Hi, after some pretty good experiences with dav (using the cadaver client) my X server crashed (which terminated zope and two open dav clients) dav suddenly stopped working. i get the following error message: Connecting to server... connected. Locking `team.html': failed: 500 Internal Server Error with the webdav locking manager i can find no open locks. the normal web interface still works with no problems. what now? :) --Oliver

Hello there, I have an External Method which takes as a parameter the basepath of an LocalFS Object: <dtml-let imagen="Imagenes['logo.gif'].basepath" > <dtml-call "minipil(imagen)"> </dtml-let> The external Method is a s follows: #minipil.py import Image def conversion(a): im = Image.open(a) return im.format Everything is very simple but I get the following error: Error Type: IOError Error Value: [Errno 13] Permission denied: 'c:\\TestRes\\images' where this is the base path for the Local File System <!-- Traceback (innermost last): File C:\TestRes\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\TestRes\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\TestRes\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File C:\TestRes\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\TestRes\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: Prueba) File C:\TestRes\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: Prueba) File C:\TestRes\lib\python\OFS\DTMLMethod.py, line 172, in __call__ (Object: Prueba) File C:\TestRes\lib\python\DocumentTemplate\DT_String.py, line 528, in __call__ (Object: Prueba) File C:\TestRes\lib\python\DocumentTemplate\DT_Let.py, line 147, in render (Object: imagen="Imagenes['logo.gif'].basepath") File C:\TestRes\lib\python\DocumentTemplate\DT_Util.py, line 337, in eval (Object: minipil(imagen)) (Info: imagen) File <string>, line 0, in ?

RE: [Zope-Annce] [Ann] DocFinder 0.1: ask Zope about its document ation
by Jay, Dylan 12 Feb '01

Is there someway you could roll this into the help system so there is way to get to it from the management screen. Perhaps every object can have two kinds of help when you push the help button. One is the automatically generated help which you have done and then whatever additional help is provided by the product. I have yet to try this product but it is a brillent idea. Like building a autogenerated ZQR into the product itself. I'd really like to see this in a more accessable form. > -----Original Message----- > From: Dieter Maurer [mailto:dieter@handshake.de] > Sent: Tuesday, 13 February 2001 5:01 AM > To: zope(a)zope.org; zope-announce(a)zope.org; dieter(a)sz-sb.de; > deddo(a)sz-sb.de; zimmer(a)sz-sb.de; m.becker(a)sz-sb.de; markus(a)sz-sb.de > Subject: [Zope-Annce] [Ann] DocFinder 0.1: ask Zope about its > documentation > > > Recently, I have written several times: > > Look at the Zope source for documentation. > Zope has quite good source documentation. > > However, as the Zope source is huge, this advice is not so > easy to follow. > > > Therefore, I made "DocFinder".

Should I switch to Python 1.5.2?
by Kyler B. Laird 12 Feb '01

12 Feb '01

I've been using Python 2.0 with Zope 2.3.0. It generally works well, but lately I've run into problems using string.split() and now I notice that httplib encounters a similar ("loop over non-sequence") problem. I'm thinking of chucking it and going back to Python 1.5.2, but I found that it does not compile out of the box under SPARC Solaris 2.8. # ./python /usr/local/lib/python1.5/compileall.py 'import site' failed; use -v for traceback Traceback (innermost last): File "/usr/local/lib/python1.5/compileall.py", line 128, in ? sys.exit(not main()) File "/usr/local/lib/python1.5/compileall.py", line 121, in main success = compile_path() File "/usr/local/lib/python1.5/compileall.py", line 85, in compile_path if (not dir or dir == os.curdir) and skip_curdir: AttributeError: curdir (It doesn't know about os.curdir or os.getcwd().) So...before I try beating 1.5.2 into submission under Solaris, I want to know if there's an update of Zope in the near future that fixes the Python 2.0 compatibilities. Thank you. --kyler

[Ann] DocFinder 0.1: ask Zope about its documentation
by Dieter Maurer 12 Feb '01

12 Feb '01

Recently, I have written several times: Look at the Zope source for documentation. Zope has quite good source documentation. However, as the Zope source is huge, this advice is not so easy to follow. Therefore, I made "DocFinder". This small product allows you to ask any object in your Zope system about its documentation: methods, roles, arguments, documentation strings. As even simple Zope objects expose hundreds of methods, I made the display a two level interactively explorable tree structure. The first level shows you the classes, the object is build from. Expanding a class will show you the class's attributes. I think, this product can help you in various ways: as a Zope programmer: * learn about the available methods and their arguments * learn about Zope's architecture and building blocks * check for security holes as a Zope maintainer * help you to bring interfaces and implementation in line * help you to straighten out some quirks in Zope's implementation * help you to improve Zope documentation * help you to detect potential security risks due to unprotected attributes More information and download at URL:http://www.dieter.handshake.de/pyprojects/zope/DocFinder.html

Re: [Zope] Help: dtml-var expr -> DTML method -> ZSQL method
by Dieter Maurer 12 Feb '01

Martin Andrews writes: > <dtml-var expr="get_rid()"> You break the namespace chain! Called this way, "get_rid" does not have any context (if it is a DTML Method rather than a DTML Document). Any access to a Zope object will fail. Use: <dtml-var expr="get_rid(_.None,_)"> Dieter

Re: [Zope] ZClass inheritance and contained objects (Zope 2.3.0)
by Dieter Maurer 12 Feb '01

12 Feb '01

Oliver Frommel writes: > I add a DTML Method to a ZClass in the Product Manager. > Is this DTML Method now supposed to show up in the Contents tab of a ZClass > Instance? No. The method lives in the class while the ZInstance's Contents view shows the private content items of this instance. I would like that a ZInstance could override the infrastructure defined in the class (as is the case, e.g., in Python). However, ZClasses are not implemented this way. Dieter

Re: [Zope] tree structure in zope
by Dieter Maurer 12 Feb '01

jacintha menezes writes: > Kindly may i know when a tree gets expanded in zope does it rebuild > from root > (starting position) or it gets rebuild from the place it gets expanded. Usually, the hierarchy is simply there, the tree tag just displays part of it. The table representing the tree is regenerated for each request from scratch. Thus, the "branches" method (or "branches_expr") is recalled for all visible tree nodes and not only for the expanded node. Dieter

curve ball with <form>
by Gary Lowder 12 Feb '01

12 Feb '01

I've got a small form imbedded within a much larger DTML Method. While coding along I stuck it in there. Test views of the page work great. As soon as I created the DTML Method that the FORM will POST to, I get this error (now this is only on viewing the Calling Page): Error Type: TypeError Error Value: argument 1: expected read-only character buffer, ImplicitAcquirerWrapper found My form is this: <form action="del_item" method="POST"> Input reason for deletion:<input type="text" name="reason:text" size="40"> <input name="delbutton" type="submit" value="Delete Item"> </form> When the method 'del_item' doesn't exist, the page displays correctly. As soon as I create the method 'del_item', I can't view this page anymore without the above error. Am I barking up the wrong tree? What would zope care if 'del_item' existed or not, it apparently doesn't care when it is yet to exist, but when I create it, the calling page isn't viewable, and I've not even pressed the 'submit' button. Thanks for your time and effort. Gary.
