Help with UserDB
by Jason Jones 05 Aug '99

05 Aug '99

I just changed my user database schema to match that of the UserDB product, and installed UserDB with cookie-based authentication. Immediately after doing that everything became inaccessible. Now, I get the response: Unauthorized You are not authorized to access this resource. Username and password are not correct. Traceback (innermost last): File /web/zope2/lib/python/ZPublisher/Publish.py, line 256, in publish_module File /web/zope2/lib/python/ZPublisher/Publish.py, line 145, in publish File /web/zope2/lib/python/ZPublisher/BaseRequest.py, line 430, in traverse File /web/zope2/lib/python/ZPublisher/HTTPResponse.py, line 538, in unauthorized Unauthorized: (see above) For every page, even public ones. I set up the UserDB folder at the top level of the object heirarchy, is this the problem? Note, the superuser login no longer works and basically I can't access Zope at all. Any suggestions would be greatly appreciated (especially how I could get back into Zope). Thanks, Jason Jones jason_j(a)countermedia.org

Acquisition change between Zope 1 and 2?
by Andrew M. Kuchling 05 Aug '99

05 Aug '99

Today I moved some code from Zope 1 to 2, and ran into an incompatibility. I have a folder named 'process' with various bits of DTML in it. One DTML document called matching_html contains . add_operation_link is a DTML method; in the process folder, it's empty. In a subfolder of 'process', I create a different add_operation_link DTML method which contains some actual content. The intention is to have a hook; subfolders of 'process' can override it to insert a bit of their own content, avoiding the need to modify more complex DTML methods. In Zope 1, this works as I expect; subfolders define add_operation_link, they acquire matching_html from the parent folder, and it calls the locally-defined add_operation_link. In Zope 2b1, this breaks because the matching_html in the parent folder calls the version of add_operation_link in the same folder; the overridden version of add_operation_link is never called. If I copy matching_html into the subfolders, it now calls the overridden add_operation_link, but now I have duplicate code to maintain and debug. Is this a bug in 2.0b1 or a deliberate change? If the latter, what are the semantics that changed, and how do I write hooks like this? And won't this break a lot of code? -- A.M.

You can't use the '+' operator to concatenate different types (a string and an int, in your case).

Also, your redirect is wrong, since redirect() takes an URL, not the string name of a variable to read.

hey everyone, i am having BIG problems using REQUEST.set within Zope. I am trying to dynamically build a URL to redirect the browser to using the following code:   but this is throwing back an error on the REQUEST.set part, the error looks as follows: Object: REQUEST.set('jumpToBase', '../foodirectory/index.html?memberNum =' + userDetails)) File <string>, line 0, in ? TypeError: (see above) The userDetails variable is a INT value pulled from a database and i cannot understand why it is falling over on this!! Does anyone have any thoughts? Cheers, Wom..

ZSQL methods for the moment have a user interface for inserting a brain, but Catalog can also work with pluggable brains (albiet only programaticly, there is no UI at the moment for PBs in Catalog). You could create a ZClass that subclassed catalog and provided it's own kind of brain. After ZClasses bake a bit more, I would like to add add an interface to Catalog (and extend ZSQL's interface) to allow the admin to specify either a python class on the filesystem, or a ZClass. This way you could develop your brains through the web and then plug them in. -Michel > Thanks, > > = Joe = >

SQL METHODS - Obtaining ROW IDS in an <IN> STATEMENT
by Theodore Patrick 05 Aug '99

05 Aug '99

Here is the situation: I have a method called item_method. It contains SQL:SELECT that returns 10 rows of data. When I want to print this to a page in ZOPE. I use an <IN> Statement as follows. Currently the data set from the database does not return a row number, so I need Zope to make one up as it prints the HTML. The data set has two columns called this and that. I need the code that generates the  in the following code.  ROW_NUM=  THIS=, THAT=  As always - Thanks in Advance. Theodore E. Patrick http://www.ishophere.com Where do you shop?
