Use of Zope
by Jim Kutter 07 Aug '02

07 Aug '02

I was curious to see what everyone is using zope for. I would love to take a quick survey and see who is using Zope and why? I'll start it off. I'm using Zope for my company's website, and I chose it beause it was the cheapest solution, and it did everything we needed (templates, mysql integration, remote management, and fantastic code re-use possibilities) -jim

Zope context
by Bo M. Maryniuck 07 Aug '02

07 Aug '02

Hello, all. Somebody know how to get a Zope Context within Zope Product or External Method? For example, I have an object (e.g. DTML Method) somewhere in Zope, called as "MyObject". It's might be accessed: http://www.myhost.com/test/MyObject The problem is, that External Method like this works O.K.: [test.py (External Method)] --------8<---------- def foo(self): return self.test.MyObject() --------8<---------- ...but *within a class* -- not: [test.py (External Method)] --------8<---------- class bar: def spam(self): return self.test.MyObject() def foo(self): b = bar() return b.spam() --------8<---------- ...because I need a context, like: return context.test.MyObject() ...but I still can't find how to get it. ;-( Thank you much. -- Sincerely yours, Bogdan M.

LDAPUserFolder Problems
by Philip Jackson 07 Aug '02

07 Aug '02

Dear All, This is my first posting so if I have the wrong list please point me in the correct direction! We have installed the LDAPUserfolder Product in Zope and after much trial and error got it to work. We want to be able to produce a login page that authenticates to our directory and then depending on the user name re-directs the user to their own set of web page content, a bit like a portal. Our dtml scripting is basic so we are just using what we can find and experimenting with that. We are curious as to how we can achieve this. We have used the experimental login.dtml that came with LDAPUserfolder but it just returns you to the index_html file in root. Any help would be much appreciated. Many Thanks, Philip.

Jo, I know HTTP lacks the concept of session and thus the concept of 'being logged in'. This means that some way we have to store on the client side some sort of authentication information and send it back to the server with the HTTP request. Anyway, in my opinion it's not necessary to send username and password with the request every time: the authentication information could be any sort of identifier, tied on the server side with the real username and password (which have to be provided with the first request, of course). Moreover, though HTTP is sessionless Zope could be not, in the sense that (using some sort of client-side storage like cookies, hidden form fields, whatever) it could have built-in the concept of 'logged in user' somehow: are you sure it doesn't? That would mean that Zope is not stateful with respect to the users. Thanks for your help.

Zope Advocacy at Highway Africa Conference
by Jean Jordaan 07 Aug '02

07 Aug '02

Hi all The Highway Africa conference [1] has invited us to take part in a panel discussion on "Open Source as a techonological alternative for Africa", and to present a workshop about using Open Source software for online publishing. With this mail, I'm trolling for advice and input from all you moguls experienced at wowing the crowds ;) I've put together a page with more details and links here: http://www.upfrontsystems.co.za/highwayafrica.html There's also a QuickTopic discussion space here: http://www.quicktopic.com/15/H/Vx6UCXCpB6qK The panel will include representatives of the South African government and from AllAfrica.com, so our contribution should emphasize the role of Open Source in a third-world national and regional context. For the Workshop, which will be taking place in a media lab with workstations for participants, we're considering walking the participants through a Plone [2] portal. Plone is an implementation of the Zope Content Management Framework [3] with a lot of emphasis on an attractive UI and on usability out of the box. The default installation provides a portal with similarity to sites like Kuro5hin, though with a wider application than news publishing: - site visitors can browse, search and comment on content, - members can contribute content (news items, documents, etc), - content participates in a publishing workflow, so that site editors can vet members' content before publishing. Content is also automatically syndicated as RSS, so a Plone portal is open to integration with other news sites. As Highway Africa 2002 is focussed on the media and journalism, rather than on IT professionals, this looks like a reasonable starting point. So what do you think? -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za [1] Highway Africa 2002: Wiring Journalism for development.

keeping track of logged in users
by Mario Bianchi 07 Aug '02

07 Aug '02

Hi list, my questions are about logged in users. Let's say I log in to my Zope-builded site as user 'foo' and do something (e.g. navigate around). Now if I ask for a resource (say the bar.html file) to which foo has exclusive view permission granted, I get that resource (view that bar.html file) without Zope asking for authentication credentials. This means of course that Zope automatically checked that the request of bar.html was made by user foo, and also that Zope knows user foo is currently logged in: the question is HOW could it do it? I have disabled the cookies on my browser (Netscape), cleared the disk and memory cache, erased from the file system the directory used by Netscape as the disk cache, so how could Zope tell that the request of bar.html came from user foo? Based on the IP address of the requestor? Also, how does Zope keep track of the users currently logged in? What data structures does it use? More, there seems to be no way of logging out (except if you're a manager: in this case you can use the logout button from the management interface): if you ask for a resource not publicly accessible, you're prompted to enter userid and password and from that moment on you're logged in, but how can you logout?

I just tar my entire zope directory daily, Data.fs and all to tape. Weekly we do an offsite of our tapes.

I am planning to do an off-site backup of Data.fs on a regular basis and a tarball of the site as configure whenever I modify the configuration.
