locale roles don't work with HTMLDocument procucts
by Marcus Schopen 03 Apr '02

03 Apr '02

Hi, I have problems with HTMLDocument (both products) on on Zope 2.5.0 (woody debian). Installed the HTMLDocument product (http://www.zope.org/Members/sf/HTMLDocument) After that I created a local role "lehstuhl", which has for testing purpos same rights as a manager (I just selected all). Then I created a new folder "/test" with an user "test". User "test" is set to local roles "lehrstuhl". As user "test" I created some HTMLDocuments in the /test folder using Zope's managment screen. Problem: when connecting via FTP as user test to folder "/test", it's impossible to to download these HTMLDocuments. FTP Client says "unauthorized". Upload is fine. Giving user "test" the role "Manager" everything works fine. That's strange, because role "lehstuhle" has all rights like a manager !!! I get a similar behaviour with the other HTMLDocument wrapper (http://www.zope.org/Members/unfo/howto_wrapper) Here is download o.k., but upload doesn't work. Before upgrading to Zope 2.5.0 both products worked without problems with 2.3.3. Any help is welcome !!! Thanks & bye Marcus -- ,---- [ Marcus Schopen ] | (0> | //\ P.O.

Re: Copying a Zope Site

I mean, if one copies a site > using this product will invididual objects in the newly minted copies have > the same modification dates as the originals? No, I believe it changes the modification dates. This is how it knows what is out of synch, unless I am very much mistaken. I'm less sure of the behavior of import/export, though I think it changes dates too. IMHO, if you are moving a site en-masse, I think you'd be better off to use import/export. Zsyncers value would seem to be in moving small changes from the staging site to the production site, after having made the initial deployment. I am still not happy with the mechanisms for staging a site when it is necessary to merge-back changes originating from the production site (e.g. user comments which have been added to a website). This requires some very careful thought on your part, if you have such a requirement (I still haven't figured it all out, so I would muddle the issue with any specific recommendations!). Of course, ultimately this is what ZEO is about, but it's an automatic method, so I don't think there's much opportunity to intervene in the process and copy selectively. That's what Zsyncer does. There is a hack to Zsyncer to make it reversible (I have a copy emailed from the original author -- it may not be available on the web, yet), but it's supposed to have some significant bugs with the file time handling. It does the synching manually though, so it's not like a CVS check-in, where you get the *most-recent* version from either site. That's probably what I really want, but I don't know how to set it up yet. I've been meaning to look into that, but haven't found the time. sigh. But it does exist. Ultimately ZEO + versions may be the "right" way to do this, but I haven't even begun to figure that out.

Acquisition for bilingual site
by Stephan Goeldi 03 Apr '02

03 Apr '02

Acquisition trouble I am setting up a bilingual website (english/german). I followed the instructions in http://www.zope.org/Members/Hoekstra/ChangingZopeContexts which I modified a little, because I don't have more than 2 languages on this site. I created the following structure: / navigation standard_html_header standard_html_footer index_html de/ content about/ order/ ... en/ content about/ order/ ... home/ index_html The logic is this: By entering the website, /home/index_html is called. It looks at the browser language and decides, whether it is german (->de) or anything else (->en). This is /home/index_html: ---------- /home/index_html ---------- <dtml-var standard_html_header> <dtml-if "REQUEST.HTTP_ACCEPT_LANGUAGE=='de'"> <dtml-var de> <dtml-else> <dtml-var en> </dtml-if> <dtml-var standard_html_footer> ---------------------------------------- So this should point at /en, if the browser language is different than german (language selection works perfect in this case). The content of /de are some subfolders without an index_html, so the index_html of / should be used. This is /index_html: ---------- /index_html ---------- <dtml-var standard_html_header> <dtml-var navigation> <dtml-if content> <dtml-var content> </dtml-if> <dtml-var standard_html_footer> ---------------------------------------- ---------- /navigation ---------- <a href="<dtml-var about>">about</a> | <a href="<dtml-var performance>">performance</a> | <a href="<dtml-var security>">security</a> | <a href="<dtml-var prices>">prices</a> | <a href="<dtml-var support>">support</a> | <a href="<dtml-var order>">order</a> | <a href="/en/"><dtml-var english></a> | -->icon <a href="/de/"><dtml-var deutsch></a> | -->icon ---------------------------------------- So if the browser language is detected, and points to /de or /en, /index_html should be used, to display an object called 'content' (if it exists) and the /navigation object should be included. If the user decides to select another language, he/she can click on the appropriate language link (de/en). On this level, the browser language detection should no more be active. But what I get is this traceback, which seems to originate from /navigation: Traceback (innermost last): File C:\ZOPE\lib\python\ZPublisher\Publish.py, line 150, in publish_module File C:\ZOPE\lib\python\ZPublisher\Publish.py, line 114, in publish File C:\ZOPE\lib\python\Zope\__init__.py, line 158, in zpublisher_exception_hook (Object: zopehosting) File C:\ZOPE\lib\python\ZPublisher\Publish.py, line 98, in publish File C:\ZOPE\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: index_html) File C:\ZOPE\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: index_html) File C:\ZOPE\lib\python\OFS\DTMLMethod.py, line 127, in __call__ (Object: index_html) File C:\ZOPE\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: index_html) File C:\ZOPE\lib\python\OFS\DTMLMethod.py, line 120, in __call__ (Object: standard_html_header) File C:\ZOPE\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: standard_html_header) File C:\ZOPE\lib\python\OFS\DTMLMethod.py, line 120, in __call__ (Object: navigation) File C:\ZOPE\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: navigation) KeyError: about So there seems to be a problem with the first called navigation object (about). This is a subdirectory of /de and /en.

