Quick question about <dtml-if ...>
by George M. Ellenburg 08 May '02

08 May '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thanks to everyone for pointing me in the right direction the other day. I have a quick question regarding <dtml-if ...> (I'm up to Chapter 4 in the Zope Book right now.) If I have a URI like this: GET /foo?a=3 And the corresponding DTML contains: <dtml-if expr="a=3">  </dtml-if> ....Wouldn't this evaluate the Python expression? I've tried doing: <dtml-if a=3>  </dtml-if> But received a syntax error. So I guess my question is, I thought the expr argument brought the DTML script outside the scope of the website. I'm not trying to call any external methods. Have I completely lost it now? ;-) (Don't answer that, please.) Regards, - -- George M.

Re: [Zope] how to access the owner of an object?
by Brian Lalor 08 May '02

08 May '02

Following up to my own post here, after finding the answer pretty much verbatim in the ASPN-archived list. I created a python script (proxy-permissioned via Manager) that does return context.owner_info()['id'] Seems like that's the kind of thing that should be in the Zope Book. Where does that method come from? According to the Zope Book, it isn't part of either ObjectManagerItem or PropertyManger... B -- Brian Lalor blalor(a)ithacabands.org

Re: ZopeTime() Error

First of all, please use the zope(a)zope.org mailinglist for Zope related questions, the zope-web list os for Zope.org (website) issues only.

Please use <dtml-var ZopeTime> or <dtml-var name="ZopeTime"> (equivalent) or use <dtml-var "ZopeTime()"> or <dtml-var expr="ZopeTime()"> (again, both equivalent). <dtml-var ZopeTime()> looks up an object with the full name "ZopeTime()" (including the parens) which does not exist. See the Zope Book on Zope.org, chapters on DTML for more info on the difference. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

RE: [Zope] How to check type of variable in DTML
by Schmidt, Allen J. 08 May '02

Nope. That throws a strange error and generates a very odd looking SQL statement which is not valid. Even if I declare it as a list type in the parameters, and use multiple in sqltest, the sql that is rendered tries to escape all the single quotes around each one of the list items and has no idea what to do with the [ ] square brackets. I'll keep banging on it. Thanks -Allen > >From what I have seen, Zope does not do this.

I'll second that. ALL our stuff is in many, many DTML docs and methods. I have been looking over ZPT stuff for a while and trying to make sense of it. One thing that really helped in studying for comparison was creating a new Z Search Method. Choose an existing ZSQL method and then choose to have one rendered in ZPT and then another done with DTML and compare the results. It really helps getting a handle on the concept. My problem is that I do lots of little things with dtml-if statements all over a DTML page to get the results I want. I know it should be done in Python but its hard to switch once your mentality is focused one way. I think our next big project will use ZPT as a test. We'll see....depends on the imposed deadline.

Help!
by Michael 08 May '02

08 May '02

I have 3 different versions of Zope running on my machine. 2.33, 2.41, 2,43. I was working on my site in 2.41 and shut it down and started up 2.33 to export some items. I then shut down 2.33 and fired up 2.41 again and when I logged into the management interface, everything was gone. My site folder, all of my installed products, and the wierdest thing of all, I had to delete the default index_html file in my root folder to get apache to work properly, and it is back! It looks just like I just installed it from the tarball. I checked the 2.43 site and everything in it is gone also. The 2.33 install is still fine. I have backups, but is this normal behavior???

Well that's furry muff, if you don't want to use it. I don't use it because it plays nicely with HTML editors, though (I don't remember the last time I used one, it was bloody ages ago), I use it because it's got excellent seperation between content and presentation. As for XML not being a programming language... ZPT isn't a programming language, it's a templating language. DTML is, well.... to me, DTML occupies some fuzzy ground in the middle where it's got the templating stuff but it's all mixed up with the programming aspect, and it gets easily confused.

by Robert Rottermann 08 May '02

08 May '02

Hi there, I installed ZODBCDB (newest version for 2.4 with Python 2.1) Under Python 2.4 everything works fine. Under 2.51 when I try execute a SQL-Statement like select * from Employees where Name = 'David' I get the following error: ---------------------------------------------------------------------------- ---- Error, sql.error: ('07001', -3010, '[Microsoft][ODBC Microsoft Access Driver] 1 Parameter wurden erwartet, aber es wurden zu wenig Parameter \xfcbergeben.') --> Translation. 1 Parameter was expected, none where given ---------------------------------------------------------------------------- ---- SQL used: select * from Employees where Name = 'David' ---------------------------------------------------------------------------- ---- What is the problem? I am giving a speech on Zope next week and would like to show a DB connection to MS-Access. Therefore help is needed urgently. Thank you very much www.redcor.ch
