no accounts in root user folder?

Hello, I have a zope app in a folder and have an exUserFolder in there to authenticate the app's users. The app is working fine and i get authenticated by the exUserFolder and everything works. I tried to delete the single "admin" account (with Manager privileges) from the root standard user folder and the app breaks with: Unauthorized: You are not allowed to access 'call_backend' in this context where 'call_backend' is an External Method called by a Python Script. All objects in zope are owned by the "admin". Could this be causing the problem? Thnx for any help, Vangelis

PUT_factory and File object?
by Eric Fernandez 10 Aug '06

10 Aug '06

Hi, I am trying to upload text files as File objects instead of DTML documents to avoid HTML escaping. What is the type of the File object in Zope ? The example in the Zope book are ZopePageTemplate and PythonScript objects,, but I just want a File object. This does not work: def PUT_factory( self, name, typ, body ): if typ.startswith('text'): ob = File(name, body) return ob Which is the correct syntax? Where can I find the list of available objects in Zope and their attributes? Thank you, Eric

Using eggs in a Zope instance
by Anton Stonor 10 Aug '06

Python eggs are fun and powerful. However, there is one thing I can't get right when using them for Zope projects: Sometimes I would like eggs to live in $INSTANCE/lib/python instead of site-packages. E.g. if different instances needs different versions of a package. However, easy_install won't install them there, because $INSTANCE/lib/python is not in the PYTHONPATH. And I don't want to extend PYTHONPATH to include all my $INSTANCE/lib/python's -- that would prevent the different version pr. instance approach. How does you egg front runners deal with this? I'm on Windows if that matters. /Anton

> You must call manage_renameObject on the object *container*, passing the old name and the new name. Something like this: > object = result[1] > container = object.aq_parent > container.manage_renameObject(object.id, object.id.lower()) Thanks Gabriel. I did exactly as you suggested, but ran into this error : ///////////////////////////////////////////////// The id "begin" is invalid - it is already in use. ///////////////////////////////////////////////// "Begin" is the first activity. It could be some reserved word within OpenFlow or Zope - not really sure. In any case, I tried skipping it, but ran into another error message saying : /////////////////////////////////////////////////////////////////////// The object RECEIPT_OF_SOURCE_DOCUMENTS does not support this operation. /////////////////////////////////////////////////////////////////////// My code looks like this : //////////////////////////////////////////////////////////////////////// / wf = container.GeneralWorkflow catalog = wf.Catalog results = catalog.ZopeFind(wf, obj_metatypes=['Activity'], search_sub=1) for result in results: print result[1].id if result[1].id <> 'Begin': object = result[1] container = object.aq_parent container.manage_renameObject(object.id, object.id.lower()) return printed //////////////////////////////////////////////////////////////////////// / Regards, Danny

> Huh? Usually you have no chance to create a Zope object with such an id. > So there is no need to rename something that can't exist be definition :-) Exactly. The said object, "s5/Begin", is the "Begin" activity of the "s5" process found in the "GeneralWorkflow" workflow - which is an OpenFlow ( www.openflow.it ) object. I was able to rename my processes (S5, S100, S200) to their lowercase counterparts since all I had to do was do : /////////////////////////////////////////////////////// wf = container.GeneralWorkflow catalog = wf.Catalog processes = catalog.ZopeFind(wf, obj_metatypes=['Process'], search_sub=1) for p in processes: wf.manage_renameObject(p[0], p[0].lower()) /////////////////////////////////////////////////////// When I try to rename the activities found in those processes, I try to do likewise, but the ZopeFind results come out like this : ('S100/Begin', <activity at /dev/danny/wms/GeneralWorkflow/S100/Begin>) ('S100/RECEIPT_OF_SOURCE_DOCUMENTS', <activity at /dev/danny/wms/GeneralWorkflow/S100/RECEIPT_OF_SOURCE_DOCUMENTS>) ('S100/CHECK_MS_BATCHING', <activity at /dev/danny/wms/GeneralWorkflow/S100/CHECK_MS_BATCHING>) To call manage_renameObject (), I have to supply it with the object name. If I use result[0], I get the illegal characters in URL error. And if I use result[1].id, I get : Error Type: AttributeError Error Value: Begin This is probably because there is no "Begin" object under the "wf" container from which I'm calling manage_renameObject(). So my question is, how do I refer to the "Begin" object found in the S100 workflow ? Regards, Danny

> Because '/' is a reserved character since it is used in URLs as path separator. Any workarounds ? Is there a way to refer to the said objects without using the '/' ?
