ZMI icons 'gone pecan'
by Danny Morgan 19 Nov '02

19 Nov '02

I don't know if this is a function of an upgrade to Zope 2.6, or rather assigning a new icon to a zclass product I'm working on. In any event, the standard icons for folders, templates, and the like are reduced to text and x's. I have not yet been able to figure out cause or solution. Any help or pointers will be appreciated.

Re: [Zope] Data.fs falls into 33GB hole
by Howard Hansen 19 Nov '02

Packing fixed the problem, and I originally pooh-poohed this idea, because it would create another 30G file right? On second thought I think I'm wrong. It only exports the latest version of each object, skipping all prior history. If that's true, I could have exported it to a file (approximately 350MB) and imported it elsewhere. --- Jaroslav Lukesh <lukesh(a)k-net.cz> wrote: > | Odes�latel: Howard Hansen > <howardahansen(a)yahoo.com> > | 1) Can I safely pack a database this huge on my > live > | machine? > > Export to ZEXP and import at another Zope? > > REgards > > JL. __________________________________________________ Do you Yahoo!?

parameters from dtml to python
by Jorg E. Rødsjø 19 Nov '02

19 Nov '02

I have an external method(python): def makePhoneList(searchString, *sortBy): Then I want to be able to call it in a dtml-document like so (wrong, I know, but to illustrate what I am looing for). <dtml-in expr="makePhoneList(searchString='foo', '<dtml-var sortBy1>', '<dtml-var sortBy2>')"> The sortBy1 and sortBy2 are variables in the DTML-document. But I am having problems with the arguments. Possibly due to the fact that my function specifies *sortBy as a list of parameters. Any suggestions would be appreciated. Jorg Rødsjø EDB-HF NTNU

Recursive Python Call in Zope
by Christopher Baumbach 19 Nov '02

19 Nov '02

Hello, i'm a Zope newbie from germany - 'Hi all !!' Now, here's my first problem: i'm trying to read my folder-hierarchy with a python script, which takes one arg (a folder object). The script runs fine, but the recursive 'script(subfolderObject)'-Call doesn't take effect. It seems, that nothing happens. But if I do an infinite recursion, Zope gives an error... Thank you, for help... C. -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet. Rund um die Uhr für 1 ct/ Min. surfen!

Returnvalue of manage_addProduct
by Andreas Tille 19 Nov '02

19 Nov '02

Hello, I lilke to add some further properties to a newly created object. The object is created like this: new = container.manage_addProduct['ExtFile'].manage_addExtFile(id, \ id, desc, file) Now I wanted to add a further property using new.manage_addProperty(id, type, value) but I found out that new is 'None'. On the other hand I have seen in some examples that manage_addProduct does return the id of the new object. Any hint why it does not so when adding an 'ExtFile' object? What would be a clever method to obtain the new object quickly? Kind regards Andreas.

RE: [Zope-dev] Production System Specs
by sean.upton＠uniontrib.com 18 Nov '02

I've redirected this to zope(a)zope.org, since I think deployment topics are more likely to generate a good discussion there. My take: Load-balancing: Use squid and ICP support in Zope 2.6 to load balance. Consider using directory storage for your backend storage because backup and replication of your ZEO storage server's storages (for high-availability clustering) can be done with standard Unix command-line tools. Hardware: depends on what you are trying to do; for ZEO clients: lots of low-end dense 1CPU app servers (blade servers), or 2CPU AMD boxes with plenty of ram running two Zope instances bound to each CPU (assumes CPU affinity is possible in your OS)...both setups might work. Caching: cache what you can with Squid, and if you can, tune your ZEO clientstorage connection cache to fit your needs. If a lot of pages on your site are cacheable, cache them in Squid, which has more tunable caching than Apache. There is no one-size-fits all answer for hardware, unfortunately. Questions worth asking: - Do you need physical density (do you rent rackspace at a premium)? - How cacheable (at the page level) are your applications? News delivery is very cacheable, but personalized ecommerce sites are not. - How much content are you going to store in the object database? - How CPU intensive are your applications? How memory intensive? - How much traffic do you expect to see to your site? - What particular processes are very intensive, and how do you think you want to partition them? Think about things like bulk reindexing or adding of content, etc. I'll give you my thoughts if you have more specific answers to some of these questions...

