installing 2.4.0b3 from source confusion
by Romain Slootmaekers 07 Jul '01

07 Jul '01

Yo, dudes, I downloaded the 2.4.0b3 tarball and in the README it states: '''Important This release requires Python 1.5.2. ''' clear enough, but the doc/INSTALL.txt states: ''' Important notes ZOPE 2.4 REQUIRES PYTHON 2.1! See CHANGES.txt for important notes on Zope 2.4. ''' This simple person is somewhat confused.... so what do I acutally need to build it, and to run it. TIA, Sloot.

Problem starting Zope
by Jimmie Houchin 07 Jul '01

07 Jul '01

Hello, After messing around for a long time, I am finally beginning to develop my website. :) I am having problems starting Zope. I've never had problems starting Zope. RH 7.1 I have an updated cvs Zope installed. I have an updated cvs Python installed. It is the cvs Python which is called on the commandline or via /usr/local/bin/python. Installing Zope via wo_pcgi.py and then starting Zope via ./z2.py gives me this: the -h output ... -W port The WebDAV: command not found ./z2.py: line 288: syntax error near unexpected token `sys.path.insert(0,' ./z2.py: line 288: ` sys.path.insert(0, '%s/lib/python' % swhome)' I don't know if I've encountered a bug or did something wrong. Any suggestions appreciated. Thanks, Jimmie Houchin

Zopistas, Please support or denounce this proposal. Integrated HTTPS support in Zope would be really nice IMHO. http://dev.zope.org/Wikis/DevSite/Proposals/ZServerSSLIntegration Shane

ANN: Proposal for Object Variations
by Myroslav.Opyr＠prosolis.com.ua 06 Jul '01

06 Jul '01

Hi, I was thinking a lot at the problem and finally posted draft of proposal on: http://dev.zope.org/Wikis/DevSite/Proposals/ObjectVariations It have to aid in solving different problems. The main problem which pushed me to create this proposal is internationalization of content (especially images). Then I tried to generalize the problem and the Proposal is the result. I do not know all details about current Zope internals and this is why Risk Factors, Scope and Deliverables are in preliminary state. I ask you for review and comments, Thank you, Myroslav Opyr

proxy roles dont jive w/ new security model
by alan runyan 06 Jul '01

06 Jul '01

ok. thanks for a nudge from Martijn I whipped out the trusty debugger and confirmed my worse fears. I have a DTML Method that is a view of a object. I'm using CMF and dont want the person to have to log in to submit content. so what I did was.. say ok. I will create 2 Script (Pythons) that are Proxied at a Management Role, A) creates a new content object, then displays the edit_form, B) submits the edit_form and updates the new instances ;). This is a valid use-case of the CMF. How I think this should be done is creating a PUBLIC user where unreviewed objects go, when they are submitted they are set to review_status of pending. when they are published they are moved into another folder. My Script (Python) -- which is Proxied w/ all roles: creates the new object and then calls a method, getEditView (which is accessible by Public) on my instance, which returns the edit_form, DTML Method called with the instance as the client and the current REQUEST. Now when this DTML Method is called it gets a new SecurityContext. and the new SecurityContext doesnt care about my Proxied roles. (it takes in 0 consideration of this, and this should be noted in the developer guide). Because the Context only cares about *who is calling*, which isnt the Proxy role but the actual user, Anonymous User. ** Thus when its rendering the DTML Method its rendering as Anonymous not as my Proxied Script (Python) and when it hits a this() it horks with a Not Authorized.** <- I'm quite sure how True this is. It appears that when i'm going through the security machinery the 'anExecutableObject' (which is the DTML Method) *has* my proxies roles. BTW: I cant call manage_proxy on the DTML Method, because that also only cares about *who is calling* and the Anonymous Role doesnt do much good for me (if I try 'Manager' or something it correctly complains that I do not have that proxy role). It appears that my DTML Method needs a _customSecurityPolicy. It seems the publishing machinery publishes: Script (Python), then MyDTMLMethod, then the header that MyDTMLMethod uses. do I need a customSecurityPolicy to attach to my DTMLMethods so that they can run in the same security context (which I would like to be, God -- remember they are submitting to a Script(Python) which is doing all the heavy lifting, the rendering is being returned by the Script(Python), so it would be fine if I had a "lets this Publishing Event occur as God" Q: when my header says _.hasattr(this(), 'someAttr') <- this() is the dtml_method(client, request) client reference, correct? this has caused me very much heartache. ;( and emotional damage ;'( I'm very confused and discourgaged right now. If I told you how long i've spent on this you would cringe. My end goal is to make a CMF product where peopel submit resumes/job postings (this works just fine w/ members logged in). but I need people who are not members to be able to submit job postings. ( so they need to be able to create and edit the entry for it to be pushed to a review status. ) I am trying to do this w/o changing my Objects because I want to be able to come up w/ a idiom of doing this for all CMF objects (since you may want people who are not members to submit Calendar Events, for instance). if im not giving enough information please help. I'm willing to spend time doing this. I am so far down this road and I've committed to someone i would have it done. any help would be appreciated, ~runyaga

ZClass and ZCatalog
by Tim McLaughlin 06 Jul '01

06 Jul '01

Marco, The other option is to use ZClassEvents which will let you write code that runs when properties are changed. Then you can index in 1 or 20 catalogs, and send emails, whatever. CatalogAwareness, then, is no longer necessary (since it is limited to one catalog anyway).

Bug in TransparentFolders ???
by Andre Schubert 05 Jul '01

05 Jul '01

Hi all, i think i have found a bug in using TransparentFolders. Let it explain step by step. First the Structure: Folder_A Folder_B_Transparent You have Folder( Folder_A ) and create a new TransparentFolder Folder_B_Transparent in Folder_A. Then go to the SecurityManagement of the Folder_B_Transparent and Disable the acquire permission setting of any permission(s), maybe Use MailHost Service or so, and save the changes. Then go Back to the Folder_A and try to open the SecurityTab of Folder_A. I got the following error only if any acquire permission setting is disabled in Folder_B_Transparent:  thanks, as

RE: [Zope-dev] ZClass and ZCatalog
by Marco Nova 05 Jul '01

Hello, I solved my problems adding manage_editCataloger with the name of my ZCatalog when I add the object. I've also experimented with the order of the base classes and it doesn't seems to be of any relevancy, so your ZClass can derive from ZObject, JCObject, CatalogAwareBase or ZObject, CatalogAwareBase, JCObject but to make it working, you have to call the manage_editCataloger method in the constructor. regards, - mn > -----Original Message----- > From: Marco Nova [mailto:nova@tera-it.com] > Sent: Thursday, July 05, 2001 2:57 PM > To: zope-dev(a)zope.org > Subject: RE: [Zope-dev] ZClass and ZCatalog > > > > Rename the catalog from 'events' to 'Catalog' and > > CatalogAwareBase should > > start working. > > No, it doesn't work.
