by Maik Jablonski 26 May '05

26 May '05

Hi, I've just released Epoz 2.0.0. Main new features are: - You can now use several Epoz-Wysiwyg-areas on a single page at once. This feature was often requested (esp. for use with Archetypes) and Benoit Pin did a really great job on making this real. Many, many Thanks, Benoit! Never thought that this was possible at all...;) Sorry, it took so long to roll the things out on my side... - The customizing of the Toolbar should be easier now with CSS. - Several other fixed stated in the CHANGES.txt (!!! Please read it before updating Epoz!!!) Download Epoz at: http://mjablonski.zope.de/Epoz Demo (with two widgets at once): http://www.zfl.uni-bielefeld.de/personal/mjablonski/epoz Keep zoped, Maik

Re: [Zope] Zope 2.7.2 with Ape 1.0 installed in root, fails to restart, without any usefull logging, after adding a local role
by Tim Connor 26 May '05

Thanks, Shane. That fixes the problem of Zope not starting, and better than the other syntax I tried, but it still doesn't fix the core problem. My root Ape installs have issues with adding a local role, as then the default roles get axed. If you add this fix then Zope re-adds Owner (and Authenticated, as you need to duplicate the fix a couple lines lower) during the start-up, but not Manager - and they are not really added, but sort of hacked in by the start-up code. Shouldn't Ape be somehow dealing with this exact situation anyways, or is there just something wrong with my installs?

Still. Zope date datatype and TimeZone formatting problems.
by Felipe Barousse Boue 26 May '05

26 May '05

Zopistas: I am experiencing the same problem you described by Mr. Hong Yuan in his post a few from last March. I have Zope 2.7.4, python 2.3.4 and PostgreSQL 8.0 and psycopg as DB adapter. All my dates stores in postgresql are WITHOUT timezone and my linux is set for the "America/Mexico City" time zone. All works fine at the OS and python level but not within Zope, it behaves as Mr. Hong Yuan describes in the post. I have noticed that Zope, when getting the data coming from postgresql (the date) always takes it to be at midnight in GMT time zone. While formatting the date for presentation, it doesn't take into account the OS TZ settings, it just assumes data (from postgresql) is at midnight in GMT and mangles it. If the TZ variable is set on the zope.conf file, it actually adds hours to the date (as like moving east), having first during the day having the "date ok" but a wrong time and, later on the day, the date goes wrong because of that timezone difference. If the TZ is not set in the zope.conf file it substracts hours from the date data from postgresql, effectively moving the date on day before, because it assumed midnight GMT. Doing further experiments I have noticed that when the data type passed to Zope is "date" (not "datetime" or "timespamp", only date) then Zope misbehaves with the TZ, assuming it is on GMT and not taking into account the overall system (Operating system) time zone settings. I have seen posts discussing this issue as far back as 2001. Has it been solved already ? Is it worth getting into the Zope code and trying to fix it and submit a patch ? Or its already deprecated ? or...? I believe it is still a huge bug the the Zope/Python date time handling routines, I am correct with this appreciation? Any comments are most than welcome.

Using LocalFs in a form embedded in our application
by Simon ALEXANDRE 25 May '05

