Storing files externally
by Alexander Limi 18 Dec '99

18 Dec '99

Zopistas, I'm trying to store files that are submitted from a form on the local filesystem, and not in the ZODB. First, I thought I could use the LocalFS product, but this is read only, so no dice. Then I tried to implement the things I found in the "Howto store files externally"-howto. I'm almost there (after some fiddling around, the howto is a bit lacking) but I get errors. When I try to add an object of the class "myFileClass", I get the following: "Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: cookId" The external method "cookId" is located in the ZClass. Traceback below. Shouldn't it be easy to store files outside the ZODB? I find these methods a bit cumbersome. Alexander Limi. http://mp3.no Traceback (innermost last): File D:\Programs\Zope\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\Programs\Zope\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\Programs\Zope\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: RoleManager) File D:\Programs\Zope\lib\python\ZPublisher\Publish.py, line 165, in publish File D:\Programs\Zope\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: myFileClass_add) File D:\Programs\Zope\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: myFileClass_add) File D:\Programs\Zope\lib\python\OFS\DTMLMethod.py, line 145, in __call__ (Object: myFileClass_add) File D:\Programs\Zope\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: myFileClass_add) File D:\Programs\Zope\lib\python\DocumentTemplate\DT_With.py, line 133, in render (Object: myFileClass.createInObjectManager(cookId(REQUEST['file']), REQUEST)) File D:\Programs\Zope\lib\python\DocumentTemplate\DT_Util.py, line 335, in eval (Object: myFileClass.createInObjectManager(cookId(REQUEST['file']), REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

Authentication with IIS
by Ava 18 Dec '99

18 Dec '99

Hello, This question has been asked several times already, and the answer is always the same: Q: How to to interface Zope with IIS A: turn off challenge/response authentication and turn on basic authentication for Zope to handle authentication *BUT* I want IIS to handle authentication, and give Zope the user's name through REMOTE_USER. It seems not to be possible. Has anyone managed to do that? Here, everyone who is logged on the NT Domain is already authenticated when they browse the intranet. But I don't know how to get this information from Zope. *Please* give me any clue concerning this. <PROMISE> If someone can point me in the right direction, I can even start to write some code because my boss is not willing to use basic authentication. </PROMISE> Regards, Jephte CLAIN minf7(a)educ.univ-reunion.fr PS: please CC any answer to minf7(a)educ.univ-reunion.fr

Hi, Zope currently tweaks all HTML documents before delivering it. It inserts a <base href="..."> line in all HTML documents delivered. How can I turn this feature off for specific cases? regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

RE: [Zope] Acquisition problem - please help

ok, now I have questions. 1. If methodX writes new values to these properties, which object gets modified? 2. Since everything is off of [one] can't I get everything through proper structuring of the url? 3. Isn't security (permissions) acquired? (see previous post about structuring large projects) 4. Can I circumvent security by structuring my url to acquire methodX from another object?

But, as Emacs has transparent support for editing by FTP, you should still be able to use all your traditional Emacs tools -- PLUS, with a bit of conniving, use CVS with Emacs' built-in vc support. Also aren't there are few plugins or something that will store the Zope objects in a standard filesystem instead of the single database file? I have no idea what it uses as the representation for these objects, however it might be worth your time to investigate and see if they are stored in plain text native form. -- John Goerzen Linux, Unix consulting & programming jgoerzen(a)complete.org | Developer, Debian GNU/Linux (Free powerful OS upgrade) www.debian.org | ----------------------------------------------------------------------------+ via Remote

Jolt
by Rob Page 17 Dec '99

17 Dec '99

Hello everyone: I just received a flyer from Software Development Magazine soliciting input for the 2000 Jolt awards. Essentially, the Jolt award is given to various products and technologies that make development easier. I believe passionately that Zope fits that bill. However, Digital Creations will NOT be nominating Zope ourselves. If you as a Zope community think Zope is a Good Thing, I'd encourage you to visit Software Development magazine at www.sdmagazine.com and the Jolt page at http://www.sdmagazine.com/sdonline/fr_jolt.html Go Zope! --Rob -- Rob Page V: 540.371.6909 Digital Creations, Inc.

Acquisition problem - please help
by Dave Parker 17 Dec '99

17 Dec '99

If I have a folder structure like this: first second third fourth fifth and first defines a property X and third defines a property X (and nothing else defines proprty X) an first defines a method M And I do http://host/first/second/third/fourth/fifth What value of X would a method M see? The value first set or the value third set? What I'm seeing is this: with http://host/first/second/third, M sees the value that third set with http://host/first/second/third/fourth/fifth, M sees the value that first set I am using "Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2) " Is this what is supposed to happen, or is this a bug that was fixed? I *think* I had it working such that M saw third's value at one point, then I changed the name of the property in question (and all the methods that reference it to reflect that). Now I see what I described above. If this is a bug, is there a work around? Desperate!

