Is there a limit to the size of the REQUEST space per user and in total. In other words if I have 100 users hit my site can they "use" up the REQUEST space that is available to them??? Dan

'sequence-item' is a "forbidden" variable name in python (bc. of the '-'), so you have to write _['sequence-item'] inside the outer brackets above. cheers, oliver

Well, I tried this again on a different computer with a fresh RedHat 6.2 install, the rest the same as above. Again, I got the same _v_blocks error. Has anyone else seen this? Has anyone gotten TAL working from the standard packages? Any ideas? I really, really want to try TAL! Phil. -- Philip Aylesworth St. Clair College

hi, I have a form and I need the contents, when filled out, to be appended to a coma separated list (line) in a file. What's the best way to do that? Can I do it in the DTML or should it be an External method? j. ...................... ..... Jason C. Leach ... University College of the Cariboo. ..

Building multiple documents from fragments(objects).
by Alan Young 04 Apr '01

04 Apr '01

Hello All, I have some newbie questions. I'm an experienced perl programmer trying to learn Zope/Python and am trying to do something I know must be possible, but am having a hard time wrapping my brain around this new way of doing things. I have a bunch of document fragments with the following structure: /docs fragment1 fragment2 fragment3 ... doc1/ index_html doc2/ index_html Currently, doc1/index_html and doc2/index_html have the following structure: <dtml-var standard_html_header> <h1><dtml-var title_or_id></h1> <div><h3>fragment1 title</h3> <ul> <li><dtml-var fragment1></li> </ul> </div> <div><h3>fragment2 title</h3> <ul> <li><dtml-var fragment2></li> </ul> </div> <div><h3>fragment3 title</h3> <ul> <li><dtml-var fragment3></li> </ul> </div> ... Is there a way that I can do something like this (warning: It's a clunky mix of perl and dtml): for my $f ( qw( fragment1 fragment2 fragment3 ) ) { <div><h3><dtml-var $f-title</h3> <ul> <li><dtml-var $f></li> </ul> </div> } I would prefer to do this entirely in dtml if at all possible (I need to show non-programmers how to do this if I can make it work and they don't wanna know about Python or Perl stuff). Failing that, is there a way I can do this generically enough that a designer could just use a dtml tag and pass the necessary values? Thanks for your input. Alan

How to disable ZODB transaction.
by Juan Carlos Coruña 04 Apr '01

04 Apr '01

Hi zopistas, I'm developing an site that has a few thousands of transactions per day. The site adds and deletes a lot of DTML Documents. The ZODB grows dramatically and when I pack manually the database it consumes a lot of time. Is there a way to disable the transactions persistence in ZODB? When not, how can I invoke a "pack" from a python script to call it periodically with a cron job?

Error: AUTHENTICATED_USER.hasRoles()

Hello, I can't figure out what arguments the hasRoles function takes. I have tried a lot but it all gives an attribute error. I have these 2 roles - StationMan and ChannelMan - and I need to test whether the logged-in user is either one of them. But what arguments must I pass to the function ? -- ************************ Gitte Wange Jensen System Squid Developer MMManager Aps +45 29 72 79 72 gitte(a)mmmanager.org ************************