Allowing access to Zope Product in Control Panel
by Itai Tavor 02 Apr '02

02 Apr '02

Hi, I have a python Product MyProduct, defining a class MyClass. I want to be able to do two things with this class from a Python Script: - Access a property defined in the class without creating an instance of the class class MyClass(SimpleItem): menu = ('a', 'b', 'c') In Python Script: menu = context.Control_Panel.MyProduct.MyClass.MyClass.menu - Create an instance of MyClass without doing registerClass on it. The question is, how do I create the right permissions so the above can be done? I tried playing with the various methods detailed in PythonScripts/module_access_examples.py but didn't get anywhere.

Formulator and ZDebug incompatibility
by Itai Tavor 02 Apr '02

02 Apr '02

Hi, I posted this question on the Formulator mailing list but it didn't seem to interest anyone there, so I'm posting it here in hope that anyone here has some helpful info or a workaround. It seems that Formulator is still incompatible with ZDebug. This problem was discussed briefly back in May 2001 (<http://lists.zope.org/pipermail/zope/2001-May/091103.html>), related to Formulator 0.9.1 and ZDebug 0.2. I'm using Formulator 1.2.0 and ZDebug 0.3 in Zope 2.4.4b1, and I have the same problem - an error message if a form field fails to validate - although the error message is a bit different this time: Error type: TypeError Error value: __init__() takes exactly 3 arguments (2 given) Traceback (innermost last): File /usr/local/zope/2.4.4b1/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/2.4.4b1/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2.4.4b1/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: Forms) File /usr/local/zope/2.4.4b1/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2.4.4b1/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: feedback) File /usr/local/zope/2.4.4b1/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: feedback) File /usr/local/zope/2.4.4b1/lib/python/OFS/DTMLMethod.py, line 200, in __call__ (Object: feedback) File /usr/local/zope/2.4.4b1/lib/python/DocumentTemplate/DT_String.py, line 546, in __call__ (Object: feedback) File /.../Zope/Products/ZDebug/DTMLDebug.py, line 305, in debug_render_blocks File /.../Zope/Products/ZDebug/DTMLDebug.py, line 237, in debugException File /.../Zope/Products/ZDebug/DTMLDebug.py, line 303, in debug_render_blocks File /usr/local/zope/2.4.4b1/lib/python/DocumentTemplate/DT_Try.py, line 212, in render File /usr/local/zope/2.4.4b1/lib/python/DocumentTemplate/DT_Try.py, line 221, in render_try_except File /.../Zope/Products/ZDebug/DTMLDebug.py, line 287, in debug_render_blocks File /.../Zope/Products/ZDebug/DTMLDebug.py, line 237, in debugException File /.../Zope/Products/ZDebug/DTMLDebug.py, line 182, in debugWithNamespace TypeError: (see above) Anybody else seeing this?

IIS, PCGI, authentication
by Tom Nixon 02 Apr '02

02 Apr '02

I am running Zope under IIS using PCGI and it works great, but I can't view pages that require authentication. I found the following in the archive but it caused a forbidden error rather than popping up the login dialog. Does anyone know what the easiest way to do this is? T. Note that you probably have to tweak your IIS configuration to get IIS to pass authentication headers to Zope. You need to make sure that BOTH "Windows NT Challenge/Response" AND "Basic Authentication" are DESELECTED for the cgi directory where you placed the cgi exe. Otherwise, IIS will intervene on every request and try to do the authentication itself (which will fail, of course).

List editing with page templates
by Richard Wesley 01 Apr '02

01 Apr '02

I need to create a form (using page templates) that does roughly this: <BasicData> <selectable list of homogenous objects to attach to BasicData> <list of homogenous objects already attached to BasicData> The problem is that I can't seem to make the attached list persistent. In my action script for attaching a new list object, I check the request to see if the list is present and append the selected object to the attached object list, but the script never seems to have access to the request passed to the form. Slightly simpler test script (trying to accumulate two form variables): names=[] if request.has_key('names'): names=request.get('names') names.append ({'name':name,'age':age}) request.set('names',names) return container.form() What am I missing?

re: error message importing zope file
by Mark Halegua 01 Apr '02

01 Apr '02

I was away on a trip and using my laptop to work on a project. (by the way, traveling on Amtrak was great: they have a couple of seats in each car near an electric outlet and I was able to work for hours, with no distractions - i.e., no telephone, no pager, no tv - and got a lot of work done learning Zope.) I created a few pages of a site for a client, and tried to export it from the laptop to my desktop system for eventual transfer to the client's web server. However, the import isn't working. I know I have the file in the import directory on my office server (running SuSE 7.0, Zope version 2.4.1) and using a workstation with SuSE 7.2 to connect throught the Konquerer browser. The laptop is running SuSE 7.3 with Zope version 2.4.0. The error message I keep getting when I try to import the file through the Zope interface is: Error Type: UnpicklingError Error Value: invalid load key, 'ö'. I don't want to redo the work, so can anyone tell me why the import isn't working? Thanks, Mark
