External Editor 0.8 breaks ZMI for External Method
by David Chandek-Stark 03 Nov '04

03 Nov '04

I have e-mailed the developer about this, but have gotten no response. After adding an external method in the ZMI, I get errors when attempting to revisit the method. This makes it impossible to run external methods via the 'Test' tab. Zope 2.6.2/Python 2.1.3 Zope 2.7.0/Python 2.3.2 Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module App.special_dtml, line 174, in _exec Module Shared.DC.Scripts.Bindings, line 266, in __render_with_namespace__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module App.special_dtml, line 174, in _exec Module DocumentTemplate.DT_With, line 76, in render Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: this Module <string>, line 0, in ?

Access to global methods in product creation forms
by Marco Bizzarri 02 Nov '04

02 Nov '04

Hi all. I'm sorry, I've already posted this message on zope-dev, realizing that it was not the right place. I would like to use a global method in the add form of a product. I've declared the method in the methods dictionary of the package. However, when I try to add the product, I receive an unauthorized exception. The environment is python2.3.4 and zope 2.7.3, running on Debian GNU/Linux. I've attached a simple test product showing the problem. Thanks you in advance for your support. Regards Marco

Number of Zope process on Linux
by Ulrich Wisser 02 Nov '04

02 Nov '04

Hi, I am running Zope on Linux (RH 9). Performance is not that great (to say the least). I can see only two Zope processes and only one seems to use any cpu time. Is that supposed to be like that? Should I do anything about it? If so, what do I need to do? I realize that this has been discussed before, I just couldn't find the thread in the archives or through Google. TIA Ulrich

Migrating to GRUF sensible, possible?
by Mark Barratt 02 Nov '04

02 Nov '04

I have a Zope site with an (out of the box) acl_users in its root containing lots of (700+) users, and a Plone site a few layers down within the site, which currently inherits user data from the acl_users in the root. Either using GroupUserFolder (GRUF) at the root of my site and getting the existing acl_users into it, or setting up GRUF in Plone so it inherits users from the ordinary acl_users above it would make it possible to administer users sensibly in both the Zope-only and Plone parts of my site. Plone (2.04) claims GRUF is optional, but I don't think it is. But I can't see how to do either task, though I have read the book, googled around, etc. Is what I want to do sensible? Possible? Thanks for any help or pointers -- Mark Barratt

Storing callable references in the ZODB
by Terry Hancock 02 Nov '04

02 Nov '04

I recently discovered that the ZODB (possibly newly, or maybe I just haven't noticed this problem before) will not allow a persistent instance to have an attribute assigned to it which is a function or a method. In other words, the following is not allowed: class MyZopeObj(Persistent,...): def __init__(self, callme=None): self.func = callme although you can do this: class MyZopeObj(Persistent,...): callme = ... (e.g. archived message http://gossamer-threads.com/lists/zope/users/168215 ) I have a situation in which I need to find a way to reference a callable object (doesn't strictly have to be a method/function, but I do want to call it), and I'm having a little difficulty getting it to fail for me so that I can test some workaround ideas I have. Here's what I'm doing so far. I'm using Python 2.3.4 and Zope 2.7.0: import Zope Zope.configure('/location/of/zope.conf') app = Zope.app() app.objectIds() # This displays the contents of my root folder in my # local Zope instance. So far so good. # make a sandbox folder to play with app.manage_addFolder('test_perscall') f = app.test_perscall # define a function to evilly reference from ZODB: def spam(a): return a # OK, why doesn't *this* fail? f.spam = spam #(Surely this is storing the function # reference in the ZODB?) # Maybe I need to specifically init this reference in # a persistent object? Let's try that . . . from Persistence import Persistent from OFS import Folder class WCall(Persistent, Folder): """ Test object to hold a method in it's instance. """ def __init__(self, id, title=''): self.id = id self.title = title self.spam = spam ob = WCall('wcall', 'Test callable object instance method') f._setOb('wcall', ob) # WHAT?! *Still* no failure? I figure I must need to get a ZODB commit to happen or something to make my "unpickleable" error come up, but how do I make that happen from the Python interpreter command line? Any comments would be much appreciated. What I need to do is get the error to come up reliably so that I know I understand its limits, and then I need to test my workaround (which is to trace the function's module and name, store the result in a persistent callable object wrapper which can retrieve the function and call it at need). And of course, I have to make it work without error for my workaround code. TIA & Cheers, Terry -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com

restore acl_users after removal
by Jonas Meurer 01 Nov '04

01 Nov '04

hello, sorry for the stupid question, but ... i removed my acl_users folder, and now need to restore it. there's no real problem with the lost data, but i'm not able to login into zope any longer in any way. even emergency user and ftp login don't work any more. is there any way to access the zope file hierarchy for placing a new acl_users folder there? otherwise ... does this mean, that there's no way any longer to access the data in zope? bye jonas

Zope Book?
by Shane Graber 01 Nov '04

01 Nov '04

I'm slowly learning Zope and have read through the Zope Book 2.6 that's available from zope.org. I am also interested in purchasing an additional book to better understand using Zope. Does anyone have any recommendations? I've been using Zope for a couple months now (primarily for Plone). I'm fairly low on the learning curve and would like to find a good overall book on the subject. Does anyone have any recommendations? Thanks in advance, Shane Graber

[ANN] TextIndexNG 2.1.1 released
by Andreas Jung 01 Nov '04

01 Nov '04

I am pleased to announce the release of TextIndexNG 2.1.1 Changes in 2.1.1: - improved encoding handling in Winword converter (patch by Osma Suomine) - TXNG tries to guess the mimetype as fallback for files with mimetype application/octet-stream files (patch by Osma Suomine) - improved handling of Searchable + enabled converters (patch by Osma Suomine) - added manage_cleanVocabulary() to clean up the vocabulary from no longer existing terms - a phrase search no longer raises an exception if the phrase contains the words 'and', 'or', 'not' or 'near'. This means you can use these terms safely within a phrase search. TextIndexNG homepage: http://www.zopyx.com/OpenSource/TextIndexNG

RE: [Zope] change user password
by Marinussen, M.J. (Ria) 01 Nov '04

01 Nov '04

Hi Eddy, I had a similar question a while ago, and with some help from this list I managed to produce a pythonscript to do this very thing. People who are logged on can change their own password with it. You need a form in which they can type the new password (and confirm it). Processing can be done with this script: ========= # Parameter List: new_password, new_password_confirm ==== # get name, roles and domain from currently logged on user user = _.SecurityGetUser() name = user.getUserName() roles = user.getRoles() domains = user.getDomains() # Test whether the user of this script is logged on # if user is not logged in, do nothing, else change password. if name == "Anonymous User": return else: # get userfolder userfolder = getattr(context, 'acl_users') # take password and confirmation from password and info from logged on user and put in dictionary user_info = { 'name' : name, 'password' : new_password, 'confirm' : new_password_confirm, 'roles' : roles, 'domains' : domains } userfolder.manage_users(submit='Change', REQUEST=user_info) return ============== Good luck with it!
