- Zope - Zope lists

trees, hypernews and frames
by Andy Heath 10 Mar '00

10 Mar '00

Sorry, this is involved and takes a lot of words to explain. I'm building a zope site which also serves HyperNews discussions. Apache and Zserver are working well together. What I have is a tree widget iterating over a folder, some of whose elements are treated as hyperlinks to hypernews discussions. Base articles for discussions are in the contents of the zope items so .... when you click on an element in the tree it follows a link to hypernews and the hypernews fetches the contents of the "same item" you just clicked on. This is a roundabout way but the only way I know to keep my hypernews headers and stuff in zope It does all work well but.... My first implementation had a two column table with the tree on the left and the particular discussion on the right. This worked well logically but wasn't too visually appealing because as you expanded/collapsed tree branches everything moved around on the page. So I re-organised it to use frames - a header frame, then two columns (tree in one, discussion in the other) and a footer and this works very well. My problem is now this - except for the top one the frames on the page do not include what in the former implementation was the header (i.e. the fancy bit at the top that gives context and doesn't move). Now its possible and common to access the hypernews discussions without coming in through the zope home page with the tree widget. It is common to do so because when hypernews sends email it puts a hyperlink to the item in the email which does just that. When this hyperlink is followed the page is fetched from zope but of course the fancy header isn't there. Since its no longer displayed inside the frameset the header needs to be displayed as well but isn't. That's the crunch. How to get the fancy header served when its displayed outside the frameset but not served when its inside. If it were all in zope then this could be done by passing a variable value so the page could know how it was called but hypernews does not pass on anything like this when it fetches content from other servers. Anyone think of a way round this? Please copy replies to a.k.heath(a)open.ac.uk as I take the digest.

Linux is not about marketing. It is not about world domination. We specifically do not care about this :-) Now, digicool is a company, and they probably DO care about this. Making Zope Free Software is a great way for them -- and us -- to benefit. So your comments should be addressed at them if you want them to make the sale. Not me, a Linux hacker. > As one of my colleagues pointed out, the problem starts with the name. > (Somebody out there is hyping what they call Linux' next-generating GUI. > And it's called... GNOME. What's wrong with this picture?) I don't care > myself, but I recognize the problem. But see again, Free Software is not about marketing. The name is irrelevant to us. Free Software is about what's *right* and what *works*. We leave the marketing to those that want to do it (such as digital creations, or whomever else). So again, write to digital creations' marketing dept. :-) -- John

WorldPilot Acquisition?
by Mike Fletcher 10 Mar '00

10 Mar '00

I've been mucking around trying to get Acquisition to work with WorldPilot objects (I want to define methods/documents that can query WorldPilot's "normal" objects (Events, Address Cards, Notes, Todos, etceteras), and the collections of the same. So far no luck (I don't really understand everything going on under the covers of either Zope _or_ WorldPilot, so I'm not likely applying pressure at the right points). I've been adding Acquisition.Implicit to the hierarchies of just about every object with no luck so far. Does anyone have ideas on how to go forward? Could I alter the "normal" objects in some way to make them accessible at a higher-level (for example, if I could get at the objects in a flat collection, I could run my queries against them, using their types to sort into virtual collections). I suppose, in a pinch, I could just read the local files and construct a query against them, but that seems... well, too incredibly hacky. Incidentally, why does WP use all these custom storage mechanisms? The actual objects don't seem too complex, and the interface doesn't _seem_ like it would require the support. Ideas appreciated, Mike __________________________________ Mike C. Fletcher Designer, VR Plumber http://members.home.com/mcfletch

Greetings... After trying constructing an entirely NEW zope install, and winding up with not being able to import the backup of my site, I decided to reboot. Strangely, everything is working again. Oh well... at least i've learned some more about the innards of Zope. Thanks for all those who joined me in my futile search for an answer. -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Hello (yet again) Zopists, I regret that I have so many questions... I had this working in older versions of Zope. Has this been updated to another format? <a href="/queries/SearchResultPage?theid=<dtml-var the_id>">link</a> or was I using it the hard way? virtually, Joseph A.

Zope style consider harmful
by Sin Hang Kin 10 Mar '00

10 Mar '00

Please do not try to match the start tag and end tag again and again in zope. Please come to see the http://zope.org/Members/kentsin and get the root.zexp for evaluation. This is a set of method/attributes which will publish the folder's index_htm document The methods will generate the doctype, stylesheet, javascript, rdf for the document. It can be configure by setting certain attributes. Hope this will get into the zope mainstream. Rgs, Kent Sin
