Re: [Zope-dev] Soft links again
Hi Shane, and thanks for Symlink, it's a big step towards solve the problem, but remains an issue... It would be great if the symbolic link could have a different id than the object referenced. But with the __of__ based solution "link.id" is always "referenced_object.id". How this could be done? Okay, I've posted a proof of concept. Please keep in mind that this could be dangerous in terms of security, although I've done a couple of things to make it safer. Also, there's currently a buglet in acquisition that makes it so that you can only perform the actions on the symlink which "anonymous" is allowed to do. http://www.zope.org/Members/hathawsh/Symlink/index_html Shane ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

It would have the ability to act as if it were the object itself while transparently overriding specific attributes. I've pondered creating such a wrapper before, but it crashed so much that I eventually moved on to easier stuff. :-) I think the ability is all there in ExtensionClass, but the details are quite difficult. Shane If I've understanded it right it means I must go to C risking my mental sanity (1), other possibility would be to redesign/reimplement my app (2). Ummhh... I think I'll try 1, it seems more entertaining :), so wish me luck. thanks, david ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] Soft links again
Hi all,
First, I'm using Zope 2.2.1 (Debian package).
I've been trying to implement zope objects that behave like unix soft
links. The message
http://lists.zope.org/pipermail/zope-dev/2000-July/005963.html
by Shane proposes an implementation based in the __of__ method:
class SoftLink (SimpleItem):
def __init__(self, path):
self.path = path
def __of__(self, parent):
ob = self.restrictedTraverse(self.path)
return getattr(ob, 'aq_base', ob).__of__(parent)
but it fails when I try to create an instance:
Traceback (innermost last):
File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish

File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 236, in _getOb
(Object: Traversable)
AttributeError: A00
A little of debug shows that the object has been added (line 249, see below),
the exception raises when it tries to get the object (line 250). The hasattr
function (line 234) returns false but the object has been added (it's in the
__dict__) attribute and its __off__ method is called when the hasattr function
is called.
What I'm doing wrong?
Thanks,
david

class ObjectManager(
...
def _setOb(self, id, object): setattr(self, id, object)
def _delOb(self, id): delattr(self, id)
def _getOb(self, id, default=_marker):
234 if not hasattr(aq_base(self), id):
if default is _marker:
236 raise AttributeError, id
return default
return getattr(self, id)
def _setObject(self,id,object,roles=None,user=None, set_owner=1):
v=self._checkId(id)
if v is not None: id=v
try:t=object.meta_type
except: t=None
self._objects=self._objects+({'id':id,'meta_type':t},)
# Prepare the _p_jar attribute immediately. _getCopy() may need it.
if hasattr(object, '_p_jar'):
object._p_jar = self._p_jar
249 self._setOb(id,object)
250 object=self._getOb(id)

hook or the "linkDate(...)" function.

[Zope-dev] Calendar Tag 0.9.21 released
Hi all, The version 0.9.21 of the calendar tag has been released, it can be downloaded from "http://www.zope.org/Members/jdavid/Calendar". This is a beta version, pre-1.0. If you're aware of any bug or want a *small* change to be done in 1.0 tell me now (hope to release 1.0 and start 1.1.x soon). regards, david ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] CalendarTag, year mode image
Please, look at "http://estce.act.uji.es/calendar.html", there are several proposed images. The only problem I see is when the year mode is selected, since there's more white than black it's not clear which mode is selected. opinions? votes? more suggestions? The calendar mode icons on the Palm are based on the visible structure of the diffent screens (one day, one row of days, a matrix of days). On the newer palms, there is another view (current day and TODO items; a single dot above some lines). To keep in the same "language", I would use a big, black block or circle to show "too many days" to view at once. -- Jens Quade * [EMAIL PROTECTED] * Bonn ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] CalendarTag, year mode image
I've updated the page (http://estce.act.uji.es/calendar.html) following your suggestions, if nobody disagrees I'll release the CalendarTag 0.9.21 with that new look.

You are right, it's dificult to decide wether an icon is selected or not. Of the given proposals, i'd prefer proposal 0, because the other do not have enough "structure". Maybe you could use color, as my Palm does :).

[Zope-dev] CalendarTag, year mode image
Hi all, I'd like to release the 0.9.21 version of the CalendarTag soon, but first I want to change the year mode image, currently it's an "Y" which is not very international, I'd like to see a language neutral image. The interface of the CalendarTag is based in the Palm Pilot, but the Palm III I've here lacks the year mode, I think the Palm VII has. Could somebody send me an international image for the CalendarTag year mode?
