[xwiki-devs] User rights !
by Kamna Jain 17 Apr '08

17 Apr '08

Thanks a lot Devs. You have been very helpful As an administrator, I see that rights can be assigned on a user basis and on a group basis. What are the rules for assigning these rights if an ordinary member (showing up in the users list) also belongs to a group. I am guessing that anyrights applied to the group automatically apply to all users in the group BUT they do not show up the indivdual users list ! Also, can a user be a member of more than one group ? I realized that just assignig the global rigths /user rights are not sufficient! Space rights also matter! Is there a way to assign edit/view rights for a group in any space. For example, if we take the Todo application. There the creator has an option fo choosing the space in which he wants to create a new Todo object. If the user chooses a space where he does not ahve edit/view rights, it's not going to work right! It throws error 9001. so, how can we ensure that groups get rights on the newly created spaces? On another note: I used the following in the HTML code for creating a form for creating a new object: Here I assign the parent of the newly created page as "Main" But, the page actually gets created in the XWiki space. Is this because the class I am using belongs to the XWiki space ? I understand that an Xwiki Page is actually an Object. But then how does XWiki allow one page to contain multiple objects at once (like commments and Tags etc...) Or did I understand it wrong? '<input type="hidden" name="parent" value="Main"/> <input type="hidden" name="template" value="HybridPublishClassTemplate"/> <input type="hidden" name="sheet" value="1"/> Thanks again Devs.

[xwiki-devs] What is $msg ?
by Kamna Jain 17 Apr '08

17 Apr '08

Hello Devs, In the past few days, I have been looking a lot at the Velocity templates and the Xwiki core code. There are a few things I am not able to understand. 1) Where is $msg variable defined in the core code? I see it a lot in the scripts. Is it a hashtable for messages. Where is it defined? 2) what is referred to by "xpage","xredirect" For eg. in the following mehtod from Utils.java public static String getPage(XWikiRequest request, String defaultpage) { String page; page = request.getParameter("xpage"); if ((page == null) || (page.equals(""))) { page = defaultpage; } return page; } does this mean, that if a page with that name exists in the template directory(xpage), it will be returned. But, what is defaultpage? Currently the login page does not show any error if the provided credentials are wrong. (authentication with LDAP) A look at the LoginErrorAction.java in the Web package revealed that it returns the same string as the LoginAction - "login" so, if I created anither loginerror.vm in teh templates folder and returned "loginerror" in the render function of this LoginErrorAction.java class, it would run the new script. But, at this stage I do not know what would be the content of the loginerror.vm.... #xwikimessageboxstart($msg.get("error") $msg.get("notallowed")) - would this work? I picked this up from accessdenied.vm ... Thanks for all help Thanks

[xwiki-devs] [VOTE] Using ThreadLocal vs passing the Context around for all method calls?
by Vincent Massol 16 Apr '08

16 Apr '08

Hi, In the new xwiki architecture we need to take a call for passing the request, response and session around (what is currently called the XWikiContext). We have 2 solutions: 1) we pass it around for all method calls as it's currently done 2) we use ThreadLocal(s). If you don't know what it is see for ex: http://crazybob.org/2006/07/hard-core-java-threadlocal.html . The advantage of solution 2) is that any component in the new architecture can decide to have the Container component injected (see http://svn.xwiki.org/svnroot/xwiki/xwiki-platform/core/trunk/xwiki-containe…) and thus be allowed to access the request, response and session objects without having all its method add a Container object passed to it. The downside of solution 2) is simply that we associate Unit Of Work with Threads. But since we use a Servlet model and since I don't see any foreseeable future where we would want to use several threads for the same unit of work, I don't think this is limitating for us. See http://blog.objectmentor.com/articles/2007/09/04/thread-local-a-convenient-… for some explanation on this. So right now and even though ThreadLocal sound a little bit "hackish", I think this is still my preference as it'll save us from having to pass Container objects everywhere. Since this is an important architecture decision I wanted to have a vote for it. Thanks -Vincent

[xwiki-devs] XWiki Classes and Properties
by Kamna Jain 16 Apr '08

16 Apr '08

Hello all, I went through the TodoClass tutorial and found it useful. I have a question regarding this functionality. Are these classes or the values of the properties for its instances saved in any table in the Xwiki database? Say, we use Classes and Objects to create a form that the user needs to create a document. Will the form values be saved in a database? How can we access the values of any instance of the created class? Also, how do we Delete a property from a Class definition? (If added by mistake while creating the class) Thanks for all help

[xwiki-devs] Encoding problem of UTF-8 wiki, especially with non-english URL
by LiDan 16 Apr '08

16 Apr '08

This is the second time I ask this question, because maybe last time I didn't describe it clearly. I hope someone can help me on this. I have created a utf-8 wiki and set Chinese as the default langauage. I met 3 main encoding problems: 1. When I created a link with Chinese name in a page also named in Chinese. I found that the ULR of the link was like" /xwiki/bin/edit/Main/%E6%B5%8B%E8%AF%951?parent=Main.测试&editor=wysiwyg", the main part is UTF-8 encoded, but the parent param is in original Chinese encoding, means two endcodings for one URL. The consequence was that when I clicked the link to edit the new page, the parent link is ill-formated, and could not find the correct parent. I checked this forum, and found that someone had met it before, but it was supposed to be resolved, see http://www.nabble.com/Non-ascii-characters-in-doc-names%2C-need-advices-for… This problem only in IE6 and IE7, in firefox it's OK, because in firefox only one encoding in the URL. I have tried both xwiki 1.2 and 1.3, same problem. 2. When I use export function, all the pages and spaces with Chinese name are ill-named in the xar pack. 3. On the logs in CMD window of XWiki, all the Chinese words can not display correctly. Please someone help me to fix the problems, many thanks. -- View this message in context: http://www.nabble.com/Encoding-problem-of-UTF-8-wiki%2C-especially-with-non… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Create a new Page with Velocity?
by Kamna Jain 15 Apr '08

15 Apr '08

Thank you Pascal, Ricardo for your inputs. We will wait for the demo. I have another Question. How can I use Velocity to create a New Page when I click on a link! The scenario is such that when new users use the system to publish certain information, they should be able to just click on one link from the Quicklinks panel and that should take them to a new page in edit mode with an Object from an already created class..basically simulating a form to be filled by the user! I saw XWiki.createDocument() in the XWiki API, but there is no way to specify the title of the new document. Please guide. Thanks
