Storing sensitive data
by Dan Gaibel 13 Dec '06

13 Dec '06

Hi all, I am wondering about storing credit card and personal information in Zope 2.8.6 (with Python 2.3.5.) Is there a simple way to secure data with SSL/https without having to run Apache? I found ZServerSSL and I wonder if that will be the answer. Has anyone used the product with Zope 2.8? I am a newbie with an SSL certificate and I frankly don't know what to do with it. Thanks in advance for any help! Best, Dan

Zeo question
by ian 13 Dec '06

13 Dec '06

Hi, Hope you can help 1. I am having trouble connecting a zope client to a zeo database.The server and client are in different goegraphical locations and behind different proxies and firewalls. I read that they communicate using a 'custom RPC protocol'...what does this mean and does it have any influence on which firewall/proxy rules we need to implement on our network?? 2. I can create a custom skin on each zope (in reality plone) instance right or is each zope instance is just a mirror of the other? thx -- Ian Lawrence http://ianlawrence.info Centre for Bioinformatics INSTITUTO NACIONAL DE PESQUISAS DA AMAZÔNIA-INPA RUA ANDRÉ ARAÚJO N º .2936 , BAIRRO DO ALEIXO MANAUS-AMAZONAS-BRAZIL Research Program in Biodiversity http://ppbio.inpa.gov.br PHONE: 055-92-3643-3358 CEP. 69011 -970 | Please do not send me documents in a closed | format.(*.doc,*.xls,*.ppt) | Use the open alternatives.

Get a reference to the latest transaction
by Peter Bengtsson 13 Dec '06

13 Dec '06

Is it possible? If so, how do I get a reference to the last/current transaction that just happened within a method? Pseudo code: class MyFolder(Folder): def manage_afterAdd(self): self.image_count = 0 def addImage(self, imgdata, REQUEST): self.manage_addImage('someid', file=imgdata) self.image_count = self.image_count + 1 url = self.absolute_url() + '?transactionid=%s' % get_transaction().getId() REQUEST.RESPONSE.redirect(url) If I had that, I could then do the following in my template: <div tal:condition="request/transactionid|nothing"> Image uploaded. <a tal:attributes="href string:undoTransaction?transactionid=${request/transactionid}" >Undo</a> </div> Is it possible? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Yes there is a 'return 0' at the beginning. This code always executes and works just fine, as I've mentioned before, as long as the template is in the root folder of the given Web site. I'm trying to put this template in a "root" folder that services all the Web sites of the portal, and that's where I'm having trouble.

tal conditional help
by David Bear 13 Dec '06

13 Dec '06

I have a page template that <div> tag to insert another template. currently I do <div content="structure here/form.pt"> form template </div> I rely on the form.pt object to exist in the folder where the template is called from. This works okay. However, I think it would be wise to put some kind of error checking in the tal to avoid sending some kind of exception to the browser. what I think would be the correct thing is to test if form.pt exists, if not do insert nothing, otherwise insert it as above. However I can't seem to locate any tal syntax that lets me do this. I found tal:condition but haven't found any examples of using a 'exists' type of condition. Any pointers? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

From: Jonathan <dev101@...> > targetFolder = string.join(traverse_subpath, '/') #you will have to play with this to get the right target folder for your app > aFolder = context.restrictedTraverse(targetFolder) > searchRes = aFolder.Catalog(<some search string here>) > <do something with search results here> First of all, thank you very much for your help. I'm confused. I had a programmer working for me that wrote the following code: return 0 catalog = '' try: catalog = getattr(context, context.superValues('ZCatalog')[0].id) except AttributeError: pass if catalog: return 1 Now, that works just fine if I leave the page template that calls it in the folder of a specific Web site. But when I put that template in a "root" folder that all the Web sites of the portal can call, it only gives me a printout of the tree of what's in the root folder. What I'm trying to accomplish is that it gives me the tree of the specific Web site folder from which it is called. My problem is that I frankly don't understand what my programmer wrote...how it works. Research taught me that "superValues" returns the meta_data of ZCatalog, we're popping the first element of the tuple, getting it's ID, all in context of the call, and calling that a catalog. But why do we return "1" if we get a catalog? How does that print the catalog? Then, how do I incorporate your information to achieve my goal?
