Re: [Zope3-Users] Required choice without default value in formlib
On Friday 12 January 2007 05:02, Thierry Florac wrote: I use formlib to handle my forms. In a AddForm, how can I have a required choice property, using a dynamic vocabulary, without a default selected value ? You would have to write your own widget that displays a blank value by default. If the blank value is not changed by the user to a real value, then the widget throws an error during validation. I think by mapping the blank value to the missing value willdo the trick, so the custom widget would be a simple extension to the existing one.

Re: [Zope3-Users] interview for my diploma thesis about Zope 3 in education
On Monday 22 January 2007 07:08, Dominique Lederer wrote: For my diploma thesis, i would like to ask you to anwer or discuss a few questions, to see, what you think about this. (of course i will cite all the stuff) I hope it is not too late. Here they are: * Do you think Zope (3) can be used at school or university level to support topics in computer science education? What topics would you recommend? Why? Yes, like Java is taught because of it's object orientation, Zope 3 should be taught because of its component architecture. For me, the mental jump from object-oriented to component-oriented design is as big as the one from procedural to object-oriented programming. Further, I think that Zope 3 is a great tool for education, because it is the only Open Source software that embraces test-driven development. Zope 3 is a prime example of why automated tests are so important. In addition, the *.txt files are just beautiful examples of great technical writing and documentation. * How would you convince someone who is in charge to use Zope 3 in his curriculum? I think it would be a difficult sell. Zope 3 is, afterall, a Web application server. Only a small fraction of CS problems can be solved with a Web application. A programming language, on the other hand, can help solve a very wide range of problems. I think that Zope 3 as the full server only makes sense in a Web-development class. For general classes, I would only suggest libraries that illustrate very common patterns: zope.component, zope.interfaces, zope.event, zope.security, ... * How do you see Component Based Software Engineering (CBSE) related to Zope 3? What are the differences? Is Zope 3 an alternative for other component based frameworks in the industry and why? Zope 3 is CBSE. Well, in Python there is only one component architecture and this is zope.component. Other programming languages offer their own solutions. So the choice of the CA is largely based on your choice of programming language and your type of application. For example, CORBA would not fit the Web nicely. * How do you see the future of Zope? Where do you (want to) see it in 2 years? The largest probelm for Zope 3 is currently the rate of adoption. Another way of looking at it is to say that people need to come out of the closet. Other technologies tend to steal the show with a lot of hype, but Zope 3 is well equipped to stand up to them. I think a lot of people know that, but they are afraid to spread the word. We really need more case studies and project reports. In 2 years, I hope that Zope 3 has grown to an application framework that competes with the big Java bullies. I do not think that we should even compare ourselves to PHP, RoR, Turbogears or Django anymore. We should talk about why we think we are better and more productive than people with JBoss. This will require a bit of marketing effort and more non-coding committments by people in the community.
