Zope 2.3.1 Catalog is there a bad bug in this?
by Max M 02 May '01

02 May '01

I have upgraded Zope from an older version to 2.3.1 and I get this error when searching for a known item:: Error Type: KeyError Error Value: 43 It comes when using the code:: <dtml-var "Catalog.getpath(data_record_id_)"> Is this due to a Catalog bug in 2.3.1 ??? (I'd rather want to avoid upgrading to 2.3.2 as I have to travel to get to the site with the installation.) Regards Max M Max M. W. Rasmussen, Denmark.

Cool! I can't wait to see the PDF stuffs. You might want to make the id's randomly generated and sort by titles, though. Also, I got a Zope error from the add button after previewing the created card. Apparently, the form on the preview page fails to pass REQUEST['id'] to whatever method the add button is invoking. I'd like to try it here. Let us know when you have a download URL. Troy It's so Exciting(TM) to see all the new announcements recently: Zope Book, French Zope Book, This, and the audio product.

[Ann] emulateRedirect: emulates redirection inside Zope
by Dieter Maurer 02 May '01

02 May '01

The common task: A user fills a form and submits it. The submitted data is checked and if problems are detected, the user gets its original form together with a problem indication *AND* his already filled in data. is not yet well supported. A redirection to the form suffers from browser differences in the handling of the old request data and the difficulty to add all of them into the redirected URL. Presenting the form without redirection is possible but has several caveats: Side effects caused before the problem has been detected are difficult to discard. The 'base' used by the browser for URL resolution may become wrong, seriously confusing the browser and/or Zope. The small External Method 'emulateRedirect' emulates a redirect without an extra interaction with the browser. It resets the REQUEST parameters such that they get the same values as for a direct traversal to the redirected object. Furthermore, it sets the 'base' tag used by the browser for resolution of relative URL such that relative references from the redirected to object become correct. 'emulateRedirect' provides control over the transaction ('abort', 'commit', 'keep'). 'emulateRedirect' works for Zope 2.3. It may work with Zope 2.2. As it uses undocumented Zope publishing features, it may break with any new Zope version. More information and download via: URL:http://www.dieter.handshake.de/pyprojects/zope Dieter

This tells zope to allow access to > subobjects TTW which is prohibited by default. I assume you mean like this: class A( OFS.ObjectManager.ObjectManager, OFS.PropertyManager.PropertyManager, Acquisition.Implicit, Persistent, AccessControl.Role.RoleManager, OFS.SimpleItem.Item, ): __allow_access_to_unprotected_subobjects__ = 1 I also, just for paranoia sake, added it before Class A is defined as well as Class B. This is the result of this attempt: Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct. Traceback (innermost last): File /usr/local/Zope-2.3.0/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/Zope-2.3.0/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope-2.3.0/lib/python/ZPublisher/Publish.py, line 162, in publish File /usr/local/Zope-2.3.0/lib/python/ZPublisher/BaseRequest.py, line 460, in traverse File /usr/local/Zope-2.3.0/lib/python/ZPublisher/HTTPResponse.py, line 589, in unauthorized Unauthorized: (see above) Last time I checked, my login worked. :) Jason ____________________________________________________________________ Get free email and a permanent address at http://www.netaddress.com/?N=1

Re: [Zope] executing dynamically generated code (eval)?

Someone else has had a similar need than you may have. And he announced an extension "dtml-eval" in the mailing lists. It can be quite dangerous. Of course, it did not make it in the Zope core and I never looked at it more closely (I would use a special purpose External Method for these cases). You may find the announcement via the searchable list archives. Dieter

Product Creation and Permission
by Jason Joy 02 May '01

02 May '01

Hey there, I have a question regarding the use of permissions in Classes, regarding the creation of user-made Products for Zope. The product that I have is made from 2 classes, which for this example I will call classes A and B. From the management screen of Class A after you create a instance of it in Zope, it shows a list from a external database of instances of B. B does not get into the Zope Database at all. A's code has been modified in the manage_menu system such that it can add and subtract instances of B from the external database. It does this just fine. When selecting a instance of B (let's call it C), from the management menu of A, I keep getting asked to enter my password and can never get in, eventually getting it to say that I don't have permission to manage it or view it. I tried adding: security = ClassSecurityInfo() security.declareObjectPublic() security.setDefaultAccess('allow') security.__allow_access_to_unprotected_subobjects__ = 1 ... but it seemed to only grant me access to the index_html, bouncing me down to a lower level other than management. I think the problem is that Zope doesn't see B very well and I need to tell it how to manage it. Does anyone have any ideas how I can take this B object and give it access privledges so that I can manage it? I tried tinkering with __ac_permissions__ but I got locked out even further, not even index_html would come up. :) Any thoughts? Thanks.

Error on Zope download page
by Jerome Alet 02 May '01

02 May '01

Hi, Don't know if this is an error or not, here's what you can read from Zope's download page: Download Zope 2.3.2 the current stable release. Download Zope 2.3.2b2 the current development release. IMHO the devel release should have a version number greater than the stable one, or else I have misunderstood something about developpment for many years now ;-) bye, Jerome Alet - alet(a)unice.fr - http://cortex.unice.fr/~jerome Fac de Medecine de Nice http://wwwmed.unice.fr Tel: (+33) 4 93 37 76 30 Fax: (+33) 4 93 53 15 15 28 Avenue de Valombrose - 06107 NICE Cedex 2 - FRANCE
