In the example <dtml-in list> <dtml-var foo> </dtml-in> the iteration will change the namespace to that of each sequence-item automatically. So the foo asked for will always be the foo of the current sequence-item. Things like <with sequence-item> or "_['sequence-item']..." are not necessary. If you iteration is by a number of IDs, as your question suggests, though, the example is not enough. When you iterate over a list of IDs, the sequence-item will be an ID (that is a string) and foo will have no meaning (it will throw an AttributeError). There are two way of remediating this: preferrably use objectValues(), like so <dtml-in objectValues> <dtml-var foo> </dtml-in> If you _have_ to use a list of ids, things get more complicated <dtml-in Ids> <dtml-var "_.getitem(_['sequence-item'].foo)"> </dtml-in> (sorry about that) All code is untested, but it should work.

Though I haven't seen any clear statement to confirm this, I believe this is a very large part of DC's decision to release ZEO. By enabling Zope clusters ZEO addresses pragmatically several limitations inherent in the curent state of Zope / Python. As a side effect, redundancy brings with it answers to concerns regarding reliablility, of hardware, if not Zope itself, in a mission critical setting. While some may see throwing hardware at performance / reliability needs, as inelegant at best, to others with hopes of rolling Zope out for the long term, this seems like a perfectly reasonable solution. Python and Zope will continue to improve, and all Zope users will benefit. For now, leveraging commodity priced hardware is actually about as elegant as it gets. So, DC has heard and answered, and Zope is the better for it!

On occassion our visitors will get a timeout when trying to perform a query that is rather large. Is there a way of adjusting the timeout? Or is there something else we can look at doing? DR

Does it checks if an obj as a certain property >(eg aq_parent)? yes, only in pythonish these are called attributes. >Unfortunately it seems not to work. Hm, I tested it. It works for me.

They offer several options above "basic" Zope hosting: * Install your own products (this is their "professional" option). * Add disk space cheaply (they quoted me $0.50/month for each added 10 Mb). * Add domains, mapping them to separate Zope folders, for $10/mo each. > Shell access is welcome, too..

Zope wants to be a long-running process, with significant CPU and RAM requirements; most ISPs don't appreciate you running such a beast, so ask first.

Bill - Are you using the built-in UserFolders that come with Zope or a third party authentication source (or running in 'remote user mode')? If not, is there any part of your code that might be trying to change the AUTHENTICATED_USER in the REQUEST at any point?

calling methods for each object in a list
by Philipp Dunkel 30 Mar '00

30 Mar '00

Hi Zopistas. I have the following problem: I have a form that prints out a list with object-titles and a checkbox next to each of them. All this objects have the same method foo now I want my users to check that objects where the function foo shall be called with. So all checkboxes have the same name and I give a list of ids over: when I do a <dtml-in ids> <dtml-var sequence-item> </dtml-in> it prints out the ids of the checked objects fine, but when I try a <dtml-in ids> <dtml-call "sequence-item.foo"> </dtml-in> he doesn't know sequence-item anymore any ideas?

Bug: thousand_sep does not respect locale
by Dr. Peer Griebel 30 Mar '00

30 Mar '00

Hi, I just found something in DT_Var.py which I mean is a bug. The function thousands_commas uses a hard coded ',' to as thousands delimiter. I think it would be best to use locale.format instead for this purpose. Is there anybody how can incorporate this change into Zope?! One more related question: How can I print the current currency symbol in Zope? I could not access the locale namespace in a dtml method.
