Role Acquisition
by Andrew R. Halko 31 Jul '03

31 Jul '03

Hello all, I have a document that is a few folder layers deep in my site. I want to setup specific permissions for the document in that folder that don't acquire higher level permissions. From what I read, getting the security permissions with python on an object will get local roles, but will go high if they don't exist. I only want to know the local roles. Hope that is clear, thanks for any help! Andrew R. Halko

User Folder
by Robert Jean 31 Jul '03

31 Jul '03

Hello, I am looking for a User Folder that meets the following requirements: - login / logout with cookies - can easily associate additional data with users (e.g. phone#) - stable & well documented It would also be nice if adding SSL support was not too difficult to add. I have looked at mysqlUserFolder, but, being a beginner, I am a bit worried by the documentation that is not very polished. Any suggestion? Robert __________________________________ Do you Yahoo!?

cannot pack ZODB
by duchier＠ps.uni-sb.de 31 Jul '03

31 Jul '03

I am still a newbie and today I tried to pack my ZODB, but that's not working. Turning debugging on doesn't help much: 2003-07-31T15:18:36 ERROR(200) ZODB packing Traceback (innermost last): File /usr/share/zope/zope-2.6.1/lib/python/ZODB/DB.py, line 499, in pack File /usr/share/zope/zope-2.6.1/lib/python/ZODB/FileStorage.py, line 1496, in pack (Object: /var/lib/zope/zope-2_6_1/var/Data.fs) IOError: [Errno 13] Permission denied: '/var/lib/zope/zope-2_6_1/var/Data.fs' How is it possible that I can edit my ZODB just fine (through plone), but I cannot pack it? Apparently, it fails on attempting to open Data.fs for reading (i.e. file=open(name, 'rb')). The file is owned by user zope and group zope-2_6_1, with rw permissions for both. Any ideas? I am stumped! -- Denys Duchier - Équipe Calligramme - LORIA, Nancy, France

SimpleUserFolder Advice
by Michael Geddert 31 Jul '03

31 Jul '03

Hi List, I'm using SUF 0.9.0 on Zope2.6.1. I have to map the methods getProperty/setProperty of SUF's User-Object to ZSQL-Methods because we're using existing table structures from exUserFolders MySQLPropSource. Basically, I need to do a "user.getProperty('email')" (e.g. in a ZPT) to get a string with the current users email adress. This is working great. My Problem occurs when I want to get another Userobject from the Userfolder: uo=context.acl_users.getUser('anton') uo.getProperty('email') .. makes my Zope spin forever, my Browser keeps loading and loading, but nothing ever happens. Here's a snippet of what I added to User.py: def getProperty(self,key): parent=getattr(self,"aq_parent",None) context=getattr(parent,"aq_parent",None) # Check here later for context # Get Property from DB via ZSQL result=context.get_my_prop(myprop=key,myusername=self.name) return result[0][0] get_my_prop is a ZSQL Method and it works fine. I suspect "context" to break away within User.py at some point, maybe because the Object is not "wrapped" in Acquisition which would mean the ZSQL-Methods never get triggered (not sure exactly, somebody enlighten me plz). I also tried to let the Userfolder return User[dict].__of__(self) at some point, but that did not do the job either. Could someone point me to the right direction plz ? This is starting to get me frustrated Cheers, Michael

Creation of components for use across many sites.
by Alec Munro 31 Jul '03

31 Jul '03

Hi List, I've been working using Zope to build a set of components intended to be abstract and reusable. These components currently exist as folders, with each folder having a set of page templates, Python scripts, and SQL queries (and sometimes other stuff). The idea is that for a given site, I will declare that I am utilizing component X, and the component's default scripts and templates will allow for all the functionality I need. However, there are many cases where I need to override a given template or script in a component. I have this working to a degree, by having a folder called "site" in each component's folder, and in that folder I have the replacement scripts/templates/etc. Then I simply change my references like the following: "componentX/HTML/someTemplate" becomes: "componentX/HTML/site/HTML/someTemplate" "componentY/someScript" becomes: "componentY/site/someScript" As I said, this works. The problem is the folder that contains the components has to be copied to each site's root folder. What I would like is a system where in the root of my zope, I can have one folder for the components, and then in each sites folder, I can create the overriding scripts. This is complicated a slight bit by the fact that I need all URLs on a site to be within that site's folder. So I need to be able to call a URL like: "http://www.somesite.com/components/catalogue/buyStuff" and if I have overridden the "buyStuff" script, have it call the overridding script, but if I haven't, I need it to somehow acquire "zopeRoot/components/catalogue/buyStuff". I'm sure I haven't explained this properly, or there's something obvious I'm overlooking, so please ask questions as if I were terminally stupid :) Thanks for your time, Alec Munro

problem trying to run in debug mode
by Tim Lynch 31 Jul '03

31 Jul '03

I'm having a problem trying to run in interactive debug mode. I have stopped my zope process. cd'ed to lib/python ran ../../bin/python import Zope, ZPublisher so far, everything is OK, the import works fine then, I try to view my root-level page: ZPublisher.Zope('/') I get: Status: 200 OK X-Powered-By: Zope (www.zope.org) Python (www.python.org) Content-Length: 0 ____________________________________________________________ that's it, that's all that displays. I'm expecting to see the source for my root-level index_html, but it's not displayed. next, I try to access a page template in the root folder: ZPublisher.Zope('/foobar') I get: Status: 404 Not Found X-Powered-By: Zope (www.zope.org) Python (www.python.org) Bobo-Exception-File: /usr/local/AgPortal/lib/python/ZPublisher/HTTPResponse.py Content-Type: text/html Bobo-Exception-Type: NotFound Bobo-Exception-Value: <TABLE BORDER="0" WIDTH="100%"> <TR VALIGN="TOP"> <TD WIDTH="10%" ALIGN="CENTER">   </TD> <TD WIDTH="90%"> <H2>Site Error</H2> <P>An error was encountered while publishing this resource. </P> <P><STRONG>Resource not found</STRONG></P> So Content-Length: 877 Bobo-Exception-Line: 626 <TABLE BORDER="0" WIDTH="100%"> <TR VALIGN="TOP"> <TD WIDTH="10%" ALIGN="CENTER">   </TD> <TD WIDTH="90%"> <H2>Site Error</H2> <P>An error was encountered while publishing this resource. </P> <P><STRONG>Resource not found</STRONG></P> Sorry, the requested resource does not exist. <p>Check the URL and try again.</p><p><b>Resource:</b> http://127.0.0.1/Zope/foobar</p> <HR NOSHADE> <P>Troubleshooting Suggestions</P> <UL> <LI>The URL may be incorrect.</LI> <LI>The parameters passed to this resource may be incorrect.</LI> <LI>A resource that this resource relies on may be encountering an error.</LI> </UL> <P>For more detailed information about the error, please refer to the HTML source for this page. </P> <P>If the error persists please contact the site maintainer.

Is that standard? If I'm running zope normally, I can display foobar with http://127.0.0.1/foobar I'm running 2.6.1 any help with getting debugging going would be very much appreciated --- Tim Lynch tlynch(a)nal.usda.gov

Interfaces to imported python modules
by Matt 31 Jul '03

31 Jul '03

I seem to be having a problem accessing attributes and methods of objects created inside a custom Zope product from python scripts and ZPTs. I am not sure whether this is a misunderstanding of the security access rules described in the Zope Developer's Guide, or perhaps just the wrong way to think about exposing python objects to python scripts and ZPTs. The basic scenario in my product module is this from SomeWhereElse import ObjectA Class MyProduct( Folder.Folder, Persistent, Implicit ) def __init__( self ): self.dataObjects = [] def createAndAddDataObject( self ): self.dataObjects.append( Data( ) ) def getDataObjects( self ): """ return the dara """ return self.dataObjects Class Data: def __init__( self ): self.data = ObjectA() ---------- So not very interesting, and I have skipped all the usual product and _p_changed bits, I'm simply demonstrating the relationship between product class, a custom data class, and classes from SomeWhereElse. in SomeWhereElse, ObjectA creates and holds references to many other Objects of many different classes. The problem is that I can call a method such as getDataObjects from a python script and get back a list of objects of type Data. However I cannot access the attributes or methods of the ".data" attributes of these Data objects. No amount of setting the following in either the Product class or the Data class helps. __allow_access_to_unprotected_subobjects__=1 security = ClassSecurityInfo() security.setDefaultAccess("allow") The only option I feel I have is to explicitly define in Data or MyProduct getters/callers for all the methods and attributes of the classes defined in SomeWhereElse using proxy classes with the appropriate security settings set. This seems a bit cumbersome. Any pointers would be much appreciated. regards Matt
