I've been in this situation a couple of times before, and have not pursued the "allow_modules()" option because it was simple enough to create an external method. However, this "seemed" like a nice simple case where allow_modules() "should" work, so I wanted to get to the bottom of it and understand my previous problems. >From what you say, the most useful comment I could add to the wiki would be to quote your original response that "allow_module() does not work with all and everything" and add my own conclusion that if allow_module() does not work in a given case it is not worth spending much troubleshooting time on. I'm happy to accept your advice that allow_modules() simply won't work in all cases - but that's the advice I wish I'd found in the wiki 24 hours ago... -- Cheers, Philip

Thanks for the reply. The use case is that my client wants to block a range of IP addresses from being able to view their site. So I need to access the originating IP address and filter appropriately. I've written a few custom zope products before, but I've not done anything that really modifies zope's behaviour on every request - just on requests for the specific objects I'm publishing. So I'm familiar with the request object, but I don't know how to intercept *every* request. Are there any global request life-cycle hooks? If you can point me to those that would be a great help. Cheers, David

Hi All, Sorry Andreas - I hit "reply" instead of "reply-all", and sent my response only to you. Thanks for your reply.

IOW, how could I tell the difference between a module not being a candidate for allow_module() and an error in my own code? I understand that an external method or a product are my other choices, but I'm really uncomfortable about not understanding how I can tell when I can and when I cannot use allow_module() - at the moment, this feels horribly like "trial and error" coding! Enough people have struggled with this that I'd like to understand it well enough to add something to the wiki for the next person who has the problem... -- Cheers, Philip

Our host uses nginx, not apache. We can still do this w/ nginx configuration, but it means maintaining a configuration file rather than application code (which in my experience is more flexible/maintainable). Right now I'm just exploring options, so I'd still like to know how I can do this with Zope. Thanks, David > > -aj > >

The CMF developer community is hereby announcing the release of CMF version 2.1.1. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit http://www.zope.org/Products/CMF/CMF-2.1.1. Roadmap and release information can be found at http://www.zope.org/Products/CMF/docs/roadmap. The CMF mailing list can be reached at the zope-cmf(a)zope.org address, to sign up please visit http://mail.zope.org/mailman/listinfo/zope-cmf . Please file bug reports, feature requests or suggestions in the CMF bug collector at https://bugs.launchpad.net/zope-cmf/ . What has changed since the last release? Bug Fixes - CMFDefault.PropertiesTool: Fix a faulty manage_changeProperties invocation which broke the 'Reconfigure Portal' screen (https://bugs.launchpad.net/zope-cmf/+bug/174246) - CMFCore.exportimport.content: Add simple guard against import failures when the ".objects" file contains empty lines.

Defining a Variable
by Victor Subervi 05 Jan '08

05 Jan '08

Hi; I have this in a page template: <html> <body> <table> <tr> <td tal:define="num python:here.scripts.getQuote"> <span metal:use-macro="here/en-us/quotes/?num/macros/quote" /><br /> <div align="center"> <span class="text"> <a href="quotes.pt" target="_top"><b>The quotes</b></a> </span> </div> </td> </tr> </table> </body> <html> Now, I thought that was the correct way to call the variable "num" (that is, with the question mark: "?num"). Apparently, I'm mistaken. I've even tried defining it this way: <td tal:define="num python:str(11)"> to make sure that num was properly assigned. What am I missing? Also, if I have a dir called "scripts" in which "getQuote" exists, and "scirpts" is in the path, shouldn't that notation work okay? TIA, Victor

Best Practice for including Javascript in Zope Applications
by Matt Hollingsworth 04 Jan '08

04 Jan '08

Hello, I'm new to developing for zope, and I have a quick question regarding some best practices when using Javascript in zope applications. I would like to use Ext JS (http://www.extjs.com/ ) in an application that I am writing. It is a fairly extensive library, so I didn't really want to copy/paste every single file into a dtml method. I looked all over the place for some discussion on this subject, but only found things relating to plone (which apparently has a javascript registry); however, I wish to stay away from plone for this particular application. What should I do to use these libraries? Is there a canned solution for this sort of thing? Thank you much! -Matt

Hi! I plan to create a product I call Zope Smart Manager that consist in a view similar to freemind for Zope You could see a picture of my prototype here: http://blogs.sistes.net/Garito/images/ArbolYanged.png The idea is create a series of monkey patches to all the products we are interested to see as tree nodes and a series of javascript (prototype + scriptaculous) for the "client side" I plan this ZSM view will be my main work view with edition and creation For that I need some help about how to create the simplest monkey patch and the javascript objects I have no experience with monkey patching zope nor javascript object but I'll learn all the necessary skills if no one wants to help Can you help me at any point? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito
