New set of z3c.form* releases!
by Stephan Richter 24 Aug '07

24 Aug '07

Hi everyone, in the past month more project-related work, user feedback/requests and Javascript work has driven the development of the z3c.form framework. There are many new exciting features. There were also some small refactoring changes, which might require your CSS and tests to be adjusted. Please read the changes section below carefully! As always, the demos can be run using: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.4.0 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -N $ ./bin/demo fg Thanks to Roger, Windows users should be able to run the demos this way now as well! Visually, not much has happened; there are no new demos. However, just wait until the next round of z3c.formjs* releases! Changes ------- - Feature: An event handler for ``ActionErrorOccurred`` events is registered to merge the action error into the form's error collectors, such as ``form.widgets.errors`` and ``form.widgets['name'].error`` (if applicable). It also sets the status of the form. (Thanks to Herman Himmelbauer, who requested the feature, for providing use cases.) - Feature: Action can now raise ``ActionExecutionError`` exceptions that will be handled by the framework. These errors wrap the original error. If an error is specific to a widget, then the widget name is passed to a special ``WidgetActionExecutionError`` error. (Thanks to Herman Himmelbauer, who requested the feature, for providing use cases.) - Feature: After an action handler has been executed, an action executed event is sent to the system. If the execution was successful, the event is ``ActionSuccessfull`` event is sent. If an action execution error was raised, the ``ActionErrorOccurred`` event is raised. (Thanks to Herman Himmelbauer, who requested the feature, for providing use cases.) - Feature: The ``applyChanges()`` function now returns a dictionary of changes (grouped by interface) instead of a boolean. This allows us to generate a more detailed object-modified event. If no changes are applied, an empty dictionary is returned. The new behavior is compatible with the old one, so no changes to your code are required. (Thanks to Darryl Cousins for the request and implementation.) - Feature: A new ``InvalidErrorViewSnippet`` class provides an error view snippet for ``zope.interface.Invalid`` exceptions, which are frequently used for invariants. - Feature: When a widget is required, HTML-based widgets now declare a "required" class. - Feature: The validation data wrapper now knows about the context of the validation, which provides a hook for invariants to access the environment. - Feature: The BoolTerms term tokens are now cosntants and stay the same, even if the label has changed. The choice for the token is "true" and "false". By default it used to be "yes" and "no", so you probably have to change some unit tests. Functional tests are still okay, because you select by term title. - Feature: BoolTerms now expose the labels for the true and false values to the class. This makes it a matter of doing trivial sub-classing to change the labels for boolean terms. - Feature: Exposed several attributes of the widget manager to the form for convenience. The attributes are: mode, ignoreContext, ignoreRequest, ignoreReadonly. - Feature: Provide more user-friendly error messages for number formatting. - Refactoring: The widget specific class name was in camel-case. A converntion that later developed uses always dash-based naming of HTML/CSS related variables. So for example, the class name "textWidget" is now "text-widget". This change will most likely require some changes to your CSS declarations! - Documentation: The text of ``field.txt`` has been reviewed linguistically. - Documentation: While reviewing the ``form.txt`` with some people, several unclear and incomplete statements were discovered and fixed. - Bug (IE): In Internet Explorer, when a label for a radio input field is only placed around the text describing the choice, then only the text is surrounded by a dashed box. IE users reported this to be confusing, thus we now place the label around the text and the input element so that both are surrounded by the dashed border. In Firefox and KHTML (Safari) only the radio button is surrounded all the time. - Bug: When extracting and validating data in the widget manager, invariant errors were not converted to error view snippets. - Bug: When error view snippets were not widget-specific -- in other words, the ``widget`` attribute was ``None`` -- rendering the template would fail. Enjoy!

