where port num gone
by Andy Heath 12 Mar '00

12 Mar '00

I have this root ltscimages someimage somefolder somedtlmdoc and I'm running both apache and zope. Some pages get served zope-->apache and some direct from zope. ZServer is running on 8080. Within somedtmldoc I want an image from ltscimages. This code <dtml-var "ltscimages.someimage"> produces a reference to the image but without the port number. In the ouput html I want http://host:8080/ltecimages/someimage but I get http://host/ltscimages/someimage I can work around this by serving the image via the zope-->apache method but that's crummy - I want only to use apache when I have to because of the efficiency effect. Putting the port in explicity is also crummy because its less transportable. How can I either 1. always get the port num in or 2. get the port in if its not the default 80. Elswhere in the same code absolute_url() does this correctly for code inside a tree. Would there be a way to use this here? Sorry for so many newbie q's. I promise I'll give back when I can.

Is it possible to format a date to GMT or in general in other timezone other zone? I have read through the Quick reference but do not have answer. The ToZone(z) is listed there under DateTime. But How can I use that? Moreover, how can I make date-time calculate : adding 3 days to current time. Add 2 minutes to current time, etc. Rgs, Kent Sin

Something like: http://www.whatever.com/__no_before_traverse__/path/to/rule/manage_main' Then go to the management screen and UNDO that very last thing that causes SiteAccess to get into infinite loop. If Zope is not problem, do you have Apache re-write rules somewhere modifying your URLs? The first time I used SiteAccess was also my last time. It was so freaking scary to have a hang-up situation where you cannot do anything except cry in desperation. :) Several people have reported problems with SiteAccess. It's not that I don't think SiteAccess is great: its concept is great, just that I don't ever want to get into this kind of scary situation again. :) I am waiting another few months before I get more reliable version of SiteAccess or its equivalent in Zope. And no, thanks, I won't be a guinea pig to reproduce the bug. :) Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Re. Client-side Zope
by Jerry Spicklemire 12 Mar '00

12 Mar '00

This concept was kicked off by a specific need that led to discussions of polling, XML-RPC, Java RMI, JavaScript, and others that I can't recall. But, an unrelated need brought it home last night. The ZSchool project will at some point involve lot's of folks who won't be online constantly*, and suddenly Client Side Zope starts to look interesting. Keep in mind, it's Zope! For those of you who have sworn off all things Microsoft and have grown accustomed to the "joys" of compiling and tweaking Zope / Apache / etc. on all varieties of *n*x, you may not realize that getting Zope running on Windows takes about five minutes. Thats five minutes for a newbie. It's just a Windows "Install". Now, if anyone mentioned Client Side Oracle Application Server, or Client Side Lotus Notes, we'd know they'd lost it. But Zope is actually small and nonintrusive enough to pull this off. Think about a world full of Zopelets, on all those nifty palm thingies. Your local WorldPilot could sync up with a central WorldPilot periodically, but you'd still have "all" your data available while you're off-line*. Same with Xen Project Manager, zSchedule, etc. Of course that's just the beginning. A generation of new apps we've not dreamed of yet that could make this thing explode, when we figure out how to really exploit XML-RPC, and whatever comes next! Later, Jerry S. * I'm not holding my breath for us all to have wireless persistent IP anytime soon . . .

Re: [Zope] dtml-var behavior
by Sin Hang Kin 12 Mar '00

12 Mar '00

I am writing a method, which apply to a object and try to wrap the object with some thing, This is <html><head>....</head> <body><table><tr>... <dtml-var this> </tr> </table> .... </body> </html> So to keep all start tags and end tags in the same object. I can do that for a folder by making the method call index_html and call the index_htm object. But I want to publish anyobject by adding this method to it: abc/publish will warp abc with the apropriate html codes which traditionally in zope is done by header, var, footer. which might result in the opening tags in header and end tags left in footer.

Calling a Z SQL Method directly
by Douglas Bates 12 Mar '00

12 Mar '00

I am a little confused about how to call a Z SQL Method directly from within a DTML document or a DTML Method. The application is web-based access to a bibliographic database. I have one Z SQL Method that looks up publications by author names, or by words in the title, or by keywords. I set up a search interface to that method. I am now trying to modify the DTML Method for generating a report from such a query. I have read the Z SQL Method User's Guide but apparently I haven't understood it completely. To make things definite I will describe a simple case. Suppose I look up one author's name. The Z SQL Method is called search_author. The columns it returns include the "id" for each reference listing, the "type", the "year", and the "title". I have also created a Z SQL Method called return_authors that takes a single argument "id" and returns the names of the authors, one per row, in the correct order for the publication. Another Z SQL Method, return_journal, also takes an "id" number and returns the title of the journal, the volume and number, the beginning page and the final page of the article. While I am processing the results of search_author in the DTML method, I would like to be able to call return_authors and return_journal directly. It is not clear to me how I do this. I had hoped that I could use a dtml-in tag to call these methods while I was within another dtml-in but either I am misinterpreting the effect of dtml-in or I haven't got the sequence right. What I was trying looked like <dtml-in search_author size=50 start=query_start> ... <tr> <td><dtml-var year null=""></td> <td><dtml-var title null=""></td> <td><dtml-in return_authors start=query_start> <dtml-var name>; </dtml-in></td> <dtml-in return_journal_info start=query_start> <td><dtml-var title></td> <td><dtml-var vol null=""></td> <td><dtml-var bpg null="">- <dtml-var epg null=""></td> </dtml-in> </tr> ... </dtml-in> I was hoping that the <dtml-var id> from within the <dtml-in> loop would be propagated to a call to return_authors or to return_journal. I understand that I can use a URL to call the Z SQL Method but I am hoping I can do it "inline", as it were. I would appreciate any suggestions. -- Douglas Bates bates(a)stat.wisc.edu Statistics Department 608/262-2598 University of Wisconsin - Madison http://www.stat.wisc.edu/~bates/
