Custom tpValues for dtml-tree
by Randall Kern 01 Dec '00

01 Dec '00

I'm trying to write a method that works with dtml-tree. It works great, until I try to expand a node :( Here's what I've got: class Foo: __allow_access_to_unprotected_subobjects = 1 def __init__(self, item): self.title = item.title self.items = item.items def tpValues(self): "tpValues" r = [] for item in self.items: foo = Foo(item) r.append(foo) return r class Module(Folder, etc, etc, etc,): def tree(self): "used to create a dtml-tree" r = [] for item in self.items: foo = Foo(item) r.append(foo) class Bar: __allow_access_to_unprotected_subobjects = 1 def tpValues(self): "tpValues" return self.r b = Bar() b.r = r return b Then from a dtml method inside an instance of Module I have: <dtml-tree tree> <dtml-var title> </dtml-tree> This works fine for the first page, but once I try to expand an item I get: Error Type: AttributeError Error Value: 'tuple' object has no attribute 'append' Traceback (innermost last): File /usr/src/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/src/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/src/Zope-2.2.2-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/src/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/src/Zope-2.2.2-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: randy2) File /usr/src/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: randy2) File /usr/src/Zope-2.2.2-src/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: randy2) File /usr/src/Zope-2.2.2-src/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: randy2) File /usr/src/Zope-2.2.2-src/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: forums(orderby='dir')) File /usr/src/Zope-2.2.2-src/lib/python/TreeDisplay/TreeTag.py, line 237, in tpRender File /usr/src/Zope-2.2.2-src/lib/python/TreeDisplay/TreeTag.py, line 566, in apply_diff (Info: ([None, ([140975456, []],)], [140974880, 140974088])) AttributeError: (see above) I must be missing something simple here... But I haven't been able to find it. Thanks for you help, -Randy P.S. this is the second time I've tried to become a Zope convert, and thanks to a lot of help from this list I think I might make it this time.

Why GUF or Loginmanager??
by brocken22＠gmx.de 01 Dec '00

01 Dec '00

Hallo, I'got a fundamental question: Why should you switch from the built-in authentication mechanism to a product like GUF or Login-manager?? Except of the different login interface, I dosn't see any advantage?? Please correct me. What I'm looking for is a product that redirects the authenticated-user to the part of the website where he has got his "home-folder" and also nice wolud be a search-function which gives an administrator a list of all the users with all the roles in the system. -- Sent through GMX FreeMail - http://www.gmx.net

Strange changes seen after migrating site from 2.1.6 to 2.2.4
by Chris Beaumont 01 Dec '00

01 Dec '00

Dear Zopatistas, I'm in the process of migrating a draft site to a production site.. The draft site was running 2.1.6 and the production site is running 2.2.4. I'm noticing some strange things that I can't explain.. Maybe somebody can fill me in on what's going on.. 1.) There are some changes in the way times are being handled, is there any place to read about them in detail? 2.) One form action that points at a DTMLMethod is inexplicably coming up with a "NotFound" error as if the targeted page isn't there. I tried to change the action of the form to point at another DTML Method that only contained the one line <dtml-var REQUEST> in order to debug it. This worked for one try but then going back to the page a minute later, it seems as if the change suddenly vanished..the page had suddenly gone back to pointing to the original page, which was there, but was not being found.. ( I don't think I'm seeing things.. something strange is going on. Is this situation indicative of something I should know about? File system corruption? Wierd mojo? I've never seen anything like it before..) 3.) I am having "Authorization Failed, Retry" errors where my browser won't take the correct password. It just keeps saying I'm entering the wrong one when I know I'm not. This only happens with some documents. But their security settings are the same as all of the others..ones that don't have this problem... Very strange. Thanks in advance.. Chris Beaumont cbeaumon(a)msri.org

Hi I have modified ZDGChart to display multiple columns of data returned from a ZSQL query. However I have not been able to find a way to display a legend which describes what data each line on the graph represents. Can anyone tell me how to display a legend. Thanks Austin

As luck would have it, the file did not import into Products (File /usr/local/Zope/lib/python/OFS/CopySupport.py, line 406, in _verifyObjectPaste) It DID import into the root folder (I did this purely by accident!) I was then able to recreate the called-for classes and IT WORKED!! I haven't figured out HOW yet but I will. Thanks a lot for the help, and let me know if you need any fancy Python methods...

Intercepting NotFoundError with standard_error_message
by Philipp Auersperg 01 Dec '00

01 Dec '00

I need to intercept NotFoundErrors, but am banging my head against a problem Normally this can be done by changing the standard_error_message, but there I have some questions: considering a minimal standard_error_message: -------------------------------------------------- <dtml-var standard_html_header> Error! <dtml-var standard_html_footer> -------------------------------------------------- When I provoke an error by referencing a non-existent resource the message 'Error!' gets displayed, but there is also a traceback which I cannot suppress, it always gets displayed as a HTML comment ------------------------ and now my questions 0: How can I suppress this traceback totally, my main goal Even on zope.org whe NotFoundError returns such a hidden traceback :( 1: when I remove the standard_header and footer from my standard_error_message I would expect that just the word 'Error' gets displayed, But no way, then I get a detailed Zope Error message with a traceback. How can I archive that I just get the word 'Error!' or something similar as a result. I need that desperately because such an exception is unusable when calling methods via XMLRPC, there I need a simple clear error code and not a long traceback message. 2: what makes me most happy would be returning a single XMLRPC marshallable value by dtml-return: ---------------------------------------------------- <dtml-return someErrorExpression> ---------------------------------------------------- I already have such a standard_error_message but it just works for user-generated exception, but not for the #@%&§$ NotFoundError I cannot believe that it is not possible to do error handling of NotFoundErrors but I've not found any information on that. Thanks in advance phil

Hi, Just to try , by using import/export i ported the product to another windows 98 machine.I am able to open the whole folder in the ported machine. The problem is i am not able to add a new record there using the existing script.If write new script to add record to the same table it works . so why it this happens like this ?. Do we need to import any other files?.When i add a record using existing scripts it asks for username & password. when i type it , it doesn't take. Thanks, jacintha

Is it possible to build a folder zclass with user folder built in?
by Dirksen 01 Dec '00

01 Dec '00

I built a user folder with LoginManager, tested it on normal folder. Then I tried to build a folder zclass containing the tested LM user folder, hoping that, when I instantiate this zclass, I have a folder ready for customized authentication. I tried this on objectmanager baseclass and ofs:folder baseclass, neither worked the way I anticipated, just weird behaviors. It seems to me the user folder works inside the zclass folder (under the product tree) rather than in its instance. Any hint please?