ZOracleDA periodically drops connections, please help
by Roman Milner 17 Dec '99

17 Dec '99

Hello. We are about to go live with a new Zope based site but we are having a frustrating problem. Periodically, we lose all of our oracle connections. Our queries start to return oci errors stating that the zsql method is not connected to a database. Sometimes this causes ZServer/python to crash, other times they are still running. In all cases restarting zserver fixes the problem. We have ZServer configured to run pcgi only. Apache also runs and delivers content via pcgi. Our Zope server runs on a redhat 6.2 machine. We have the Oracle DA installed on that machine. Our Oracle server runs on a Sun box. When ZOracleDA loses all of its connections, we can still communicate with the oracle server fine via sqlplus. Any help is greatly appreciated. ^Roman

alot of general dc, zope, public relations questions
by alan runyan 17 Dec '99

what does digicool offer for commercial products to zope? is beehive, code-it, and digital garage selling or making digicool of 'third party' products that may be of use and bought commercially? zeo is the only product I can find listed on digicools site. how about commercial support for zope? by the hour? what if i just wanna buy chunks of functionality from you and hook it onto zope? I see database adapters for 'high-end' databases such as Oracle (8i?), Sybase, and heard DB2 is in works... what about extra pre-built functionality that exploits the data in these databases? does large commercial companies like ishophere.com d/l community products and install them and use them internally? use them in production? what about everyone else? currently I'm looking for workflows inside an application server -> pre-built: author->editor->publisher workflow but something like siteserver w/ the transaction pipeline- where i can arrange around the 'workflow' of web content. here is what i've come up w/ in few words: spectra (lots of pre-built) has lots of workflows looks like what I want- but it runs on coldfusion :(. vignette has workflows + oodles of other functionality you didnt know you needed and where too stupid to ask (? impression from what little i've read). frontier is complete customized user-talk scripting language- contains few work flow products but it was mentioned somewhere you could custom build them (i couldnt imagine having the option of custom building that). then we have zope, suppose to have a product (?) of some kind coming out soon (but no specifics) and it appears from digicool web site and one time I asked them what they sold they mentioend 'bug collector' and zTables, any ideas of putting that up on your web site? (too much to maintain)?. but there is no formal writings on the web site that digicool would sell you anything except consulting services and training. another huge criteria is that I'm running the catalog on siteserver currently.. but want to mix in zope as content management (this sounds like perfect application for zope). but Zope cant be used w/ ASP (?is this TRUELY impossible?!. I dont know how it would happen, but i believe a solution must be possible) - which instantly kills it and pretty much every other product - I've looked at: except frontier and maybe vignette (i dont know tcl and alot more developers are geeked up other python than tcl). anyway: I've shown some developers Zope and most can not get past the web site --zope.org attention-- (zope.org - i personally like it.. although its getting old, visiting it everyday 8) design (mix of fonts, unsexy graphics, poor navigation -> please make Browse the DTML Reference online here. abit more obvious (documentation page) this should be accented w/ a graphic or much more pronounced text like the .tgz) --/zope.org attention-- and the digicool.com web site only speaks of ZEO, and some open source pdfs, ang lots of press releases. NOTE: I'm sure you would rather spend time developing Zope than the website advertising zope.. but it needs to happen for marketing purposes. not HUGE, simple and slick - roxen has a very nice web site. Its just Zope doesnt seem like a commercial viability. does anyone else get that impression? anyway- where is Zope going? can we look forward to y2k as the year for 3rd party zope support? w/ digicool putting their seal of approval on canned products? people running Mozilla to interface into 'raw zope environment'? pythonmethods are incredibly neat- now that they are over @ D.C., any news on import :) btw: is there anything on other application servers ANYWHERE AS COOL as pythonmethods? or even pluggable brains?? (this is marketing genius term, btw) or zClasses?!?! how about cheap (?) or not-so-cheap prebuilt ready-to-roll products for zope? I want to express my utter amazement and appreciation to the Digital Creations programming team for coming up with this gem. once its abit more polished - i couldnt imagine it NOT being embraced by a majority of web development houses. and Ive yet to see any performance numbers? I dont know much about benchmarking zope- I have some webload software at work where i can get some performance numbers and post them back to the web site. I know that statistics can be bent to speak any 'truth' but this is only way I know to see how well zope does do in artifically 'stressed environment' - I work w/ a client that get ~10-15 million requests a day, I just dont think zope could keep up w/ that.. I'm most likely very wrong.. but you wouldnt know it by looking on the web site, honestly). I would imagine ishophere ran ~1 million requests/day - its not running too terribly many requests directly through, no? please make zope sexy so my friends and the world will like it. Amos definetly sex'd up Zope w/ his article at xml.com cheers, alan runyaga(a)thisbox.com p.s. if I'm out of line, by being so critical, shoot me. but these issues were raised by many people over my reign of advocacy at work and these are real world gripes - I've encountered. p.p.s. are you going to make all/some/most python conference zope-based material and lectures available over the internet?
