Live Table component

Failed to execute the [velocity] macro. Cause: [The execution of the [velocity] script macro is not allowed in [xwiki:Documentation.DevGuide.FrontendResources.LiveTable.WebHome]. Check the rights of its last author or the parameters if it's rendered from another script.]. Click on this message for details.

#includeMacros("TutorialsCode.LiveTableResultsMacros")

#gridresultwithfilter("" $request.collist.split(",") "" "doc.space='Tutorials' and doc.name<>'WebHome' and doc.name<>'WebPreferences'")

The page at TutorialsCode.LiveTableResultsMacros should contain a copy of the default code for the live table result page. The next step implies extracting the rating information from the wiki pages located the Tutorials space. We add a new velocity macro which will test the presence of the rating object with class XWiki.AverageRatingsClass and extract the rating value.
##
## list ratings
##
#macro(grid_ratings $udoc)
  #set($ratings = "")
  #set($ratingObj = "")
  #set($ratingObj = $udoc.getObject("XWiki.AverageRatingsClass"))
  #if("$!ratingObj" != "")
     #set($ratings = $ratingObj.get("averagevote"))
  #end
#end
The continue our extension of this component, we need to add a test for the presence of our custom column to call the <tt>grid_ratings</tt> macro when generating the JSON:
...
#elseif($colname=="_images") ,
  #grid_photolist($udoc)
  "${colname}" : "${photolist}"
#elseif($colname=="_ratings"),
  #grid_ratings($udoc)
  "${colname}" : "${ratings}"
#else ,
...

#info("Firebug can be a useful tool when testing the JSON code generated.")
