Creating a Folderish class in Python Product
by Shalabh Chaturvedi 26 Feb '00

26 Feb '00

Hi all, I am creating a new product with one class - called ProjectFolder - which needs to be 'folderish'. So I derive my class ProjectFolder from ObjectManger and after restarting Zope I am able to create objects of class ProjectFolder. The problem is when I add any objects under a ProjectFolder object, they get added under the ProjectFolder's parent! That is, they get added under the folder which contains the ProjectFolder object and become siblings instead of children. Any idea what is going wrong? I feel that my ProjectFolder objects somehow do not have full folderish capabilities and the calls for 'add some object(x)' to ProjectFolder are getting handled by methods acquired from the parent folder. As a result the object x gets added under the parent folder. What can I do? For creating 'folderish' classes isn't the ObjectManager base class enough? Thanks in advance, Shalabh

[ZGotW] Issue #6 (Open)
by Zope Guru of the Week 26 Feb '00

26 Feb '00

A new issue of "Zope Guru of the Week" is available: =================================================================== Issue #6 -- standard_manage_header =================================================================== Status: Open Zen Level: Disciple (3/8) Keywords: Management Interface Submitted by: Dylan Jay djay(a)innocent.com ------------------------------------------------------------------- When I create a ZClass with my own management methods they will by default use standard_html_header etc. This doesn't look like the standard management interface. I think we should have a standard way of making all management interfaces look the same. In fact this should be able to be changed for any subset of management interfaces so you could for instance change the way the standard zope interfaces look. *Ed. I split Dylan's proposed solutions into a separate reply.* ------------------------------------------------------------------- To reply and win undying glory and mondo guru points: http://zope.palladion.com/demos/ZGotW/6

[ZGotW] Issue #5 (Closed)
by Zope Guru of the Week 26 Feb '00

26 Feb '00

The current issue of "Zope Guru of the Week" has closed: =================================================================== Issue #5 -- Rendering DTML in Properties =================================================================== Status: Closed Zen Level: Disciple (3/8) Keywords: DTML ZClasses Submitted by: Chuck Burdick chuck.burdick(a)tradingtechnologies.com ------------------------------------------------------------------- This problem occurs when you try to make a DTMLDocument-ish ZClass. 1. Suppose you have created a ZClass that you call 'myClass'. 1. Give 'myClass' a property sheet called 'properties'. 1. Create a text property called 'content' on 'properties'. 1. Create a view to edit 'properties'. 1. Create an instance of 'myClass'. Q: If you put dtml tags in 'content', how can you render the object and interpret the tags? For example, suppose you created 'index_html' as a DTMLMethod in 'myClass' as:: <dtml-var standard_html_header> <dtml-var content> <dtml-var standard_html_footer> This will not work. It will display the text value of 'content' but the dtml tags will not have been evaluated. This is a problem I frequently encounter. I do not want to create a complicated subclass of the existing DTMLDocument classes. Instead, I want a quick-and-dirty ZClass in which DTML tags are valid. ------------------------------------------------------------------- Reviewed by: Tres Seaver tseaver(a)palladion.com ------------------------------------------------------------------- What, no valiant Zopemeister would step up to the plate? OK, here is my take on the problem. Short Answer You can't do this "quick and dirty". Long Answer Standard DTML and Python methods do not have direct access to the DTML rendering machinery, which lives in $ZOPE_HOME/lib/python/DocumentTemplate/DT_HTML.py and in $ZOPE_HOME/lib/python/DocumentTemplate/DT_String.py. A quick scan of those files convinced me completely that I wasn't going to replicate it in a Python method or two. So how do you accomplish your goal? The simplest technique would be to morph your ZClass so that it inherits from ObjectManager -- you can then stash the 'content' field's DTML into a DTML Document, say 'content_dtml', contained within the instance, and render it from your 'index_html' with the exact syntax you specified. You might even be able to use the same user interface as your first cut: in the form processing method, for instance, you could add:: <dtml-call "content_dtml.manage_upload( content )"> Another answer involves hacking the dtml-var tag to allow for a 'fmt=dtml' parameter, which would then do the recursive rendering of the property value. -------------------------------------------------------------------

More sybase weirdness
by jiva＠devware.com 26 Feb '00

26 Feb '00

So I got the SybaseDA working, but now I notice that my REC_ID's (these are autoincrementing numeric columns in my tables) seem to always show as their number and an L. So like REC_ID 10 would be 10L to the zope DA. In ISQL they come out fine. What's the deal? -- Let us never negotiate out of fear, but let us never fear to negotiate. -- John F. Kennedy

