Object serialization between different pages
by Pierre-Julien Grizel 12 Sep '00

12 Sep '00

Hi, Is it possible to serialize an object to share it across several pages ? This would allow one to pass the serialized object via the URL, and to retreive it in the form that would process the request. I know there is the pickle function in python, but is there a more Zopish way to do this ? Thanks, P.-J.

by Jean Jordaan 12 Sep '00

12 Sep '00

Hi all If I ftp a bunch of zwikipages out of the ZODB, each one has this:: Wiki-Safetybelt: 968246577.617 What is is, and do I need to keep it if I want to ftp them back in? The thing is, I 'diff'ed and 'patch'ed two wikis against each other, and I'm not interested in changes that involve only the the Wiki-Safetybelt. I'd appreciate it if you Cc: me on answers ..

Hi to all, anyone know how to let Zope interact with text files on the system on it is running. Like making changes to files, search and replare some text or insert or delete text and save the file again? I'm pretty new and i don't know if it is possible for Zope. Thank You in advice. Marcello

dtml-in theentiresite

In the root.... A DTML Method.... Some objects (mostly DTML Documents) have a property (boolean) that tells whether this is a helppage or not. What I want to do is to loop though eash and every object in the entire site (not very big) and check if the object has this property. <pseudo code> <dtml-in "objectItems(['*'])"> <dtml-if ahelppage> <a href="<dtml-var id>"><dtml-var document_title></a> </dtml-if> </dtml-in> Any other good solutions are welcomed!

Manager Authentication Failure: How to debug?
by Kimmo Kansanen 12 Sep '00

12 Sep '00

Hi all, I just installed the latest Zope available for Debian (2.2.1) on Potato. However, after logging in as superuser and creating the manager account, I cannot log in with that account. The logs produced (that I found) only indicate the ZServer getting the http request, but nothing on the authentication failure. How should I proceed debugging the problem?

Albert, I've put this in the collector as a possible bug... hopefully it will get fixed with the next release if it proves not to be the proper behavior. In the meantime, you want want to try messing around with that regex to get the appropriate behavior for your environment. aboulang(a)ldeo.columbia.edu wrote: > > I've done a little poking around in ZPublisher's HTTPRequest.py and > BaseRequest.py and I don't think that's where the ';*' gets stripped.

Re: [Zope] Using Chinese Characters
by icottee＠bluefountain.com 12 Sep '00

With reference to inputting chinese characters I have similar issues within handling Japanese. My two solutions are either use Internet Explorer (if you have a windows machine) and use their add on extensions (download 5.5 and look at the extra options during download setup) or use emacs with MULE. Obviously there are limitations with the emacs method with what you can and can not edit. Some distributions of Linux will allow you to setup your environment in both Japanese and English and toggle between the. I think the same is true for Chinese. Try Kondara at http://www.kondara.com - I saw a demo of their new version at the Linux Expo which seemed to work well. Apart from playing with a Japanese distribution for fun I haven't done any serious work with these. Note that if you ever want to start storing your characters in external databases you will need to make sure that it can handle your encoding as well. MySQL has to be compiled with a certain config flag and I believe the same is true with Postgres. Otherwise strange things will happen :-) Ian
