Catalog Query Feature Request, was: RE: [Zope-dev] An idea for Un iqueValuesFor

I could definitely see the value of a unique-values query into ZCatalog, especially for creating things using <dtml-tree> using keywords, etc... On a slightly related (well, not really) note, CatalogQuery looks like it would solve a lot of problems I have had with a very Catalog-intensive application. One thought I had - I might suggest the possibility of adding a fuzzy matching operator to CatalogQuery that performs the function of wrapping wildcard searches on search terms for Text Indexes, supposing the Catalog is using a globbing vocabulary: ~= as an operator would mean an approximate (substring) match So a search for 'title ~= "engineer"' would perform a search for '*engineer*' and return results containing words like engineer, engineers, engineering, etc. Right now, I attempt to safely rewrite REQUEST['someFieldThatIamSearching'] with a Python class method that uses a zillion re.sub() calls to wrap search terms in * characters; I wonder if there is a way to alternately implement something like this at a lower level, perhaps in CatalogQuery; I get the feeling it would be quicker and much more simple. If something like that were implemented as well as some equivalent to sort_on, I'd stop pulling my hair out with traditional workarounds and definitely switch all my stuff to use CatalogQuery instead... Thoughts?

An idea for UniqueValuesFor
by Chris Withers 04 Aug '01

04 Aug '01

I quite often need to do something like: results = MyCatalog(meta_type='Person',continent='Africa').uniqueValuesFor('FirstName') ...which would give you the minimal list of firstnames of people who live in Africa. A bit contrived but I seem to bump into lots of real world cases where I need to do similar. What I currently have to do is the brutal and slow approach of "walk through the results" :-S But Anthony came up with a great suggestion: > What would make more sense (maybe?) is > results = > MyCatalog(meta_type='Person',continent='Africa',uniqueValuesFor='FirstName') What do other people think? Is there a nice fast way of implementing this? cheers, Chris

can you import a Product into a python script ?
by Simon Michael 03 Aug '01

03 Aug '01

Python scripts are super-cool.. except I can never do what I want. Safety, shmafety. Am I right in thinking the following can't work ? ## Script (Python) "zwiki_tests" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## # run ZWiki test suite via simple through-the-web test runner from Products import ZWiki return ZWiki.tests.run()

Re: [Zope-dev] Help on Zope security needed ...

Just resending to zope-dev, silly me adressed zope at first... Hi, just to give a little more weight to that... > > The funny thing is: http://.../ROOT/FOLDER/title will work fine ... > Indeed, funny. Should probably not happen. Are you > sure, you get the "title" form root and not that from "FOLDER" > (it has a "title" of its own). Just tested it with blank zope 2.3.3 / method - testfolder - userfolder with user test and manager role (just in testfolder!) The following doesn't work for user test: http://localhost/method/manage The following _will_ work for user test: http://localhost/testfolder/method/manage and let's me change method, which is contained in zopes root. Hmm, this shouldn't be so, should it? cheers, olier

Security still wierd
by Michael R. Bernstein 03 Aug '01

03 Aug '01

I have a Python Product that I have mostly finished, and now I want to add security to it. I am importing Globals.InitializeCLass and AccessControl.ClassSecurityInfo. I am adding a ClassSecurityInfo instance in my class, and I am calling InitializeClass on my class at the bottom of the Module. I have run into the following problem: Classes in Python products that inherit from OFS.SimpleItem.SimpleItem or OFS.SimpleItem.Item have an attribute set: __allow_access_to_unprotected_subobjects__ = 1 This allows all class attributes and subobjects that are not explicitly private or protected by a permission to be accessed from the restricted code environment, or directly traversed into by a web browser. Supposedly, setting __allow_access_to_unprotected_subobjects__ = 0 inside your class will return the behaviour to the default (access not explicitly allowed is denied), but this doesn't seem to work for me. Adding explicit permissions to methods *does* work, but only for methods. Attributes such as dictionaries would be left unprotected. Can anyone suggest what I might be doing wrong? I am working with Zope 2.4 Thanks, Michael Bernstein.

Help on Zope security needed ...
by Joachim Werner 03 Aug '01

03 Aug '01

Hi! I am trying to get into understanding the Zope security machinery (Zope 2.4), and it seems to not quite do things as expected: I have a Folder hierarchy like this: ROOT --FOLDER - In ROOT I have a method "title" and the "index_html" method - I have a user "Charly" that has ther role "TitleViewer" in a user folder in FOLDER - the method "title" has View permissions linked to "TitleViewer" and "Manager" - the "index_html" method contains a string "<dtml-var title missing>" Now I go to http://.../ROOT/FOLDER/index_html. My user is "Charly". I would expect to see the title now, but I don't. If I remove the "missing" from the <dtml-var title>, I will get a key error for "title". The funny thing is: http://.../ROOT/FOLDER/title will work fine ... Also, if the user is in the ROOT folder, everything works fine. But then I can't really do what I want, i.e. restrict permissions to the FOLDER folder ... What is wrong there? I don't have a clue what Zope protects why and how. I always thought I knew about Zope security. But as soon as I add local roles or local user folders, things become very strange. I mean, if the idea is that the user must have the "TitleViewer" role in ROOT to see title, then http://.../ROOT/FOLDER/title should not work (but it does). But if the idea is that objects are acquired first and then user roles are checked against them, http://.../ROOT/FOLDER/index_html should display the title stuff (but it does not). Cheers Joachim

ZODB Mounted storage - links gone
by Brad Clements 03 Aug '01

03 Aug '01

I'd like to mount (graft) multiple ZODBs into Zope so I can store some folder data in it's own .fs file. Searching Zope for "mounted storage" returns http://www.zope.org/Members/jim/ZODB/MountedDatabases Which doesn't exist, even on classic.. Any ideas where to go, or is this term no longer used?

fixupZClassDependencies broken in 2.4.0?
by Chris Withers 03 Aug '01

03 Aug '01

Hi, I uninstalled some ZClass-based products while migrating a Zope instance from 2.3.2 to 2.4.0, however, I get the following disturbing log entries: ------ 2001-08-03T13:22:59 INFO(0) Zope A broken ZClass dependency was found in the global class registry. This is probably due to a product being uninstalled. The registry has successfully been rebuilt. ------ 2001-08-03T13:22:59 ERROR(200) Zope A problem was found in the global product registry but the attempt to rebuild the registry failed.

Why is it happening? what should I do? cheers, Chris

RE: [Zope-dev] Problems with zclass and instances!!!
by Tim McLaughlin 03 Aug '01

03 Aug '01

Edgardo, Have you tried accessing the __dict__ attribute of the instance in an External Method. This should let you know if the attribute in question is being inherited or not. Try something like this... def isOnInstance(self, name): if self.aq_base.__dict__.has_key(name): return "I've got it" else: return "My parent has it" Note: if you ever call manage_editProperties, all properties on that sheet will be set on the instance and not inherited. Use manage_changeProperties to only set a those specified...

SOAP support: request for comments
by ppetru＠ppetru.net 03 Aug '01

03 Aug '01

Hi, Almost a year ago I did a quick hack which added SOAP support to Zope. It really was something I played with in order to understand what this whole SOAP thingie is about. To my surprise, though, my web server access logs show that people have actually downloaded it :) Now, one year later, the situation is different (a couple Python SOAP libraries, as opposed to only one) so I'm looking into actually finishing (or redoing) the SOAP support for Zope. For this, I would very much apreciate comments -- especially from those guys who already used my patch, or think they are going to use Zope and SOAP in the future. Thanks, Petru
