How to start developing in zope
by Firestar 30 Jul '00

30 Jul '00

Hi, I have read through(and tried out) the tutorials and Guides at Zope.org, and now eager to port my company's website over to Zope. (The website was originally programmed in PHP) In my original design, I used OOP mainly. I defined each section(e.g. News, Events, Products) as a class by itself, inheriting from a "main" superclass. Each class would contain their own set of attributes(such as font-color, title) and methods(e.g. display news headline, or display events schedule). Common attributes & method that are widely used are placed(shared) in the "main" class(e.g. talking to MySQL database). So, if there's any changes or updates, inheritance will propagate the changes to the rest of the subclasses. (As usual, management will require extra features such as personalised page, membership or web-based email to be added in future. Hopefully, this kind of structure would make adding new features a breeze.) I believe Zope is based on a similar way (and much more powerful). I was wondering how shld i start something like this in Zope - i read abt ZClasses(where you can define your own Folders), Products(for defining yr business logic) and DTML(for dynamic data display). Your opinions will be much appreciated. regards, firestar ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Moving site from dev to prod.
by Jeff Nielsen 30 Jul '00

30 Jul '00

I can't quite seem to figure out how to move my web site from my development machine to my production machine with Zope v2.1.x. Under Zope v1.0.9, I simply copy the data.bbb file. Under Zope v2.1.x, this file seems to be data.fs, but copying it doesn't seem to work as I get a NameError on REQUEST. I've also tried to use the import/export capability, but I can't figure out how to get the entire site to export. I been through the zope.org sites, docs and recent emails, but can't seem to find guidance on this topic. My development machine is Zope v2.1.4 on NT and the production machine is Zopev2.1.6 on NT. Both installs use FSSession v0.3.1 and LocalFS v0.1.5 If someone could guide me to documentation, or give me the basics of what needs to happen, I would appreciate it. Thanks. ----------------------- Jeff Nielsen http://www.UgoFast.com/ "Where U Go Fast"

Can multiple processes access a ZODB3 file?
by Ross Boylan 30 Jul '00

30 Jul '00

If I have Zope running, using ZODB3 on Data.fs, can a separate process also use ZODB3 to access Data.fs? I have my suspicions, but I'm not sure. I'm interested in this because I'm in the middle of a balloting period. People email me their ballots. I will need to check them for validity, send out confirmation or error messages, and eventually tally the results. I definitely want a persistent store, so ZODB seems good. Also, I eventually would like this to be a Zope product, with people able to access the results on the web (and, in the future, vote on the web). But getting it Zoped may be too much work in the short run. So, I'll have a Zope server running on my Debian system, and another process will be going through the mail. It would be more straightforwad if that other process worked directly with the database, rather than going through Zope via http or xml-rpc or something similar. So I'm wondering if that's possible. I can always take the indirect route if, as I suspect, that's necessary. I'm cribbing from parts of the Poll product as appropriate. The polling machinery is considerably more complex though: a restricted list of voters, various muckings around to get the info out of the email, and preference voting (1 for first choice, 2 for second, etc with an instant run off). I know Zeo is more in the multi-process space, but I don't want to use it for this project because I don't have time to learn it; it's alpha; and it seems like overkill for my problem.

dtml-in syntax
by Kyle Burnett 30 Jul '00

30 Jul '00

so i have this loop and i want to count a variable: <dtml-in wherever> <dtml-if sequence-start> <dtml-var count-id> </dtml-if> </dtml-in> but what i really want to count is specific values for id. so let's say id=='value1', i want to try and do the following: <dtml-in wherever> <dtml-if sequence-start> <dtml-var "count-id=='value1'"> </dtml-if> </dtml-in> but no luck. and i have tried several other make-shift syntaxes to no avail. i do have some other logic that i could use over the course of the loop to determine the count of distinct values but i was try to do it in far less code. anyone got an idea of how to rig this? thanks in advance, kyle

Re: [Zope] What is the best method to enter more attributes about DTL Document?

Marcin Kasperski writes: > Short and probably obvious problem: what can I do to be asked for more > properties while creating DTML Document (say I wanna be asked about > description and keywords which I use in meta tags)? Maybe, customize "OFS/methodAdd.dtml" and "OFS/documentAdd.dtml". You need to change the "action", too, and do something with the new properties. The code for this handling is in "OFS/DTMLMethod.py" and "OFS/DTMLDocument.py", respectively. Dieter

Re: [Zope] probs. with vti xxxx folders - anyone using FrontPage + WebDAV ???
by Dieter Maurer 30 Jul '00

Chris Withers writes: > I wonder why starting folders with _ is so bad in Zope? In the time, when everything was allowed what was not explicitely forbidden, an easy way was necessary to forbid access. Jim (and, therefore, Zope) used: anything starting with "_" is private: no DTML access, no Web access. Now, with the change to a security policy "Everything is forbidden when not explicitely allowed", the need for such a rule based on naming dwindles. Maybe, it will disappear sometime in the future.
