New users can't log into the ZMI
by Steph Smith 27 May '04

27 May '04

I'm new to both Zope and Python (not to mention OO programming :), but slowly feeling my way around them :) I have a fresh install of Zope 2.6.4-r1, installed from ebuild. I've read through the "Installing and Starting Zope" chapter in the Zope Book, and also "Getting Started with Zope for Linux and Solaris" article on DevShed. After starting my zope instance, the "Getting Started" guide suggests that the first thing I do is log in to the ZMI as the init user, which I was able to do without any problem. The guide then suggests that I create a new user with manager rights, and to access the ZMI with this user going forward. I go into the acl_users object, and add a new user (with "Manager" role), which appears to be successful. However, when I log out as the init user, and try to log back in as my new user, I am unable to log back in to the ZMI. I have checked the password repeatedly, and that is not the problem. I've tried assigning the "Owner" role to my new user. Still no luck. Created other users. Again, no luck. Unfortunately, nothing is being logged in /var/log/zope/zope-instance, so I have no way of determining whether this is an authentication issue, or a permissions issue, or something else all together. I've looked under the Security tab of the acl_users object, and explicitly set permissions for Managers. I don't think I'm supposed to need to do this, and it didn't help anyway. I have made sure that the 'domain' field for the user has been left empty. Now I'm wondering if there's a step that I've missed, which must be done before I can start adding new users? Or if there is a way to increase what gets logged. I've looked inside the error_log object, but didn't find anything useful. Or perhaps somebody can offer another suggestion/direction to look? I'm very excited about zope (and its forthcoming staging ability). But when first starting out in new territory, its always these little things that trip one up! Thanks in advance! Steph Smith

Quota management under Plone 2 ?
by rherzog 26 May '04

26 May '04

Hi, I am looking at some means to manage a quota for contributors to my Plone 2 site. With my dream product, it would be nice to be able to limit at least at 3 levels for each separate contributor : 1. the total amount of storage used at any moment (it would be handy to have a message sent to the site manager to remind him/her to "compress" the databank if some quota has been reached - there might be room to spare after all...) 2. the maximum size of any individual file (specially "photos" and "videos" as this is what plagues me the most these days - damn those digital cameras and poor snapshot takers ;-) 3. the maximum number of items placed on the site (or currenly "published", as the retired items should not be counted) I found that a "quota folder" has been created a couple of yaers ago. it's version is 0.11 someting. Is this a reasonably stable product to have at least part of what I need for a Plone 2 site ? I am personally not advanced enough in Python to try and cook this on my own furnace ! Thanks for your help and comments. Robert Herzog

FW: Explicit Acquisition within Acquistion.Implicit derived class
by Wyatt Anderson 26 May '04

26 May '04

Anyone familiar with Acquisition specifics in an Acquisition.Implicit Object? I want to be able to dynamically set an attribute (it does Start with an '_' (underscore)) to a value or to explicity say to acquire it from its ancestors. Thanks. Wyatt -----Original Message----- From: Wyatt Anderson [mailto:wyatt95@hotmail.com] Sent: Monday, May 24, 2004 1:42 PM To: 'Wyatt Anderson'; 'zope-dev(a)zope.org' Subject: RE: Explicit Acquisition within Acquistion.Implicit derived class After further review, this strange behavior can happen simply after viewing the object a couple times. It seems erratic at best and obviously is not the behavior I'm after. What am I missing about explicit acquisition? From the Zope Developer's Guide: ------------- Sometimes, you want to dynamically make an implicitly acquiring object acquire explicitly. You can do this by getting the object's aq_explicit attribute. This attribute provides the object with an explicit wrapper that places the original implicit wrapper. ------------- Unfortunately, that's all that is said about aq_explicit. -----Original Message----- From: Wyatt Anderson [mailto:wyatt95@hotmail.com] Sent: Monday, May 24, 2004 1:01 PM To: 'zope-dev(a)zope.org' Subject: Explicit Acquisition within Acquistion.Implicit derived class Hello, I am encountering strange behavior when trying to dynamically set explicit Acquisition within an Acquisition.Implicit object. The strangeness seems to happen when I refresh the product only, but I do not feel certain of this which has me a little nervous. In a Python Product class, named TestAcquisition, I derive from Folder (which in turn gives me Acquistion.Implicit). This class defines an attribute which can dynamically be set to be acquired from nested TestAcquisition objects. In order to do this I test whether the attribute can be acquired (by checking to see if aq_parent has the attribute). In the top-level TestAcquisition object, this attribute should not be acquirable, and thus it will set it self.attribute = 1 In sub-objects of TestAcquisition, by default the attribute will be acquired (which I test and do in manage_afterAdd) by setting self.aq_explicit.attribute = Attribute.Acquired I can dynamically unset and set sub-objects acquisition of this attribute simply by setting self.attribute = 2 or self.aq_explicit.attribute = Attribute.Acquired within the TestAcquistion sub-object. This seems to be working as desired until I refresh the Product, even just simply adding a pdb.set_trace() as the only change. After the refresh all the subobjects that had explicitly been set to acquire the attribute all return the Special Acquisition Object (Acquisition.Acquired) instead of the desired value to be acquired. Is this a bug, something I just have to live with, or am I missing something on acquisition in my product? I'd really like to keep the implicit acquisition and not switch to Acquisition.Explicit. Thanks in advance! Wyatt

Scripts for Login & Logout
by Jonathan Cyr 26 May '04

26 May '04

Hi, I'm in the final stages of writing a web app in Zope. Have a few questions. 1) What's the most elegant way to provide Logout in Zope, I know its been an issue in the past. Anything new? I was using a dummy role and a url like http://dummy:dummy@www.appname.com to move the user to a dummy no-rights account... it worked well until Microsoft patched IE to disregard this syntax. 2) I have "Member" folders in my application. How do I get the TTW Manage Zope behavior of providing a generic login in a shared publicly viewed folder, and on correct login, be conducted right into the Member's space (subfolder). In other words, a member may know their username/password, but not necessarily know their home folder. How would a generic login, focus the user to their member folder. I am using a Zope 2.7, with regular user folders, DTML, and Python Scripts... Not using ZPT, yet. Thanks In Advance, -Jon Cyr cyrj(a)cyr.info
