Object adding strangeness
by Geoffrey L. Wright 14 Dec '00

So I've created a simple little product to dynamically manage CSS. It consists of three ZClasses and the arrangement looks something like this: STYLEn_containerClass \ \--> STYLEn_styleClass \ \--> STYLEn_stylePropertyClass The STYLEn_containerClass can contain a variable number of styles which can, in turn, contain a variable number of properties. I've also hacked the add method for the STYLEn_containerClass so that it creates a number of default styles. So far, this has all worked swimmingly, but I have run into one really strange issue that I can't figure out for the life of me. Basicly, the folder that contains the STYLEn_containerClass somehow(?) manages to aquire the title of the last instance of STYLEn_styleClass that gets created. So in the follow example, the title of the containing folder get renamed to "Header style" from whatever it happened to be before. Does anybody have an idea of why this might be happening? TIA for any answers or leads. My code is below: --- <dtml-comment>Create the "STYLEn" container.</dtml-comment> <dtml-with "STYLEn_containerClass.createInObjectManager('STYLEn',REQUEST)"> <dtml-call "propertysheets.STYLEn_containerClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> <dtml-comment>Create header style</dtml-comment> <dtml-call "REQUEST.set('ts', ZopeTime())"> <dtml-call "REQUEST.set('id',_.str(_.int(ts)) + '-1')"> <dtml-call "REQUEST.set('title','Header style')"> <dtml-with "STYLEn_styleClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "REQUEST.set('element','h1')"> <dtml-call "REQUEST.set('style','header')"> <dtml-call "propertysheets.STYLEn_styleClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-family', REQUEST)"> <dtml-call "REQUEST.set('value','arial, sans-serif')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-size', REQUEST)"> <dtml-call "REQUEST.set('value','16pt')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-style', REQUEST)"> <dtml-call "REQUEST.set('value','normal')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-weight', REQUEST)"> <dtml-call "REQUEST.set('value','bold')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('color', REQUEST)"> <dtml-call "REQUEST.set('value','#000000')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> </dtml-with> </dtml-with> <dtml-comment> Now we need to return something. We do this via a redirect so that the URL is correct. Unfortunately, the way we do this depends on whether we live in a product or in a class. If we live in a product, we need to use DestinationURL to decide where to go. If we live in a class, DestinationURL won't be available, so we use URL2. </dtml-comment> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect(DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect(URL2+'/manage_workspace')"> </dtml-if> </body></html> --- -- Geoffrey L.

In the SQL statement it does'nt show any error msg. And what you have been suggested to me:- *//making a ZSQL Method that issues a really simple query, like: SELECT * FROM InsertYourTableNameHere try this simple test from your "Z MySQL Database Connection" object. Just browse to that object in the Zope management interface, click the "Test" tab and then enter the SQL statement. Then click the "Submit Query" button to test it. When i clicked the "Submit Query" button the illegal operation error msg will come out. In MySQL is no sense of the error msg. This is a bit tricky problem that i dont understand. TQ

stupid file upload question
by Joh Johannsen 14 Dec '00

14 Dec '00

OK, there is a How-To on that, which is helpful, by benno But it says: "In you python external method you can now reference REQUEST.form['attached_file'] as a normal file. You can perform things such as read() on the object. " Now in my Python external method, I can reference things like: REQUEST.form['attached_file'].filename and that is fine. But what is the syntax for actually reading the file? From the above quote I thought it was as simple as x=REQUEST.form['attached_file'].read() but that doesn't work... Either that or some way to get at the name of the file on the server. The above 'filename' is just giving me the name of the file on the client side, I have no idea where it is on the server. Thanks, JJ

Lost with navigation using objectValues

I just try to automatically get a list of subfolders, following the example in the ZopeBook <http://www.zope.org/Members/michel/ZB/SimpleExamples.html>. Here is my code, in a DTML method in the root folder: <ul> <dtml-in expr="objectValues('Folder')"> <li><a href="<dtml-var absolute_url>"> <dtml-var title_or_id></a></li> </dtml-in> </ul> If I call it from /index_html, it works fine. If I call it from any other document anywhere, I just get <ul></ul> (so I'm sure the method has been called) but nothing else as if objectValues sent nothing (no need to say that I *have* subfolders an I also tried without the 'Folder' restriction, with the same result). Any advice? Zope RPM 2.2.2 on RedHat 6.2. Zope version: Zope 2.2.2 (source release, python 1.5.2, linux2) Python version: 1.5.2 (#1, Feb 1 2000, 16:32:16) [GCC egcs-2.91.66 19990314/Linux (egcs- System Platform: linux-i386 Process ID: 17906 (4101) Running for: 2 hours 55 min 45 sec

Re: [Zope] Problems with adding tutorial

After much playing around I determined that the problem was Python 2.0. I downgraded zope to 2.2.4 and still had the identical problem with python 2.0. Then when I downgraded python to 1.5.2 the problem finally went away.

This is a Python feature: If both arguments are integers, the division is performed as an integer division. Use "3.0/2" or "3/2.0" or "float(3)/2" to get a floating point division. Dieter

do you see more than one page name in your url path - eg FrontPage/FrontPage ? are you acquiring a different standard_wiki_header from somewhere ? are you failing to acquire it ? (does page source include "" ?) are permissions ok ?
