script or external method ?
by debugworld-linux＠yahoo.it 04 Apr '05

04 Apr '05

Hi all, i'm a new user of Zope; i'm studing it since two weeks and i think it's very interesting, 'cause has the same power of j2ee application server but it is much more easy to use! While i was developing my first Zope application i fell into this trouble: i would like to write a script that create a folder, put some file in it, and set some properties. The code i've writed imports date object from datetime package: this makes it doesn't work like a script (python), so i adapt code as an external method; but when i run the method Zope says that he can't find symbol 'container'... (mumble) Well, 2 are the questions: First, what i've to do to get service variable like like container, context, request, etc.. ? Which are differences between script and external method coding? i remember that the zope book indicates only imports. Ok, thank you for reading..

getting all fields from dynamic checkboxes
by Dan E 04 Apr '05

04 Apr '05

Hi, Has anyone found a way to get a list of boolean values from dynamically created checkboxes. I have created a bunch of checkboxes within a repeat loop like this: <input type="checkbox" class="noborder" name="cb_array:list:int" tal:attributes="tabindex tabindex/next; checked python:test(curr_prop, 'checked', None);"> but when I access the cb_array from my python script, I only get the checked values (and I can no longer match the values up with the checkbox they came from). any help on this would be appreciated. thanks in advance, Dan

role, user defined roles, and inclusion
by Dennis Allison 04 Apr '05

04 Apr '05

I guess I am confused about roles and how they are interpreted. A quick check of the Zope Book didn't provide the answer. It would be nice if there were an index for the book. I've always thought of the roles as flags without an deeper semantics. But I am seeing some behavior that suggests I my model may be wrong. Are the standard roles (anonymous, authorized_user, manager) inclusive? By inclusive I mean that an authorized_user is also treated as an anonymous_user and that a manager is also anonymous and an authorized_user. Are user_defined roles inclusive? Or are they separate and distinct? If `wizard` is a user defined role, is it also an authorized_user for security purposes? I suspect the real answer here is "it depends upon the implementation". If that's the case, what is the best practice used in the Zope system.

Sorry for the delay. You would likely get quicker response if you had replied on the list. The DBTab product is not compatible with Zope >= 2.7. Its functionality has been moved into the core, and is now configured using the normal 'zope.conf' config file (note that the sessions machinery configures the temporary storage mounted at '/temp_folder' this way). > Thank you. > > (Excuse my english) No problem. - -- =============================================================== Tres Seaver tseaver(a)zope.com Zope Corporation "Zope Dealers" http://www.zope.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCUWdjGqWXf00rNCgRAjJzAJ9dQwaFwS/0v+zekJijWqWx9bWVcwCaA8k+ zQ5SkupTJzpRuFSo09kojOU= =bjbE -----END PGP SIGNATURE-----

Re: [Zope] Does anyone care whether we deprecate ZClasses?
by AM Thomas 04 Apr '05

04 Apr '05

I agree that ZClasses are not good to use. However, I have a product based on ZClasses that I wrote several years ago (after reading the printed Zope book - doh!), and it's working well for several of my clients. If future versions of Zope were to not support it, that would be a huge problem for me... unless there were some utility that would allow me to export my ZClasses to a regular file-system product. Thanks, AM

RSS feed: post-processing?
by MILLER Eva 04 Apr '05

04 Apr '05

Hello, I've been puzzling over something but can't figure out a solution. I have an RSS feed providing the content behind all the links on this page: http://demo.plinkit.org/interestsideas/goodreads/booklists. There's a nice bookmarklet tool in the world called LibraryLookup that lets you check whether a book you find on Amazon or something is in your library's catalog by scraping up the ISBN and launching an ISBN catalog search. It's a javascript, really. I thought I would adapt this to create a little add-on for the stuff the bestsellers RSS brings back to my site. What I need to do is pluck out the ISBNs in the links on a page like this one: http://demo.plinkit.org/interestsideas/goodreads/sinList?synmap=Hardcove rFiction The ISBNs are all in the URLs for the book titles ("isbn=Some10digitNumberHere"). How would I look for a piece of text in that shape, i.e., isbn=5893193390, then, if it's there, copy and paste that piece of information into the LibraryLookup javascript I have. The end result should be that, if there's an ISBN in a feed result, an extra link appears for each entry that says something like "Check the catalog," which you can click to look that book up in your own library's catalog. I've been staring at the template that formats the RSS feed to figure out whether any TAL expression would work for this. I've been playing with a short Python script, then wondering how to call it within that template, but I think I have to use regular expressions to do it. I'm sorry to be so lost on this, but I guess I am. I'd love to do something cool like this for our little Plinkit libraries. Can anyone help? I'll take anything from a broad strategy to actual code snippets (I'm a terrible programmer but a good librarian). Thanks Eva the Librarian

Re: [Zope] Does anyone care whether we deprecate ZClasses?
by Yuri 04 Apr '05

04 Apr '05

Yes, but BEFORE do a tool to convert them in a python product or archetype similar, a tool to change base classes, a tool to convert a zclass based on catagaware to one based on catalogPATHaware, or merge the two. Or you just deprecate something that is used and don't deprecate some code that is obsolete by year ? :)

SESSION invalidate method
by David H 04 Apr '05

04 Apr '05

Hi List, I am curious about the SESSION.invalidate() method. This code sets a SESSION key and value and then calls SESSION.invalidate(): <tal:block define="dummy python:request.SESSION.set('Dodgers','Baseball')" /> before invalidate <tal:block define="dummy python:request.SESSION.invalidate()" /> after invalidate() Produces this output: before invalidate id: 11125588150079827980, token: 95966850A1xaz-gQYlU, contents: [('Dodgers', 'Baseball')] after invalidate() id: 11125588150079827980, token: 95966850A1xaz-gQYlU, contents: [('Dodgers', 'Baseball')] It seems that SESSION.invalidate() does not take immediate effect. Seems like a developer could getinto trouble if the same script *both* does SESSION.invalidate() SESSION.set('something','somevalue'). Because after the script runs 'something' goes away when invalidate() finally occurs. And is the effect described above to be expected or do I have this wrong? Thanks, David
