18 Thread Jason Pickering

Don't worry about the level. This should be regenerated when you regenerate
the path, but you better check. Otherwise, it should be pretty simple to
assign this  with SQL.

Where the delete_orgunit_with_data function comes in may be more apparent
from the following example which should move all children of Badjia
chiefdom up a level and then deletes Badjia (from the Sierra Leone DB).  I
did not include the loop here.


Loop over all leaf nodes and move them up a level.

UPDATE organisationunit
SET parentid = (SELECT organisationunitid from organisationunit
WHERE path = '/ImspTQPwCqd/O6uvpzGd5pu')
WHERE path ~('/ImspTQPwCqd/O6uvpzGd5pu/YuQRtpLP10I')
AND hierarchylevel = 4;

. Delete the Badjia which no longer has any children.

sierra-leone=# SELECT * FROM delete_orgunit_with_data('YuQRtpLP10I');
 delete_orgunit_with_data
--
1
(1 row)


That SQL would need to be tweaked a bit I think, but maybe its a bit
clearer?

Jason

Re: [Dhis2-devs] Remove a full level from the pyramid

2017-09-18 Thread Martin Van Aken

Thanks a lot, that clarify it. When you say the level should be
regenerated, is this some kind of SQL trigger or it is a check/update the
app does itself on start ? I was thinking to update those manually too
(does not looks like a lot).

Your script is actually handy to already check any link between the org
unit to be deleted and the rest of the application - I suppose your list of
delete should be all links there, so I can use it as a check.

Re: [Dhis2-devs] Remove a full level from the pyramid

2017-09-18 Thread Jason Pickering

I mean that the level and path should be regenerated by DHIS2, and does not
need to be generated by the SQL script. The path and level should be
properties which are "figured out" by DHIS2 based on the position of the
orgunit in the hierarchy.
