Resize a image stored in a Oracle's BLOB Field
by Juan Javier Carrera Obrero 27 Nov '01

27 Nov '01

Hello, Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with: <dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in> However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', align='left')">). How can I do it ? Thanks again !

Re: [Zope-dev] Acquisition wishlist :-)

As a side effect to turn off acquisition, you defined the attribute. This will not play well with inheritance: You will not only prevent acquisition of "index_html" but also prevent inheritance of it (which may be really necessary in some contexts). Dieter

Acquisition/cDocumentTemplate bug
by Dieter Maurer 06 Oct '00

06 Oct '00

Recently, several posters have reported strange "AttributeError __call__" exceptions. The most precise was a report by Oleg Broytmann: /index_html DTML Document <dtml-var standard_html_header> /standard_html_header DTML Method <dtml-with sub></dtml-with> /sub Folder When he calls "/sub/index_html", he gets this "AttributeError __call__" for "sub". He observed the problem on Zope 2.1.4 and 2.2a4. I partially analysed this problem report under Zope 2.1.6: In "MM_cget", "sub" is retrieved as an "ImplicitAcquirerWrapper" (correct). In line 373, however, "PyCallable_Check(sub)" returned "1", which is probably wrong, because a folder is not callable. The "ImplicitAcquirerWrapper"'s "tp_call" mislead "PyCallable_Check". In line 376, the attribute "py_isDocTemp" is looked up and succeeds. Therefore, the folder "sub" is seen as a Document Template, which definitely is not true. The following call fails because it arrives at CallMethodO in "Acquisition.c:119" which looks for a non-excisting "__call__" method. Dieter

ZPatterns: DropZone example
by Steve Alexander 20 Sep '00

20 Sep '00

Hi folks, I've been looking at the DropZone example Phillip Eby provided on the ZPatterns Wiki. http://www.zope.org/Members/pje/Wikis/ZPatterns/DropZoneExample I've decided to start implementing it, so as to give myself an educational experience in using ZPatterns. I have an open question: The suggested specialists in the Accounting framework are: Invoices Orders Customers Products What I'm finding is that these are just the White-box specialists. A clean design would seem to want all the specialists above, plus at least one Black-box specialist to do the "heavy lifting. Let's call it the "AccountingProcessor" specialist. Now, if I had a third-party accounts package (something by Sage perhaps), I could make the AccountingProcessor specialist expose various functions to the four other White-box specialists. It would implement these by making equivalent calls on the underlying accounting package. I could also swap the heavy-lifting portion of my framework by swapping the black-box AccountingProcessor specialist for one that talks to some software by Quicken, or perhaps some software that is written in Python as a conventional Zope product. The same goes for the Resource Scheduling framework. We have some White-box specialists, ripe for customisation: Resources Reservations ResourceUsers And then for the heavy-lifting we have the black-box ResourceScheduler specialist. Again, this might be a Zope Python Product, or it might be an interface to some application written on top of Microsoft Exchange. Are specialists intended to be placed inside other specialists, as "contents"? So in this case, would the white-box specialists live inside the black-box specialist -- so they become the customisable aspects of the overall framework? Or would both black-box and white-box specialists live inside an uber-specialist? Or is this just down to taste? -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Acquisition Confusion :S
by Chris Withers 15 Sep '00

15 Sep '00

Hi Jim, (or any zope-dev'ers who can explain this ;-) I've just been reading: http://www.zope.org/Members/jim/Info/IPC8/AcquisitionAlgebra ...and I've got confused on the 'Getting the containment wrapper' section. In anser to 'What is A.B.C.D?' I can't see how you can get: ((D o (C o A)) o (B o A)) Here's my working: A.B.C.D = (B o A) : .C.D = ((C o A) o (B o A)) : .D = ((D o C) o ((C o A) o (B o A))) You can't apply the simplification: ((Z o Y) o (Y o Z)) to the leftmost section 'cos the brackets are in the wrong place... so how to you make the jump to: = ((D o (C o A)) o (B o A)) (but should it?!) Also, is the definition "aq_inner is obtained by finding the innermost wrapped object" the same as "aq_inner is the 'self'/'object' part of the current aquisiton wrapper"? Confusedly and looking for help, Chris

No, it shouldn't :( SimpleItem.Item has __allow_access_to_unprotected_subobjects__=1 in it, so it just masks the problem rather than solving it properly... cheers, Chris

This is already being setup as part of the patch and small change integration page... more details once it's up this weekend ;P you will like. >>> Message: 9 Date: Thu, 24 Aug 2000 15:09:32 +0100 From: Chris Withers <chrisw(a)nipltd.com> Organization: New Information Paradigms To: Adam Karpierz <karpierz(a)itl.pl> CC: "zope-dev(a)zope.org" <zope-dev(a)zope.org> Subject: [Zope-dev] Voting for Patches? Adam Karpierz wrote: > There is a patch for it: > http://classic.zope.org:8080/Collector/1540/view I wonder whether it'd be worth enabling people to vote on what patches they'd like integreated and what bugs they'd like solved in the collector? The one for me is the ability, in effect, to shout 'Me too!' when I see a bug that I've experienced too. Maybe this would help filter down the collector or at least give anotehr way that it could be prioritised? cheers, Chris <<

Bugs in new Security Stuff :P (part1)
by Chris Withers 14 Sep '00

14 Sep '00

Right, firstup this thing about HTMLFile's which form part of the management interface. Why are they totally immune to the security stuff? It gets really confusing when something works fine in a management screen and yet breaks everywhere else, especially when it's not throwing a security error (more in part II ;-) So, why is it like this? cheers, Chris
