I found it... This will interest anyone trying to make it run under Windows 2000: You might need to put msvcr71.dll in your \WINNT\SYSTEM32 directory because extensions probably were built using Visual Studio .NET 2003 and they look for that file that contains some necessary libraries (msvcr71.dll is simply the Visual C++ runtime library) So, put the extensions at the Python directory and everything works... You can find that file, for example at: http://justkez.com/pistos/hydrairc/msvcr71.dll -----Mensaje original----- De: Andreas Jung [mailto:andreas@andreas-jung.com] Enviado el: domingo, 10 de agosto de 2003 14:21 Para: Juan Manuel Ruiz Garcia Asunto: Re: [Zope] TextIndexNG No idea, i am not running Zope on WinXX. -aj --On Sonntag, 10.

I would like to install Zope on a linux server. I will need the following minimum... Python 2.2 Zope 2.7 or greater? Which Linux should be the one i should use... if assuming, that Red hat 9 has problems with zope by default. Does plone work with Zope 2.7 ? Kind Regards, Andy.

Syntax for dtml-in property check?
by Dan Shafer 15 Aug '03

15 Aug '03

I'm tripping over what seems like should be fairly straight-forward syntax. Hopefully someone here can point out what I'm overlooking. Situation: I have a folder that contains a bunch of folders, each of which has a property named "coach_id" that I've created and updated programmatically. Task: I have one user who is allowed to see the contents of all folders. All other users are restricted to folders where they are the Coach (i.e., where their AUTHENTICATED_USER== the coach_id of a particular folder). Approach: I have a DTML method that loops over all the folders and displays a list of folder links for each folder the user is authorized to see. That method works fine when I don't try to limit it by authenticated user name. I use a simple <dtml-in> construct for this purpose: <dtml-in expr="objectValues('Folder')" sort=title_or_id> I placed a <dtml-if> statement inside the <dtml-in> construct. That is where the problem is popping up. My if statement should look like this, I think: <dtml-if expr="(AUTHENTICATED_USER.getUserName() == 'Magic User') | (AUTHENTICATED_USER.getUserName() == sequence-var-coach_id)"> But I get an error from Zope indicating the public variable "sequence" isn't defined? I'm in a <dtml-in> so I *believe* sequence should have meaning. Am I wrong? I tried this with only one logic clause in case the problem was the OR syntax or logic. But this: <dtml-if expr="AUTHENTICATED_USER.getUserName() == sequence-item.coach_id"> produces the same "global variable sequence not defined" error. If i hard-code a name into that same sequence, the operation works but, of course, does not filter on the coach_id. <dtml-if expr="AUTHENTICATED_USER.getUserName() == 'Magic User'"> It seems evident that I'm missing something about how <dtml-in> works. I have believed that in the midst of a <dtml-in> I'm iterating over a sequence that is represented by the built-in Zope variable, "sequence." Evidently I'm wrong. Can anyone help? I feel like I'm just guessing at random possibilities now. Obviously time to raise a white flag. (I have to say, this happens so often with Zope that I often wonder if I'm just too dense to get good at this. I try to read and follow docs, but things just always end up slightly out of phase for me.)

Syntax Issue with dtml-in iteration

Except 1) the other measures protect against thru-the-web access, but not from local access. Anyone who can read data.fs can see the user passwords, which the standard UserFolder stores without encryption by default, and then can log in as Manager and change anything. And anyone with write permission to the filesystem can create an emergency user, log in as such, and modify all objects inside Zope (the emergency user can do almost anything without restrictions, just can't create new objects). Zope may have a good shield from web attacks but I think it is very vulnerable for local intrusion or sabotage. Gabriel Genellina Softlab SRL

accessing attributes of a referenced object via ZPT
by Derrick 'dman' Hudson 14 Aug '03

14 Aug '03

I am trying to make a nice display of some objects using ZPT. These objects refer (by storing the path as a string) to other objects and I want to display an attribute of the referred-to object in the display. What is the best design to achieve this? The following ZPT code works, but I highly doubt it is the best design :-) <td tal:content="python:here.restrictedTraverse(employee.department).title" /> Would it be best to write a python script that iterates over the actual objects creating a "mirror" object for each that contains the attributes to be displayed (without the intermediate references) and let the ZPT handle only the mirror objects? TIA, -D -- If we claim to be without sin, we deceive ourselves and the truth is not in us. I John 1:8 http://dman13.dyndns.org/~dman/

How to enhance verbosity of answers of incorrectly filled forms
by Andreas Tille 14 Aug '03

14 Aug '03

Hi, is there any clever way to give the user a more verbose answer - preferably in an apropriate layout if I use <form action="report.html" method="get"> <input name="Id:int:required"> <input name="Text:string:required"> </form> instead just Empty entry when integer expected Well I know I could change the layout a little bit by changing the default error method but I would like to give the user a hint *which* field(s) has to be filled. I could do this with a Python script but I'm currently trying to test the power of PageTemplates and ZSQL methods instead of my former way to use Zope with more or less sticking to Python Scripts exclusively. Kind regards Andreas.
