Help:Automatic query update
| Table of Contents | |
|---|---|
Currently Semantic MediaWiki (as of 1.9.2 and by the time of writing this help) does not support a "real" auto update (aka "smart" queries*) that would refresh the results of pages that include the query results but to mitigate this shortcoming the following scenarios are supported:
"smart" queries where an algorithm is used to find a data diff which would trigger a refresh of only those related subjects and its queries within the store (and hopefully invalidates the MediaWiki html/parser cache as well otherwise it prevents the page from displaying the updated results).
Manual refresh/store update[edit]
From Semantic MediaWiki 1.9.0 using "action=purge" ("refresh" tab not <F5> key) in combination with $smwgAutoRefreshOnPurge allows to refresh (update the store) of a single page manually.
Selected automatic refresh[edit]
If a manual refresh of a page is not an option, you could use the --query parameter in "rebuildData.php" maintenance script (introduced with Semantic MediaWiki 1.9.2) to select a group of pages (using a query condition) that are refreshed on a repeated schedule (through a job etc.).
FAQ[edit]
- What about
$smwgQConceptCacheLifetime?
As the name suggests the setting is only relevant to the "lifetime" of concept caches and has no effect on queries or caches that are not related to concepts.
- Browser and F5 key
<F5> is only relevant to the browser cache which does not include the html/parser cache of a wikipage.
If you want to refresh a wikipage then you should use the provided "refresh" button (action=purge) to initiate a html/parser cache refresh.
