Re: [xwiki-users] How to update an object only if it change

Hello, I'm prototyping a connector to a ticket tracking tool: I'm writing a Groovy page which import CSV calls into XWiki. I map each CSV rows to one XWiki object store in one page (one object per page). OK, I succeed to to it. My issue is that imported CSV contains rows (tickets) which don't change since last import and I don't want to update page in this case. Thanks to getDiff() method on BaseObject, XWiki help me to find is ticket change or not. I write the following Groovy code: def http = new HTTPBuilder( 'https://stim.gemalto.com' ) http.parser.'text/csv' = { resp -> return new CSVReader( new InputStreamReader( resp.entity.content, ParserRegistry.getCharset( resp ) ) ) } http.request( Method.GET, 'text/csv' ) { uri.path = myPath uri.query = myQuery // response handler for a success response code: response.success = { resp, csv -> if ("${resp.headers.'Content-Type'}".startsWith('text/csv')) { def names = [] def idIndex = 0 def cpt=0 // Find id column call "IncidentNumber" in my case csv.readNext().each { field -> if (field.equals('IncidentNumber')) { idIndex = cpt; } names.add(field) cpt++; } println "|=Incident Number|=action" csv.readAll().each { line -> def id = line[idIndex] def exists = xwiki.exists('myTicket.'+id) def ticketDoc = xwiki.getDocument('myTicket.'+id) def ticket = ticketDoc.newObject('myTicket.myTicketClass') for(i=0 ; i<names.size() ; i++) { ticket.set(names[i], line[i]); } print "|[[myTicket."+id+"]]|" if (!exists) { println "Added" ticketDoc.save() } else { def tickets=ticketDoc.getObjects('myTicket.myTicketClass') def oldTicket = tickets.size() != 0 ? tickets[0] : ticketDoc.newObject('myTicket.myTicketClass') def diffs=ticket.getBaseObject().getDiff(oldTicket.getBaseObject(), xwiki.context) if (diffs.size() != 0) { println "none" } else { println "Updated" ticketDoc.save() } } } } } // handler for any failure status code: response.failure = { resp -> println "Unexpected error: ${resp.status} : ${resp.statusLine.reasonPhrase}" } } The issue in my code, is that I create and add a new ticket object on each update where I want to have only one. I could removed old ticket before save but in this case history diff may not compare two tickets as there have to different GUID. I could copy new ticket fields to old ticket Or may be there is simplest way to do it implemented else where in XWiki? What do you think?
