tree doesn't work 4me linux amd win32

I'm a zope newbie. I just installed on a windows 95 box and on a linux 2.0.something but I can't get anything with tree working (other stuff seems ok). Hadars' second sample app doesn't work for me (the tree part produces no output). Even the minimal   doesn't produce output (tried this with the second Habar example after creating the "sub-folders"). I get the same behaviour on windows as linux. I must be doing something wrong. Clues please ? Andy btw: Zope looks really good to me (when I can get over these glitches). --------------------------- Andy Heath, Senior Lecturer a.k.heath(a)shu.ac.uk o Sheffield Hallam University.

I meant to bring this up in my earlier post -- this tag too, is used to simplify what could be a terribly complicated SQL Method given an indeterminate number and list of search criteria. With this tag you can permit an arbitrary arguments to be supplied connected with your predetermined ANDs and ORs This one tag has, in the past, reduced may SQL Methods into one -- natural maintenance savings. --Rob

Absolutely... we ran into some situations where the SQL was so dynamic potential security problems arose. sqltest and sqlvar are designed to reduce that exposure. Additionally, we've found a very common rhythm where a search UI might expose all of a large percentage of the available data elements in the RDBMS. Using sqltest lets the user not specify one or more parameters without a lot of messy  stuff in the SQL Method. --Rob

ZServer is still at alpha 2 so it's premature to focus on things like how it is packaged. I *think* we have all the issues figured out and the next release, perhaps this month, will be a beta1. Until we get into beta, we'll have to hope that someone in the community packages it up as a service. > Now my question. How can I do what I need to do.

One issue off the top of my head is integration with the NT Event Log. --Paul

By moving the "with" statement to enclose it (see line 002), the statement <!--#if "objectValues(... now loops over the objects inside the folder named "subFolder".

Go ahead and ask your questions, the unsuported just means we can't make any guarantees or commit company resources to it, but if your question happens to use Confera as it's basis all the better.

ZServer as a windows NT service?
by Dick Wall 09 Mar '99

09 Mar '99

Hi all, I have been using python for years, and zope for a few months now (lovely), ZServer for weeks, but Windows NT? Not long enough to understand the differences between services and ordinary process (give me a break, I am heavily from a Un*x background) :-). I know when I installed the binary version of Zope on the windows machine here it gave me a service in the services list which I can activate on startup. However, I am betting that this runs the ZopeHTTPServer, not the ZServer which I got as a separate download. I have everything working just lovely with the ZServer now, but it needs to be run as an NT service (and respond to start and stop signals, etc) at which point I freely admit my own inadequacies in this area. Now my question. How can I do what I need to do. Is it simply a case of redirecting a python 'shell' file used by the service to the start.py in the ZServer module, or is there more to it? If it is this simple, which python 'shell' file do I use? If it is not this simple, can someone send me basic instructions on how to do it (why is NT like this - give me an rc.local file any day - I know where I stand with that stuff). Thanks in advance. Dick

Data from forms into a database - how?
by raver＠box.dust.za.net 09 Mar '99

09 Mar '99

Hello! Don't laugh at me - this is probably a very simple thing to do, but as I'm new to zope and can't find description of how this is accomplished I seek your help. I get data out of my database (MySQL) by querying, but how can I have data collected by forms showeled into the database? Appreciate any help I can get! Sture Lygren
