It is strange that it worked before you added the manager proxy role: "manage_addProperties" is for good reasons protected. It is strange, too, that the proxy role does not work in the other installation. Do you use Zope 2.2? In this case, maybe, something is wrong with the owner of the method. Moreover, proxy roles are no longer inherited to called methods. Dieter

It has nothing to do with Chapter 10. Dieter

Re: [Zope] ZopeBook ZCatalog Question

ZCatalog uses the method "objectItems" to find the children of an object in the ZCatalog method "Find Objects to Catalog". Thus, to extend cataloguing into a database, you will need an object the "objectItems" of which will return the database records you want to be cataloged. You can not use raw database records, as the catalog requires each catalogued object to be URL addressable (it uses the URL to identify the object). Thus, you must use a pluggable brain (--> Advanced tab of Z SQL methods management interface) to provide the "absolute_url" method (or whatever ZCatalog will tell you, it does not find during the cataloguing). As you probably will be interested, that the object can be retrieved with the URL, you will also need to learn about "direct traversal". This is make database records URL addressable. As you may see, it is not trivial. Dieter

I like to repeat my general remark (you find it several time in the (searchable) list archiv ;-)): Whenever, you can do something with the Zope management interface, you can do it programmatically. Moreover, a look at the source of the Zope management pages (mostly DTML and mostly in the OFS/ and App/ subfolders of your distribution), will tell you how to do it. Dieter

Re: [Zope] Passing lists in a get request (ZCatalog Search)

You add also the search criteria to your URL? I.e. you use your_method?sort_on=theme&theme=xxx&theme=yyy If you simply append "?sort_on=theme" to your_method?theme=xxx&theme=xxx Then, you would have two '?parameter' sections. Only the last would be taken. The first would be part of the path which should give you a NotFound Exception. But maybe, there is a bug somewhere. You could also use a <dtml-call "REQUEST.set('sort_on','theme')"> in "your_method" before the "dtml-in", in case the sort order is fixed. > for example, one of my search criteria is "theme" - there are four possible (Air, Land, Water, and Waste). > > the request would look like: > search?meta_type=Publication&theme=Air&theme=Land&theme=Water > > I can't figure out how to pass a list in the get request. That is a good approach. If the same parameter is repeated, Zope will bind a list of all values to the parameter name. If you would like to be sure to get a list (or no value at all), you can use "theme:list". This will ensure, that a list is bound even if there is only a single "theme" parameter. This is irrelevant for your application, however. > .... difficult to build long list "param=v1&param=v2&...." .... Usually, the browser builds such URL for you (out of a form). E.g., if you use a multiple select box or several check boxes with the same name, the browser will construct corresponding "param=v" for each selected/checked value. > .... length limitation with get .... HTTP 1.1 (and I think HTTP 1.0) has removed the length restriction. At least Zope/Zserver will not impose an unreasonalble limit. Someone else suggested to use a post (rather than get) request. In general, I would warn you against this solution. It will break the "dtml-in" batch support. Dieter

Thies =?ISO-8859-1?Q?B=E4hr?= writes: > .... authorization problems for TTW products > after 2.1 --> 2.2 transition .... The reason is simple that you do not find upgrade documentation for TTW products: there should be nothing to worry about. Thus, you have a case, that should not be. Let the authorization fail and post the resulting traceback. Maybe, we see something. You may also look into the (searchable) list archive. There have been several threads about similar problems. And, I (at your place) would use Zope 2.2.4 rather than 2.2.2. Maybe, the problem disappears (because a bug was fixed). Dieter

Re: [Zope] Making lots of external data searchable?

Anselm Lingnau writes: > .... indexing big mail archives from Zope .... You can use the Zope product "LocalFS" (maybe also "ExternalFile") to wrap external files into Zope objects (without storing then in the ZODB). Newer versions of "LocalFS" allow you the catalog its contents with ZCatalog. However, before you commit to ZCatalog, make some performance measures. ZCatalog tends to require large amounts of time and memory to build its indexes. Dieter

Re: [Zope] Intercepting NotFoundError with standard_error_message

Philipp Auersperg writes: > .... missing control over stack trace .... I agree with you: you should have control over this stack trace. However, I fear, you will need to change the Zope source to get this. It should be easy to implement: Bind the traceback to a variable in the namespace, the "standard_html_error" page is rendered in rather than appending it directly. The "standard_html_error" is free to do with it whatever it likes. Maybe, you file a feature request into the Collector. Dieter
