I think the key to your problem is the "mapping" option of dtml-with. If
your class/External method returns a dictionary, you can add it to the
namespace like so:
You do not need to explicitly create a new InstanceDict yourself,
dtml-with takes care of that.

What your method is doing, is stepping through every object at the root of your Zope server. Not every object there is accessible by anonymous. Even in a fresh Zope installation, Control_Panel is restricted to managers, so that is the likely culprit. To get around this problem, there is an argument for dtml-in called "skip_unauthorized" which will automatically skip over any objects that the current user is not authorized to access. Changing your dtml-in statement to: Will prevent this error. However, you will get every little object in your root directory. So, standard_html_header, index_html, standard_html_footer, etc. will appear. If you want to exclude these, specify just the meta types you want to objectValues.

RE: [Zope] Version Control in Zope / Managing releases
1) "Code Collisions." - Developers overwriting each other's work. 2) Partial updates - Right now, we have new pages for marketing content that are held up because we don't have our new features for the application done yet. So we can't update marketing pages without updating the app at the same time, (one ZODB) unless we directly update the production servers. (Eeek!) Forgive me if this is overly simplistic, but these problems can both be addressed or at least worked around by using versions, no? Each developer should have his/her own version object. To lock the object (and solve #1), a developer just needs to open it and click change. Then to unlock whatever was worked on and commit it, save the changes to the version. Granted this means only one person can work on an object at one time. This can be worked around by proper modularization of your app. Also, developers need to remember to save their version changes so that others can work on those objects too. This also has a side benefit of letting you document your changes in a more meaningful way. Also, an entire set of changes can be rolled back if it breaks something. #2 is more about what versions were designed for. Just work on the app code in a version and don't commit it until it's ready. Granted this assumes that you have sufficiently separated the data, layout and code and aren't using a lot of external methods. If this isn't a possible solution, I would just create a production version of the feature in one folder that might not be complete but can be updated, and work on a second copy in another folder that isn't accessible to everyone yet. If this won't work please elaborate on your design and maybe someone will have better idea.

RE: [Zope] Strange behaviour on authorization
The fact that your external method returns a class instance explains why it
fails where it does instead of in the dtml-let statement. It looks as though
Zope is allowing the object to be returned, but balking when you try to
access it. I think I will need to see exactly what your external method and
the returned object are doing before I can try explaining this behavior.

Aha, it worked in 2.1.6 eh? That's the tip off. A *major* change between
2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the
security level of the _owner_ of the method, regardless of whether this is a
lower or higher level than the currently authenticated user. My guess is
that your method has no owner (which is what pre-2.2.x objects default to
when run under 2.2.x). This means it is running as anonymous which does not
have rights to do what you want. Specify an owner for the method that has
sufficient rights to do what you want and try it again.

Which seems a little bit broken to me, since unless I missed something you have to choose not to add a vocabulary when you first create the ZCatalog, and then go add one with substring checked from the management screens afterwards. In the code the difference between the checkbox checked and not checked is two different lexicon implementations, not just the setting of a flag. So you can't just change the flag, you have to see to it that the whole lexicon gets rebuilt. I haven't checked into how you do that yet . As for your question about different vocabularies, punctuation, and globbing support, all of that happens at the lexicon level. That is, the lexicon implements the breaking up of strings into indexable words (calling the splitter) and it also implements the expansion of wildcards into matches. It gets to do that *before* the text index machinery parses the query, so it can decide on the syntax rules, as far as I can see. So if you want a Vocabulary that supports punctuation and globbing, you'll have to write one, and then *you* get to decide what the syntax is to handle the case you ask about . --RDM ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

This appears to be a classic aquisition gotcha. You can use the "only" option of the dtml-with tag to eliminate namespace conflicts.

RE: [Zope] substring search on zcatalog textindex
TextIndexes index individual words separately (using a vocabulary object to
identify each word in the catalog). All non-alphanumeric characters (such as
punctuation) are dropped so that excludes searching for "?" or "*" or any
other non-alphanumerics using TextIndexes.
Not much of this is formally documented, but you can review the source (in
Python and C) for the indexing mechanism in:

I created a ZClass subclassing CatalogAware and File. I added a property called text which is text indexed in a catalog. When a Word document is added, a method I created uses the wvHtml utility to convert the Word document to text and store it in the text property. It has kind of a kludgey implementation at the moment, mostly because I want to create a Python wrapper around the wv library, but it's documentation is sketchy and I have other priorities at the moment.

[Zope] ZODB or not ZODB?
I am implementing a document Library using Zope. It has an exhaustive index with several thousand topics in an outline residing on a PostgreSQL database. This works well and I like it. My question is where is the best place to store the documents themselves? They will be static HTML documents ranging from 1-50Kb in size roughly. There will probably be at least 10,000-15,000 of these documents in the library once all is said and done. In my mind I have three options: 1. Store them on the filesystem. 2. Store them in a PgSQL table as blobs. 3. Store them as DTML Docs in the ZODB. I would like to eventually have full text searching capabilities, so that makes #1 less attractive (I would likely need my own Python method to do it). #2 is somewhat of a pain to implement due to limitations in the PgSQL row size and text searching would be slow. With #3 I could in theory use a ZCatalog to implement the searching, so that is done for me. Is ZODB up to the task of storing this quantity of objects? What problems might I run into? Is it a wise idea, could a data.fs file of this size (~3-400MB) become too easily corrupted? Should I use a separate data.fs file just to store the documents (ie using mountedFileStorage)? Or is it better to use method #1 or #2? Information from anyone with experience in this regard is greatly appreciated. -Casey Duncan [EMAIL PROTECTED] ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
