fsimport, external user folder
by Michael Arndt 03 May '00

03 May '00

Hello together, has someone combined external userfolder an one of the two import methods of zope ? Reason: If i use zope i have a big amount of existing web documents i have to import ( one set of data is about 2 GB no upper limit by data, can only be limited by setting an upper allowed limit ) Does someone know if Frontpage supports WebDAV and can be combined with Zope ? and last Question: Does someone know, what is the design reason to import all Data in the Zope Database and not maintaining pointers to data in any case ? ( Reason: when evaluating i did an import of data of only one user and Zope Database crashed immediatly. Now my situation is somwhat special since not all documentation tends to be 18 GB per user, but i would assume that Documentation Projects tend to grow, so i would assume maintaining references to data is faster ... ?) thanks for your help and answers Micha -- ======================================================== Michael Arndt science + computing gmbh c/o CAE-Systemservice Abt.

Hi, I haven't followed this list for a few months now; but, I thought it would be worthwhile to pass on this link: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.zope.org&outline= Shouldn't an open source project strive to be as standards compliant as possible...? I learned that I was improperly using heading levels from this link (see Outline at bottom of page)... Just trying to help, Pierre

Not logging in - what have I missed?
by Geoff Gardiner 03 May '00

03 May '00

Another couple of simpleton problems, I think. Direct help, and pointers to existing information, will be very welcome. Installation: - Zope 2.1.6 on Win NT4 SP5 - Zope default installation to D: - starting as a service - var directory has Everyone=All permissions 1) Although I can view Ok as Anonymous, I can't get Zope to recognize any username/password combination other than the superuser. I have defined users at the top level and in the folder where my pages are. When I get to a page that requires authentication, only the superuser pair will work. Those from acl_users keep returning the login prompt until it expires. 2) Although I have set the permissions for Anonymous to permit "change Properties" in the folder I continue to get a "manage_Properties" permissions error when I try to exercise this permission. Thank you for any and all clues. Geoff Gardiner

It's an > area of the Zope scope (;-) that I have thought about for a while(storage). I beleive that this tradeoff (transactional integrity vs. efficient writes) would be made irrelevant if the FS in question was either ReiserFS or the IRIX Journalling FS, but I don't really know enough about either to be certain.

Changing index_html method from anoter method
by Pierre Rougier 03 May '00

03 May '00

Hi, This quite the same question than my last one but I may have not been clear...: I want to change the code of my index_html method from another method. I tried with manage_upload... I didn't manage, as I think there is a permission problem (even If I changed the proxy) I tried directly with index_html.raw, I didn't manage I though that a function write_raw() was existing, I didn't find... Do u know how can I do such a thing? Isn't possible to make something like <dtml-var "index_html.raw = new_index_html">... Thanks..... Pierre

SQL information (off topic)
by Morten W. Petersen 03 May '00

03 May '00

I've searched the net numerous times, for some good SQL documentation (specifically advanced tutorials); but I can't seem to find it _anywhere_. This information could probably be useful to a _lot_ of (Zope)people. -Morten ------------------------------------------------------------- How to reply to email: http://home.sol.no/~vidaandr/news/OBSquoting.html (norsk) http://home.sol.no/~vidaandr/news/FAQquoting.html (english) Who is the bigger fool?

global search
by Jonathan Park 03 May '00

03 May '00

Good morning everyone! This is just an experiment I was trying to figure out how I would make my search using search interface global meaning it would check under squish sites under different folders. I tried using or statements, also tried cataloging just a squish site but the results I got were not accurate. Just curious. :) Is possible? Right? Anything is possible, is just matter of figuring out HOW? :) Thank you! -jon I wish all of you a great day!

Help please = mxDateTime needed in Zope
by Jason Cunliffe 03 May '00

03 May '00

Hello An intermodal transport project I am working on needs more advanced DateTime tools than native Zope or the [lovely] CalendarTag product offer. I've looked at the Python package mxDateTime http://starship.python.net/~lemburg/mxDateTime.html ...and YES it's just what we want. Key features we like are: - clean consistent syntax, - the facility for datetime arithmetic - all-in-one precision for timestamping anything. Our application requires a framework for participants in intermodal transport chains to search and negociate multiple transport connections [truck and ship mainly]. Becuase of the interdependancies it is necesasary to frequently iterate between multiple schedules from multiple prespectives. This demands on the fly datetime arithemetic. Q: How can we get _FULL_ access to all those features/functions/paramters/etc in Zope via DTML or otherwise? >>>Strategic and technical advice is needed... PythonExternal Methods vs. ZopeProduct vs. ??? We've tried wrapping some test functions from mxDateTime as PythonExternal methods, but [argghh] cannot pass parameters to them. Works ok in Python but not in Zope 8-( Is it possible to pass parameters to and from DTML to External Python Methods? If so How.. My dream is that mxDateTime becomes part of standard Python and thus Zope. But I confess I really do not undersatnd the realtionship between modules in the Python directory and what is available to call from Zope. Help. Really hoping there is a good solution Thanks in advance. - Jason Cunliffe ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director
