Create top-level folder
by Matt Ficken 06 May '03

06 May '03

Part of my product's job is to create a top-level folder. I can have it do that only when, from the management interface's "add function", I add it to the root directory. I would like it to always be able to go to the root directory, regardless of where its added. In order to do this, I need to access the root directory object, but I don't know how. What function can I call to return the root directory object? Would 'getPhysicalRoot' do what I want? if yes, what do I call it on? -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup

Weird acquisition behavior of Page Templates
by Paul Winkler 05 May '03

05 May '03

Here's a puzzler... So we all know how you can use context acquisition by visiting various URLs in the browser, right? E.g. if let's say we have a folder in the zope root, called my_folder. Let's say it contains an image, a dtml method, and a page template called respectively my_image, my_dtml, and my_pt. Now we all know that if you browse to /my_folder/my_image/my_dtml, you'll see my_dtml rendered. my_image just gets added to its acquisition path. Likewise if you visit /my_folder/my_dtml/my_template, you'll see my_template rendered, with my_dtml at the end of the aq_chain. And if you visit /my_folder/my_template/my_dtml, you'll see my_dtml with my_template on the aq_chain. except the last one is not true. :-P As far as i can tell, if you put a page template anywhere in the URL, it gets rendered no matter what else comes after it in the URL. /my_folder/my_template/foo/bar/baz... no matter what, you get my_template rendered. what the hell is up with that? Bug? try it yourself. zope 2.6.1. -- Paul Winkler home: http://www.slinkp.com "Muppet Labs, where the future is made - today!"

index_html not acquired with SkinnedFolder based product
by David Hart 05 May '03

05 May '03

Hi, I have a product based on SkinnedFolder, among other classes. I don't understand why index_html is not being acquired. Brian Lloyd wrote on 2003-01-02 in thread "Why is index_html() called instead of ..." : >ZPublisher looks first for index_html, and will only use __call__ >if it doesn't find an index_html on the published object. > I'm *not* setting index_html = None, or similar. What am I missing? I've written my own __call__ method, probably needlessly, to try to get around the problem. -dave

any way to get older style error_tb?
by Michael Best 02 May '03

02 May '03

The object names and the filenames are left off of the newer error type and that makes it hard to figure out which of many objects which may be called together to publish a page was responsible for the error. The Filenames in this case aren't a big deal...but what happened to the Object names? I can provide a more detailed example of missing details later too when I get it from our developers. -Mike Zope 2.4.3 style: Error Type: error Error Value: ACK Traceback (innermost last): File /usr/local/Zope-2.3.3/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.3.3/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: fake_error) File /usr/local/Zope-2.3.3/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: fake_error) File /usr/local/Zope-2.3.3/lib/python/OFS/DTMLDocument.py, line 189, in __call__ (Object: fake_error) File /usr/local/Zope-2.3.3/lib/python/DocumentTemplate/DT_String.py, line 540, in __call__ (Object: fake_error) File /usr/local/Zope-2.3.3/lib/python/DocumentTemplate/DT_Raise.py, line 128, in render (Object: error) error: ACK Same Error, Zope 2.6.1: Error Type: error Error Value: ACK 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 OFS.DTMLMethod, line 126, in __call__ * Module DocumentTemplate.DT_String, line 474, in __call__ * Module DocumentTemplate.DT_Raise, line 56, in render error: ACK -- Michael Best Systems Administrator ph 780-413-6397 x230 Emergence By Design fax 780-433-7548 #200, 11209 Jasper Avenue toll 866-860-2666 Edmonton, Alberta, T5K 0L5

Catalog Aware
by MidnightFears＠aol.com 02 May '03

02 May '03

I have made my top-level class CatalogAware. This class consists of hundreds of compound data elements that are not specifically declared to be CatalogAware, yet they are grouped into one index recorded for the top-level class. I know in order to get the delete, cut, copy, and paste functionality to work in reindexing items I need to override these methods. However, this has no effect on reindexing a simple compound element when it is the only item cut and pasted, deleted, etc. My question is, should I override the main functions that control these operations from the manage_main view? I have already made modifications to the presentation logic of manage_main. Is overriding the button functionality a 'smart' thing to do? I need the delete operation to perform other tasks as well, i.e. when an object of a certain meta_type is deleted, a mirrored folder structure at the root should be automatically deleted as well. thanks, stacy

Most browsers try to show content as fast as possible. There are even CSS-standards for making it possible to predict a tables layout ahead to be able to render it as fast as possible (before it is completely loaded). The main reason of this I guess is because people usually start reading the top of the page and showing it make it appear to load faster for the visitor. Hence, your browser/site appears faster. My tests shows that both Moz and IE shows content sent so far even if the session has not finished or the file is completely transmitted. (I got the feeling that this was the intended behavior in the original question (?)) Also interfaced gif images are shown as soon as possible, I guess movie clips and flash movies also behave that way. This could be useful for other stuff as well (except streaming large object, which should never be saved in the ZODB by the way, be cause it bloats the memory when the object is loaded. It should be stream from a file, and not by reading the entire file as most file system object product I reviewed does including LocalFS which I have made a patch for). One use would be sending response in a long-time execution of a pack or other maintenance activities. It's a great thing to see how the process get along and that it's not halted. In such a process you can't predict the Content-Length, because you don't know ahead what messages the might pop-up. So the question is what happens if the Content-Length is excluded. In my test with text/html content nothing happens and it works fine. Other content types may behave differently depending on the client.

Hi, Say I have a ZCatalog with a ZCTextIndex called 'SearchableText' and a DateIndex called dateofpublication. I do a search like: results = MyCatalog(SearchableText = search_expression, dateofpublication = search_expression2) How would I get those results sorted by the relevence returned by the ZCTextIndex? cheers, Chris

RE: [Zope-dev] RFC: RelationAware class for relations between obj ects
by sean.upton＠uniontrib.com 29 Apr '03

29 Apr '03

My observations from a digital-media management perspective lead me to believe that relationships and other metadata are closely intertwined, and that there needs to be a way to righcly express metatdata about relationships. One the subject of simplicity vs. features - it should be said that one thing that high-level applications would likely need to bolt on top of these relationships is metadata about those relationships. In the keep-it-simple model the descriptor names (Python identifiers, ie self.developers referencing a relation object) serve as an id for one half of the relationship, but how does one attach to following to that half of the relationship: - relationship type/model (same as DCMES relation qualifiers) - relationship label/plain-text-title - content type or class of related object - id/reference or path to content - potentially some other data? Examples (warning: long post): http://mail.zope.org/pipermail/zope-cmf/2002-October/015801.html In a keep-it-simple model, where does this high-level stuff belong? In a global service?

Boy, that's a lot of mechanism. It would be nice if the relation support could be kept simple.

RE: Curious Problem
by stuffduff 29 Apr '03

29 Apr '03

I've spent most of the day recreating the setup from scratch, just to rule out a python problem. I built python 2.1.3 from source, then used that python (renamed python2.1.3) to build zope from src. I can still run from the command line, but not from zope; same error as before. One thing I tried was to move the class definition inside the function definition (how could zope miss it? ;) ) but still no joy. I just don't understand why zope even needs to see the class. The function reads a record from an rdbms, unpickles and uses a few object properties to build a string. Something in zope itself seems to be preventing this. Any other thoughts?
