Newbie: uploading file with python script (problem with it)
by Hans de Wit 14 Mar '01

14 Mar '01

Hello, I have a problem uploading files via a form and a python script. The content of the uploaded file after uploading it is only a string, ie the name of the file, not the file itself. I followed the guestbook example of the Zopebook. This is the receiving Python script. # create a unique file id id='entry_%d' % len(context.objectIds()) # create the file afile=context.REQUEST['afilename'] context.manage_addProduct['OFSP'].manage_addFile(id,afile) *** afilename is a field on the form the "sending" form: <form action="addFile"> Add file:<input type="file" name="afilename:string" size="30"><br> <input type="submit" value="upload"> </form> Thanks for any advice Met vriendelijke groeten, Hans de Wit h.de.wit(a)scp.nl

by Greg Green 14 Mar '01

14 Mar '01

Hello, I have tried numerous ways to use the REQUEST and/or the RESPONSE object's in perl methods in Zope without success. I have a Perl Script: arguments: self, REQUEST, RESPONSE Code: return $REQUEST->items(); And i get an error: Error Type: PerlError ErrorValue: Usage: Python::PyObject_GetAttr(o, attrname) at .../perl/Zope.pm line 118. Also I tried an unrestricted Perl script, testperl.pm: --------------------------------------------------------------------- package testperl; require Exporter; @ISA = qw(Exporter); @EXPORT = qw(testit); sub testit { local $self = shift @_; local $REQUEST = shift @_; local $RESPONSE = shift @_; return $REQUEST->items(); } return 1; --------------------------------------------------------------------- This is installed in ZopeBase/Extensions/ZopeExt/testperl.pm When I try it I get: ErrorType: PerlError ErrorValue: Undefined subroutine &ZopeExt::testperl::testit called Please reply to me directly as I am not on the list.

Worldpilot

Hi, out there ! As there seems to be quite some confusion about worlpilot on this list: disclaimer: I'm not involved in any way in wp development or anything the like. But that's what I found out until now: * The site www.wrorldpilot.nl is not the official wp development site, but as there is no other one by now the only one where you're able to download the lateset stable wp. * theres a mailing-list that's quite populated: worldpilot-users(a)lists.sourceforge.net * wp does not work ((at least not well) with Zope > 2.1.6 * Ryan Hughes (wp's developer) is aware of all these shortcomings and wants to resume wp development as soon as he finds time for this. BTW: Check out GUD, looks good ! :-) ta -------------------------------------------------------------------------- smartferret it-consulting Dipl.-Ing. Linzbichler KEG Dipl.-Ing.

Should the use of hasRole() be discouraged?
by Hamish Lawson 14 Mar '01

14 Mar '01

I've read comments from others whereby they've reluctantly been obliged to give users a certain role in order for some products to work, due to a hasRole() call in the product. But why do products call hasRole()? I would have thought that for most cases the proper thing to do was to test for the user having the necessary *permission*; that is, the product shouldn't test for the user having the 'Editor' role, but for having the 'Edit' permission (roles just being a means to simplify the allocation of permissions to users). Or have I missed something? Hamish Lawson ____________________________________________________________ Do You Yahoo!?

FTP File System in Linux!
by Christopher J. Kucera 14 Mar '01

14 Mar '01

Found this on Freshmeat this morning: http://ftpfs.sourceforge.net/ I thought it could possibly be of some import. Basically, it's a kernel module that allows you to mount an FTP session as if it were a filesystem. This could be of great help to people who are trying to get away from using Zope's web interface all the time. I've not actually tried it myself yet, so I can't vouch for it's usefulness, but it should be an interesting project to watch evolve . . . -CJ

user changed to emergency user by accident?
by Joshua 14 Mar '01

14 Mar '01

Hi For some weird reason I suddenly lost all privileges to my zope site and was turned into the emergency user. I cannot create folders or documents. I get an error: Error Type: EmergencyUserCannotOwn Error Value: Objects cannot be owned by the emergency user I am logged in as I always do (root level manager). Why in the world would Zope turn me into the emergency user? I'm not worried about having access. I can make another user I suppose. I just want to fix this problem. Is this a bug? Has anyone experienced anything like this? Joshua

I visited the WorldPilot's site and it seems like it only works with version 2.1.6 of Zope yet I have 2.3.0 Is there any workaround this?

Re: jcNTUserFolder query - authenticating when Zope is not running on DC

Hello, Well, jcNTUserFolder is designed to run on the domain controller. The problem is, I don't know how to *enumerate* users on a distant controller. Also, I don't know how to ask what is the controller of a domain. jcNTUserFolder try to log the user on the computer running Zope. This always succeed when the machine is a domain controller, and the user is in the domain. However, when the machine running zope is not the domain controller, you have to create all the users of that domain in jcNTUserFolder (with the syntax domain\username), and on NT, give those users the right to log on from the network on the machine running Zope. This is difficult to do when you have a lot of users, but sorry, there isn't another way right now, until of course I find a way to enumerate users on a distant controller. regards, jephte.clain(a)univ-reunion.fr

Limiting depth on object creation
by Darin Lee 14 Mar '01

14 Mar '01

Zopisitas, I am building a threaded discussion product which integrates with a news article product I recently wrote. Inside of the article (folderish Zclass) I would like to allow my users to post "reponses." Where I am running into problems is that I would like to limit my "reply-to" depth to only three levels. In other words, I would like to limit a user to only adding three subdirectories in a directory, or 3 folderish objects (responses) beneath a single folderish object (discussion folder). Is there an easy way to check for this? How does one accomplish this in zope? Thanks in advance, -Darin Lee
