SMW_refreshData.php breaks on RAP integration

[Fred Benenson]

Hi There,
I just upgraded to the new version of SMW and want to get RAP integration working. I got as far as installing RAP and it adds the tables to my MySQL db, but I'm getting this error:

Refreshing all semantic data in the database!
Processing pages from ID 0 to ID 1013 ...
PHP Fatal error:  Call to a member function find() on a non-object in /var/www/html/w/extensions/SemanticMediaWiki/includes/storage/SMW_RAPStore.php on line 343


When I'm trying to run SMW_refreshData.php in the maintenance directory. Any thoughts?

Thanks,

Fred

Hi, I got it fixed;

although I'm not sure of all implications, and new to semantic mediawiki and RAP, I fixed it by adding

$wgServer = "http://servername.somewhere.nl";

to mediawiki's LocalSettings.php

SMW_RAPStore guesses a modeluri to retrieve the RAP model from the database. Apparently, it does that based on the variable $wgServer in the settings. In my case $wgServer was not present, so it guessed localhost, whereas php running under apache while generating the db tables used the proper servername. You can look it up in de RAP database, table models.

After setting it, I can execute SMW_refreshData.php from the commandline again.


Cheers
Mark

Hi,

Even I got it fixed, I just ran SMW_setup.php multiple times. Then ran SMW_refreshData.php, it ran smoothly :).

cheers,
Ashwin

Ah, I see. This is in fact a general issue: SMW sometimes needs to know the
server address for making URIs or URLs, but a command-line script often
cannot get this information. Some SMW scripts already have an
option "--server=<servername>" where one can set the server for one
invocation of the script. I guess I should also add this option to
SMW_refreshData as well.
