[Zope-dev] ZMailIn patch (index 'date' as DateTime object)

2001-11-09 Thread Jean Jordaan 

Hi Andy  all

There I was, trying to select last week's mail messages from
the ZMailInCatalog, when I realized that the 'date' index was
a simple string. 

Here's a patch, adding a property 'datetime', which can be 
used as an index of type DateTime. 

Anything I'm missing here? In particular, I'm not sure I
understand what 'sortableDate' is meant for. It's a string 
like this::

  str('%04d%02d%02d%02d%02d%02d' % (dateTuple[0],dateTuple[1],
  dateTuple[2],dateTuple[3],dateTuple[4],dateTuple[5]))

But it's still a string, and can't be used in comparisons 
with DateTimes. Why not just use 'datetime', also sortable?

Regards,
Jean Jordaan

[Zope-dev] unrestrictedTraverse unable to access the root object

2001-11-09 Thread Johan Carlsson [Torped] 

Hi all,
The collector seems to still be offline?

I just realized that the unrestrictedTraverse returns self
for the empty-string url: ''
I did expect it to return the root object because the empty-string
is equal to the path tuple ('',).

Is there any reason for the current behaviour?
Does anybody know any bad things that might happen if I
change this behaviour?

Best Regards,
Johan Carlsson

 DateTime objects are huge.

Hmm, OK, I'll keep that in mind .. For sorting my mails, though, I'll
stick with the DateTimes. 

It would be cool if ZMailIn was more flexible as to which catalog it
uses and what properties are indexed, without requiring one to hack the
source .. I'll see if I can think of a way to make it so. 

Thanks for the answer,
Jean

[Zope-dev] Zope and python namespaces

2001-11-09 Thread Roch'e Compaan 

I wrote an external method that uses Graphite, Sping and PIL to
generate charts, but I ran into some namespace problems.  Execution
of the external method fails because there is a clash in the namespace
between PIL and Zope.  PIL has a module ImageFile and Zope does as
well.  Even if I insert PIL's path explicitly as the first entry in
the path, Zope's ImageFile is still being used.

How can I resolve this and what is the best strategy to avoid namespace
problems here?

Roché

[Zope-dev] Transaction environment in threaded zope-product

2001-11-09 Thread Christian Theune 

Hi.

I have a zope product, that uses threads, to control programs
running outside zope and doing some async stuff.

What I found is, that i can't do changes from the self-started
thread (ChrisW: that's the problem... ;) ).

But how do I get into a transaction do be able to change things on
persistent objects?

get_transaction().begin() doesn't work, and I don't find any
documentation to get started from ...

plz help me

Christian

You do realise that's pointing a loaded gun at your own head?

 get_transaction().begin() doesn't work, and I don't find any
 documentation to get started from ...

Maybe you're looking for get_transaction().commit()?

But, to be able to see the results in another thread, that thread would probabyl
need to do get_transaction().begin().

Just so you're aware, I think you're wandering through a minefield with this
one...

[Zope-dev] pdf - Files not viewable

2001-11-09 Thread Tim McLaughlin 

This used to work, and I'm vexed as to why it doesn't now.  When PDFs
are uploaded as file objects and then viewed, on IE 5.0+ with Acrobat
Reader, they appear as blank when Acrobat Reader pops up to read them. 
I get no errors on the stupid log, and generally haven't any idea what
the deal is since this used to work.  Did something change in 2.4 that
could have caused File objects to function badly?

Thanks,
Tim

You need a ZODB connection in order to be able to change objects
in the ZODB.

You get one (in your new thread!) by 

from Zope import app

root= app() # the ZODB root object but without 'RequestContainer'

You can now build a new REQUEST object and use BaseRequest.traverse
to reach the object you want (identified by an URL).

Before you change anything, you need to begin a transaction
and finally either commit or abort it.

Use Pythons package feature, i.e. use

import PIL

PIL.ImageFile
