New to Zope and a dumb question
by John Gilger 20 Feb '02

20 Feb '02

I searched the archives, but must not have used the correct search terms because I didn't find the answer :( Can Zope be run on a web-site provided by an ISP like Earthlink or MSN? If so, could someone point me to the "how-to"? TIA John _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.

Using ZSQL Results in python: "dictionaries" property doesn't exist
by Igor Leturia 20 Feb '02

20 Feb '02

Hi all! I am trying to use the "Results" variable returned by any ZSQL method in a python script, as shown in this how-to: http://www.zope.org/Members/spinwing/ZSQL_Results . The thing is I can access Results.names() and Results.data_dictionary() as shown in the examples there, but not Results.dictionaries(). It says that the property doesn't exist. Any ideas?

Re: How can I call a ZSQL method in <dtml-if> tag?
by jlagarde＠bigfoot.com 20 Feb '02

Jean, Figure I should be a contributor to this list once in a while, and that's an easy one... Problem is that CountCrew used in expr="" is a reference to the method, not the result of calling it, so what you really want is CountCrew(), and actually, since ZSQL methods always return sequences, CountCrew()[0]. As for the weird behavior you got: 1) CountCrew will indeed always evaluate to true (it's a function) 2) CountCrew == 1 will always evaluate to false because functions generally do not equal numbers ;-) Cheers, Jean --- In zope@y..., Jin Chen <jchen@n...> wrote: > Hi there, > > I am a newer to zope application.

ER: [Zope] Using ZSQL Results in python: "dictionaries" property doesn't exist
by Igor Leturia 20 Feb '02

20 Feb '02

You're right, Dieter, I'm using ZODBCDA. So now, to solve my problem I need to do do one of these two things: 1) Solve the bug in ZODBCDA, which I don't think I am capable of. Could you or anyone give me some help on it? 2) Use whatever ZODBCDA uses instead of dictionaries (I suppose Results returns the records in some field with another name). Does you or anyone know the name of the field ZODBCDA uses instead of dictionaries? Or is there a way to know the properties or fields of an object in Python? If there is, then I would use it to get the public properties or fields of the Results object and then I could try and see which of them holds the records of the query. Thanks in advance, Igor Leturia > Igor Leturia writes: > > I am trying to use the "Results" variable returned by any ZSQL method > > in a python script, as shown in this how-to: > > http://www.zope.org/Members/spinwing/ZSQL_Results .

Help for duplicate key (?) error
by Zanotti Michele 20 Feb '02

Hi all, Excuse if this is a trivial problem. I have Zope 2.5 on NT 4.0. When I'm working on an object in ZMI and click on the view tab I have a Key error. If I open a new window browser (IE6) I can work regularly, but after some time I have this error again. Thanks to anyone can explain this error to me.

DTML in Product WWW does not bring images
by zope news 20 Feb '02

20 Feb '02

Hello Fellow Zopers, I was wondering if anyone has had any luck with doing the following: When creating your own zope product ( I guess what I mean by this is placing a python class in /lib/python very much like OFS or mxm or the like ) and using DTMLFile( view, globals ), my view.dtml file has images that I wish to use, but I have no idea where to place those images so that zope will find them -- can someone give me a clue, please. Thanks ahead of time for your help, Luis.

Help needed with __bobo_traverse__
by jkinsley 20 Feb '02

20 Feb '02

Greetings, I have a Product, myObject, that is acting as a Site Root (containing a Site Root object). So now http://localhost/myObject/rest/of/path/ is accessable as http://localhost/rest/of/path/ Now then I want to add an optional 'virtual sub-object' in the path so that when http://localhost/refid/rest/of/path/ is called the following will happen. 1. I can extract refid (the virtual sub-object) 2. Do a database lookup with refid 3. Set session data based on lookup results 4. Return a response as if http://localhost/rest/of/path/ were called without the refid segment in the path I have created a __bobo_traverse__ method in myObject and accomplished the first three steps, but I have no idea what to return to complete step four. Any help will be greatly appreciated since I have spent the last eight hours trying to figure this out. Regards, Jarrod Kinsley

nested directories
by Matt Gregory 20 Feb '02

20 Feb '02

If I have a namespace which contains a namespace called images while it's parent also contains a namespace called images how do I make the following section of code access the correct namespace? I know where my obvious problem is, when calling parent_meth from child_meth the parent_meth dtml-with images is returning the child images object which does not contain default.gif inside of it's namespace and therefore gives me an exception. The question is what other options do I have? in namespace like: <parent> |_parent_meth (dtml_method) |_<images> | |_default.gif |_<child> |_child_meth (dtml_method) |_<images> |_example.gif ****in child_meth**** <dtml-let image="'example.gif'"> <dtml-var parent_meth> </dtml-let> <dtml-var parent_meth> ****in parent_meth**** <dtml-if image> <dtml-with images> <dtml-var images[image]> </dtml-with> <dtml-else> <dtml-let image="'default.gif'"> <dtml-with images> <dtml-var images[image]> </dtml-with> </dtml-let> </dtml-if>
