Issue 1896: manage_changeProperties() vs manage_addProperty()
by Berthold Stöger 23 Jun '06

23 Jun '06

Hello, in Issue #1896 (http://www.zope.org/Collectors/Zope/1896) I describe a difference in the behaviour of manage_changeProperties() and of manage_addProperty(): An array of ints is converted to an array of strings with manage_addProperty(), but not with manage_changeProperties(). You closed the bug with the following comment: > Type converters only deal with the outer type but not with the types of > contained elements. This should be handled on the application level. Well, first of all this isn't true as my script shows (note: the report has a buggy test script, correct one attached): When using manage_addProperty(), the contents of the array *are* converted from integers to strings. Or maybe I'm reading you wrong? Furthermore, this still doesn't explain why the two functions behave differently. Digging a bit deeper, I found out that the culprit is in lib/python/OFS/PropertyManager.py: In manage_addProperty() the type_converter is always called, but in _updateProperty() the type_converter is only called if the value is a string. Similar code can be found in lib/python/OFS/PropertySheets.py Maybe there is some reason for this behaviour, but I can't think of one. Either of the following diffs (of course not both!) fixes the problem for me: --- lib/python/OFS/PropertyManager.py.old 2006-06-18 09:56:13.000000000 +0200 +++ lib/python/OFS/PropertyManager.py 2006-06-18 09:57:01.000000000 +0200 @@ -202,16 +202,13 @@ self._setPropValue(id, value) def _updateProperty(self, id, value): - # Update the value of an existing property.

Basic Authentication SSL Redirector
by Josef Meile 23 Jun '06

23 Jun '06

Hi, After having started the thread about securing CookieCrumbler[1], I figured out that it was better to secure Basic Authentication instead. So, I just created a new Product, called JMSSLBasicAuth[2], which is based on the CookieCrumbler Transversal Hook. Instead of Cookie Authentication, I will redirect insecure Basic Authentication requests to ssl. I have tested it and it seems to work. I'm planning to use it in production websites, so, I would really appreciate if you could give me some constructive feedback about the product (See reference [2]), ie: what can I improve, change, or add? Thanks in advanced Josef [1] SSL Redirect for CookieCrumbler http://mail.zope.org/pipermail/zope/2006-June/166784.html [2] JMSSLBasicAuth - Secure Basic Authentication Redirector http://www.zope.org/Members/jmeile/JMSSLBasicAuth

ANN (Screencast): Installing Zope at WebFaction
by Remi Delon 22 Jun '06

22 Jun '06

Hello everyone, WebFaction (formerly Python-Hosting.com) have just released a screencast demo of their control panel. The 6 minute demo shows how you can setup a Rails, WordPress, Django and TurboGears application in a few clicks, and then "mount" these applications on various domain(s)/URL(s). The one-click installer already supports all major tools, including Rails, WordPress, Djano, TurboGears, Zope, Plone, Trac and Subversion, but also lightweight tools such as static HTML, CGI or PHP. Even though Zope itself is not shown in the demo, it is supported in the one-click installer so its installation works just like the other applications. We already hosts hundreds of Zope and Plone sites. The demo is available at: http://blog.webfaction.com/control-panel-demo Remi. http://www.webfaction.com - Hosting for an agile web PS: WebFaction offers free Trac/Subversion hosting for all open-source python projects. We already host more than 200 of them.

I have an external method that is trying to create a Transient Object Container in a 'temp_folder', as follows: def BuildGarbageCollector(self): folder = self.restrictedTraverse('Coz/TempImages') # Coz/TempImages already exists folder.constructTransientObjectContainer(self, id='GarbageCollector', timeout_mins=10, limit=0, delNotification=BASEFOLDER+'DeleteTempImage') and I get the following error: Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module OFS.DTMLMethod, line 144, in __call__ - <DTMLMethod at /Coz/WUI/tst> - URL: http://192.168.123.2:8080/Coz/WUI/tst/manage_main - Physical Path: /Coz/WUI/tst Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Let, line 75, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: document_id Module <string>, line 1, in <expression> Module Products.ExternalMethod.ExternalMethod, line 232, in __call__ - __traceback_info__: (('tst',), {}, None) Module /apps/zope/Extensions/cozumo.py, line 212, in ProcessControl Module <string>, line 1, in ?

