Security Design Patterns
by Robert Jean 17 Sep '03

17 Sep '03

Hello, Does someone know of a good resource discussing the most common security design patterns (users, roles, proxy, local roles, etc.)? The Zope Book has a section on this topic, but it is quite basic. Thanks, Robert __________________________________ Do you Yahoo!? Yahoo!

Does anyone know of Training for Plone/CMF/Zope?
by Jet Wilda 17 Sep '03

17 Sep '03

Would you all be so kind as to recommend some training options that are available for Plone/CMF/Zope. We are particularly interested in using Plone/CMF and developing e-commerce capabilities that would integrate into Plone/CMF. We are located in Saint Petersburg, FL. A scenario that could work is for a consultant to come and join us for a project as lead architect/developer. We would include additional time for training/knowledge transfer. Thanks Jet

Automatic Restarts?
by prosam＠comcast.net 16 Sep '03

16 Sep '03

Hi All, Zope keeps restarting on its own. Why is it doing this? We are running Zope 2.61. It is really becoming a headache since we are running and eCommerce site. Everytime it restarts you get a Proxy error on the site until it is done. You can imagine how annoying this would be especially to our customers. Can somebody please help? Thanks, Samuel Mateo, Jr. Web Designer www.DinnTrophy.com

Unpack, "You are not allowed to use unpack..."
by Jerry Westrick 16 Sep '03

16 Sep '03

Hello Zopistas.... I'm trying to read a binary file from within zope... It's format is rather simple, but it does a length stored as an Unsigned long. In a test program, I used to struct.unpack(...) to read in the unsigned long... Unfortunatetly, Zope don't want me to do this 8-( Is there a work around? Is there a work around, or must I create an unpack(..) external script just to get this value? Jerry Westrick...

Re: Adding attributes to PageTemplateFile

On the other hand, if I remove self and just return _addFooForm: def manage_addFooForm(self,*args,**kw): """manage_addFooForm method""" kw['Kind']='Foo' return _addFooForm(*args,**kw) I get this error: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Products.Foo.Foo, line 81, in manage_addFooForm Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 281, in _bindAndExec Module Shared.DC.Scripts.Bindings, line 1, in ?

Any ideas? Thanks in advanced, Josef

restrictedTraverse versus unrestrictedTraverse versus simpler notations
by nwingfield＠che-llp.com 16 Sep '03

16 Sep '03

Q1. What is the difference between restrictedTraverse and unrestrictedTraverse? When would one use the latter over the former? Q2. In product code, what is the value in using 'self.restrictedTraverse(id)' or 'self.unrestrictedTraverse(id)' versus simpler notation, such as 'self[id]' or 'getattr(self, id)' ?

RE: [Zope] RESPONSE.Write question
by Passin, Tom 16 Sep '03

16 Sep '03

[ Small Business Services] > I have been trying to get a test routine working that uses > RESPONSE.write... > without success: 1) RESPONSE.setHeader() affects the RESPONSE object. But that does not mean that anything is actually sent to the browser at that time. You need to flush the RESPONSE object (though I do not know if that does anything before RESPONSE.write() has been invoked). 2) It is invalid to mix non-header material in with the header. Just because some browsers handle it gracefully is not a good reason to do so. 3) Not all browsers will understand chunked data transfer. If you want to see how long you are waiting for a response, you can invoke your page by submitting a form, and using javascript, load a page that only says "Starting..." When Zope does send its response, it will overwrite that temporary page. I have used a similar method - although I always had the response come up in a second frame, and i am not sure if this will work if you only have a single frame. Another approach is to have your response open in another frame or in a popup window. Any of these variations will let you see the start and end of the response.
