Use Page Template to emulate standard_html_footer and header
by Robin Smidsrod 21 Feb '02

21 Feb '02

Is there a way to split up a page template, and define both standard_html_header and footer as page templates which use the other template. I've tried the <metal:block define-macro="header"> and relevant for footer, which should kindof work, but when I try to save the master template it says that some of my tags aren't nested correctly. This kindof makes sense, because I break the nesting to be able to get the "header" of the template. The reason I would like to now this is because I have some DTML documents which need the standard_html_header, and it would be boring to have to duplicate the work I've done in the template into another DTML-document. Any help appreciated... -- Robin

creating instances of products "programmatically"
by greg landrum 21 Feb '02

21 Feb '02

Hi, I've got a Product question that I just haven't been able to answer using the documentation I can find. I've developed a Product called RDJM_JobImpl following the general procedure in the Developers Guide. The product class is defined so: class RDJM_JobImpl(Implicit,Persistent,RoleManager,ObjectManager) I've got enough stuff working so that I can add the product from the manage screen and the guts of the product itself work swimmingly. What I'd really like to be able to do is create instances of this class programmatically (either through scripts or DTML methods or whatever) instead of through the management interface. This I cannot figure out how to do. Pointers to the appropriate documentation would be greatly appreciated. Thanks, -greg -- greg Landrum (greglandrum(a)earthlink.net) Software Carpenter/Computational Chemist

Planning a zope application: maximum size, performance issues
by Scott Wilson 21 Feb '02

21 Feb '02

Hi, I'm currently working on a recruitment processing system that aims to handle both applicant submissions and the management of the process by HR staff. The intention is to use a ZOPE-only solution with Zserver, ZODB (no external DB), Zclasses, and we have a successful prototype running (yay!). An important issue for us is how many applicants a single ZOPE server instance can handle, and what the total number of applications that a single instance can store, without suffering severe performance impairment or instability. This is important for doing forward planning (i.e. how long before the need to buy another server, split up the recruitment campaigns onto separate ZOPE instances etc.) I know its not a simple issue - there are considerations of how large an individual item is, how much processing an application requires once its submitted to the system (quite a bit) and how its all coded (mostly Python scripts called as methods on ZClass isntances) etc. But that said, are there any metrics that can be used to get some ball-park figures? Thanks! ============= Scott Wilson Technical Journalist Centre For Educational Technology Interoperability Standards (CETIS) +44 (0)1248 383645 http://www.cetis.ac.uk
