Passing variables to a DTML method ...
by Darran Edmundson 23 Sep '99

23 Sep '99

Could someone explain how to pass variables to a DTML method? For example, if I have the following in a DTML method: <dtml-call "REQUEST.set('testvar', 'value')"> <dtml-var "calledmethod(REQUEST)"> How can calledmethod access the variable testvar? I thought that calledmethod gets the REQUEST namespace on thus <dtml-var testvar> would work. I read Amos' How-to: http://www.zope.org/Documentation/How-To/AdvancedDTML but I'm still struggling. Cheers, Darran. -- Darran Edmundson [Darran.Edmundson(a)anu.edu.au]

Zope.org makes heavy use of ZCatalog. A good starting point will be the ZCatalog tutorial http://www.zope.org/Documentation/How-To/ZCatalogTutorial The general idea is something like this: 1) Set up a catalog for the site 2) Use the "Find" feature to load objects into the catalog (unless you have created your own "CatalogAware" objects... that's a bit more advanced, but not too difficult once you've played around with it some more). 3) Create a "Z Search Interface". This lets you create a search form and report in one step. The ZCatalog Tutorial has some example search code as well. >Aside: It would be great to see all of the methods for the zope.org site, >are these available? I know you can see the DTML source, but I would like to >see what's behind >  >  > etc... If you look at the URL when you click the DTML Source link, that gives you an idea what to do...

my last mod_rewrite question
by Andy Pahne 23 Sep '99

23 Sep '99

I think managed half the way of this mod_rewrite-stuff, it was not easy for an newbie like me. I setted up this folder structure in Zope root-folder | projectsite | ------------------------ | | site1 site2 I have a virtual domain called www.zopetest.net and I designed the rewrite-rule in that manner, that zopetests' root-folder referrs to Zope's /root/projectsite/site1 That works fine, I can access the site, and passing authentification headers works as well, but if I view the management-window, it tells me, that my location is: /projectsite/site1//projectsite/site1//projectsite/site1/......... I know that Zope works that way, but I'm not sure, if the people responsible for maintaining the projectsite will be confused about this. I did not forget to put the l-flag (yes, the letter l and not the digit 1) into the options of RewriteRule, so I wonder why mod_rewrite works a second time on the already rewritten URL Any Suggestions?

Generating sequence UID?
by LD Landis 23 Sep '99

23 Sep '99

Hi, I have a ZSQL method db_sequence(name) which increments the 'id' of sequence 'name'... When run ('view') it prompts for the name, and returns a result that has the title 'id' and the next value. So far so good. Now, I want to have another db_contact() method that gets its stuff from REQUEST, which I have working, but I have been unable to get db_contact() to call db_sequence('contact_id'). I've tried various syntactic things and haven't won yet... The following is not any of the variety of things I've tried, but I hope suggests what I want: db_sequence(name) (What I have works, even if not update sequence set id = id + 1 exactly this) where name = <dtml-sqlvar name type=string> db_category(--no parameters--) insert into category (category_id, name, field...field) values ( <dtml-call db_sequence('category')>, <dtml-with REQUEST> <dtml-sqlvar name type=string>, <dtml-sqlvar ... type=string>, ... <dtml-sqlvar ... type=string> </dtml-with> ) -- Cheers, --ldl ----------------------------------------------------------------------------- LD Landis ldl(a)HealthPartners.Com N0YRQ Voice 612/883-5511 Fax 612/883-6363 HealthPartners, 8100 34th Avenue So, PO Box 1309, Minneapolis, MN 55440-1309 Shape your life not from your memories, but from your hopes.

