ZPatterns Rack question..
by cs＠comlounge.net 28 Apr '01

Hi! First of all one note to the sql attribute provider: My problem seems to be solved now. Actually it was quite easy.. dunno why it took the long way.. thanks anyway to Phillip and Steve! But I have another problem now: I have some rack with persistent objects in it. Now I want to migrate my site to production. Problem: If I do this more often and the objects are within some Rack, then also these get copied to the production site and the old objects will get deleted there. Is there any way to first backup the contents of some rack? Or do I need to construct it all as external storage? (basically most things are in an sql db already, I just put image data etc. into the rack directly as I don't need relational access to it..) Actually I know how to read the objects from the BTree but I dunno how to store them again into another rack (which has the same storage attribs of course). Can I simply use _setRack()? I guess not, eh? :) Thanks for any hints in advance! regards, Christian -- COM.lounge http://comlounge.net/ communication & design info(a)comlounge.net

ZCatalog features
by Morten W. Petersen 28 Apr '01

28 Apr '01

Hia guys, A couple of comments and questions about the ZCatalog: Is it possible to pass an argument to the catalog so that returned brains would instead be actual objects? Given that we have to manually join search results, because ZCatalog doesn't support ORs etc (for FieldIndexes), wouldn't it be useful to have some sort of tool that could take a set of results, and return a result with only unique values? Cheers, Morten

Re: [Zope-dev] Trying to set roles/permissions programmatically - Now I have a headache!

My standard response to questions like this: You know, you can do this via the Management Interface. Its code will tell you, how you can do it: the necessary method names and their parameters. After you know the names, you look for further documentation: the Zope Help, maybe the new Zope Developer Guide, the source. The source for the updating of permissions is "AccessControl/dtml/access.dtml". The methods are defined in various Python files in "AccessControl". Dieter

Permissions to change Acquire Permissions?
by Tim R Ansell 28 Apr '01

28 Apr '01

I was wondering if it would be possible for a new permission to be created, this permission would let (or stop) people from changing the Acquire Permissions check boxes found in the Security Tab. The reason I would like a permissions like this is that some users that need to give people permissions are exactly trusted. This means that they could change the acquire permissions and circumvent people with "Manager" or higher privileges. This type of permission could be very useful for zope to have but would most properly require changing of how permission changing is handled? Mithro

ZStyleSheets

Yo, when trying to use the ZStyleSheets, we only found a zip, but no tarball. After unzipping, it didn't work because appearantly the zip was made for some OS that has a case-insensitive file-system. after renaming the files (zstylesheet* -> ZStyleSheets* aso) everything behaved as expected. It's a cool product though. you guys be warned. have fun, Sloot

Clicking on manage_debug kills Zope, honest. Anyone else seen this? Nothing printed to stderr or anything useful. Sigh. B 29501752 2001-04-27T17:50:02 GET /Control_Panel/DebugInfo/manage_main I 29501752 2001-04-27T17:50:02 0 Windows 2K, Zope 2.3.0. Cheers. -- Andy McKay.

Surely a blank query mapping > should return nothing, not everything? > (at the least it'd be nice if this was configurable ;-) No! Please not! It is very natural that an empty query returns everything when subqueries are combined with "AND". Any time, you add a subquery, the result set is a subset of the former one. For this to work out without boundary exceptions (we all hate them, I hope!), the empty query must be the complete set. Of course, if subqueries are combined with "OR", the empty query should return no hits.... > > + Depending on the type of index you are querying, you may be > > + able to provide more advanced search parameters that can > > + specify range searches or wildcards.

The section above says, your question would be answered there. Dieter

They help memory very much. Your question has been answered some days ago... "getSecurityUser" documented in "AccessControl.DTML" Dieter
