Hi list, I have Zope installed using the following config: Zope 2.9.4-final, python 2.4.3, sunos5 I´d like to export an object which has several children. Using the web management console, I navigate to the root folder and checked the checkbox for the object to export. After that, I clicked the export/import button. The object ID showed up correctly, so I clicked the export button, wanting to leave the export file on the server. The export seemed to work. At least, I found a file on my server. Unfortunately, the only content of the file was one line: ZEXPÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ The file itself is only 20k of size. Is there something I missed? Is there probably a command line tool to do exports? Thanks in advance. Best regards, Chris

And? What did you except? What should it contain? It contains a binary format - to be exactly: the Python pickle of the selected object. -aj
Hi again, sorry - forgot to mention: I actually wanted to export the object and all its children recursively so that I have a complete backup of the content. The use case is to move the content from one server to another. Thanks once again for helping and best regards, Chris Andreas Jung schrieb:

And? The zexp format is a binary format and can be re-imported into another Zope instance (running the identical Zope version). Where is the problem? -aj
Hello Andreas, hi list, unfortunately, the zexp-file does not contain any of the children objects. Re-importing the zexp-file leads to the following error: Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: 'NoneType' object has no attribute 'id' Sorry for asking, but I?m quite new to Zope. Thanks once again and best regards, Chris Andreas Jung schrieb:

How will you know that when your import fails? And export operation always exports always the object including its whole subtree (if the object is an folder). So basically I would not believe that what you're saying.
Re-importing the zexp-file leads to the following error:
Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: 'NoneType' object has no attribute 'id'
You must provide the _full_ traceback. -aj

And export operation always exports always the object including its whole subtree (if the object is an folder). So basically I would not believe that what you're saying. The object, I?d like to export is a folder. At least, it shows up with the corresponding icon. In the navigation frame on the left, the folder is visible with a "+" in front of the symbol. Clicking the "+" uncovers a list of sub-objects. Puzzling is that selecting the folder or one of the sub-objects by clicking it, the content is viewed at once, not the "manage_workspace" view.
Re-importing the zexp-file leads to the following error:

Which Zope version are you running? Which 3rd-party products are you runngin? Are you sure that the source and destination system have *IDENTICAL* software versions (same Zope, same Python, same 3rd-party products)? -aj

The version information shows: Zope 2.9.4-final, python 2.4.3, sunos5 I tried to re-import the renamed export file to the same server, so it?s the same version. I?m not aware of any 3rd-party components. The Products subtree in Control Panel does not show anything unusual. Thanks, Chris

No idea, never seen that. -aj

unfortunately, the zexp-file does not contain any of the children objects. Re-importing the zexp-file leads to the following error:
We need some more information as to the type of object you are trying to export (eg. folder, ZClass instance, custom product instance, etc).

Include the full traceback. Jonathan

All you can do via the ZMI, you can do in an interactive Python interpreter session -- however, it is unlikely that the result will be different. "Export" uses essentially the same mechanism which is used by the ZODB itself (persistent references are expanded, though, rather than stored as references). Especially, the export of an object should contain all objects referenced (directly or indirectly) by this initial object. If this does not work in your case, then it may be necessary to debug the export process (to find out why it does not work). -- Dieter

Hi Dieter, thanks for the reply. I set the log levels to debug and got the following results in event.log: 2007-08-10T15:05:06 DEBUG txn.4 new transaction ------ 2007-08-10T15:05:06 DEBUG ZODB.ExportImport broken reference for oid '\x00\x00\x00\x00\x00\x00\x00\x06' Traceback (most recent call last): File "/ra1/roteliste_2007-08/lib/python/ZODB/ExportImport.py", line 45, in exportFile p, serial = load(oid, self._version) File "C:\Programme\RoteListeIN\Products\RoteListeIN\CdromStorage\CdromStorage.py", line 673, in load TypeError: exceptions must be classes, instances, or strings (deprecated), not NoneType ------ 2007-08-10T15:05:07 DEBUG txn.4 commit Unfortunately, from the logs I really cannot see what to do. Does anyone know? Any help is appreciated. Thanks in advance. Best regards, Chris

The traceback tells you that there is a bad exception use in ".../CdromStorage.py" line 673. "CdromStorage" does not belong to the Zope core -- and I do not know anything about it. Check the code and find out what goes wrong near line 673. -- Dieter
