How to import a basic class in Script (Python)
by Tudor Gabriel 19 Jul '07

19 Jul '07

To learn zope I am trying to write a basic library page. I wrote a book_py class ... and from search_books_py try to return a list of books to show in a ZPT. now let's suppose all the files (all the py and zpt files) are in the same directory:Library in search_books_py i tried importing the book class in this ways: from book_py import * from Library.book_py import * from here.book_py import * from container.book_py import * they all give ... an unauthorized access to book_py when importing. i even renamed book_py to book.py and tried all the above imports like from book import * ... same error. I've searched Zope Help and it mentions in there that i have to make a new dir in Products called whatever and add to __init__.py the allowimport or something like that, for my package. i tried that too ... same error (haven't restarted zope after... should i?) . >From Zope Help i get that only some standard python modules can be imported this way ... So is there a way to simply make a class in a Script(Python) and import it in another Script(Python). If there isn't, and i have to make a custom Product for my Book class... please give me a basic example of how can i make that. Thank you for your patience.

z3c.form 1.5.0 and z3c.formdemo 1.3.0 released!
by Stephan Richter 19 Jul '07

19 Jul '07

Hello everyone, I am pleased to announce new releases for z3c.form and z3c.formdemo. The latest changes were mainly driven by Paul Carduner's work on z3c.formjs and z3c.formjsdemo, but also by continued customer work. Again for the curious and impatient ... --------------------------------------- This time there is no new demo available, but the old ones still work as expected. To run the demos do the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/trunk formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v $ ./bin/demo fg Now you can access the demo under: http://localhost:8080/ We now also have functional tests that check all the demos: $ ./bin/test -vp1 On the Javascript Front ----------------------- A lot more progress has been made on this front. Look out for Paul's announcement! It will make up for the missing new demo in formdemo! Changes ------- z3c.form ~~~~~~~~ - Feature: Added a span around values for widgets in display mode. This allows for easier identification widget values in display mode. - Feature: Added the concept of widget events and implemented a particular "after widget update" event that is called right after a widget is updated. - Feature: Restructured the approach to customize button actions, by requiring the adapter to provide a new interface ``IButtonAction``. Also, an adapter is now provided by default, still allowing cusotmization using the usual methods though. - Feature: Added button widget. While it is not very useful without Javascript, it still belongs into this package for completion. - Feature: All ``IFieldWidget`` instances that are also HTML element widgets now declare an additional CSS class of the form "<fieldtype.lower()>-field". - Feature: Added ``addClass()`` method to HTML element widgets, so that adding a new CSS class is simpler. - Feature: Renamed "css" attribute of the widget to "klass", because the class of an HTML element is a classification, not a CSS marker. - Feature: Reviewed all widget attributes. Added all available HTML attributes to the widgets. - Documentation: Removed mentioning of widget's "hint" attribute, since it does not exist. - Optimization: The terms for a sequence widget were looked up multiple times among different components. The widget is now the canonical source for the terms and other components, such as the converter uses them. This avoids looking up the terms multiple times, which can be an expensive process for some applications. - Bug/Feature: Correctly create labels for radio button choices. - Bug: Buttons did not honor the name given by the schema, if created within one, because we were too anxious to give buttons a name. Now name assignment is delayed until the button is added to the button manager. - Bug: Button actions were never updated in the actions manager. - Bug: Added tests for textarea widget. z3c.formdemo ~~~~~~~~~~~~ - Feature: Created functional tests for the demos. - Feature: Moved all application ZCML declarations into a ZCML file called ``application.zcml``. Enjoy! Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training

I'm troubleshooting a complex shop I had a programmer who worked for me build...so it's not my code...and it's complex ;) I went into the shopkeeper's side and was able to successfully query the database. I was, for example, able to display the "cotton" products for editing. However, when I do essentially_the_same_thing TTW with the following code snippet, it hangs! <tal:block metal:define-macro="content" ?????????? define="dummy python:request.set('category', 5)"> ? <tal:block metal:use-macro="here/Store/Main_frame_content/macros/content" /> </tal:block> Furthermore, mytop shows the user is hanging: ???? 30 mysqluser?????? localhost mrtableclo?????? 473? Sleep What should I do next to troubleshoot this? TIA, Tony ________________________________________________________________________ AOL now offers free email to everyone.

does zope support java script
by Josef Meile 18 Jul '07

18 Jul '07

> I figured out that the small browser inside ZMI has a problem with > javascripts, it can't display them. But, when I visit the URL of the page > from IE, the javascripts are executed normally. Now I understand why this fails. You are pressing the View/Test tab inside the ZMI. For some objects, zope will add an extra text at the end of the url. ie: for images it will add: /your_image.gif/view_image_or_file, for scripts, page templates, and other objects, it will add /your_object/ZScriptHTML_tryForm. For other objects no extra text will be added, so they will work as expected. (Look at the status bar of your browser before hitting this tab). >Am I right that ZMI can't displays JS ? and is there a solution for it. If I'm right, this is a path problem, one could solve it, but I think the invested time isn't worth. You'd better copy and paste the link from the View/Test tab and remove the extra text at the end.

