Re: [xwiki-dev] create a personal rss feed

Ok here It Is : 1 - the creation of a RSS feed page: “PersonalRSS” in space “ Main” with code : $response.setContentType("text/xml") #set($baseurl = "http://${request.serverName}") #set($member = $request.uid) #set($title = "$member.replace('XWiki.','') Personal") #set($description = "Flux RSS Personal of $member.replace ('XWiki.','')") #includeForm("XWiki.PersonalRssCode") 2 – the creation of the RSS Code page: “PersonalRssCode” in space Xwiki with code : {pre} #if($member=="") #set($member="XWiki.XWikiGuest") #end #set($memberdoc = $xwiki.getDocument($member)) #set($cobj = $memberdoc.getObject("XWiki.XWikiUsers")) #set($personalrss = $memberdoc.display("blogfeed","view",$cobj)) #set($personalrss = $personalrss.replace("@","','")) #set($sql = "where doc.fullName in ('${personalrss}') order by doc.date desc") #set($list = $xwiki.searchDocuments($sql ,0, 0)) #set($rsvc= $xwiki.xWiki.getRightService()) <rdf:RDF

<dc:contributor> <rdf:Description link=""> <rdf:value>$currentdoc.author</rdf:value> </rdf:Description> </dc:contributor> </item> #end #end </rdf:RDF> {/pre} 3 – the creation of the page which add and remove chosen pages : “EditPersonalRSS” in space “Xwiki” with code : #if($request.page) #set($newrsspage = &quot;(a)${request.page}&quot;) ####### on cherche la liste #set($member = $context.getUser()) #set($memberdoc = $xwiki.getDocument($member)) #set($cobj = $memberdoc.getObject("XWiki.XWikiUsers")) ####### on recupere les pages existantes #set($oldrsspages = $memberdoc.display("blogfeed","view",$cobj)) ###################################################################### #if($request.action == "add") ####### on injecte la nouvelle #if($oldrsspages == "") #set($oldrsspages = "$newrsspage") #else #set($oldrsspages = "${newrsspage}${oldrsspages}") #end ###################################################################### #elseif($request.action == "sub") ####### on enleve la page choisie #set($oldrsspages = $oldrsspages.replace("${newrsspage}",""))) ###################################################################### #end ####### on sauve $memberdoc.use("XWiki.XWikiUsers") $memberdoc.set("blogfeed",$oldrsspages) $memberdoc.save() ####### on redirige #$response.sendRedirect($xwiki.getURL(${request.page})) #else #$response.sendRedirect($xwiki.getURL("Main.WebHome")) #end 4 – Implement the links to this Personal RSS Feed The link to create the RSS Feed: <a href="$xwiki.getURL("Main.PersonalRSS", "view", "uid=$ {context.user}&xpage=rdf")")">Personal RSS <img src="$xwiki.getSkinFile("icons/black-rss-mini.png")"></a> And in the pages you want to be followed (you can add this code in the “view.vm” page for example): #set($mdoc = $xwiki.getDocument(${context.user})) #set($cobj = $mdoc.getObject("XWiki.XWikiUsers")) #set($prss = $mdoc.display("blogfeed","view",$cobj)) #if($prss.contains(${doc.fullName})) <a href="$xwiki.getURL("XWiki.EditPersonalRSS","view","page=$ {doc.fullName}&action=sub")">Unfollow This Page</a> #else <a href="$xwiki.getURL("XWiki.EditPersonalRSS","view","page=$ {doc.fullName}&action=add")">Follow This Page with RSS</a> #end 5 – Problems encountered - I’m using the field “blogfeed”, the best is to create a new property in the Object XWiki.XWikiUsers - Everybody can follow the Personal RSS Feed of everybody just by adding the Feed with a “Xwiki.login_of_user” instead of the “${context.user}” That’s work fine, but I think it is possible to ameliorate my code.