I can manually (thru the ZMI) add a TOC to the TempImages folder, but I can't create one programmatically. Can anyone point me in the right direction?! Thanks, Jonathan

ZWiki with Zope 2.7, OS X Server 10.4.x
by baiewola 22 Jun '06

22 Jun '06

I installed ZWiki by unpacking and putting the folder into my Zope Products directory. I restarted Zope and ZWiki shows up as a valid product. However, when I actually try to add a ZWiki from the "select type to add..." pulldown menu, I get this error: Time 2006/06/22 09:05:41.911 GMT-4 User Name (User Id) Anonymous User (None) Request URL https://myserver.com/zope/manage_addProduct/ZWiki/manage_addwiki Exception Type NotFound Exception Value https://myserver.com/zope/manage_addProduct/ZWiki/manage_addwiki Traceback (innermost last): Module ZPublisher.Publish, line 91, in publish Module ZPublisher.BaseRequest, line 335, in traverse Module ZPublisher.HTTPResponse, line 630, in notFoundError . . . (The rest of the error shows HTML tags and the REQUEST object.) I didn't find anything on zwiki.org about this issue, and I tried Googling with no success. If you have experienced this issue, would you please tell me how you fixed it? Thanks! - B __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

ExternalMethod for exporting un-pickled Office files to the filesystem etc
by michael nt milne 22 Jun '06

22 Jun '06

Hi Just wondering if anyone has written or attempted to write a script which would read through a site built using Zope and write all attached/uploaded files (Word, PDF, Excel) etc to a filesystem location in an un-pickled format. Therefore the files would be usable by their native application and be accessible outside of Zope. The business logic behind this is to be able to create, say once a day at night, a copy of all digital business assets for extra back-up and recovery purposes in case of disaster. Also this would be good for migration purposes if required. If not, how long would it take to create such a script? I could probably source a sponsor for it. I realise that it's best to do this at the application level and at the moment this would be through Plone. I've demoed all the Plone external storage products and also checked out DirectoryStorage but all these store pickled files etc. Thanks -- michael

Need prof. tool for conversion html->pdf
by Tomasz Bielecki 22 Jun '06

22 Jun '06

Greetings to all, my company is searching for a tool capable of producing good quality pdf's from page templates or documents on the fly. This tool should somehow integrate with Zope. It could be Zope/Plone product, python script or even shell script invoked by Zope. It can be commercial (and probably will be). I've searched the net, but found nothing that would met this requirements: * professional css conversion: pdf should look almost exactly like source document, all css properties should be handled * it should omit silently html elements, that are not supported (e.g. flash objects, applets) without crash or error * links should be active (clickable) in pdf * conversion of html forms to pdf forms would be nice to see * conversion from flash objects or java applets to static images (somehow) would be nice to see too * even putting flash objects into pdf was considered (i'm suspecting latest pdf format handles build-in flash, since adobe bought macromedia some time ago) Every help that i can get would be appreciated. --

how improving dtml-in nested?
by mbr 21 Jun '06

21 Jun '06

i have two dtml-in nested .... <dtml-in ZSQLMethod> <tr> <td>&dtml-field1; </td><td>&dtml-field2; </td> <td> <select> <dtml-in AnotherZSQLMethod> <option <dtml-if expr="anotherfield1==field3">selected</dtml-if> value="&dtml-anotherfield1;">&dtml-anotherfield2;</option> </dtml-in> </select> </td> </tr> </dtml-in> .... but they are many calls to AnotherZSQLMethod. So I am trying this <dtml-let RS=AnotherZSQLMethod> <----return results to one variable <dtml-in ZSQLMethod> <tr> <td>&dtml-field1; </td><td>&dtml-field2; </td> <td> <select> <dtml-in RS> <option <dtml-if expr="anotherfield1==field3">selected</dtml-if> value="&dtml-anotherfield1;">&dtml-anotherfield2;</option> </dtml-in> </select> </td> </tr> </dtml-in> </dtml-let> i think this is more quick Check data in memory (variable RS) what a ZSQLMethod. But is real. RS is a result of ZSQL or a instance? ps. Sorry for my english. -- Lo bueno de vivir un dia mas es saber que nos queda un dia menos de vida
