guarded_getattr attribute error with complex Python structures
by Pierre-Julien Grizel 03 Aug '01

03 Aug '01

Hi, I've got a complex Zope problem... I have a resonably deep imbrication of Python scripts & DTML Methods. It happends that I finally do something like this : MyScript: return MyMethod(LIST, RECORD_SET) MyMethod: <dtml-in LIST> xxx </dtml-in> As you can guess, LIST is a... list (actually a list of tuples built from another Py script). When I try the URL, I eventually got the following traceback : Traceback (most recent call last): File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Try.py", line 221, in render_try_except result = render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Util.py", line 230, in eval return eval(code, d) File "", line 2, in f File "/isp/zope/smartway/lib/python/AccessControl/DTML.py", line 104, in guarded_getitem return guarded_getitem(ob, index) File "/isp/zope/smartway/lib/python/AccessControl/ZopeGuards.py", line 151, in guarded_getitem v = object[index] File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_With.py", line 148, in render try: return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Return.py", line 104, in render val = md[name] File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_With.py", line 148, in render try: return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_In.py", line 770, in renderwob try: append(render(section, md)) File "/isp/zope/smartway/lib/python/OFS/DTMLDocument.py", line 192, in __call__ r=apply(HTML.__call__, (self, bself, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Let.py", line 148, in render return render_blocks(self.section, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_Util.py", line 230, in eval return eval(code, d) File "", line 2, in f File "/isp/zope/smartway/lib/python/Shared/DC/Scripts/Bindings.py", line 324, in __call__ return self._bindAndExec(args, kw, None) File "/isp/zope/smartway/lib/python/Shared/DC/Scripts/Bindings.py", line 354, in _bindAndExec return self._exec(bound_data, args, kw) File "/isp/zope/smartway/lib/python/Products/PythonScripts/PythonScript.py", line 363, in _exec result = apply(f, args, kw) File "Script (Python)", line 1, in html_results_list File "/isp/zope/smartway/lib/python/OFS/DTMLMethod.py", line 187, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_String.py", line 544, in __call__ try: result = render_blocks(self._v_blocks, md) File "/isp/zope/smartway/lib/python/DocumentTemplate/DT_In.py", line 768, in renderwob push(InstanceDict(client, md)) AttributeError: guarded_getattr This happens in fact quite every time I'm handling complex Python data structures and passing them through scripts and/or methods...

Hi, I'm creating a few DTML Documents from a python script. For example: id='something' title='something' context.manage_addDTMLDocument(id,title) doc = getattr(context,id) I have a Ram Cache Manager in the root that I'd like to associate this new document with. How do I do that from python? thanks much -Kevin __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!

Internationalization

Hi people! Does anybody know a decent way to render non-english-characters (i.e. ¿,¡,á,Á,é,É,í,Í,ó,Ó,ú,Ú,ñ,Ñ, etc.) using html entities format (á Á é and so on)?. This is what I'm trying to do: accented_value(:text)= "Hél o' wórld. ¿bláh?, ¡bláh!." <dtml-var "REQUEST[accented_value]" html_quote_it_please> html_quote does not perform tyhis job.

Getting counts from a ZCatalog - it must be easier than my feeble attempt!
by S.Wilson 03 Aug '01

03 Aug '01

Hi all, I need to find out how many results would be returned from a search, without necessarily getting the results set itself. Currently the only way I can do this is to iterate through a zcatalog using <dtml-in> and add up the number of items. <dtml-var> does not support functions such as len(), but I'm convinced I'm missing something, and there is a considerably more elegant solution to this one... Here's my code: 1: Subjects 2: <dtml-in expr="('SubjectContext'),('AudienceContext')"> 3: <dtml-let sIndex=sequence-key> 4: <dtml-in expr="articleIndex.uniqueValuesFor(sIndex)" > 5: <dtml-call "REQUEST.set('nItemCount',0)"> 6: <dtml-in expr="articleIndex({sIndex:_.getitem('sequence-item')})"> 7: <dtml-call "REQUEST.set('nItemCount',nItemCount+1)"> 8: </dtml-in> 9: <a href="/index_html?<dtml-var sIndex>=<dtml-var sequence-item>"> 10: <dtml-var sequence-item capitalize> 11: </a> 12: (<dtml-var nItemCount>) 13: </dtml-in> 14: </dtml-let> 15: </dtml-in> 16: which outputs a side menu bar looking something along these lines: Subjects: Assessment (2) Content (3) Metadata (5) For Developers (5) For Educators (3) For Members (2) What I'm looking for is something like: <dtml-var expr="len(articleIndex({'SubjectContext':_.getitem('sequence-item')})[0])"> to replace lines 5,6,7. Unfortunately this gives me an error. Any ideas? Thanks, Scott Zope Newbie

OK, that´s a good tip. But still I want to use entities. Any ideas?

Trivial DTML question
by Dan Jacobs 03 Aug '01

03 Aug '01

In a folder, I have a set of DTML Methods and an ordered "lines" property that contains the names of the Methods I want to call. So in my DTML Document I have: <dtml-in items_order> <dtml-var expr="_.getitem('sequence-item')"> </dtml-in> This produces the names of the Methods. But I want the outputs of the Methods. If I try <dtml-var expr="_getitem(_.getitem('sequence-item'))"> then that gives me the HTML-quoted bodies of the Methods rather than their HTML output. How do I call the Methods instead of merely reading them? -- Yoz, on Dan's computer

ZCatalog Search Interface Broken (help?)
by Gary Perez 03 Aug '01

03 Aug '01

Hi, all. First, the versions: Linux, Zope 2.3.0, python 1.5.2 A while back, I set up a couple of Catalog-aware ZClasses that auto-update to a Catalog in Zope's root folder. In that same folder, I added the standard "Z Search Interface". Somemtime within the last couple of months, the search interface stopped working; searching on any of the indexed properties of either ZClass returns no results whatsoever. Here are the things I checked in various combinations, multiple times: - Create new ZClass(es): they still auto-update in the Catalog, search fails - Update the Catalog: looks good, search fails - Verify the Indexes of the Catalog, redo "Find Objects": works fine, search fails - Trash original "Search_Form" and "Search_Report" DTML Methods, add new from management interface: use Zope defaults, search fails During the last month or so, I removed one property from one of the ZClasses, and added a different one... neither of which were ever (nor will ever be) indexed by the Catalog or searched for via the interface. Has anyone run into a similar problem (and, hopefully found a solution)? Thanks in advance for your zen & guidance. -Gary

Temperamental Zope+Windows
by Tim Fouracre 03 Aug '01

03 Aug '01

Whenever I am using Zope (Version 2.3.3) and Windows 98 crashes/locks up (so quite freqently) and I hit ctrl-alt-del, I always have to run scandisc when the computer restarts. If i don't, Zope will not work. Normally I would just cancel the laborious scandisc process, and everything would be fine. But Zope is always adversely affected by the crash/lock up and needs sectors that contain some of its files to be repaired. I was just wondering why? as this doesn't happen with any other programs I use.

RE: [Zope] CoreSessionTracking broken under 2.4.0?
by Schmidt, Allen J. 03 Aug '01

We are at a point where we will be needing session capabilities. HAve been hearing about CST for a long time but never took the plunge. We are on the Windows platform. How hard is it to implement for us? Have not done much investigating but thought I would pop the question out there for opinions.
