variables in path expressions

For your consideration: <span tal:omit-tag="" tal:repeat="thepage python:['pageA','pageB']"> <span tal:condition="nocall:here/thepage | nothing" tal:content="structure here/thepage"></span> </span> Basicaly, I want to test if 'pageA' exists, and if so, render it. I'd like to do something like tal:condition="nocall:here/$thepage | nothing", but this doesn't seem to work. Any ideas of how to do this? Thanks, Mark

Call for finnish Zope users, companies and want-to-be users!
by Heimo Laukkanen 09 Nov '02

09 Nov '02

Yes, you. Just you! I know you are there. And you have been hiding long enough! Now it is time to come forward, and meet others alike. Also - if you just happen to know someone using Zope in Finland, please send me an email. Co-operation can be fun and profitable. Even though there is no free beer. --- And in finnish: Käytätkö tai tutkitko Zopea, joko töissä tai omana projektinasi? Nyt olisi hyvä aika tulla ja tavata muita Zopea hyödyntäviä henkilöitä. Järjestetään tapaaminen tässä lähitulevaisuudessa ja katsotaan mitä kaikkea täällä pohjoisessa tehdäänkään. Zope on voimissaan euroopassa ja suomalaisiakin käyttäjiä on varovaisesti arvioiden parikymmentä. Jos enemmän, sen parempi. Heittäkää emailia, niin pistetään keskustelut pystyyn! -huima

TIP: Robots.txt
by BZ 09 Nov '02

09 Nov '02

I have many websites running off of one Zope installation and so it was not too bright to put a robots.txt fill in the Zope root and let all the sites inherit it down. Today, though, I wanted to customize one of them so I did this. # Robots file for <dtml-var absolute_url> User-agent: * Disallow: /Manage Disallow: /acl_users Disallow: /images <dtml-if robot_local> <dtml-var robot_local> </dtml-if> Again, nothing hugely brilliant, but I thought it was interesting enough to publish. I will put it up on Zope.org. Cheers, BZ

dtml-with problem
by Steffen Hausmann 09 Nov '02

09 Nov '02

Hi, I want to display some attributes of an object in a Form. It works fine if I use <dtml-with 20021109202414.0.0739256744506> <dtml-var title> </dtml-with> but if I replace 20021109202414.0.0739256744506 (name of the object) by name (variable containing the name) im gettin a key error. KeyError: dateStart <dtml-var expr="name.title"> doesn't work either. It is used by the userFolder comming with Zope and I can't find any differences to my code. Any Ideas what I'm doing wrong?

Converting an input date string
by McDonnell, Larry 09 Nov '02

09 Nov '02

Hi, How do I convert an input date string "10/22/02" to "2002/10/22" in a date format? The variable I am checking against is in a timestamp format. Even if I time in the string to 2002/10/22, the check is not performed (text vs. timestamp). A pointer would be great, I will still continue to search the archives. Thanks.

Newbie: Confusion at sequence-odd, sequence-even and sequence-start
by Alfredo P. Ricafort 09 Nov '02

09 Nov '02

Hi, I have this code that display images in a 2-column table. The idea is for <dtml-in> to loop inside a folder containing these images. When the counter is odd, an opening <tr> will be inserted; and when a the counter is even a closing </tr> is inserted as well. --------------------- | Image 1 | Image 2 | --------------------- | Image 3 | Image 4 | --------------------- The code is like this: <table width=100% border=1> <dtml-in objectValues> <dtml-if sequence-odd> # Check if the sequence no. is even <tr> and create a row. </dtml-if> <td> # Create a column and <dtml-var sequence-number> insert the image or text </td> <dtml-if sequence-even> # Close the table if even </tr> </dtml-if> </dtml-in> </table> When I ran this code, I noticed that in the first iteration, when the sequence-number is 1, the condition <dtml-if sequence-odd> is not satisfied while the <dtml-if sequence-even> is! So the first few lines of the generated HTML would appear like this. Notice that the 1 column (<td></td>) is created first before the row. <table width=100% border=1> <td> 1 </td> </tr> # <tr> : : So, could somebody explain to me what is going on here. Why can't Zope recognize the first iteration as an odd number, when the value of the sequence-number is 1. And why is the statement <dtml-if sequence-even> is satisfied at this point? Thanks. AL

Import ACL User
by McDonnell, Larry 09 Nov '02

Hi, I have a Zope server dying on me and I will need to move it to another server. I have done this before and rebuilt from scratch. I do not have a large system and the imports are easy to do. BUt adding in all the user is a pain. I have exported them is there a way to import them on a new system.

probably a faq: access INSTANCE_HOME
by Mark McEahern 08 Nov '02

08 Nov '02

Admittedly, I spent 5 minutes searching and no joy... How does one access INSTANCE_HOME in an external method? The logic I need is something like this--I'm just missing the incantation for my fanciful getZopeEnviron. Help? # a fanciful dream... import os def dostuff(self): location = self.getZopeEnviron("INSTANCE_HOME", None) if not location: location = self.getZopeEnviron("SOFTWARE_HOME", None) if not location: raise PukeOla("What the f---?") import_dir = os.path.join(location, "import") # Now we're cooking with fire... Cheers, // m -
