[Zope-dev] how to preserv information
Hi,
I'm a new zope programmer.
I created a page which show different
products (from a oracle
database) which can be selected
(products are shoiwn in checkbox
format).
As I have a lot of product I also manage
button ('Next'
and 'previous')
The proble is :
When I select some products from on page
and then I use the
button 'next' or 'pervious I lose the
selected product of the last
page..
Is someone can help me and give me some
solution ??
Thanks
for your help

[Zope-dev] Using Queue within a Zope product
I need to put messages into a queue from within a Zclass, and then get and process them from an external long running process. I have created a class which imports a derivative of queue, the class instantiates a queue as a class object. The idea is that the queue will use a persistent object for the queue (list), and then some external process can also use the same object(list) in its queue processing. Both the zclasses that inherit from this queue and the external process must use the same mutexes... Questions: 1 Should the queue.queue object be made persistent or should we instantiate it with an external list which is the persistent object. Can either of these be done an how. 2. Assuming we can do something like the above what are the considerations wrt package distribution.

Hi Andy,
in this particular case, ZEO is a red herring... In beta 4 (and
curiously, not on the HEAD--I'm sure I'll hear a mea maxima culpa soon
from someone) the base class for the SessionDataManagerTraverser was
made to be a persistent object. Since the base class changed, the ZODB
is now having fits trying to reconcile the change in base classes.
Since the session data manager object gets created automatically by Zope
when it doesn't exist at system startup, you can make a new one (which
inherits from Persistent) by:
1) Edit .../Products/Sessions/SessionDataManager and change the
SessionDataManagerTraverser to not be persistent by duplicating the
class line, commenting out one, and removing the Persistent word from
the other
2) Restart Zope
3) Delete the session data manager from the root object
4) Stop Zope
5) Undo the editing change you did in step 1
6) Restart Zope
The problem will now have been addressed in the ZODB. HOWEVER, since
you mention you are running ZEO, all clients will have to have the same
code base to be able to function. You won't be able to do this without
upgrading all of your code at the same time.

Re: [Zope-dev] Using Queue within a Zope product
I need to put messages into a queue from within a Zclass, and then get and process them from an external long running process. When you say an external long running process, do you mean that you'll want to access them from a separate process via something like XML-RPC? or ZEO? Or HTTP? What is your preferred way to get access to the items in the queue? I have created a class which imports a derivative of queue, the class instantiates a queue as a class object. The idea is that the queue will use a persistent object for the queue (list), and then some external process can also use the same object(list) in its queue processing. Both the zclasses that inherit from this queue and the external process must use the same mutexes... I dont think you mean external process here, I think you might mean something else... two processes can not share the same mutex. Do you maybe mean thread? Questions: 1 Should the queue.queue object be made persistent or should we instantiate it with an external list which is the persistent object. Can either of these be done an how. I think you could probably wrap the Queue class in a persistent wrapper... that'd work. Anything that can be pickled can be made persistent, so as long as the Queue class doesnt have a subobject that can't be pickled, you can make it persistent. You'll need to write a Python product to do so (see the Zope developer's Guide). 2. Assuming we can do something like the above what are the considerations wrt package distribution. None, really... if you intend to share just the class data. If you intend to share exports of instance data (the queues themselves), not much of an issue here either... just need to make sure that each Zope you run on has the Product you create.

Unfortunately, I don't think I can really make it so the transition between 2.4 - 2.5 (forwards and backwards) is completely seamless in all cases all I can do is provide software that helps folks get over their partiuclar hump. I think what might be in order is: - A monkey patch to 2.3 and 2.4 that causes the request to ignore the effects of a bad __before_publishing_traverse__ entry. This will be the prescription for AttributeError: __call__ errors when downgrading from 2.5 to 2.3/2.4.

[Zope-dev] One object where there should be two
I am having a problem with XMLKit. I have the following code in which should
use one disk based DTML Method and produce two slightly different creation
forms, one for XML and one for RSS (a specialization of the XML form):-
manage_addRSSDocumentForm = Globals.DTMLFile('www/addXMLDocument',
globals(), kind='RSS')
manage_addXMLDocumentForm = Globals.DTMLFile('www/addXMLDocument',
globals(), kind='XML')
The problem is that both of my constructors run the RSS form, the XML
version never gets displayed. I have checked the code in __init__ and it
appears fine:-
context.registerClass(
XMLDocument.XMLDocument,
meta_type='XML Document',
permission='Add XML Documents',
icon='www/XMLDocument.gif',
constructors=(
XMLDocument.manage_addXMLDocumentForm,
XMLDocument.manage_addXMLDocument,
),
)
context.registerClass(
XMLDocument.RSSDocument,
meta_type='RSS Document',
permission='Add RSS Documents',
icon='www/RSSDocument.gif',
constructors=(
XMLDocument.manage_addRSSDocumentForm,
XMLDocument.manage_addRSSDocument,
),
)
I've tried just about everything I can think of, can anyone shed any light?
Is this a special rule I have broken?
Thanks.
