"dtml-with" is a tool for putting names on the namespace stack, which is critical for DTML, since the namespace stack is the source of all names. Python, on the other hand, doesn't use DTML namespaces, although it can manipulate them like any other data structure. It doesn't need them, since it can easily create a local variable. Example: <dtml-with expr="foo.bar.controller()"><dtml-var x><dtml-var y></dtml-with> This really means "put 'foo.bar.controller()' on the namespace stack, ask the namespace stack for 'x' and 'y', then pop the stack, but the person who wrote it was probably thinking "get 'x' and 'y' from foo.bar.controller()". In this case, the following Python works: fbc = foo.bar.controller() print fbc.x print fbc.y Cheers, Evan @ digicool & 4-am

I remember, this have been a bug with some Zope version (search the searchable list archive). It should be fixed in the current Zope version. Dieter

Python script and dtml-with
by Farrell, Troy 28 Feb '01

28 Feb '01

I'm not explicitly having a problem, but I would like an explanation. I understand the usefullness of dtml-with in dtml. I was converting some dtml methods to python scripts and I ran across a dtml-with. Is there an equivalent for python scripts? If so, great. If not, please explain why it is not needed. Thanks in advance. Troy

Zope is able to get authentication information from the "REMOTE_USER" request member. You may use a SiteAccess AccessRule in your root folder to copy "LOGON_USER" into "REMOTE_USER". There is a HowTo on Zope.org about SiteAccess use for such purposes. Dieter

I would leave it there (or put it there, if not yet there). Data.fs might grow in principle to 200 GB, but I think of this as a horror szenario. This huge file would be in a single partition (I doubt, Unix supports files spread over several partitions). Doubt that you have such large partitions. When Zope starts, it builds an index for "Data.fs". While the index is much smaller than the file itself, it still will be huge and it is held in memory. Do not do this! My confidence in ZCatalog is limited, too. You have to carefully choose the commit granularity. I, definitely, would go for a standard database solution and use Zopes excellent database integration to interface with the data in the database. Dieter

You the the searchable archives hosted by NIP (found via zope.org)? With them, you may not need to download the archiv files themselves. Dieter