25 May '05

Hi, We are developing a web based application using Zope as webserver. One of our expected features consists in uploading a zip file on the server and after that to unzip it. Our pages are designed using zpt. I would like to include in one of my pages a simple form allowing to select a file in the client machine and to upload it on the server (in a dedicated directory, not in the zope DB). I have installed LocalFS. I try with a form like that in my code (copy/paste from the source code provided by localFS in zope): <form action="manage_upload" method="post" enctype="multipart/form-data"> <input type="file" name="file" size="25"/> <input class="form-element" type="submit" value="Add"/> </form> But nothing happen when I clic on the 'add' button. No upload, no error. NB: this form is encapsulated in a macro (already encapsulated in a form), is it the cause of the problem? Someone have an idea?? Thanks in advance Here is the source code of the macro which encapsulates the form: ---------- <tr metal:define-macro="Macro_ImportFileSystem"> <td colspan=5> <table cellspacing=0 cellpadding=0 width="100%" align="center"> <tr height="10px"><td/></tr> <tr> <td align="center"> <table cellpadding=0 cellspacing=0 width="350px" align="center" tal:define="paths here/GetCurrentFolderContent"> <tr><td colspan=3>Files and/or folders to import<img src="Images/Mandatory"/></td></tr> <tr height="3px"><td colspan=3/></tr> <tr height="1px" bgcolor="#CCFF60"><td colspan=3/></tr> <tr height="25px"> <td colspan=3> <input type="image" src="Images/ParentFolder" name="gui_OnChdirpp" style="border-width: 0;background-color:#FFFFFF;width: auto;height: auto" tal:condition="python: (session['projectCurrentFolder'] not in ('/', '\\')) and (session['user'] != 'anon')"/>  You are in <span tal:replace="session/projectCurrentFolder">Current dir</span> </td> </tr>  <tr> <form action="manage_upload" method="post" enctype="multipart/form-data"> <input type="file" name="file" size="25"/> <input class="form-element" type="submit" value="Add"/> </form> </tr>  <tr tal:repeat="path paths"> <span tal:define="rowBgColor python:here.Shared.GetInfo('rowColor', paths.index(path))"> <td tal:define="pathType python: here.GetPathType(path[0])" tal:condition="python: session['user'] != 'anon'"> <input type="image" style="border-width: 0;background-color:#FFFFFF;width: auto;height: auto" tal:condition="python: pathType == 'Folder'" tal:attributes="src python: 'Images/%s' % pathType; name python: 'gui_OnChdir_%s' % path[0]"> <img tal:condition="python: pathType != 'Folder'" tal:attributes="src python:'Images/%s' % pathType"/> </td> <td tal:attributes="bgcolor rowBgColor"> <input type="checkbox" tal:attributes="style python:'border-width: 0;;background-color:%s' % here.Shared.GetInfo('rowColor', paths.index(path)); checked python:here.IsInImportInfo(path[0]); name python:'cbfc_'+path[0]; disabled python:session['user'] == 'anon'"> </td> <td tal:attributes="bgcolor rowBgColor" tal:condition="python: path[1]" tal:content="python: path[0]" width="100%"> </td> <td tal:attributes="bgcolor rowBgColor" tal:condition="python: not path[1]" tal:content="python: path[0] + ' [removed]' " width="100%"> </td> </span> </tr> <tr tal:condition="not: paths"> <td colspan=3><i>The folder is empty.</i> </td> </tr> <tr height="3px"><td colspan=3/></tr> <tr height="1px" bgcolor="#CCFF60"><td colspan=3/></tr> <tr tal:condition="python: session['mode'] == 'Update'"> <td colspan=3 align="right">Do not update files and folders  <input type="checkbox" name="pjIgnorePaths" style="border-width: 0;background-color:#FFFFFF" tal:attributes="checked session/projectKeepOriginalInfo; disabled python:session['user'] == 'anon'"> </td> </tr> </table> </td> </tr> </table> </td> </tr> Simon ALEXANDRE

How to use ParsedXML
by Jason Leach 25 May '05

25 May '05

hi, If I have a ParsedXML document with the following: <?xml version="1.0"?> <faq title="A Sample FAQ"> <entry> <question>To be or not to be?</question> <answer>That is the question.</answer> </entry> <entry> <question>The question of life the universe and everything?</question> <answer>42</answer> </entry> </faq> >From a page template, how to I access the questions and answers? So I can start displaying the XML document content. I tried various forms of: <p tal:content="here/myxmldoc/entry/question"></p> I'd also like to use it through acquisition if possible. Make a method that views and entry and then call in on my document? But no luck. Thanks, Jason.

ZSyncer and ZEO
by Dennis Allison 25 May '05

25 May '05

Does ZSyncer have any problem with Zope/ZEO systems? I have some anecdotal evidence of problems as we migrate to a multiheaded Zope/ZEO systems architecture. Is there any difficult using ZSyncer between a Zope and a Zope/ZEO combination. Are there problems syncing between Zope 2.6.X and Zope 2.7.X systems? All the systems run ZSyncer 0.5.1.