The container has no security assertions
by Mark McEahern 18 Nov '02

18 Nov '02

[Using Zope 2.6 final on Red Hat 7.3 with Python 2.1.3] I have a CMF portal type that's implemented as a Zope Product. I need to make a fairly complicated report for published content of this type. My basic approach is to take the portal_catalog.searchResults and stuff them into a Python class that provides access to the results in a way that facilitates the report. Where I'm stuck is that I just don't know how to get at that Python class from the Page Template where I do the report. I'm happy to provide as many details as possible, but I'm hoping at first to sketch the broad outlines of what I've tried, since I think what I'm missing is some basic understanding of the security model--that seems to be the particular wall I'm running into... I have a Python class that does not need to persist. I call it a DisplayBag. It sits in a module in the same folder as the portal type: PressRelease/ __init__.py DisplayBag.py PressRelease.py --> the portal_type DisplayBag.py looks like this: from AccessControl import ClassSecurityInfo from Acquisition import Implicit import Globals class DisplayBag(Implicit) security = ClassSecurityInfo() security.declareObjectPublic() def __init__(self, ...): # nothing really special security.declarePublic('years') def years(self): # nothing really special # other methods, similar to years, nothing really special Globals.InitializeClass(DisplayBag) The current hack I use to "get at" DisplayBag is with a method tacked onto the PressRelease class. (I've tried getting at the DisplayBag from an external method. I've had the same basic problem--the error indicated below.) class PressRelease(Document.Document): meta_type = 'Press Release' security = ClassSecurityInfo() def __init__(self, ...): # nothing really special # other methods--nothing really special security.declarePublic('make_bag') def make_bag(self, search_results): d = PressReleaseDisplayBag(search_results) # I've also tried __of__, which makes no difference (i.e., same error). # return d.__of__(self) return d InitializeClass(PressRelease) Then, in a skins folder, I have a PageTemplate called press_releases.pt. What this does is gets the published Press Releases and then, hackishly, takes the first one (so I have a PressRelease on which to call make_bag), do getObject() on it since searchResults doesn't give me the object, and call make_bag. I get the DisplayBag just fine--I've used tal:content="results" ('results' is the bag) to display it. But then when I call the years() method of the bag: <div tal:define="raw python:here.portal_catalog(portal_type='Press Release', review_state='published'); first_pr python:raw[0].getObject(); results python:first_pr.make_bag(raw)" tal:repeat="pr_year results/years"> I get this in the error_log (I have VerboseSecurity 0.4 installed): [snip lots of detail, this is at the tail end of the traceback...] Module Products.PageTemplates.Expressions, line 206, in __call__ Module Products.PageTemplates.Expressions, line 194, in _eval Module Products.PageTemplates.Expressions, line 150, in _eval __traceback_info__: results Module Products.PageTemplates.Expressions, line 346, in restrictedTraverse __traceback_info__: {'path': ['years'], 'TraversalRequestNameStack': []} Module Products.VerboseSecurity.VerboseSecurityPolicy, line 157, in validate Unauthorized: The container has no security assertions. Access to 'years' of (PressReleaseDisplayBag instance at 86746f8) denied. In the short-term, I wonder what magic incantation I need to use to workaround that error. Long-term, I wonder, Is there a better way for me to use Python in Zope that isn't just so plain hard and contorted? The reason I felt I needed to make the DisplayBag class and not just do all the stuff it's doing either in Python Scripts or TAL is that--well--it seems like it will be easier to test and maintain. I could have a profusion of scripts in the skins folder that effectively do the same thing. And I'd probably already be done, but I'd really like to figure this out. I have this itching suspicion that I haven't provided enough detail--or that I haven't summarized well enough. Thanks for any insights or suggestions you can offer. // mark -
