Protecting Zope solution / application -> deploying solutions to customers
by Heimo Laukkanen 27 Dec '02

27 Dec '02

Is there a way to protect your intellectual property, if you deliver Zope solutions to customers who have Zope instance running or you will also deploy Zope there. I'm talking about solutions that cosist mostly of some Python based products, Python scripts and page templates -> ie. typical web based site that has some logic, functionality and content, which is accessible through the TTW interface. And even though the client would not have admin account to the Zope instance, they could write a new superuser with zpasswd.py and then get access to everything. My question now is, is there a way to protect your work from being copied, altered or even read in source format? -huima

privileges problem
by Catonano 24 Dec '02

24 Dec '02

Hello all, I'm tring to execute this script: lista = [] folder = container.indice2() #indice2 is a ZCatalog for file in folder: if not file.hasProperty('codice'): lista.append(file.id) attributes=getattr(folder, file) attributes.manage_addProperty('codice', 'inserted yet', 'string') return lista I borrowed the idea from the /Examples/GuestBook/addEntry script Zope prompts me for a user name and passwd, I type my usual account data (I'm the only user and I think I have full privileges) and BAM! Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access in this context Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page. If the error persists please contact the site maintainer. Thank you for your patience. I tried to give the script all the proxy roles I could I opened Control Panel/acl_users and gave manage property permission to managers and owners (I'm a manager user): NOTHING! Please: what's going on? Thanks anybody who will help me Bye Catonano

standard_error_message in Python Product
by Thomas Guettler 13 Dec '02

13 Dec '02

Hi! Is it possible to write a standard_error_message as a method in a python product? "def standard_error_message(self, **kwargs)" --> this does not work. I get: An Error occured while displaying the error message ... I don't get it working, according to the collector it should be working with 2.6.0 Version: (Zope 2.6.0 (source release, python 2.1, linux2), python 2.1.3, linux2) thomas -- Thomas Guettler <guettli(a)thomas-guettler.de> http://www.thomas-guettler.de

DTMLFile
by Steffen Hausmann 13 Dec '02

Hi, I am working on an external method with a form and a button on it. <input type="submit" name="manage_addTerminhinweis:method" /> The method called by the button is defined in my class like this. manage_addTerminhinweis=DTMLFile("dtml/manage_addTerminhinweis", globals()) The manage_addTerminhinweis file doesn't use any dtml expressions. If I press the button as admin (inituser) everything works fine, but if I login as a normal user (defined in an acl_user folder) who has the same rights as admin I'm getting an unauthorized error. Any ideas why this doesn't work. MfG Steffen -- Manche Maenner bemuehen sich ein ganzes Leben lang, das Wesen einer Frau zu verstehen.

Re: Zope Couldn't install ZCatalog - or OFSP

I had the same error message, but finally I could solve it or that's why I think. I will do the final test with my real server this weekend. According to those two messages: http://groups.yahoo.com/group/zope/message/102321 http://groups.yahoo.com/group/zope/message/102714 There is a problem when you have ZClases that are subclasses of ObjectManager because something changed in the new Zope. I tried what they said there and convined it with some steps more: 1- Be sure of having a copy of your Zope in another place, just in case this fails. 2- From the ZClasses that are based on ObjectManager, delete the suboject references in the "Subobjects Tab" and save changes. 3- Export them. 4- Import them in your new installation and then add the subobject references. 5- From your old zope export your other ZClasses and import them in your new installation. 6- Install the other products that you are using. 7- Export all your old Zope site and reimport it in a new installation. I know it's a really boring and long procedure, but at least it seems to work. Regards, Josef.

How to access Zope root in Script (Python)
by Jon Whitener 08 Dec '02

08 Dec '02

How do I refer to the root Zope directory within a Python script? For example, to access the "price" object in a Page Template, (when price in a sibling or parent folder) I just say "root/service/price", but a Py script doesn't recognize "root", so what do I use? Thanks in advance, Jon Detroit, Michigan USA

context in a Product's python code (not Python Script)
by John K. Hohm 05 Dec '02

05 Dec '02

I have a Page Template and Python Script that are working fairly well together to generate a navigational menu on my site, and now I want to make them part of a product. I have tried this: class CMS(Folder): # ... # old "menu" Page Template copied to www/menu.zpt file security.declareProtected('View', 'menu') menu = PageTemplateFile('www/menu', globals()) menu._owner = None security.declareProtected('View', 'menu_items') def menu_items(self, levels=2, REQUEST=None): context = self._getContext # body of old "menu_items" Python Script copied here def _getContext(self): while 1: self = self.aq_parent if not getattr(self, '_is_wrapperish', None): return self I cannot seem to find the way to get the bindings a Python Script has, particularly the context binding. As you can see, I tried grabbing the _getContext method from Script, but it gives me the root Zope object, instead of the object that is being requested and having menu called on it from the web. What am I doing wrong?

folder name problem
by Ben Avery 03 Dec '02

03 Dec '02

Hi, using Zope 2.6.0 with Python 2.1.3 on Solaris 7, I come across the following strangeness: I have a folder called 'hq'. Inside this I want to add another folder called 'manage'. there is nothing inside hq called anything like manage. When I try to add the folder, I am told that this is a bad request, because the id 'manage' is already in use. It clearly isn't in use in this folder. Is this some kind of reserved word in Zope? thanks Ben Avery YouthNet UK

MessageDialog in Python Script
by Elena Schulz 03 Dec '02

Hi, is there a possibility to return a message while executing without to interupt the Script or redirect to another one (because of variable-transfer)? As message from Globals.MessageDialog is unauthorized in Python Scripts. -- many thanks for your replies, Elena
