No matter what you decide, some people will be unhappy. Unless there's an overwhelming majority in favour of change, leaving things as they are is usually the better bet. Aside from all that - if it really bugs you to see the list name in the subject line, tweak your mailer to hide them.

Can't you use os.path.getmtime('path_to_file') to get the modification time of the file and reparse and reinsert it only if getmtime >= old_getmtime? cheers, oliver

Some mathematical problems ...
by Gitte Wange 10 May '01

10 May '01

Hello ... I don't know if I can explain it clear enough but here goes: I am trying to update to values in a database. The values are a priority number, used to sort a list by. My code looks like this: <dtml-call expr="sqlUpdateServerAbove(id=id, priority=priority+1, ServerNetid=ServerNetid, oldpriority=_.int(REQUEST.oldpriority)-1)"> The id-variable and the priority-variable comes from another sql-query and works just fine. The ServerNetid-variable and the oldpriority-variable are passed from a form. Now when this script is called it updates the record that comes from the other sql-query, but not the record that comes from the form (the best explanation I can come up with). So I guess it is because the oldpriority=_.int(REQUEST.oldpriority)-1) doesn't work. The values (before the <dtml-call>-statement is: id=1 priority=1 ServerNetid=2 oldpriority=2 When the script has been called the values are: id=1 priority=2 ServerNetid=2 priority=2 (and this should be 1) Anyone with a good idea ??

silly IE display question - manage screens showing 'view', not co ntents
by Meilicke, Scott 10 May '01

10 May '01

I'm using IE 5.5, win2k as a client, and when I enter a management screen, the right hand frame shows the 'view' of the object I select in the nav pane instead of the contents of that object. As a result, I cannot do much in zope. This works fine in netscape. Any thoughts on how to correct this? Thanks - Scott

Batch-adding images with extra attribs
by Etienne Labuschagne 10 May '01

10 May '01

Hi there I have a lot of images that I must upload into Zope. I can probably use FTP, but I have another problem. I add a copyright attribute to each image. It would be great if I can tell Zope, upload all images in directory c:\foo and give them a copyright attribute of bar. I have access to the server on which Zope is running, so it will probably be the easiest to write an external Python method to do the uploading from the server's file system. My question is, how do I upload an image directly from disk into Zope? Thanks in advance. Etienne

Get attributes of a doc in another folder
by Gilles Lenfant 10 May '01

10 May '01

Hi from a newbie, I got a dtml method at "/project" folder from which I want to add attributes to a dtml doc at "/project/folder/adocument" I tried to embed 2 consecutive <dtml-with> like following but it don't work. Did I miss something ? <dtml-with folder> <dtml-call "manage_addDTMLDocument(id=aname,title=prenom+' '+nom,file='')"> <dtml-with expr="aname"> <dtml-call "manage_addProperty(id='alias',value=alias,type='string')"> </dtml-with> </dtml-with> This adds the attribute to folder when I want it in adocument . I'm lost somewhere... TIA Gilles

ANN: zupdate.py - synchronize multiple distributed Zopes
by Thilo Ernst 10 May '01