Sybase DA problems! Need help!!
by jiva＠devware.com 26 Feb '00

26 Feb '00

So, I dunno what I did, but somehow I broke my sybase DA. I can import the sy_occ module into python just fine, but when I put it into my product subdirectory, zope stops running. It doesn't give any errors or anything, it just won't start. What did I do?? Someone please help! SybaseDA version: 2.0b2 Zope version: 2.1.4 Python version 1.5.2 OS: RedHat Linux 6.1 (Fresh Install) Sybase version: 11.9.2 -- HUGH BEAUMONT died in 1982!!

Q on dtml-methods parameters and Renderer/ZLink and self
by Chris Niekel 26 Feb '00

26 Feb '00

Hi, I'm quite new to Zope and I want to implement a 'special' link class. I found Renderer (which solved my first problem) and ZLink is a good base for the rest of my project. What I'm trying to do is that i can do <dtml-var "links.slashdot"> in my documents, and that in the output <a href="http://slashdot.org">slashdot</a> appears. I've got that working. My next step is that I want to create an intermediate page that says something like: URL: slashdot.org Note: Last time I checked, this site was down. So (and now comes my question), in a dtml-method of my ZLink class, I want to include the url of the link-object. I tried a <a href="&dtml.url-spam;"> from jim's howto, but the class method doesn't know the name of the object, and "self" doesn't work. Although I'm not making myself clear (I think), I hope someone can provide me a hint or an answer to how my method can use the url of 'self'.

dtml-in
by Kevin Meinert 26 Feb '00

26 Feb '00

Having trouble with dtml-in, it seems to affect the current object "space" you're in? Im not sure about what all dtml-in affects, please take a look: ( just putting "cool_poll" in the kevntest object does not work, the cool_poll/index_html object actually needs to be called for somereason. Im using the "poll" module from the zope site ) Here's my object hierarchy: - root + squishdot - index_html + kevntest - kevnpoll + poll - index_html Including the following in root/squishdot/index_html does *not* work: (see error below) <dtml-with kevntest> <dtml-in "objectValues(['DTML Method'])"> <dtml-var title><BR> <dtml-var sequence-item> </dtml-in> </dtml-with> Including the following in root/squishdot/index_html works: <dtml-with kevntest> <dtml-var kevnpoll> </dtml-with> The file root/squishdot/kevntest/kevnpoll contains: <dtml-with cool_poll> <dtml-var index_html> </dtml-with> And here is the Zope server error Im getting, when it does *not* work: Zope Error Zope has encountered an error while publishing this resource.

26 Feb '00

Hello Zopistas FSSession 0.2.3 is available at: http://www.zope.org/Members/gaaros/FSSession FSSession 0.2.3 uses cPickle for more flexibility and it is therefore incompatible with Session data stored with the older version. It adds a few more options, including a noCookie option and the README contains a more complete example of usage, implementing a Sticky form. Pavlos

Re: Stop zope from adding <html><head></head> to my method
by Tom Neff 25 Feb '00

25 Feb '00

#1, it is absolutely NOT the browser that adds HTML and HEAD tags to the output from DTML methods. It is some default behavior in the ZPublisher. Verifying stuff like this takes about 20 seconds using Lynx and/or Telnet, even if you don't grok Zope internals. I strongly urge David and others not to post untested guesses as answers to specific technical questions here - it has the potential to confuse hundreds of readers. #2, there is a much simpler way to override Content-Type and other HTTP headers in any DTML Method: simply put them as the first lines in your method body, separated from the rest of the body content by a blank line. Try it: create a DTML Method called 'tom_is_great' and edit this in: +----------------------- |Content-Type: text/xml |X-Tom-Status: right as rain | |<document title="Tom is right"> |<status>Amazing...</status> |</document> | +----------------------- [Change] Now go look at it in IEXPLORE or dump it with Lynx, and voila. Modesty in three colors. :)

RE: [Zope] ODBC/SQL newbie question-DSN-less connection?
by Sean Kelley 25 Feb '00

25 Feb '00

Thanks- I was trying to create the method under the ZSQL Methods product, not the ZODBCDA product I added. Is there a way to create a database connection to something like an MS Access database file when you cannot create the DSN on the server?
