Subject: RE: [xwiki-users] "Clone" another documents objects when creating a new document

Jeremie (and Ludovic):

 

I don't know whether this has been fixed yet, but in 0.9.840 if you copy a user's profile page (the one created by XWiki.createUser()) the object copy fails silently (transaction aborted).  If your code examines the copied document immediately from the same session, without clearing the cache, it looks right, but after calling $xwiki.flushCache(), or viewing the document from any other session, only an empty template shows, with no XWiki.XWikiUsers object to display and no XWiki.XWikiRights objects.

 

The object copy fails because one of them - the XWikiRights object for XWiki.XWikiAdminGroup, which was created by XWiki.ProtectUserPage() when the user was created - contains a field "levelsye" which is not in the current schema for objects of class XWiki.XWikiRights, which names the field "levels" instead.  And it also doesn't matter if the user was created by your wiki instance after installation or if it came built-in with the database installation; the default users are also corrupted this way.

 

I must apologize:  I probably should have filed a bug on this, but I didn't.  It wasn't initially clear to me what the status of it was, and since the job I was trying to do was my major priority, I didn't take the time to find out.  But I think it's two bugs - actually three from the standpoint of the delivered product - because the database load contains the result of one of the errors in the code:

 

 - first, the root cause:  XWiki.ProtectUserPage creates an XWiki.XWikiRights object with a "groups" field with value "XWiki.XWikiAdmin", a field named "levelsye" with the value from its userRights parameter, and "allow" value of 1.  This object cannot be copied to another page, because the "levelsye" field is not in the current schema for XWiki.XWikiRights.

 

 - second:  the 0.9.2 database upload contains the result of this problem in all of its built-in user profile documents.  I had thought that this was the source of the problem, and that all new users simply had the defective rights object copied from one of those, until I discovered the above problem.

 

 - finally, the resulting problem that I had when changing XWiki's authentication scheme, which required existing users to be renamed:  When the attempt (within XWiki.copyDocument()) to add the new object to the new document fails because of the above, no error indication is given, and the document copy transaction doesn't abort, roll back or return a failure status. Moreover, the cache (at least for the current session) now holds a copy of the new document, composed as expected, so any attempt by the calling page to verify the copy without first flushing the cache seems to succeed.

 

I think I asked whether my characterization of this problem was correct, but didn't get a response.  Probably I should simply have filed it as a bug and let the developers correct me if I was wrong.  To avoid a problem of this sort in the future, I think that perhaps the best protocol would be that I file it unless someone objects; that would make sure that it was accounted for.

Hello,

 

I believe you can use the copyDocument() method. I use it to rename pages, I copy a document to a newly named document, then delete the old one.

All objects and attachments are also copied in the process, so that may interest you (as far as all objects are included in the template document I believe)

 

$xwiki.copyDocument($sourceDoc, $targetDoc)

Subject: [xwiki-users] "Clone" another documents objects when creating a new document

Hi All,

Is there any way to clone all objects in an existing document to a different document with one server request?
So that a template document can be maintained with default object values; and can be brought in painlessly to a new document.