10 May '01

Hello, fellow Zope users: as the number of Zope installations I'm working with showed some growth recently (besides a production, a development and a test server I set up an experimental installation from time to time as well) - I got tired of manually distributing stuff from the development site to the other ones using Export, then ftp or scp, then Import. A search on zope.org didn't reveal much prior art, just that a 'Synchronizable Objects' and a 'Synchronization tab' seem to be planned for future Zope releases. (If someone knows a suitable existing tool nevertheless, please send me a note.) Thus, I decided to write something on my own. Here is the the result: http://www.zope.org/Members/te0006/zupdate.py zupdate.py is a stand-alone Python (1.52 or higher) script fot updating selected objects on one or more remote Zope instances from a local 'master' (e.g. development) site. It works by: - making the local ('master') Zope instance export the selected objects to a set of .zexp files - transferring the .zexp files to the remote server(s) via scp (the secure variant of rcp that comes with ssh) - re-importing the objects to their appropriate locations in the remote Zopes' object hierarchy All Zope servers can remain 'live' all the time as the Import/Export actions are invoked via HTTP. The .zexp files are automatically grouped so scp will be invoked (and will ask for authentication) only once per remote server. Their collection and transfer is also done using synthetic filenames to avoid name clashes. zupdate.py expects as a command line argument a task description file containing a set of Python statements which describe the local and all remote Zope instances (URL, username/password for administrator, Zope root directory in filesystem), and which objects to transfer. Invoking zupdate.py without parameters provides detailed information about the structure of the task description. A sample task description file is appended to this mail. zupdate.py was tested on a Linux 2.2 i386 system (RH 7.1) but should be able to run with minor changes on any system where Python 1.5.2 (or higher) and scp are available; of course, the remote servers must have ssh/scp as well. IMPORTANT NOTE: This script is hardly more than a quick hack. Even though it did work for me, it will likely have bugs. Every conceivable standard disclaimer applies. You cannot hold me liable for anything. Use at your own risk. License: Python-style. Best regards, Thilo Ernst # SAMPLE TASK DESCRIPTION FILE # no real hostnames & administrator credentials, sorry # local Zope installation LZOPE=( 'localhost:8080', ('adm', 'adm42'), '/ZOPE/Zope-2.3.1b2-linux2-x86' ) # remote Zope installation, or list thereof RZOPE= [ # test site ( 'test1.zopecentral.org:8080', ('Administrator1', 'Secret'), 'testuser@test1.zopecentral.org:/ZOPE/Zope-2.3.1b2-linux2-x86'), # production site ( 'www.zopecentral.org:80', ('Almighty', 'TopSecret'), 'zopeuser@www.zopecentral.org:/ZOPE/Zope-2.3.1b2-linux2-x86') ] # objects to be updated, optionally with deviating target folders OBJS= [ ('/myfolder/obj1', '/yourfolder'), # different folder in target Zope instance '/ourfolder/obj2' # same folder ]

ZopeTime() in python script ...
by Mike Blake 10 May '01

10 May '01

Hi! I have a messy dtml block that returns a yyyymmdd date string using zope time: # <dtml-var "(ZopeTime()).year()" # ><dtml-if # expr="(ZopeTime()).month()<10" # >0<dtml-var "(ZopeTime()).month()" # ><dtml-else # ><dtml-var "(ZopeTime()).month()" # ></dtml-if # ><dtml-if # expr="(ZopeTime()).day()<10" # >0<dtml-var "(ZopeTime()).day()" # ><dtml-else # ><dtml-var "(ZopeTime()).day()" # ></dtml-if> This works, BUT I would like to forget the dtml and just write it in python. Something like this?: # str="" # str = str + ZopeTime().year() # if ZopeTime().month()<10: # str = str + "0" # str = str + ZopeTime().month() # if ZopeTime().month()<10: # str = str + "0" # str = str + ZopeTime().day() # return str But this gives an error: Error Type: NameError Error Value: ZopeTime I have this as a python script object and although it would return a string ok, I get an error when trying to access ZopeTime(). I am currently losing my mind trying different arguments and import statements, but getting nowhere fast. How do I access the variables and methods (those that would normally be available to a dtml method) in a python script? thanks, mike -- [morcilla(a)ketden.com chikoon]$ whoami Mike Blake

Packaging (final) Zope book for Debian
by Andreas Tille 10 May '01

10 May '01

Hello, formerly I was able to check out Zope book beta from CVS via cvs -d:pserver:anonymous@cvs.zope-book.sourceforge.net:/cvsroot/zope-book login cvs -z3 -d:pserver:anonymous@cvs.zope-book.sourceforge.net:/cvsroot/zope-book co zope-book It seems that the modulname has changed in CVS from zope-book to Book. I managed to build a Debian package from the state of April 10th and didn't checked out CVS repository since then. Now I wanted to build the package from the final source. Is there any final source release? Which source is the best one for a Debian package? Kind regards Andreas.
