I have also tried comparing _.str(my_title) and _.str(get_page_title) just to make sure I was comparing strings. But the if clause always evaluates true. Any ideas? Maybe, "get_page_title" is callable. In this case, e.g., "dtml-get_page_title;" is very different from "get_page_title". Try to replace "get_page_title" by "_['get_page_title']" at both places in your code.

Can Zope use a Different Python?
by Gary Perez 11 Nov '00

11 Nov '00

Hi. We've got Zope 2.2.2 installed on a Linux box. We want to be able to use the full-up python that's on the box instead of the python interpreter that comes with Zope for playing with External Methods. Is there any way to circumvent Zope's python in this way? If not, what's the easiest way to extend Zope to be able to use our non-Zope python? Alternatively, we're plagued by import and attribute errors when accessing the External Methods. Will simply moving (or linking?) all the pieces (whatever.py, __init__.py, etc.) into a subdirectory of "Shared" fix the problem? Thanks in advance for your help. -GMP

Re: [Zope] How do I set the Title property of a File object from a DTML method
by magnus＠websys.no 11 Nov '00

11 Nov '00

[me] | But I'm unable to set the Title property of a File object. [Erik] | Is it just the title property? All the others you can fiddle around | with? Try manage_changeProperties() instead. I know (from | lib/python/OFS/Image.py) that the File object has its own | manage_edit() method, you could try that one. Actually it turned out to be a different problem (I work around it now). My form looked something like this: <form action="&dtml-absolute_url;" method="POST" enctype="multipart/form-data"> <input type="hidden" name="id" value="<dtml-var id>"> <input type="text" name="title:text" value="<dtml-var title>"> <input name="change:method" type="submit" value="Change"> </form> and the change method something like this: <dtml-call "manage_editProperties( REQUEST )"> <dtml-call "RESPONSE.redirect('index_html')"> Both the form and the change method would be DTML methods in my containing ZClass object. For my own ZClass subobjects, this worked fine, but for a File subobject it would just show the File instead of running the change method. In the end I had to make the action field in the form tag above include "/change" if the object was a File. Could someone explain this to me? -Magnus

bookmark importer
by Philipp Dunkel 11 Nov '00

Hello guys I' have here a pyton file that allows you to import your bookmarks from IE. The following prob is that it works on windows98 zope 2.2.2 and not on a unix system. The file temp.txt stays empty and you get the message 'unable to export favourites' anyone any idea? def GetBookmark(self): import string if self.REQUEST['HTTP_USER_AGENT']=='PostFavorites': print self.REQUEST.cookies file = self.REQUEST.stdin if file: file.seek(0) LBook=[] while 1: line = file.readline() if not line: break LBook.append(line) RBookmarkList=RList(LBook[RFirst(LBook):len(LBook)]) print RBookmarkList ftemp = open('temp.txt','w') ftemp.write(RBookmarkList) ftemp.close() return 'RBookmarkList' else: s='<A HREF=''javascript:window.external.ImportExportFavorites(false,' s=s+'"http://aegis:8080/Bookmarker");' s=s+'window.location.reload();>Click me...</A><P>' ftemp = open('temp.txt','r') if ftemp: l=ftemp.readline() ftemp.close() ftemp = open('temp.txt','w') ftemp.close() if l: s=s+l return s def RFirst(l): import string for i in range(len(l)): if (string.find(l[i],"<DL>")>-1): return i return None def RLast(l): import string k=0 for i in range(len(l)): if string.find(l[i],"<DL>")>-1: k=k+1 if string.find(l[i],"</DL>")>-1: k=k-1 if k==0: return i def RList(LD): import string Dict='' LDict='' iLast=0 for i in range(len(LD)): if i>=iLast : l=LD[i] if (string.find(l,"<DT><A HREF")>-1): s=l[string.find(l,"<A HREF")+9:len(l)] s0=s[0:string.find(s,'"')] s=s[string.find(s,">")+1:len(s)] s=s[0:string.find(s,"<")] Dict='{title:"'+s+'", url:"'+s0+'"}' if LDict=="": LDict=Dict else: LDict=LDict+','+Dict if (string.find(l,"<DT>")>-1) and (string.find(l,"<A HREF")==-1): s=l[string.find(l,"<DT>")+4:len(l)] s=s[string.find(s,">")+1:len(s)] s=s[0:string.find(s,"<")] iFirst=i+1 iLast=RLast(LD[iFirst:len(LD)])+iFirst LDNew=RList(LD[iFirst:iLast]) Dict='{'+s+':['+LDNew+']}' if LDict=="": LDict=Dict else: LDict=LDict+','+Dict return LDict TIA Rishi

Re: [Zope] logging for virtual hosts
by zope＠concision.com 11 Nov '00

11 Nov '00

Well, I tried the source hacking approach and seem to have found success with relatively little pain. In ZServer/medusa/http_server.py, the "log" method of the class "http_request" can be modified to report the request hostname which is readily available via the get_header method in the same class. Here is my modified "log" method: def log (self, bytes): user_agent=self.get_header('user-agent') if not user_agent: user_agent='' referer=self.get_header('referer') host=self.get_header('host') if not referer: referer='' self.channel.server.logger.log ( self.channel.addr[0], ' - - [%s] "%s" %d %d "%s" "%s" %s\n' % ( self.log_date_string (time.time()), self.request, self.reply_code, bytes, referer, user_agent, host ) ) Note that this puts the request hostname at the end of the log entry.

ZClass
by kosh 11 Nov '00

11 Nov '00

>From inside what object should I inherit from to get a history option for a zclass or what method would I need to write. I have looked at lots of examples of zclasses and so far none of them have a history tab. I am working with the STX_Document type and made a new zclass based on that which includes renderable and catalogaware as base classes. Those were the instructions on the STX document page but that still did not give me the option for a history tab but it did fix other things that I needed. Thanks Kosh

ZClasses & inheriting property(sheets) : yes/no?
by Aaron Straup Cope 10 Nov '00

10 Nov '00

Hi, If I create a ZClass that inherits another ZClass, do I also inherit the latter's properties/propertysheet? From what I've read so far, I thought the answer was yes but I can't seem to figure out how to *get* at them. I created a ZClass called "Foo" that inherits a ZClass named "Meta". Meta had two properties : author and title but neither appear to be set when I create a new Foo object. I banged out something in plain-old Python (see below) since I was pretty sure this was the kind of thing Python was so good for (I am normally a Perl weenie....shhhhh :-) and everything worked fine. I've been looking around the docs and the how-to's but nothing seems to discuss the idea of inheriting properties (?) across ZClasses. Is it possible? Thanks, class Meta: def __init__(self,title,author,timestamp,keywords,body,public,display): self.title = title self.author = author self.timestamp = timestamp self.keywords = keywords self.body = body self.display = display self.public = public **** from Meta import Meta class Library(Meta): def __init__(self,title,author,timestamp,keywords,body,public,display,foo,bar=""): Meta.__init__(self,title,author,timestamp,keywords,body,public,display) self.foo = foo self.bar = bar **** from Meta import Meta class LibraryClass(Meta): def __init__(self,title,author,timestamp,keywords,body,public,display): Meta.__init__(self,title,author,timestamp,keywords,body,public,display) *** # from yadda yadda import ... lib = Library("budwork","bud","now",["foo","bar"],"bobdy",1,0,"foopybird") libclass = LibraryClass("classwork","bud","now",["foo","bar"],"bobdy",1,0) print "Class Title is " + lib.title print "LibClass Title is " + libclass.title
