How to logout users when using LoginManager?
by Brad Clements 30 Aug '00

30 Aug '00

I've searched the zope website for tips on how to truly logout users, but I can't find any information. I'm using LoginManager, with GenericUserFolder. I see mention of cookie auth methods, but I have no idea how to use this. So, I'm using basic auth (I assume). Can anyone share some tips on how to logout users from a web page, using cookies or otherwise, allowing them to relogin as another user without having to quit/start their browser? Thanks..

symbolic links or invisible objects..?
by Geoffrey L. Wright 30 Aug '00

30 Aug '00

Zopistas: Am working on a simple content management system for about 6 sites, and so far, so good. It's my first medium-sized Zope project and Zope has been wonderful to work with so far. However, I've been tasked with the project of creating the simplest possible interface for some very non-technical content managers. So the first thing I did was abstract out the content from some fairly complex formatting. This was easy, and now I have a site where all the content that theae people need to touch always lives in an object called page_content. Objeects by this name now exist at many points in the site. Aparently the fact that a number of other non-content objects are visible at the same level of heirarchy in the site is a problem. So my question is this: Is there any way to make zope understand something like a UNIX symbolic link? If so, I could easily create a single directory with a symlinks to all the appropriate objects in the site. Content managers would then have access only to this dir and would therefor see all appropriate objects. Or perhaps there is a way to make other objects invisable to those w/out the necessary permission to use them? I've played with Zope permissions a but, and haven't yet found a way to do this. Or is the some other way entirely to look at this problem? TIA for any help on this. //glw

ZCatalog in 2.2.x
by Terry Kerr 30 Aug '00

30 Aug '00

Hi, I have a python product which uses a ZCatalog and CatalogAware products. The catalog has a number of Field and TextIndex indexes. Search the ZCatalog has worked fine when my product is instantiated in 2.1.6. But now when I instantiate my product in 2.2.0 or 2.2.1, searching only works when I search using a field index. Searching using a textindex always results in an empty result, even tho I can see the words I am searching for in the Vocabulary! Any suggestions? I have tried reindexing, completey recreating the Zcatalog, recreating the Vobulary and reindexing, and nothing has changed the behaviour. Are textindexes simply broken? ZCatalog seems very volatile to me! Every time I have upgraded way back from zope2.1.3, something in zcatalog has changed and boken my product. So far I have managed to find fixes, but this one has got me baffled!! -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions Pty Ltd (www.adroit.net) Phone: +613 9563 4461 Fax: +613 9563 3856 Mobile: +61 414 938 124 ICQ: 79303381

This means, you want to look at the source of "manage_delObjects" (-> "OFS.ObjectManager") to see, how it sends you to the management interface. You will see, that it contains: if REQUEST is not None: return self.manage_main(self,REQUEST,update_menu) Thus, do not pass it a REQUEST. This implies, that you do not call it directly from the form, but call a dtml method from the form, that then calls "manage_delObjects" with the "ids" and no REQUEST. It may be necessary to set a proxy role for this method. > - I don't necessarily want to give the 'ContentManager' rights > to delete objects; I'd rather manage this through a delete > method with the appropriate proxy role. Then, this should get your method mentioned above. Dieter

RE: [Zope] how to keep stuff out of undo
by Chris McDonough 30 Aug '00

30 Aug '00

Oo. That's bad. There is no way to selectively make something persistent but non-historying using FileStorage. I would suggest possibly using dbmStorage (or its brother BerkeleyStorage) to store this big data structure, as it does not perform undo. You might be successful using these storages in conjunction with the "mountable storage" option, whereby you can "mount" additional storages into your folder structure. Perhaps use FileStorage for "normal" operations but place the product's instances into the "mounted" section of your site (backed by dbmStorage or BerkeleyStorage, where it won't be historied). I've never used mounted storages, so I can't explain how it's done, but I'm sure other folks here can. Mounted storages fall down with versions (do not use versions in conjunction with mounted storages, it will do bad things to you). > -----Original Message----- > From: Roman Milner [mailto:roman@speeder.org] > Sent: Tuesday, August 29, 2000 11:29 PM > To: zope(a)zope.org > Subject: [Zope] how to keep stuff out of undo > > > Hi.

GUF and manage_addGenericUserFolder not working
by Jason Byron 30 Aug '00

30 Aug '00

I try to call the function manage_addGenericUserFolder in a DTML Method but I keep getting a NameError for it. It's as if Zope can't find the definition. I'm stumped as to why it won't work in DTML. - The product is installed and not broken. - I can add GUF's under the management screen with 'Add' and everything works fine. - I've tried to make the call with all of the possible parameters but nothing helps. - manage_addUserFolder works fine. Has anyone else had this problem? I just upgraded to Zope 2.2.1 and I haven't tried an older release. Do you think this might have to do with the changes to the security model in 2.2.1? Should I use manage_clone instead? Thanks for any help, Jason __________________________________________________ Do You Yahoo!? Yahoo!

Z Database Connections - pass uid/pwd to RDB
by Philipp Auersperg 30 Aug '00

30 Aug '00

When you create a Z database connection you must supply a fixed connection string with a fixed uid/pwd to open that connection. So every user that connects to Zope connects with the fixed uid/pwd to the relational database. Is there any way or workaround to dynamically pass the Zope uid/password to the relational database? This is important when user security is maintained by the database scheme. Not that I really want this feature for my use but we have projects where the customer has the database model ready and wants the users to be individually authenticated at the relational database (in this case: Oracle). thanks Philipp Auersperg(zwork)

Logfile analyzer
by Ian Bicking 30 Aug '00

30 Aug '00

I've been making some log analysis code on my site, and have realized that a lot of other analyzers aren't that great -- or, at least, that it's nice to have the control that editting the actual code can give. (for instance, I ignore all requests that come from my ISP, since I don't need to know what my surfing habits are; I ignore all pages that end in "manage.*"; etc.) Anyway, I've been thinking of polishing and expanding what I've written some, so it's suitable for public use (or at least use by people who know Zope/Python fairly well). But this requires work that I probably wouldn't do for myself -- so I'm writing to see if there are enough people who have interest in this to make it worth it. [Or if this already exists and I just haven't found it] Cheers, Ian
