reinstall

Hi, I am running FreeBsd and I did a make install to upgrade my zope from 2.2 to 2.3. My validation is done by apache using the <directory> directive of the cgi- bin directory but it does not seem to work. I keep getting the error below. Can anyone give me any ideas on how to set it up again probably from scratch? Thanx. Zope Error Zope has encountered an error while publishing this resource.

FW: Reading properties from nested objects.
by Michael Van Cleave 25 Feb '01

25 Feb '01

I have am using something similar to the Yihaw Pointer in the Yihaw class to reference objects elsewhere in the folder structure of my site. The pointer has a property on it that stores the absolute url of an object that it is referencing. I cannot figure out how to use the stored absolute url to read elements off the remote object. >From an arbitrary dtml-method, how can I render a variable property on a remote object. For example in the following site structure /root /x index_html pointer_method (has a property "url" which is "/y/objectZ") /y objectZ The index_html file calls pointer_method and reads the property "url", creating a link to the object that "url" points to (objectZ). This works great. However, I would like to read properties off that remote item (say the title for example) and render them in the index_html file. I have tried this, but it generates a key error: <dtml-call "REQUEST.set('location', _.string.replace(pointer, '/', '.'))"> <dtml-var location.id> If I hard code it as such: <dtml-with y> <dtml-with objectZ> <dtml-var title> </dtml-with> </dtml-with> I can read the title, but I cannot figure out how to convert the absolute url into a with statement or a var. Any help is greatly appreciated. -m

Re: [Zope] sidebar sorting

In your example, it would use the attribute with the literal name "_.[sort]". But you want "_.[sort]" evaluated and use the result as sort specification. You can do that with "sort_expr" (rather than "sort"). Dieter

"in"'s sort does not support this. You can do it in an external method using Python's "sort" method or extend "in"'s sorting capabilities. > (2) i have a dtml-tree, but i don't want to list the contents of the current > folder but of PARENTS[1]. <dtml-tree "PARENTS[1]"> Dieter

RPM, python scripts, threads
by Philippe 24 Feb '01

24 Feb '01

I've got zope 2.3.0 running with python 1.5.2 on RedHat 6.2. I'm afraid the threads for python have not been compiled in. Is there an RPM that does it? (My system administrator will not let me install anything without an RPM. How difficult is it to write an RPM?) thanks a lot, -Philippe (Below, I'm including the page source of an error message trying the Guest_Book example of the Zope Book, which btw is an excellent book :-) <!-- Traceback (innermost last): File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 187, in publish File /usr/share/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 171, in publish File /usr/lib/python1.5/site-packages/ZPublisher/mapply.py, line 160, in mapply (Object: addEntryAction) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 112, in call_object (Object: addEntryAction) File /usr/share/zope/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: addEntryAction) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: addEntryAction) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_Util.py, line 334, in eval (Object: addEntry(guest_name, comments)) (Info: guest_name) File <string>, line 0, in ?

Xron question--why won't method work
by Chris Muldrow 24 Feb '01

24 Feb '01

Here's a clarified version of a question i asked earlier that is still stumping me. Why will this method work as a regular DTML Method but not as a Xron method: <dtml-in expr="objectValues('DTML Document')"> <dtml-let newname="'o13'"> <dtml-let nameadd=id> <dtml-let newname="nameadd+newname"> <dtml-let newtitle="'Chris'"> <dtml-let story=document_src> <dtml-let credate="ZopeTime()"> <dtml-with "PARENTS[0]"> <dtml-call expr="addFLSNews(newname, story, credate)"> </dtml-with> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-let> </dtml-in> And here's the external method that it's calling: def addFLSNews(self, newid, data, REQUEST=None): """ """ # Get the actual destination object, using the this() # method, to be sure we get it in the right context.. self=self.this() # Create the new instance newob=self.Control_Panel.Products.FLSNewsStory.FLSNewsStory(data) newob._setId(newid) self._setObject(newid, newob) newob.title=getTitle(data) varStoryName=getStoryName(data) varUser=getUser(data) varPicID=getPicID(data) varCategory=getCategory(data) varLocality=getLocality(data) varBasket=getBasket(data) varNwords=getNwords(data) varEditionInfo=getEditionInfo(data) varSummary=getSummary(data) self._setProperty('User', varUser, type='string') self._setProperty('StoryName', varStoryName, type='string') self._setProperty('PicID', varPicID, type='string') self._setProperty('Category', varCategory, type='string') self._setProperty('Locality', varLocality, type='string') self._setProperty('Basket', varBasket, type='string') self._setProperty('Nwords', varNwords, type='string') self._setProperty('EditionInfo', varEditionInfo, type='string') self._setProperty('Summary', varSummary, type='string') It's hitting a problem at the self.setObject line. This method works when I run it as a regular DTML Document, but it hits an "Attribute Error on self.setObject when I run it as an Xron. I'm using the trigger tab, but I've also tried letting it run as scheduled--neither works.

LocalFS
by Paul Zwarts 24 Feb '01

24 Feb '01

Hi, How do I store a file in LocalFS? Of about 8 emails I've posted for various questions in the last 4 months, 1 was answered. The rest ignored. Seemingly you get a response if you pretend to be stupid and ask for the whole answer without denoting that you actually have done some research or supply contraindications to your problem.... Cheers and excuse today's hangover moodiness, Paz

ZCatalog OR search problems
by Oliver Frommel 24 Feb '01

24 Feb '01

Hi, I've implemented an OR search for ZCatalog following the HowTos and mailing list postings. However I am still trying to solve the problem that a search result shows up twice when it matches two subsearch criteria. I tried a Python Method "uniq" to make the results of the search unique, but get an error "Error Type: AttributeError Error Value: __hash__". dtml: <dtml-let resa="Catalog(text_obj=begriff)" resb="Catalog(abstract_obj=begriff)" resc="Catalog(title=begriff)" res="resa[:_.len(resa)] + resb[:_.len(resb)] + resc[:_.len(resc)]"> <dtml-in "uniq(items=res)" size=50 start=query_start> ... python method (parameter "items"): d = {} for item in items: d.update( { item: 1 } ) return d.keys() stack trace: ... File /opt2/cvs/Zope2/lib/python/Products/PythonScripts/PythonScript.py, line 337, in _exec (Object: uniq) (Info: ({'script': <PythonScript instance at 8c73b88>, 'context': <Folder instance at 8c95b88>, 'container': <Folder instance at 8968e08>, 'traverse_subpath': []}, (), {'items': [<mybrains instance at 8b215d0>, <mybrains instance at 8c2e778>, ..... File Script (Python), line 5, in uniq .. why can't I iterate over the "items" search results as a normal list? Is there any way to make this work? thanks for your help --Oliver
