Problem: Accessing ZClass propertysheet properties
by Roger Lam 17 May '01

17 May '01

I followed an sample from "Chapter 12: Extending Zope" of Zope Book however the following pythonscripts didn't work. ================================================== ## Script (Python) "isHungry" ## """ Returns true if the animal hasn't eaten in over 8 hours """ from DateTime import DateTime if (DateTime().timeTime() - self.last_meal_time.timeTime() > 60 * 60 * 8): return 1 else: return 0 ================================================== The problem: "self" not found! I've tried "container", "context" and other possible mixes and still don't have any clue to get it work. Please help. Thank you. Roger.

But when I want to add a new connection in ZOPE I always get the Error with the Error Type: Attribute error and the Error Value: server_capabilities in db.py. MySQL runs well. What could be the problem?

Users editing properties -- howto?
by Leigh Ann Hildebrand 17 May '01

17 May '01

Some background: I'm using Zope to create and manage an internal document library for engineers and developers. Because of the circumstances, website security isn't an issue; I don't have to require logins for users. I work in dtml only right now -- no python. I have only been doing so for a couple of weeks. I'm not a programmer. (Translation: use small words and don't assume I know how to do basic things yet!) I've been asked to implement a keyword indexing/search feature. Documents are currently represented by dtml documents, with a "keywords" property of the type "tokens". I'm listing the keywords at the top of documents, by referencing <dtml-var keywords>. I'd like for users to be able to use an "Add" feature to add a keyword to a document if they feel one is missing. That would involve an "Add keyword?" link, I guess. The result would be that the keyword property for that document would be modified. Can anyone offer suggestions/examples for doing this? Are there problems with it? (Other than the problems with keyword indexing in general, please.) Is there some more elegant way to handle this, that I, as a non-python person Zope newbie, could handle? Thanks!

Zope log in too slow in local network
by Igor Leturia 17 May '01

17 May '01

Hi! I'm new with Zope, I just downloaded and installed it yesterday. But I've got a problem: I installed Zope in my local network's server, which runs on Windows 2000 server, as a service; when I go to another computer, open the navigator and type http://localhost:8080/manage, I have to wait for more than a minute till it asks my username and password; after that it works fine and very fast, but I think the waiting time at the beginning is not normal and I want to fix that. I think that the problem might be that it starts finding the address in the internet, and when that fails (after a minute) it tries on the local network. How can I fix this? The server with Zope is a Windows 2000 Server, but the computer connected to the internet is a Windows 98 with a gateway installed. Thanks in advance, Igor

RE: [Zope] Getting user permissions
by Randall F. Kern 17 May '01

17 May '01

I do this all over the place in a python product: user = getSecurityManager().getUser() if user.has_permission('Foo', ob) This is of course the same as your sample (if the user is a normal zope user object). So I would look somewhere else for the problem. -Randy > -----Original Message----- > From: Andy McKay [mailto:andym@ActiveState.com] > Sent: Wednesday, May 16, 2001 11:18 AM > To: Steve Drees; zope(a)zope.org > Subject: Re: [Zope] Getting user permissions > > > > SecurityGetUser is the blessed way to get a user object. > > I thought that was just for DTML?

Management interfaces for ZPatterns applications
by Itai Tavor 17 May '01

17 May '01

Hi, I'm struggling with finding the best way to implement a management interface for a ZPatterns-based application. In the past I've implemented a custom interface for every application, but to keep my current project simple, I'd like to take advantage of the existing management interface. Problem is, it's not easy. First, the manageInstances_html methods of my Specialists need to be integrated into the management tabs. But /manage on a Specialist gives me the standard Specialist management tabs, so I would have to create a custom Specialist-subclassed Product for every Specialist, just to add in my own tabs. Second, I can't get the tabs_path to show anything useful. My management links use absolute_url. So if, for example, I'm viewing a Task at /my_site/Tasks/123/manage_edit and I click on a subtask link, I get /my_site/Subtasks/456/manage_edit - so the tabs_path doesn't show the object's context. If I avoid using absolute_url, in the same case I would get /my_site/Tasks/123/Subtasks/456/manage_edit, which is a bit more useful but also ugly and confusing. So, what does this leave me with? Create a Python Product for the top level of the application and for every Specialist that needs to display a UI for the classes it manages. Then, override tabs_path_default with a method that somehow figures out the right path to display. And how would that work? I still think management links should use absolute urls, so I need to somehow build the path back from the displayed object, without relying on the traversal path. I could get every object supply a parent_id, then I would have to scan all the Specialists to find that parent, display it, and go on to locate its parent. KISS goes out the window. Can anyone throw some ideas on how to simplify this mess? I'm starting to think my life would be a lot easier if I didn't use ZPatterns and just used object managers to store contained objects... but I don't want to give up ZPatterns yet...
