DTML Call Fails
by hpinson＠indepthl.com 24 Oct '06

24 Oct '06

A little bit of legacy DTML fun here... Zope 2.9.3 On save of a DTML Method, why would this dtml-call fail: <dtml-let standards="REQUEST.SESSION"> <dtml-call "standards.set('AR-DA-08', AR-DA-08)"> </dtml-let> With the error: "Expression (Python) Syntax error: invalid token" Whereas this works fine: <dtml-let standards="REQUEST.SESSION"> <dtml-call "standards.set('AR-DA-07', AR-DA-07)"> </dtml-let> Any insight is appreciated. -- Harlow Pinson Indepth Learning Email: hpinson(a)indepthl.com Phone: 505 994-2135 Fax: 505 994-3603

Accessing ZPT properties from another page
by Dyyryath 24 Oct '06

24 Oct '06

I've got a page template that I'd like to display some information contained in the properties of another page. Can I do this? I'd like to do something like: <div tal:content="context/otherpage/template/propertyname"></div> Though that obviously doesn't work. :) Does anyone know if something along these lines is possible?

Uploading photos into newly created objects
by Peter Bengtsson 24 Oct '06

24 Oct '06

I'm trying to upload a Photo into a newly create object in my product class. The code looks something like this:: def manage_addSomething(dispatcher, id, title, photofile): destination = dispatcher.Destination() instance = Something(id, title) destination._setObject(id, instance) obj = destination._getOb(id) # at this point, is 'obj' wrapped in aq stuff??? _adder = obj.manage_addProduct['Photo'].manage_addPhoto _adder(id='', title='', file=photofile) class Something(Folder): def __init__(self, id, title): self.id = id self.title = title The error I get is: File "/home/peterbe/zope/zope285/Products/Photo/Photo.py", line 664, in manage_addPhoto dest._setObject(id, photo) AttributeError: _setObject I'm using Photo product 1.2.3 but I don't think it matters if it's a Photo I'm trying to add or any other product. If I add the photo after the transaction has been completed in a separate request it works fine to add the photo to the recently created object. Any idea? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

ZSQL Method's Precision
by Jason C. Leach 24 Oct '06

24 Oct '06

Hi: In a PostgreSQL DB I have a Numeric data type with a precision of two decimal places. If I have 1.33 in as the result from my query, it's everything is good. However, if I have 1.30 it reduces the precision to one decimal place and I get 1.3. Not so good when dealing with currency ( I don't want to use the money data dype ). Any ideas on how I can get my ZSQL method to keep two decimal places? Thanks, Jason. -- ........................................ .... Jason C. Leach .... PGP Key: 0x62DDDF75 ....

I assume you get a float type from the DB. 1.30 *prints* as 1.3 but has around 12 decimal digits of precision. -- Gabriel Genellina Softlab SRL __________________________________________________ Correo Yahoo!

reading text file object
by Allen Huang 23 Oct '06

23 Oct '06

I made a template that changes the location name and content due to the information stored in the title property variable and the file content of a "File" object. I used the dtml tag <dtml-var title> to call the "title" information but I don't know of any dtml tag that would call the content other than calling the "id" of the File object. ex. File object "test" Call method "<dtml-var test>" Could anyone help out. Is there any other ways to call the content of the text "File" object?

Representation for Zope at PyCon 2007
by Jeff Rush 22 Oct '06

22 Oct '06

PyCon 2007 will be held in Addison (Dallas) from Feb 23 to 25, and we're fast approaching the talk submission deadline of Oct 31. I'd like to encourage talks about Zope, particularly "how to get started with Zope" and also the new technologies coming out of Zope 3. Information on both of those topics has been in very short supply at PyCons. We're also approaching the deadline, Nov 15, for half-day tutorials taught on Feb 22. Attendees register separately for these and teachers can earn up to $1500 per half-day, depending upon the number of students. The tutorial format would be ideal for getting someone up to speed on either Zope 2 or Zope 3. Teach a basic intro in the morning and advanced material in the afternoon. And if you're nervous about such a commitment, tutorials are a great opportunity to partner with another teacher or class helper. As a longtime advocate of Zope (both 2 and 3) I'd very much like to see extensive coverage this year of getting started with Zope 3. Zope has a PR problem, partly from the immense power that comes with it, and the difficulty in getting your arms around it all. It evokes strong feelings and has a distinct philosophy and design tradeoff that you have to understand before you're productive. And with the recent formation of the Zope Foundation, putting forth your best image and getting new members into the community should be a priority. PyCon is a significant opportunity for the Zope community to evangelize. In the PyCon's I've attended one challenge is breaking Zope down into teaching chunks that can be taught in 30-40 minutes. It is very easy to leave the audience behind in the buzzwords and concepts of Zope. So please don't try to teach all of Zope + Plone in 30 minutes. ;-) ;-) One possible talk I think would fit, would help someone just getting into Zope 3 and I wish someone would tackle is the Zope 3 component architecture - nothing about the web or databases or security. Start with the abstract concept of interfaces and adapters, as exists in the zope/interface package, and then layer on it the idea of registries, as implemented in the zope/component package. And wrap up with the reasons why interfaces are better than abstract base classes and what kind of problems adapters are good at solving, including some _non-abstract_ examples. If you'd like to get involved, check out the following conference pages: http://us.pycon.org/TX2007/CallForProposals http://us.pycon.org/TX2007/CallForTutorials Django and TurboGears will be at PyCon in force; I hope Zope will be too.

zwiki users - own color text?

20 Oct '06

hi all I've had a search thro the mailing list, but can't find out how to set up zwiki so that each user's contribution to a wiki automatically shows up in a particular color, or failing that how the user themselves can change the color of their contribution... i have access to a server running zope (but i can't change or install anything on that server), and can add users etc to the zwiki available on there. any ideas appreciated thanks roy -- Search for products and services at: http://search.mail.com
