November 1999 - Zope

Documentation
by Milind Lele 30 Nov '99

I'm a newbie. I tried reading through Zope documentation and it appears broken. (zdp.zope.org) Any pointers to a good "Begginners' guide" or "Getting Started manual" with lots of examples? TIA - Milind

If I go to /Quena/document_src it gives a 404 not found, but /index_html/document_src prompts me for a login (which is the correct behavior, it's often useful to try out an object method by going directly to it with the web browser, document_src is this sort of method). Perhaps the object is just whacked and needs to be re-created? -Michel

how to clone an instance of a class into another location?
by Andy Pahne 30 Nov '99

30 Nov '99

I tried to add a method (cloneInstance) to my class (myClass) that clones the instance (myInstance) into another folder. I called the method with the link host/path/to/myInstance/cloneInstance. The methods code: <dtml-call "manage_clone(this(),'clone',REQUEST)"> Which gave me the errormessage: The object copy_of_998-X does not support this operation ? Oh, really, doesn't it? So, how can I achieve what I need? And how do I clone an object into another location? Andy

extension stripping fsimport.py
by Ethan Fremen 30 Nov '99

30 Nov '99

Do you use fsimport.py? Sick and tired of all the html documents and images having .blah on the end of them, forcing you to use local namespace strangeness all the time? Use this extremely mild update (2 lines) to fsimport.py and zope-friendly objects (i.e. those that don't turn into "file" objects) will have their extensions stripped. Thanks, -- Ethan "mindlace" Fremen you cannot abdicate responsibility for your ideology.

sequence-start: does it work in 2.01?
by Doug Wyatt 30 Nov '99

30 Nov '99

I've got this little bit of DTML, copied with very minimal changes from the DTML documentation, chapter 6.5.4 (I'm creating hyperlinks to all of the batches that follow the current one): <dtml-in SQL_ShowVerifiedUsers next size=100 start=qs> <dtml-in next-batches mapping> <dtml-unless sequence-start>, </dtml-unless> <a href="<dtml-var document_id><dtml-var sequence-query>qs=<dtml-var batch-start-number>"> <dtml-var batch-start-number> - <dtml-var batch-end-number></a> </dtml-in></dtml-in> For some reason, sequence-start is *always* true -- I tried making it an if and outputting a special character when it's an if. Is this a Zope bug? Or am I doing something wrong? It's not a biggie; I ended up deciding I wanted to display *all* the batches at the top of the display, so I just wrote a little Python snippet to return a list of batch start indices, from which it was relatively painless to generate the links.

How to set-up authentication of pages
by Andres Corrada 30 Nov '99

30 Nov '99

Hi, I would be grateful for pointers to documentation that shows how to require authentication of users accesing a web page. In particular, how does the authentication work? I'm trying to use Apache with Zope and authenticate via Apache's mod_auth_mysql module and failing miserably. By writing <dtml-call "RESPONSE.setStatus('Unauthorized')"> I can trigger authentication but cancelling the authentication gets me the page! Thank you. ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres(a)corrada.com Owner http://www.corrada.com/mamey Mamey Phone: (413) 587-9595 ------------------------------------------------------

z class question
by Sam Gendler 30 Nov '99

30 Nov '99

If I have a ZClass that inherits from DTML Method, and I want to overload one of the functions in DTML Method, how do I go about doing that? --sam

quick question
by Sam Gendler 30 Nov '99

30 Nov '99

Well, I just read all about ZClasses in the Zope Developers Guide, and it is obviously time that I stop mucking about writing Products entirely in Python, and start using ZClasses. What do people recommend as a good example ZClass Product, preferably one that defines much of the application logic in Python, with the interface being done in the ZClass. Michel, I believe that you recommended this approach quite recently, where should I look? --sam

This could be edited and sent back and thus interpretted to obtain the changes and thus the object is update. This seems to me the only general solution for providing a general, cross-platform, non-html interface that will work for existing editors such as emacs and html editors.
