[Zope3-Users] searching content objects on created datetime
Hi, I am trying to search my content objects on their creation datetime. For example, a user can enter From and To dates and I would like to retrieve all content objects based on the date range. I am thinking I should be using a catalog for this and went about creating an adapter for the content I would like to search providing the following interface: class IContentCreated(Interface): contentCreated = Datetime(title=_(u"Content Created Time")) Then I created a catalog with field index named `created` on IContentCreated interface and contentCreated field. But now I am stuck on how to search the catalog based on a date range. I guess I am trying to do something like my_catalog.searchResults( ??? created > fromDate created < toDate ??? ) Or maybe catalog not the way to go and I should be going straight to the objects. Thanks in advance Alen ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Problem: "Could not locate Zope software installation!"
I downloaded ZopeX3-3.0.1 and Zope3.1 (final). The ./configure | make | make install (as root) went without a hitch. However, when I went to make an instance (with either 3.0.1 or 3.1) I got a "Could not locate Zope software installation!" In both cases, I used the default settings (i.e., Zope was made in /usr/local/Zopex/ I used /usr/local/ZopeX3x/bin/mkzopeinstance -u manager:secret ... and got the error message. I've seen this before in the bug track list, but has anyone got a workaround? I'm using Zope on Gentoo Linux (2.6.13-r2 kernel) with python 2.3.5 and and GCC 3.4.4. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Hi Matt. Looks like that might be an omission from the quick start,
and a reasonable one at that. We (Zope 3 devs) need to have a
default story for adapting request to timezone if formlib is to be
part of the trunk (and it is now). Here's a workaround (sorry that
it makes you maybe do more than you should have to do for a "quick
start").
Make a file, maybe called adapters.py in your package, with this in it:
import pytz
from zope import interface, component
from zope.interface.common.idatetime import ITZInfo
from zope.publisher.interfaces.browser import IBrowserRequest
@interface.implementer(ITZinfo)
@component.adapter(IBrowserRequest)
def tzinfo(request):
return pytz.timezone('US/Eastern') # or whatever timezone you wish
I dunno if Benji is having you use zcml yet. If you are, add this to
your zcml:
*Otherwise* try adding this to the end of your file--
component.provideAdapter(tzinfo)
--and make sure you import the adapters file from someplace so that
it will actually run.

[Zope3-Users] benji york's quick_start.txt
Hi,
I'm following Benji's quick_start.txt
(http://www.benjiyork.com/quick_start.txt).
I've followed everything precisly up to the "Adding Menu Entries"
section, at which point
zope3 throws the following error:

TypeError: ('Could not adapt', http://localhost:8080/hello/@@edit.html>, )
I assume this is because I'm using a checkout from the trunk, and
something's borked?
If not, then I assume there is an omission in the quick_start.txt, and
the view class needs to implement IBrowerRequest (or something like
that... not sure!)
Environment:
Ubuntu Linux (Breezy)
Python 2.4.2
Zope3 (svn checkout as persibed by quick_start.txt)
Anyone have the same error or know where I'm going wrong?
I've made sure to check and re-check the code to ensure it matches
that in the quick_start.txt.
cheers,
Matt

[Zope3-Users] Re: event subscribers
Florent, thanks for the thoughts... :) I'm using zope.app.workflow (the X3.0 addon). IRelease is just a content object. I think, just like you mentioned, that I can work my way around it by looking at event.object... Just like you mentioned, and Jim mentioned earlier, I think I was counting on a behavior that mirrored IObjectEvent (like someMethod(obj, event) to be the subscribing method). if I get it working using event.object instead of method(object, event), I might look at hacking out a change, at least to see how far i can get with it, to zope.app.workflow to redispatch, but I don't think I understand the event dispatch machinery well enough yet to know if it's within my grasp. a review of IObjectEvent is in order for me ;) Thanks much!

Re: [Zope3-Users] bug on HP-UX 11.00
I don't know much about HPUX, but one issue that seems to plague a lot of less-frequently-used platforms is stack sizes. For example, for a while in FreeBSD and on MacOS, you needed to explicitly bump up the thread stack size. See doc/PLATFORMS/BSD.txt in the Zope release for an idea about how to do this. - C On Oct 5, 2005, at 10:08 AM, Chris Leonello wrote: I have been successfully running for many months on Windows XP and Mac OS X.