TransactionMailHost 0.1.1 released
by Andreas Jung 18 Aug '07

18 Aug '07

I am pleased to announce the first release of TransactionalMailHost. TransactionalMailHost can be downloaded from <ftp://ftp.zopyx.com/open-source/TransactionalMailHost/TransactionMailHost-0…> What is TransactionalMailHost ============================= TransactionalMailHost is yet another MailHost implementation. It integrates with the transaction system of Zope in order to send out email only in case of a committed transaction. TMH currently supports standard SMTP and SMTP AUTH. Requirements ============ - Zope 2.9+ - zope.sendmail Installation ============ - Unpack the archive in your *Products* directory - restart Zope - create a new **TransactionMailHost** instance through the ZMI - configure your SMTP host, port within the ZMI. username and password are optional for SMTP AUTH Note ==== TransactionMailHost is not fully (yet) API compatible with the Zope MailHost implementation. It provides only one public method right now: send(message, fromaddr, toaddrs, subject, encode) The 'subject' and 'encode' parameters are unused right now How does it compare to MailDropHost =================================== MDH decouples the process of sending mail from its delivery. Like all other MailHost implementations TransactionalMailHost blocks the current Zope thread until the end of delivery. This can be a big disadvantage when you send out email to multiple addresses. If you run a site producing lots of email you might better checkout MailDropHost. Author ====== TransactionalMailHost was written by Andreas Jung for ZOPYX Ltd. & Co. KG, Tuebingen, Germany. License ======= TransactionalMailHost is licensed under the Zope Public License 2.1. See LICENSE.txt. Cheers, Andreas -- ZOPYX Ltd. & Co. KG - Charlottenstr. 37/1 - 72070 Tübingen - Germany Web: www.zopyx.com - Email: info(a)zopyx.com - Phone +49 - 7071 - 793376 Registergericht: Amtsgericht Stuttgart, Handelsregister A 381535 Geschäftsführer/Gesellschafter: ZOPYX Limited, Birmingham, UK ------------------------------------------------------------------------ E-Publishing, Python, Zope & Plone development, Consulting

Zope 3 Foliage Sprint
by Stephan Richter 16 Aug '07

16 Aug '07

Hi everyone, it has been over a year, since we had a conference-independent fully Zope 3 focused sprint. And I think it is time to have one! :-) Thanks to JSA Tech, there will be a sprint between September 24-28, 2007 right in the center of historical Concord, Massachusetts. We have reserved a big room where we can easily fit 35 people. For details, go to the link below: http://wiki.zope.org/zope3/FoliageSprint Now that some fairly large Zope 3 projects are in production, this will be a great opportunity to share our experiences, to learn from each other and discuss new directions that we would like to go. Upon request, I will also give some of my Zope 3 training sessions during the sprint. So I envision the sprint to be interesting for any level of Zope 3 developer, from the beginner to the expert. So sign up now! Just add yourself to the list of participants in the Wiki or send me an E-mail, if you can't. Regards, Stephan

ZcxOracleDA 0.5 released
by Andy Hird 06 Aug '07

06 Aug '07

I'm pleased to announce the first release of ZcxOracleDA - a Zope database adaptor for Oracle using the cx_Oracle library. This is an initial development release and should be used with caution! You can download it from: http://www.zope.org/Members/andyhird/ZcxOracleDA >From the README.txt: Z cxOracle DA This is a Zope Database Adaptor for cx_Oracle. It's currently only been tested with Zope 2.7 and above with cx_Oracle 4.3.1 and above. Installation You must install cx_Oracle before attempting to use this DA. You can find cx_Oracle at:: http://cx-oracle.sourceforge.net/ Then extract this product into your Zope instances Products directory. Connection Strings The connection string is passed directly to cx_Oracle.connect(). The string is usually of the form username/password@TNS Known Issues cx_Oracle returns date types as python datetime.datetime types. The DA will check the queries description to see if any of the rows being returned are of that type and if they are will convert them on the fly to Zopes DateTime type. Unfortunately this currently means the DA iterates through all the rows returned and modifies the return values which is far from optimal. Also the DA currently doesn't handle returned datetime timezones well. It currently converts all datetimes to UTC regardless of the timezone Oracle is using. Ideally the DA would query the current Oracle DBTIMEZONE and use that instead. If you want to change the timezone used for datetime conversion then edit db.py and modify CONVERSION_TIMEZONE.
