[xwiki-devs] Setting XWiki groups and users up programmatically

2 Feb 2009

      Hi,

i'm trying to do a conceptually very, very simple task and find myself  
obscured to death by
xwiki's data model (shall we call it one for now ...)

After hitting my head on the lack of API for user, I somehow (dont ask  
me how) manage to
assemble some code for creating a user. This CAN NOT be right?!

	            Map map = Util.getObject(context.getRequest(), "register");
	            String content = "#includeForm(\"XWiki.XWikiUserSheet\")";
	            String template =  
context.getRequest().getParameter("template");
	            String parent =  
context.getRequest().getParameter("parent");

	            if ("superadmin".equalsIgnoreCase(wikiname)) {
	            	log.error("Can't register user 'superadmin'. Name  
reserved.");
	                return;
	            }

	            try {
	                if (! 
context.getUtil().match(context.getWiki().Param("xwiki.validusername",  
"/^[a-zA-Z0-9_]+$/"), wikiname)) {
	                    log.warn("Illegal username '"+wikiname+"'");
	                }
	            } catch (RuntimeException ex) {
	                log.error("Invalid regular expression for  
xwiki.validusername", ex);
	                if (!context.getUtil().match("/^[a-zA-Z0-9_]+$/",  
wikiname)) {
	                	log.error("Illegal username '"+wikiname+"'");
	                }
	            }

	            if ((template != null) && (!template.equals(""))) {
	                XWikiDocument tdoc =  
context.getWiki().getDocument(template, context);
	                if ((!tdoc.isNew())) {
	                    content = tdoc.getContent();
	                }
	            }

	            if ((parent == null) || (parent.equals(""))) {
	                parent = "XWiki.XWikiUsers";
	            }

	            // add password
	            map.put("password", wikiname);
	            map.put("active", "1");

	            if (log.isDebugEnabled()) {
	            	log.debug("Creating user with parameters:  
"+map.toString());
	            }

	            int result = -1;
	            try {
	            	result = context.getWiki().createUser(wikiname, map,  
parent, content, "edit", context);
	            	log.info("User " + xwikiUser + " created successfully.");
	            	userSuccessful = true;
	            } catch (Exception e) {
	            	log.error("Exception when creating user "+wikiname,e);
	            }

	            if (result!=1) {
	            	log.error("Creating user " + xwikiUser + " has failed  
with status "+result);
	            }

Is this REALLY necessary? The task of creating a new user can be  
achieved easier, surely?

Now I did have some code for checking if a given group exists, if not  
create it. Then check if the user is in the group
and of not, add him. All my attempts in this direction were rewarded  
with frustration. I find the data model (or perhaps
the abscence of cleaner structure for these things) highly obscure and  
impossible to penetrate without a proper form
of documentation.

Does such documentation exist? A few simple examples perhaps?
