Re: [Dhis2-users] [Dhis2-devs] Problem with GIS: Facility layer
Hi Hannan, can I please have a temporary username/password to your instance? Makes it a lot easier for me to detect the problem.

Please check the attached file. The coordinated of the facility layers are in the database (12185 out of 26103). The test server has the same data up to August. But the facility layer is working properly in the test servers. The organisationunit table has the same data. I attached the part of a log file. Can you please suggests how can I solve this problem.

Re: [Dhis2-users] Standard iReports cache problem
The nginx server in Rwanda is caching. Another approach might be to clear specific elements from the nginx cache, rather than to clear the entire cache, though this would require some communication between front end users and back end administrators which would probably be too cumbersome in practice. I wonder if it could be possible to automate this ... ie iterate through all reports in the cache and remove them if that report has been updated in the database. And run that every 5 minutes ...

Re: [Dhis2-users] Standard iReports cache problem
Perhaps, but for this use case five minutes may not be enough. The point is that this report should not be cached at all. How would you propose to write a script to clean out these specific resources from the cache, and leave everything else? Seems not so straightforward to me. Considering it is rather trivial to implement this in nginx by creating a different location which would not be cached, I am not convinced some script to clean up the mess is such a good idea. It would seem some script which would be triggered every X minutes would be quite un-eco-friendly, when these resources should have never been cahced to begin with? Perhaps the real fix would be to allow the report creators to specify whether the report should be cached or not cached?

Re: [Dhis2-users] Standard iReports cache problem
I think the simplest would be if we created a query param disableCache=false|true , which could be appended to the report URL manually during development phase. If true, DHIS would set a no-cache header on the response, disallowing any cache to store it. ___ Mailing list: https://launchpad.net/~dhis2-users Post to : dhis2-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~dhis2-users More help : https://help.launchpad.net/ListHelp
Re: [Dhis2-users] Standard iReports cache problem
Of course that doesn't fix the problem with the constantly updated report (unless you create a Resource and points it to that Report including that query param). If this is a special case for just one report then I guess Jason's suggestion on a special nginx location would be feasible. We could implement a system feature but that will take longer. ___ Mailing list: https://launchpad.net/~dhis2-users Post to : dhis2-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~dhis2-users More help : https://help.launchpad.net/ListHelp
