I'm sorry, but "functions" are no more easy to >document than "object hierarchies". (OOP theory would state quite the >opposite, in fact.) True. I have grown to think, that Zope actually makes lots of sense -- after one gets over the first steps and un-learn the way of doing applications the way one has previously done with asp or php. Problem is that on the path to the first stage of awareness is a whole lot of big problems and stones to bash your head into. And it takes a great effort to keep on going. >Could it be Zope Corp's lack of prioritization? Maybe Zope Corp. >management believes that "if you're busy writing docs, you're not busy >developing", and so has set a mandate. Or more likely, Zope Corp just >has a developer-centric company culture, and we all know how much >developers like to write docs (right, Andreas?

No, developers are not >happy retrofitting docs for production-level code. But as somebody who >stuck my neck out for Zope, and is now realizing how hard it is to find >up-to-date info, I think this is a fair thing to ask of Zope Corp. What if Zope corporation would hire an editor to keep up the community and documentation. I don't believe that just the documentation solves problems, there should be someone coordinating or helping different development efforts to work together. Integrate good tips from the mailing lists to the knowledgebases etc. Recruite people to write or update articles about different subjects, based on the buzz on the community. I mean there is lots of need for help for high end developers, but there is the possibility to dive into the code. There is even mor eto be done on the beginning level, to help more and more Zope users on their way and support good programming practises and designs. This is exactly what I would have liked to see a couple of months ago! And what if this would happen? Well for starters I would like to participate and contribute in areas that I migth be able to help someone else. One important note also: There should be CLEAR guidelines of where to find and distribute information. Zope-mailinglist is a great place, but also a dumping ground for all sort of requests from beginners to advanced users. It is also damn hard to try to find the information, even though I would know that I saw the guide somewhere - was it on the mailinglist, with which keywords, was it a howto, or on different sites outside Zope Corps. reach. And this - as far as I can tell - would require someone to coordinate and manage the information. -huima

CookieCrumbler logout problems
by aleciesse＠infinito.it 08 Mar '02

08 Mar '02

I'm trying and managing with CookieCrumbler (as you all suggested). I've got a logout problem: when I try to logout with the standard logged_out method, it always goes to the "You're using HTTP based Authentication" part. the prbole is that AUTHENTICADED_USER in REQUEST can't be "Anonymous User" because no one sets it! Have I to set it by hand in some DTML-or-Python script? Many thanks Alex Cordero Prova Genie Disco Virtuale: 10 gg. gratis per te! Per attivarlo clicca qui http://www.genie.it/provadiscovirtuale

How to let user get login page without HTTP "redirect" with exUserFolder?
by Ren Bing 08 Mar '02

08 Mar '02

Hi, I am quite new to zope. I just installed exUserFolder and tried it. It works excellent. However, I noticed that before the login page appear, the "stack trackback" and some error message page glimpsed on the browser. I then find that the browser is redirected to the login form with HTTP redirect. I don't want to let user notice the redirect, if the connection is slow, user would be confused by the error message. I hope to redirect to the login page at the "server side". How can I do this? Thanks very much! Ren Bing

Error codes
by Graham King 08 Mar '02

08 Mar '02

This may have been done to death before.... bear with me. Have searched around a fair bit for the meaning of "error codes", as in the ubiquitous "Aiieee! 10318 exited with error code: 138" Can anybody direct me to a repository where these specific errors are documented, what they mean, and how many there might be? (My memories of shelves full of books of documentation, and the biblical "System Error Messages and Codes", are receding even as mainframes wisp away into the mists of Avalonic myth). cheers Graham

Help: ZPT + Product Devel: How do I call a PageTemplateFile from a manage_addMyProduct() function?
by jkinsley 08 Mar '02

08 Mar '02

Hi, I am developing a product that uses PageTemplates for its management forms. While this works, my problem arises in the fact that I want to perform some tests before the PageTemplate form is called so that the results of the tests are available in the form. # When I do this, the form is properly displayed, but the tests are # not performed. manage_addMyProductForm=PageTemplateFile('forms/manage_addMyProductForm.pt', globals(), __name__='manage_addMyProductForm') # I want to be able to do this, but I can not figure out how to # return the form. def manage_addMyProductForm(client, REQUEST, *args, **kw): """Returns form to add My Product.""" if test1: pass_test1=1 else: pass_test1=0 if not test2: pass_test2=1 else: pass_test2=0 form=PageTemplateFile('forms/manage_addMyProductForm.pt', globals(), __name__='manage_addMyProductFormTmpl') # Here is where my problem is. # This fails with an AttributeError on other in # Shared.DC.Scripts.Bindings._getTraverseSubpath # Where REQUEST.other is used. return form(client, REQUEST, args=args, pass_test1=pass_test1, pass_test2=pass_test2) Finally in the form template, I want to be able to do something like this: <tr tal:condition="not:pass_test1"> <td>Display Row</td> </tr> <tr tal:condition="pass_test2"> <td>Display Row</td> </tr> Any advice will be greatly appreciated.

Aquiring question
by Antonio Beamud Montero 08 Mar '02

08 Mar '02

Hello all: Suposse I have the next structure: A (Folder) with a dictionary with properties x = PersistenMapping() def get_property(self, y): return x[y] B inside A is another folder, and in a dmtl method of B I want to call get_property() not on B, but on A, (this manner I can use the x dicctionary, i.e. acquire the x dicctionary too)... How I can do this? Is it possible? In the dtml method get_property is evaluated on B, and it doesn't find a dictionary instance...
