ZPT with Zope 3 queries - repeat over contained items; accessing adapters
by Jim Vine 05 Jul '05

05 Jul '05

Hello, I'm building an application in Zope 3. I have a container object called a PropertyFolder, which holds Property objects. * Repeating over contained items. I'm trying to create a view which displays a list of all the Property objects in a property folder. I've tried doing this as described in the ZPT chapter of the Zope Book (2.6 edition), using a tal:repeat statement, but I can't seem to get it working. Has something changed in Zope 3? I've tried looking in the Zope 3 book, but none of the references to tal:repeat in there seem to be used for this type of thing. * Accessing adapters in ZPT I've created an adapter that provides a method called getStars that can be used on Property objects. Can I access this directly from my ZPT, as I can any other attribute of a property object? At the moment I've got it implemented via a Python view class, so my ZPT accesses it like: <div class="field" tal:content="view/stars" /> but other attributes can be accessed like: <div class="field" tal:content="context/description" /> so I guess I want to be able to do: <div class="field" tal:content="context/getStars" /> and negate the need for the Python View Class, which only says: def stars(self): """Get the stars for the property""" rate = IPropertyRate(self.context) stars = rate.getStars() return stars Thanks in advance for any tips. Thanks, Jim ___________________________________________________________ Yahoo! Messenger - NEW crystal clear PC to PC calling worldwide with voicemail http://uk.messenger.yahoo.com

LDAPUserFolder OLD and Zope 2.5.1 migration to LDAPUserFolder 2.5 and Zope 2.8
by Tim Suter 05 Jul '05

05 Jul '05

I believe it was Jens that gave me the how-to on how to migrate an existing Zope 2.5.1 install using LDAPUserFolder for authentication to Zope 2.8. Below is his response with some of my questions: - Get the latest released LDAPUserFolder version and install it into your new Zope 2.8-based instance I have done this. - Make a backup copy of your old ZODB If you mean the Data.fs, then this is done also. - Log into a 2.5.1-based instance as the emergency user (-> see doc/ SECURITY.txt in your 2.5.1 Zope installation about how to create one) I can't do this part because I was left with no info in regards to what the credentials are as the emergency user. I have located the access file though. Can I delete this file and create a new one documented in SECURITY.txt? - if you don't have a LDAPUserFolder in the Zope root you can skip that and log in as a Manager user from the root user folder The LDAPUserFolder is in the root of the Zope instance and that is the only place it is located. The original acl_user folder is gone leaving only the acl_user folder with the LDAPUserFolder code. - Delete every single LDAPUserFolder instance you have I can do that as long as I am guaranteed that I will be able to log in as the emergency user and as long as when I restore the backed up Data.fs, I will be back to where I started after the migration. - Stop Zope - Copy the Data.fs into your Zope 2.8-based sandbox I am assuming you mean the cleaned up version with no instances of the old LDAPUserFolder. - If you had a LDAPUserFolder at the root, make sure you're set up for an emergency user - Start Zope and log in either as an emergency user or a root user folder manager - Recreate all LDAPUserFolder instances. Just need one, at the root. From there, upon logging in, if you are in our LDAP with the right credentials, then you can manage Zope. Tim

About Zope 2.7.7
by Pascal Peregrina 05 Jul '05

05 Jul '05

Hi, I just finished upgrading our production servers to Zope 2.8.0 (from Zope 2.7.6) Today I noticed that Zope 2.7.7 is under development... and it contains some interesting bug fixes (the one concerning if modified since header handling for example). I guess that these fixes will be included in Zope 2.8.1 right ? Any idea when 2.8.1 may be available ? Thanks.

Pass objects from template to template via HTML forms.
by Negroup - 05 Jul '05

05 Jul '05

Is there some way to pass an object from template A to template B via HTML forms? A <form name="a" action="b" method="post"> <input type="hidden" name="obj" tal:attributes="value here" /> <input type="submit" value="Press" /> </form> B <b tal:content="structure here/REQUEST"></b> Template B prints: form obj '<OrderedFolder instance at 42d9aec0>' I need the object itself, not the string representing the object! I already searched the archive and found a similar request (http://mail.zope.org/pipermail/zope/2003-November/143487.html) but I have not solved the problem. Can you suggest something to try? Thanks

zopectl debug, 2.8.0 local zeo, Data.fs.lock file locking error
by Jeff Kowalczyk 05 Jul '05

05 Jul '05

I am trying to use 'zopectl debug' for the first time with zope-2.8.0, local ZEO setup. It worked fine with zope-2.7.x and earlier. I am now getting a file locking error on Data.fs.lock, which stops the debug initialization at that point. The problem occurs whether I run zopectl as root or as the effective user ('zope') Can anyone familiar with local ZEO debugging on linux spot what might be the cause of the file locking error? Thanks.

I simply need to pass an object directly from one template to another, without intermediate steps (like, copying or creating the object with some manage_*method from a template, read the created object from the other template and then remove the object itself because unuseful..). > > In python it is so immediate: I pass objects between functions via parameters; in zope the most natural way to "simulate" parameters passing from one zpt and another is storing them inside the request object, and thus, using html forms. But for some reasons that I'm missing, it doesn't work! passing objects from one template to another via the REQUEST variable only works while you're in ONE request. otherwise you'll get a string representation as you mentioned. try using the session mechanism instead: http://www.plope.com/Books/2_7Edition/Sessions.stx regards, juergen herrmann _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Juergen Herrmann Weiherweg 10, 93051 Regensburg, Germany Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 ICQ: 27139974 - IRC: #XLhost@quakenet WEB: http://www.XLhost.de _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Juergen Herrmann Weiherweg 10, 93051 Regensburg, Germany Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 ICQ: 27139974 - IRC: #XLhost@quakenet WEB: http://www.XLhost.de

blacklisting referers and/or specific hosts
by Tim Hicks 04 Jul '05

04 Jul '05

Hi, I have a zope site up and running which has recently had a *lots* of hits from a client (or clients) that show referers pointing at various gambling, meds, and loan sites. Requests only come in for the main page, not for the associated images, css, etc that should go with it. The consequence is that my server is working harder to service a client that isn't interested in what it has to say, and my Z2.log is now far less useful to me as all these bogus requests drown out most of the useful information. So, I'm wondering if there's a way to blacklist those clients that I don't like based on host/ip and/or on referer. If I hook into the traversal process in the same way as the virtual host monster objects do, could I check the request against my blacklist and then do a REQUEST.close()? Would that still appear in my logs? Does that even make sense? Is there a HTTP response code that I could return to these clients that would stop them being interested in my server? Any ideas much appreciated. Tim

Apache 2 + Zope can't gzip HTTP response body?
by Daniel Dekany 04 Jul '05

04 Jul '05

Can I use HTTP "Content-Encoding: gzip" for Zope if I use Apache 2? (And should I use gzip content-encoding?) The mod_gzip doesn't work with Apache 2, but instead it has mod_deflate. But mod_deflate can't chose which responses to gzip based on the MIME-type for responses that are coming through ProxyPass/ProxyPassReverse. And with Zope I can't rely on extensions (like .html), just on the MIME-type. Do I think these well? Somebody have solved this (gzip-ing the response bodies)? -- Best regards, Daniel Dekany
