If you use Frames (ick), it might be possible to have more than one tree. Unfortunately, you couldn't depend on the default cookies to hold the independant tree states correctly. Otherwise, no - only one tree per page. Sorry. - Ian C.

How do I accommodate two trees in one document?

I'm trying to make a navigationpage consisting of two trees with a <hr> between them. Here's the offending code snippet: <dtml-tree branches_expr="objectValues(['Folder'])" single=1 sort=title> <IMG SRC="<dtml-var icon>">  <a href="<dtml-var tree-item-url>" target="MainWindow"><dtml-var title></a> </dtml-tree> <hr width="90%" align="left"> <dtml-tree endusermisc branches_expr="objectValues(['Folder'])" single=1 sort=title> <IMG SRC="<dtml-var icon>">  <a href="endusermisc/<dtml-var tree-item-url>" target="MainWindow"><dtml-var title></a> </dtml-tree> The problem: Having both trees "enabled" (with or without dtml-comment), expanding a node gives the error: Error Type: AttributeError Error Value: 'tuple' object has no attribute 'append' Traceback: Traceback (innermost last): File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: NaviBar) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: endusermisc) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 227, in tpRender (Object: ElementWithAttributes) File /usr/src/redhat/BUILD/Zope-2.0.0-src/lib/python/TreeDisplay/TreeTag.py, line 543, in apply_diff (Info: ([None, (['AAAAAAAAAXQ=', []],)], ['AAAAAAAAAh4='])) AttributeError: (see above) Can't I have two trees in one document?

more zope promotion in Melbourne, Australia tonight.
by Anthony Baxter 25 Oct '99

25 Oct '99

<shameless self-promotion> I'm going to be on radio RRR tonight (102.7FM) sometime between 7.20 or so and 8pm, chatting about Zope, and other bits and pieces. They have a computer and internet show, Byte Into It, and I'm one of the guests. I don't think RRR do web broadcasts, but the show has a webpage of sorts at http://www.rrr.org.au/program/byteIntoIt.html </shameless self-promotion> -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

Thanks! It works. I don't yet understand how, but > it works. When ZPublisher receives an HTTP request, it builds the REQUEST variable from the request header. In the case of POSTs, in addition the header the request also contains a body. When using the multipart/form-data encoding type, this body follows a standard MIME format, wherein each piece of named data is bundled in a "multipart" attachment. Uploaded "files" have a content type, file name and binary contents, usually base64-encoded. For each such attachment, ZPublisher creates a FileObject instance (see lib/Python/ZPublisher/HTTPRequest.py). This FileObject has a filename attribute, a headers dictionary attribute, and a file attribute. The file attribute behaves like a standard Python file, and contains methods such as tell(), seek(), read() and so forth. Given such a variable MyFile, the Python expression (MyFile.file.seek(0, 2) or MyFile.file.tell()) > 0 will yield the value 1 if tell() returns > 0. The seek() doesn't return anything, so it will evaluate to None. This is handy shortcut in the Python language to make verbose tests more compact. It does not enhance readability, but reduces typing and in the context of Zope, faster than doing each operation separately. Anyway, a simpler test is checking the file name. Just testing whether the filename attribute is empty should do it.

Can't put ZClass inside itself
by Itamar Shtull-Trauring 25 Oct '99

25 Oct '99

I have a ObjectManager ZClass FooFolder, which is contained in another ObjectManager BarFolder. Product -> BarFolder ZClass -> FooFolder ZClass I cannot tell FooFolder to allow me to put another FooFolder into itself - I can tell FooFOlder to contain BarFolder, or any other object I can tell BarFolder to contain BarFolder, or any other object but FooFolders just don't show up in the list in Subobjects tab of FooFolder! The only reason I can think of is that FooFolder ZCLass is contained in another ZClass, but I can't think of a solution. -- Itamar - itamars(a)ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust?

dtml-with semantics
by John Goerzen 25 Oct '99

25 Oct '99

Hi, I have a situation like this. I am in a subdirectory ("subfolder" I guess) a few levels deep. I want to call a DTML method in /Boxes (that is, from the top). So, I first think, hmm, <dtml-var /Boxes/MyMethod>. No dice. Then I try: <dtml-with Boxes> <dtml-var MyMethod> </dtml-with> However, this dtml-with overrides some things from my document -- most importantly, id in this case. How can I solve this problem?

RE: [Zope] (possible) Answer to: What to do if manage_addImage up loads are corrupted?

[snip] > You wouldn't know how to test if a REQUEST.image1 exists or not before > actually using manage_addImage or manage_upload on that image? Test on the content type of the file object, or check whether the file object's file attribute contains a non-zero file (eg., call seek(0, 2) and then check if tell() returns > 0). The following code illustrates the latter: <dtml-if "REQUEST.has_key('MyFile')"> <dtml-if "(MyFile.file.seek(0, 2) or MyFile.file.tell()) > 0">  </dtml-if> </dtml-if> > Best regards, > Samu Mielonen Hope this helps, -- Alexander Staubo http://www.mop.no/~alex/ The difference between theory and practice is that, in theory, there is no difference between theory and practice.

aq_acquire?
by Benno Rice 25 Oct '99

25 Oct '99

What does an object need to inherit to make aq_acquire work? I've got an object that inherits from Acquisition.Implicit, but whenever something tries to call aq_acquire on it, it cops an AttributeError. Does it need to inherit from Acquisition.Explicit? Why would something be calling this if it's not there automagically? -- Benno Rice "No, no.
