Member Function Documentation

static SDRServiceCache::updateAverageReviewRating

(

$

cserdId

)

[static]

Update the average review rating for an item in SDR.

Connect to the CSERD database and average the responses for the "usability" question among published reviews. Then take this value, connect to the SDR database, and update the resource record and cache for the given cserdId using that average value.

XXXTodo: Group by user so that one user can't have extra sway on the rating

Parameters:

$cserdId

[int]: The cserdId to update

Returns:

[bool]: True on success, false on error

SDRServiceCache::updateResourceCacheHelper

(

$

mixed

)

Update the cache for this resource in the SDRResourceCache table.

Use information from this resource object and its SDRMetadataObj object to insert a cache of values and metadata XML. If there is no live version, remove any existing cache for this resource from the table.

SDRServiceCache::updateResourceVersionCaches	(	$	resource,
		$	version
	)

SDRServiceCache::updateSearchWordCache

(

$

version

)

Update the quick search word count cache for this resource, using this version.

Insert the (relevant) words found in all metadata values in this version into SDRSearchWord and insert rows into SDRSearchWordCount matching the following: the search words, the number of times they occur, this resource, and the fields to which the words apply. The two caching tables can be used by SDR's quick find engine to do a quick relevance search on a set of keywords.