ZClasses vs Products (extending UserFolder)
by Bjorn Stabell 23 Sep '99

23 Sep '99

Hi guys, There are a lot of ways of extending Zope; Pros and cons of Products, ZClasses, PythonMethods, ExternalMethods, just to my feeble knowledge. Maybe too many. I'm not sure which ways are best in which cases. Anyone identified the pros and cons? Specifically we have an application in mind. It and our design decisions are described below: An HR application, letting users register their resume and personalia, and while browsing job ads, just attach a cover letter to apply (your resume is already in your user record). The HR person should be able to post/unpost as well as add/edit/delete job applications, as well as review job applications (resume/personalia/cover letter). >From an OO perspective, it seems natural to extend UserFolders by just adding resume information to the User objects. That way we'll inherit all the user registration code. I guess the job ads should be implemented as objects in a folder. The design decisions we're faced with are: 1 UserFolder vs ZClasses 1a. Should/can we easily extend the UserFolder as described above. That would essentially mean making a new product called ResumeUserFolder that would inherit from UserFolder and extend the relevant functions. Looking at the code for UserFolder, however, it seems it's pretty hardcoded to support only the properties it already supports. If we add any properties, how do we make sure they'll be persistent? 1b. Should we perhaps use ZClasses and create our own Applicant, Application, and JobAd classes. Then, is it still easy to do all the logging in? Do we need PythonMethods? 2 Login/Logout - provide user-friendly path for new user We're struggling to see how to best implement logging in. We don't like the browser's own authentication popup window asking you to fill in a username and password as most users will be scared by it, particularly since it doesn't say how to actually register. Still, I like that the authentication is externalized in this way instead of being spread throughout the site in the form of small login boxes. But, is it possible to have our own web page show up instead of the browser login box? Difference being our login page would have explanations on how to become a new user. Kind regards, -- Bjorn Stabell <bjorn(a)stabell.priv.no>

Acquisition? Did I just lose my Zen?
by Martijn Pieters 23 Sep '99

23 Sep '99

And I thougt I had it covered.... I have the following structure: / index_html (checks a cookie, gives a frameset or a redirect to /noframes/home (frameset loads /home)) home (content) standard_html_header (together define my page standard_html_footer layout) frames/ <- Framesets standard_html_header (define a frameset that standard_html_footer loads the same URL minus index_html the /frames prefix) nav (navigational frame) noframes/ <- No framesets standard_html_header (define a layout with standard_html_footer navigation in a table) index_html All objects are either Folders or DTML Methods. So far so good, this works like charm. With acquisition, the home document can be viewed with and without a frameset. See for yourself at: http://mj.antraciet.nl/ But then I make another Folder, lets say Personal, and define a index_html in that Folder: Personal/ index_html Calling http://mj.antraciet.nl/Personal/ works fine, but when I call http://mj.antraciet.nl/frames/Personal/ the same layout appears as the previous URL. De standard_html_header and -_footer from the root are being used, not the ones in the frames/ Folder! The same goes for noframes/. Now either I have to rethink my Zope Zen, or something is very wrong here. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

FYI: Sybase Level 3 DA
by Paul Everitt 23 Sep '99

23 Sep '99

Hello all. Digital Creations has received enough funding to create a Level 3 Sybase database adapter. We had a quiet "pass-the-hat" fundraising effort, and although we didn't receive complete funding, we received enough to get started on it. The plan is to make it initially available, probably next week, to the people doing the funding. They will get it for some period of time, certainly much more than a month, and then we will make it publicly available. If you'd like to get in on the fundraising effort to support the creation of a Sybase database adapter and get an early release, please send me an email. --Paul

A better way...
by Arnaud Lecat 23 Sep '99

23 Sep '99

Hi... here's a piece of code... <dtml-with expr="PARENTS[_.len(PARENTS)-2]"> <dtml-if "navigate_filter('donav','yes',_.None)"> <TABLE BORDER=1 CELLPADDING=0 CELLSPACING=0 width="130"> <dtml-in "navigate_filter('donav','yes',_.None)" skip_unauthorized=1> <TR><TD>Folder : <dtml-var title></TD></TR> </dtml-in> </TABLE> </dtml-if> </dtml-with> I'm sure there's a better way to do for grouping the dtml-if and dtml-in in this case...

Except if the user selects ZERO items in which case the browser usually omits the variable (e.g., removeLine) from the REQUEST. You need to check for its existence first... <dtml-if removeLine> <dtml-in removeLine> Do something here. </dtml-in> <dtml-else> Hmm.. they selected zero options </dtml-if> --Rob
