Re: [xwiki-devs] [VOTE] Retire old query plugin

Hi, The reality right now is that there is no alternative to this code that has been moved to legacy, at least for part of it. Let me explain a bit what some of this code is doing. - it allows to create a java object XWikiQuery which represents an XWiki Query in Java as a structured object per field. This object stores criterias - the XWiki Core itself provides a function to display a search field for each field of an XWiki class (displaySearch) and a function that allows to retrieve the content of search a search field into an XWikiQuery object, as well as a function to transform the part concerning the field in the XWikiQuery object into an XWQL statement portion - some functions in XWiki.java (moved to aspects in legacy) also allow to generate a field to choose the columns and the sort fields for a query - the query plugin allows to transform the XWikiQuery object into an XWQL statement including the sort fields - a function in XWiki.java allows in one call to read the data from $request, create the XWikiQuery object, transform it in XWQL, run the query and display the results as an HTML table - another function allows just to run the query and velocity code can present the results just the way you decide The end results is a system to build query interfaces dynamically. We haven't used this code because nobody has been trained on it. But still it's very powerful code, and I'd hate to see it go away without a replacement. Currently it's not that complex to keep it. Most of the code is in the XWiki fields anyway. The code in XWikiQuery and in QueryPlugin is not that complicated as it's just looping over the fields. On the long run this code has even more capabilities, like being able to run query aggregates in addition to just listing XWiki documents. This could allow to do counting and summing using a UI and even generate a graph out of the result using the Graph Plugin. Once you activate the QueryPlugin in xwiki.cfg this code still works. It would be great if somebody from the active committers looked at it and we could work together to see where this code should be headed. I'm available to help understand the code. Right now the key functions are: - the XWikiQuery class - QueryPlugin.makeQuery - XWiki.createQueryFromRequest - XWiki.displaySearch - XWiki.displaySearchColumns - XWiki.displaySearchOrder - and code in each XWiki Field class less important code is: - XWiki.search(XWikiQuery) - XWiki.searchAsTable(XWikiQuery) Ludovic 2012/11/16 Thomas Mortagne <thomas.mortagne(a)xwiki.com> -- Ludovic Dubost Founder and CEO Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost
