[Skinscript] unable to update property
by Dirksen 14 Jan '01

14 Jan '01

Hi Steve, I ran into a very tricky problem when developing a site with emarket. Here is the structure of my site: root |--acl_users(Membership product) |--emarket |--shoppers The acl_users is an instance of Membership product, which is as a specialist as shoppers, and they both have a WebIC_MemberClass zclass as their rack object class. The difference is that, acl_users stores WebIC_MemberClass persistently, while shoppers just reflects that storage. Here is the skinscript for shopper's rack: WITH acl_users.getItem(self.id) COMPUTE oo=RESULT WITH self.oo COMPUTE email, transCount WHEN OBJECT CHANGED STORE transCount USING self.oo.propertysheets.webic.manage_changeProperties(transCount=self.transCount) When emarket trying to increment a shopper's transCount, I ran into a "ZODB.POSException.ConflictError". The following is the traceback: Traceback (innermost last): File C:\WebSite\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\WebSite\lib\python\ZPublisher\Publish.py, line 199, in publish File C:\WebSite\lib\python\ZPublisher\Publish.py, line 199, in publish File C:\WebSite\lib\python\ZPublisher\Publish.py, line 199, in publish File C:\WebSite\lib\python\ZPublisher\Publish.py, line 195, in publish File C:\WebSite\lib\python\Zope\__init__.py, line 188, in zpublisher_exception_hook (Object: ProviderContainer) File C:\WebSite\lib\python\ZPublisher\Publish.py, line 175, in publish File C:\WebSite\lib\python\Zope\__init__.py, line 235, in commit File C:\WebSite\lib\python\ZODB\Transaction.py, line 251, in commit File C:\WebSite\lib\python\ZODB\Connection.py, line 351, in commit (Info: (('*hdVMVCvgk/wIgJaYf/nkEA==', 'WebIC_MemberClass'), '\000\000\000\000\000\000d\357', '')) File C:\WebSite\lib\python\ZODB\FileStorage.py, line 664, in store (Object: C:\WebSite/var/Data.fs) ConflictError: ('\0039\323C4=\266\210', '\0039\323B\375\036\270U') Is it something wrong with my skinscript? cheers Dirksen __________________________________________________ Do You Yahoo!?

"PrincipiaSearchSource()" dtml-method and Catalog
by Max M 14 Jan '01

14 Jan '01

I have made a dtml method called "PrincipiaSearchSource" in a bunch of zClasses so that my Catalog will index severeal parameters in the zClass, but nothing happens. As far as I can see PrincipiaSearchSource is a default value that is indexed in catalog. Have I misunderstood that? The title gets indexed ok when i update my classes but not the content delivered via the PrincipiaSearchSource method. Does anybody have an idea? I have tried to return via PrincipiaSearchSource in 2 different ways (None of which works): #1 --------------- <dtml-return "var1 + var2 +var3"> #2 --------------- <dtml-var var1> <dtml-var var2> <dtml-var var2> regards Max M Max M.

reindex when a zclass is edited
by Tim Hicks 14 Jan '01

14 Jan '01

I know this has been asked numerous times before (once by me!), and I'm sorry to cover the same ground again, but I've spent all afternoon searching through the list archives to no avail. I have a zclass that is catalogaware (selected first and all that). When I add an instance, it gets cataloged and all is fine. I followed the how to (http://www.zope.org/Members/AlexR/CatalogAware) and successfully made my instance get reindexed when the properties are changed, but I can't for the life of me figure out or find anywhere that can tell me how to make the instance get reindexed when it is edited. I'm assuming that it is similar to the process for reindexing when the properties are changed, but I'm just not sure of the details. If it's not too much trouble, could someone give me detailed instructions (or a link) on how to do this. I'd really appreciate it. cheers tim

DCOracle bug?
by Shai Berger 14 Jan '01

14 Jan '01

Hi guys, As I have written before, we are using DCOracle 1.3.2 / Oracle 8.0.5 on a Linux/i386. We need some LONG RAW columns, and we hold them in a special table long_data, with two columns, long_id (int) and long_data (long raw). Other tables where long data is needed hold references to this table. We have recently encountered a peculiar behavior: In Zope, if we issue a query which selects many rows with one long column each (essentially, select * from long_data ), it works; if the query selects more than one column, but only one row (essentially, select a.*,b.* from long_data a, long_data b where a.long_id=17 and b.long_id=34 ), it also works; but if we select multiple rows with multiple long columns (as in select a.*,b.* from long_data a, long_data b ) we get an Oracle error indicating a buffer is not allocated to receive the data. Has anyone seen anything like this before? Thanks, Shai.

importing string module in python METHOD - a problem that shouldn't be a problem problem
by Lee 14 Jan '01

14 Jan '01

Hi, I have a Python method that needs to use the string module. In the method body I have the 'import string' statement but when I try it => Error Type: ImportError Error Value: __import__ not found The documentation collaborates that import statements (the string module specifically) can be used in Python methods. The method body is... import string text = details y = string.split(text,"x") studentMatric = y[0] studentRecord = y[1] return studentMatric + studentRecord .., which results in the above error. Can anyone suggest a reason for this? I think (hope) it'll work if I put it in my extensions directory.

REQUEST object - obtaining variables from
by Lee 14 Jan '01

14 Jan '01

Hi, I am having some problems with the REQUEST namespace/object. I understand that if I submit form data then it can be retrieved using the REQUEST object. I have looked at Chapter 7 (Advanced DTML) for support but I'm still no closer to success. I have a DTML method, which passes an unknown number of arguments with unknown names to another method. For example, <form action="display"> Name <input type="text" name="name1"><br> Age <input type="text" name="age1"><br> Name <input type="text" name="name2"><br> Age <input type="text" name="age2"><br> <input type="submit"> </form> I would like the display method to simply show each of the variable's names and values i.e. iterate through each variable in the REQUEST object. Maybe I've overlooked something in the Zope documentation but could someone supply a useful snippet of code to get me started?

RE: [Zope] hasRole bug or feature in 2.2.?
by Randall F. Kern 13 Jan '01

13 Jan '01

> From: Ron Bickers [mailto:rbickers@logicetc.com] > If this is true, it explains clearly Zope's behavior. It's really a browser > "feature" and not a Zope issue at all. Yes, that's the problem. My solution is to use a custom UserFolder, which sets a temporary cookie when a normal HTTP login is accepted. This cookie is then used for further validation. The class I use is rather complex, providing persistent login in addition to these features, and randomly re-creating the cookie so one can't easily spoof a user, but this simple class will get you going: class UserFolder(AccessControl.User.BasicUserFolder): def validate(self, request, auth='', roles=None): user = AccessControl.User.BasicUserFolder.validate(self, request, auth, roles) if user is AccessControl.User.nobody or user is None: if request.cookies.has_key('login'): user = self.getUser(request.cookies['login']) else: request.response.setCookie('login', user.getUserName(), path='/') return user -Randy

TREE tag - not showing Folderish objects that contain no sub-objects
by Kevin Howe 13 Jan '01

13 Jan '01

I currently have a TREE tag as follows: <dtml-tree expr="PARENTS[-1]" branches_expr="objectValues()" sort=id> which basically says: "Display objects which can contain sub-objects" such as Folders, Folderish Products, ZClassed based on ObjectManager, etc. What I would like to do is display these objects, but ONLY IF they currently contain some objects, so that if an object does not contain any subobjects at the moment, it is not displayed. Something like the following: <dtml-tree expr="PARENTS[-1]" branches_expr="_.len( objectValues() ) > 0" sort=id> Unfortuntately the above doesn't seem to work (can Python's len() function be called from DTML?). Does anyone know what expression might do what I am looking for? Kevin
