However, non-Zope development groups on campus have asked me: So, what will we do when another version of Zope comes along that will completely break backwards compatibility again? Nothing. Why would yo do anything? Zope3 will not stop working if Zope4 comes along, just as Zope2 has not stopped working when Zope3 came along. Certainly this discussion has to have taken place somewhere before. Oh yeah. Hundreds of thousands of times with different software. It's a variation of the forward compatibility-discussion, but forward compatibility is a myth. Nobody can predict the future. Will the bright minds behind Zope 3 come up with something even brighter and make something completely new? Possibly, we don't know. Or some Ruby guys will come up with it and everybody will shift to a new completely incompatible version of Ruby on Rails. Or Microsoft can suddenly decide to go open source. NOBODY KNOWS. All we can do is guess, and most of our guesses wll be wrong. Therefore: You do today, what works today, and worry about tomorrow when it happens. For example, what did you do in 1998, and did you in 1998 know what you would be doing today? If you in 1998 knew that you were going to have a Zope 2 based website, then they have a point. If you don't, then they don't have a point. :-) Now, how you break that information to management, is nothing I can help you with. ;-) We have as much invested in ColdFusion as we do Zope 2 and there is a perceptual issue here I'm not certain how to correct via education. Ah! But unlike Zope2 or Zope3, ColdFusion *will* break when incompatible versions come out, because it's closed source, so you can't fix the bugs. With open source you can. If the bug is too complex, yo can pay somebody to fix it for with. With ColdFusion, you're up shit creek without a debugger. Clearly Zope 3 does so much more out of the box to support the standards based semantically driven web site we are saying we want in our needs assessment documents, but it is a hard thing to sell. I'm the worst salesman in the world. All I can do is shoot other peoples arguments to pieces. ;-) Second, the existence of Zope 3 has completely shot any support for Zope 2 continuation out of the water in our environment. Is this fair, or is there life left to the Zope 2 tree we've developed some experience in? Should I be considering pitching a Zope 2 solution instead? There is definitely life in Zope2 left.

Right, but when you try to display a page that uses a schema for an object that does not implement that schema, it tries to look up an adapter between the object and the schema. And if that fails, the page will not be displayed. I suspect that may be the reason. Try to not define the schema and see if the page shows up. I don't think that you're right... Anyway, I tried it: The schema is required, I can't leave it undefined.

[Zope3-Users] newbie design questions for UI to external data
Hello, I'm trying to write a zope3 UI for data in an RDBMS with python business logic. (Hence updates shouldn't go directly to the database; queries are probably best off using the marshalling code in business logic as well, but could use direct query if its especially easy.) I was trying to adapt Stephan Ritcher's Zope3 book examples, but am getting a bit snarled with escaping from/interacting with the ZODB. For a collection of objects that live in the DDBMS, should I try to implement a collection object that itself lives in the ZODB (inherits from Persistent, implements IContainer), but really performs a query to get its data? Then I need to mark actual contents volatile (?) Is there a hook to set the volatile contents? Also, it would be good to have a simple admin object in the ZODB that has DB connection info. Putting one there and making it accessible via Zope3 seems easy enough -- just inherit from Persistent But how do I access this info from, say, my collection object(s). Does Persistent generate a standard key? Or should I have one big database object in ZODB that has attributes for the connection, and also attributes for each of the collections. This seems easy enough, but then I wonder if the zcml config will become tricky, as I would have to declare forms for attributes of instances (somehow)? When using the standard forms, I got errors for not setting __name__ and __parent__ on my contained objects. The first was easy enough, but who is supposed to set __parent__? I want to use standard forms if possible for the moment, as I am trying to get up a prototype fast. Eventually I will need a paged view. Is there one out there to use? In general, if there is a good example of something like I am trying to do, I would be grateful if someone could point me to it. - Shaun Cutts ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] Absolute url of an object
Hi, Sorry if I ask a question that is already asked a gazillion times, but I was not able to find the obvious answer. I'm rather new to Zope 3 and I have done a fair amount of Zope 2 development and was used to be able to create dynamic menus by iterating over the objects in the root container (site root) and traversing all the way down (or as far as i wanted). That was sort of easy because every object in Zope 2 has an absolute_url method as well as a title_or_id method. But although I understand Zope 3 has something like that too, I'm unclear how to achieve that every object provides an absolute_url method. Possibly Zope 3 has a far superior way of achiving the same goal. As a Zope 3 newbie I understand Zope 3 aims to require being explicit, yet I did like some of the implicit behavior of Zope 2 a lot. For instance I still think acquisition is bad by definition.. Maybe you should be able to turn it on or off at the folder level. A related questions is: is there an obvious way to get the site url (or object) other then just knowing the name? Can anyone point me in the right direction? BTW I have Stephan's book and ordered Phillip's book but that didn't arrive yet. Thanks Paulus ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Florian In your view.py is the syntax when you set form_fields valid, I haven't seen it before: form_fields = IRegistrationForm I usually do it by (from zope.formlib import form) form_fields = form.Fields(IRegistrationForm) Alen ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Absolute url of an object
Hi, OK, thanks to Alen and with some further digging, I can sort of answering my own question, I found some answers here: zope3-for-zope2-developers.pdf from Phillip von Weitershausen. Thanks Phillip for thinking of these legions of poor old fashioned zopistas! ;-) So for the other newbies out there (if they search the archives later): * from Python do this: zapi.getView(obj, 'absolute_url', request) # obviously import zapi first * from a page template: obj/@@absolute_url Also without doing any extra, it seems that objects don't know their name anymore. No getId() or title_or_id(). But as Alen pointed out the parent normally does some magic, so: you have __name__ (id in Zope 2 speak) and __parent__ (is obj.getParent() in Zope 2) Mmm, I guess I'm gonna roll my own ordered containers and pages that have a title attribute. Cheers, Paulus Paulus Zegwaard wrote: Hi, Sorry if I ask a question that is already asked a gazillion times, but I was not able to find the obvious answer. I'm rather new to Zope 3 and I have done a fair amount of Zope 2 development and was used to be able to create dynamic menus by iterating over the objects in the root container (site root) and traversing all the way down (or as far as i wanted). That was sort of easy because every object in Zope 2 has an absolute_url method as well as a title_or_id method. But although I understand Zope 3 has something like that too, I'm unclear how to achieve that every object provides an absolute_url method. Possibly Zope 3 has a far superior way of achiving the same goal. As a Zope 3 newbie I understand Zope 3 aims to require being explicit, yet I did like some of the implicit behavior of Zope 2 a lot. For instance I still think acquisition is bad by definition.. Maybe you should be able to turn it on or off at the folder level. A related questions is: is there an obvious way to get the site url (or object) other then just knowing the name? Can anyone point me in the right direction? BTW I have Stephan's book and ordered Phillip's book but that didn't arrive yet.
