A "PostAuthenticationHook" might help you. In such a hook, you can check whether the current user has a "Manager" role and raise "Unauthorized" when it comes from outside your intranet. Zope does not support "PostAuthenticationHooks" out of the box (I think, at least). But there are two implementations around: one is in the Zope collector, the other is on my Zope page <http://www.dieter.handshake.de/pyprojects/zope> -- Dieter

It's probably not quite that CDATA sections "aren't meant to protect you from everything." They _are_, at least in xml (where everything means "<" and "&"). Chances are that the browser here is getting an HTML file, or at least thinks it is, and HTML does not really know about CDATA sections. I also have sometimes had to break up my string literals to prevent this kind of problem (not with Plone, but in other applications). It's probably better to build the string outside of the document.write(), too. Cheers, Tom P

Installing Zope 2.7.2

Hi, I have compile and install Zope 2.7.2 (on a linux platform).

Zope 2.7.2 breaks Plone 2.0.3 login_form
by Peter Mayne 23 Jul '04

23 Jul '04

I've just installed Zope 2.7.2 and attempted to browse to my Plone 2.0.3 /manage form. Instead of getting the expected page, I get: Error Type RuntimeError Error Message FS Page Template login_form has errors: Compilation failed. <pre>TAL.HTMLTALParser.NestingError: Open tags <html>, <body>, <div>, <script> do not match close tag </a>, at line 63, column 188</pre> Looking inside ./CMFPlone/skins/plone_forms/login_form.pt, this relates to the '<' of the '</a> tag: <script type="text/javascript"> // <![CDATA[ if (cookiesEnabled && !cookiesEnabled()) { document.writeln('<div class="portalMessage"><img src="info.gif">Cookies are not enabled. You can not log in if they are turned off. <a href="enabling_cookies">How to enable cookies</a>.</div>'); } // ]]> </script> One workaround was to comment out this chunk of script. Another one was to revert back to Zope 2.7.1. :-) I have no idea if this is Zope tightening up and rejecting an incorrect Plone template, or an introduced bug in Zope which is rejecting a correct Plone template. Has anyone else seen this, or is it a peculiarity of my site?

RE: [Zope] New-style classes and PluggableBrains
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 23 Jul '04

23 Jul '04

I do beleive new-style classes are not currently supported in Zope 2.7.x, due to issues with ExtensionClass. Zope 2.8 should do away with that issue, allowing you to use new-style classes. This, mind you, might not be applicable to you, as PluggableBrains might not be wrapped by ExtensionClass?? J.F. -----Original Message----- From: zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]On Behalf Of Michael Ekstrand Sent: July 23, 2004 10:42 AM To: zope(a)zope.org Subject: [Zope] New-style classes and PluggableBrains I'm working on developing a PluggableBrains class for some SQL methods in my application in Zope 2.7.1 (running Python 2.3.3 as shipped in the Windows Zope installer), and I've got a couple quick questions. First, if my class inherits from object, does that break anything? It's also inheriting from Acquisition.Implicit and has security information (as an external method creates one and passes it off to protected code in a place or two). Second, if I have some property objects as members, will code accessing them elsewhere behave in a sane and reasonable manner? Will Zope recognize them properly? Most importantly, can I have some or all of the members that the Z SQL Method will be populating defined as properties in the class?

Enable and Use Custom Classes in Zope
by Istvan Albert 23 Jul '04

23 Jul '04

I posted this in the python group but then I thought it would be quite suited to this group too. So here is an opinion on how to enable custom classes in Zope. --------------------- mir nazim wrote: > Seems cool. Please eleborate it a bit. possibly with some examples. It is one of those things that are not well explained in the Zope docs ... adn this post too seems like it should belong to a Zope group. Yet I heard python people say that the Zope model does not allow one to approach a problem in a more rigorous, 'programatic' way. This is only partly true. Here is how one could go about it in what I think is the so called MVC, Model-View-Controller pattern. Let's say that we have a situation where one would need to make use of an instance of a custom User.User class located in a custom package named foo. (Note that I'm typing this in so it might have typos in it.) --- step 0. write and test the foo package and User.User class --- step 1. you need to deploy your package into the zope python. I use distutils: <zope_python> setup.py install the only thing here is that it is easy to forget and use the "other" python ... then you are trying to track probelms that don't actually exists, can be very annoying -- step 2. enable the classes in Zope. Create a folder in the Products directory called <whatever you want> Place the following __init__.py file in this folder: from AccessControl import allow_module, allow_class, allow_type from foo import User allow_module('foo.User') allow_class(User.User) allow_type(type(User)) -- step 3. to use your class here is the hello.py python script that read the user instance from a session. from foo import User hello_zpt = container['hello.zpt'] error_zpt = container['error.zpt'] user = container.REQUEST.SESSION.get(key='user', None) if user: # I can do here whatever I want to with the user instance if user.user_type == 'Troll': msg= 'Go away!' else: msg ='Howdy!' return home_zpt(user=user, msg=msg) else: return error_zpt(msg='Please log in!') --- step 4. in hello.zpt then I have something like this: A message for user <b tal:content="options/user/user_name"/> of type <b tal:content="options/user/user_type"/> : <b tal:content="options/msg"/> --- I believe that The User.User class -> hello.py -> hello.zpt chain forms what is called the MVC (Model-View-Controller) pattern. The model is the class instance itself, the controller is hello.py and the view is in hello.zpt. I found that it takes a lot of discipline to stay outside the zpt files without computing all kinds of intermediate results in them. When making small 'adjustments' it is very tempting to do them by defining some behavior inside the zpt. But then, invariably, after a few days I can't remember anymore how things work... So for me putting everything in the .py controllers is paying off. best, Istvan.
