New subject: [xwiki-users] [xwiki-devs] Questions about Blog Example

Hi, Anca,

Thanks very much for your response, I understand how data are saved to
database now, but I got another question:

 In the following code from BlogPostSheet
<dl>
  <dt>$msg.get('xe.blog.sheet.title')</dt>
  <dd>$doc.display('title', 'edit', $entryObj)</dd>
  <dt>$msg.get('xe.blog.sheet.content')</dt>
  <dd>$doc.display('content', 'edit', $entryObj)</dd>
  <dt>Feature ID:</dt>
   <dd>$doc.display('FID', 'view', $entryObj)</dd>
  <dt>Package ID:</dt>
    <dd>$doc.display('PID', 'view', $entryObj)</dd>

  <div class="clearfloats"></div>
  </dd>
  </dl>

If I change the 'view' to 'edit' for both FID and PID, then both of FID
and
PID will be saved to database, and I can query retrieve them, but I have
use view, then they are not saved to database. the problem is I donot want
these two fields editable, so I have to use view, any workaround for this?
so the bottom line is I want them to be saved to database and not editable
from the inline form.

Thanks again for your help.

Dave

  Hi Dave,

 You should read http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**
 Architecture<http://platform.xwiki.org/xwiki/bin/view/DevGuide/Architect…re>, but I
understand that it might be cryptic for a first time usage so here
 we go:
 must know that xwiki is a java engine, so there is some java code that
 does things, it's not all done in velocity.
 Basically, there is a java "platform" that can handle documents, objects
 in documents, classes, etc (load, save) and then there is the velocity
 scripting that you can do in wiki pages which **uses** this core (injected
 variables like $xwiki, $doc). See here about how this scripting in pages
 works:
http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**Scripting<http://p…ng>.
 Also, there are some interesting information about the data model here

http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**DataModel<http://p…el>.

 The 'platform' project on git contains all this 'platform' code: java
 sources, default templates, default js, css, etc, which you can enhance in
 wiki pages (but we don't do everything in wiki pages, so you should not
 look for it only in wiki pages).

 Also, there are a bunch of "default" velocity templates that handle the
 default layout and actions for the wiki (in the webapps/xwiki/templates
 folder of the installation). For example, the save and view button is
 generated by these templates, along with the url to which the data in the
 form is posted.

 I recommend firebug and LiveHttpheaders extensions of firefox to study
 what data is posted to which URL, etc what data is received. from then on,
 with the help of http://platform.xwiki.org/**xwiki/bin/view/DevGuide/**

Architecture#**HUnderstandinghowHTTPrequestsa**rehandled<http://platform…ed>,
you should be able to find the code that actually does the save.

 Have fun,
 Anca

  Also from the following BlogPostSheet wiki code,
after users type in
 message from the inline form, users click Save&  View button, how are the

 messages saved to database?
 see the attached code:
 {{include document="Blog.BlogCode"/}}

 {{include document="Blog.CategoriesCode"**/}}

 {{velocity filter="none"}}
 {{html clean="false" wiki="true"}}
 $xwiki.jsx.use('Blog.**ManageCategories', {'mode' : 'select'})##

   #warning($msg.get('xe.blog.**sheet.notpost'))
 ## Keep testing the inline action for backward compatibility with older
 blog posts.
 #elseif($xcontext.action != 'edit'&&  $xcontext.action !=
'inline')
   ## View mode
   #isPublished($entryObj $isPublished)
   #isHidden($entryObj $isHidden)
   ## displayBlog requires a list of documents, and whether to display only
 an extract or the full entry.
   #displayBlog([$tdoc] 'single' false false)
 #else
   <dl>
   <dt>$msg.get('xe.blog.sheet.**title')</dt>
   <dd>$doc.display('title', 'edit', $entryObj)</dd>

   <dd>
   #**displayCategoryManagementTree(**'' 'selectable')
   <div class="clearfloats"></div>
   </dd>
   </dl>
   #template('tagedit.vm')
   #isPublished($entryObj $isPublished)
   #if($isPublished)
     #if($doc.creator == $xcontext.user)
       #publishMessageBox($msg.get('**xe.blog.sheet.publicationdate'**,
 [${doc.display('publishDate', 'view', $entryObj)}]))
       #set($hideArticle = ${doc.display('hidden', 'edit', $entryObj)})
       #hideMessageBox($msg.get('xe.**blog.sheet.hidearticle',
 [${hideArticle}]))
     #end
   #else
     #set($defaultDate =
 $xwiki.getDocument($**blogPostTemplate).getObject($**blogPostClassname).*
 *getProperty('publishDate').**value.time)
     #if($entryObj.getProperty('**publishDate').value.time ==
 $defaultDate)
       ## The publish date was not set, force it to be the creation date
       $entryObj.set('publishDate', $doc.creationDate)
     #end
     #publishMessageBox("$msg.get('**xe.blog.sheet.notpublished')

   #end
 #end

  Hi, all

 I am studying the BlogClass, BlogPostClass, I checked the Blog.BlogCode,
 there are alot of velocity scripts, I can see the search documents from
 db,
 but could not find any code related to insert document records into
 database, so how is the document created from blog saved into database?
 please point me to the script code in the Blog.BlogCode.

 Thanks

 Dave