UnicodeDecodeError in Zope 2.10.4 (upgrade from 2.8.4)
by Maciej Wisniowski 17 Jul '07

17 Jul '07

I've upgraded my installation from Zope2.8.4 to Zope 2.10.4 (by copying data.fs, Products/ etc.). I have publisher encoding and management_page_charset set to utf-8. Also system default encoding is utf-8. Zope 2.10 is said to have better Unicode support with UnicodeEncodeConflictResolver. It is but unfortunatelly in some cases this is not enough. Seems that code that is 'protected' by Resolver is not the only code that may be affected by non unicode strings. Simple example is with 'structure' keyword. eg: This works (resolver resolves conflict): <em tal:content="python: 'żółć'">template id</em>. This doesn't work: <em tal:content="structure python: 'żółć'">template id</em>. Also if you have Folder instance and set it's Title to the string that contains some i18n characters you're not able to even add page template inside it. Error traceback in both cases is same: Error Type: UnicodeDecodeError Error Value: 'ascii' codec can't decode byte 0xc5 in position 200: ordinal not in range(128) Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module Products.PageTemplates.PageTemplateFile, line 129, in _exec Module Products.PageTemplates.PageTemplate, line 89, in pt_render Module zope.pagetemplate.pagetemplate, line 117, in pt_render Module zope.tal.talinterpreter, line 271, in __call__ Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 534, in do_optTag_tal Module zope.tal.talinterpreter, line 516, in no_tag Module zope.tal.talinterpreter, line 346, in interpret Module zope.tal.talinterpreter, line 754, in do_insertStructure_tal UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 200: ordinal not in range(128) problem is with: text = unicode(structure) at Module zope.tal.talinterpreter, line 754, in do_insertStructure_tal sitecustomize.py with setdefaultencoding('utf-8') solves this but it is not nice solution. I wonder whether this should be submitted as a bug, or maybe there is different solution that I've missed? For the record: one more thing that was wrong for me during migration was 'expand' attribute of ZPT that in case of few ZPT objects was set to true in 2.10.4 while oryginally in 2.8.4 it was false. This caused that tales expressions disappeared from ZPTs under 2.10.4. I've written a script that explicitly set expand=0 to all ZPT instances in Zope 2.8.4 and then, after migration, everything is OK. -- Maciej Wisniowski

by Rogerio Atem de Carvalho 15 Jul '07

15 Jul '07

The Zope based ERP project ERP5 has on chapter on the O'Reilly book Beautiful Code: Leading Programmers Explain How They Think http://www.amazon.com/Beautiful-Code-Leading-Programmers-Explain/dp/0596510… The book features well known authors such as Brian Kernighan, Jon Bentley, Charles Petzold, Douglas Crockford, Andrew Kuchling, and Yukihiro Matsumoto, among many others. Also, it has some not-known authors, like me. On this chapter we explain the basic ERP5 architecture and how Nexedi SARL (France) has managed to create a highly flexible framework for Enterprise Information Systems on top of Zope. If someone is interested in this particular chapter, please send an email to me. Bye for now, -- Prof. Rogério Atem de Carvalho, D.Sc.

htmldoc problem
by Garry Saddington 15 Jul '07

15 Jul '07

I am using the following external method to write pdf files. import subprocess def html2pdf(self,source): f=open('/opt/scholarpack/ancillary/pdf.html','w') f.write(source) f.close p=subprocess.Popen(['htmldoc', '--webpage', '/opt/scholarpack/ancillary/pdf.html','-f', '/opt/scholarpack/ancillary/mypdf.pdf']) p.wait() When I do this the html is truncated and an incomplete pdf is generated. However, if I rum htmldoc in a terminal on the same html file then the ouput is perfect. Can anyone see where the external method may be going wrong, apart from the formatting that kmail is enforcing on this code snippet!? Regards Garry
