manage_cutObjects/manage_pasteObjects problem ...
Hi all: Ive been trying to cut objects from one context and paste them into another using a script python. But I get a "CopyError" when I try doing this. This is my code snippet and the traceback ... Snippet... ... obj = context.restrictedTraverse(path) obj_parent = obj.aq_inner.aq_parent dest_folder = context.Dest # this is a folder object copy_info = obj_parent.manage_cutObjects((context.getId())) dest_folder.manage_pasteObjects(copy_info) ... Traceback: Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module OFS.CopySupport, line 194, in manage_pasteObjects Module OFS.CopySupport, line 527, in _verifyObjectPaste Copy Error: <HTML> <HEAD> <TITLE>Not Supported</TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF"> <FORM ACTION="manage_main" METHOD="GET" > <TABLE BORDER="0" WIDTH="100%" CELLPADDING="10"> <TR> <TD VALIGN="TOP"> <BR> <CENTER><B><FONT SIZE="+6" COLOR="#77003B">!</FONT></B></CENTER> </TD> <TD VALIGN="TOP"> <BR><BR> <CENTER> The object <em>dtmij.txt</em> does not support this operation. </CENTER> </TD> </TR> <TR> <TD VALIGN="TOP"> </TD> <TD VALIGN="TOP"> <CENTER> <INPUT TYPE="SUBMIT" VALUE=" Ok "> </CENTER> </TD> </TR> </TABLE> </FORM> </BODY></HTML> .... I cannot perform this operation directly using the ZMI also. So it is not a problem with the script. Some issue in CopySupport. I searched for the resolution and found that CopySupport needs to be patched. But I couldnt find the patch anywhere. My Zope is 2.9.4-final, Python2.4.3. Any help is greatly appreciated.

I think the problem is your 4th line: copy_info = obj_parent.manage_cutObjects((context.getId())) copy_info should be the object you want to cut it should be something like this: ... src=context.your_cut_context[obj_id] context.your_cut_context.manage_cutObjects([src]) dst=context.your_paste_context dst.manage_pasteObjects(src) ... Let me know if it works for you, Giampiero

Sorry Giampiero, you're just guessing, and you're guessing wrong. The original poster's code was correct*. Dieter's suggestion is a better approach to troubleshoot this problem. *well, almost correct. There's a common Python mistake on one line: copy_info = obj_parent.manage_cutObjects((context.getId())) ^^^^^^^^^^^^^^^^ You think you're creating a tuple there, but you're not. To create a tuple of size 1, you need a trailing comma: copy_info = obj_parent.manage_cutObjects((context.getId(),)) But that's not causing your problem; manage_cutObjects() "helpfully" wraps a string argument in a tuple for you. -- Paul Winkler http://www.slinkp.com

"manage_cutObjects" takes a sequence of ids (or a single id) as input (not the real objects).
dst=context.your_paste_context dst.manage_pasteObjects(src)
"manage_pasteObjects" takes the return value of "manage_cut/copyObjects" as input not the real objects. -- Dieter

Usually, Zope error messages and tracebacks are quite informative. The unhelpful error messages from "CopySupport" are an exception. For them, you must look at the Code (near line 527 of "CopySupport.py") and check, what it really did not like. -- Dieter
