[Zope] SiteAccess affects the Zope management interface
I hadn't realized it before, but SiteAccess can cause really confusing things in the Zope management interface! When I installed Zope 2.3.0 and ran it on an unused port number to check it out while the main Zope was still running, the top-level Zope folder displayed with the new look (which is very well done, BTW), but when I would drill down into a folder governed by a SiteRoot object the folders appeared with the old (2.2.x) look. This was quite a mystery until I realized that although the tree frame on the left (and the new top frame) were displaying pages served by the new Zope 2.3.0 process, the right/folder frame was actually displaying a page served by my older production Zope process running Zope 2.2.5! My Zope tree is something like this: / + /subsite1 + /subsite2 subsite1 has a SiteRoot that gives the folder a new Base of "http://subsite1.org". Apache is sitting on port 80 and using ProxyPass to map http://subsite1.org to http://myhost.org:8080/subsite1. Assume the new Zope ZServer is running on port 9090. So the listing for 'subsite1' in the tree display has an HREF of http://myhost.org:9090/subsite1/manage_main. When I click on that, the browser requests that URL from Zope on myhost.org:9090. Because of the SiteRoot object, the server sends back an HTTP 302 response redirecting the browser to http://subsite1.org/manage_main, which the browser dutifully requests. The Apache server gets that request and forwards it via ProxyPass to http://myhost.org:8080/subsite1/manage_main. The other/older Zope server on port 8080 fields that request (with SiteAccess converting URLs) and sends it back to the browser, which displays it in the large/right frame. So now the left frame is displaying the objects served by ZServer on port 8080 but the right frame is displaying the contents of some object served by ZServer on port 9090. One outcome of this for me is that I will now test the staging server by running it this way (from bash): SUPPRESS_SITEROOT=1 ./start.bat so that SiteRoot translations are disabled. -- Fred Yankowski [EMAIL PROTECTED] tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA ___ 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 )
Re: [Zope] LoginManager dlpierson example
I just realized that I responded in terms of a PythonMethod when you asked about a PythonScript. My ZClass functions for my LoginManager subclass are all PythonMethods, yet to be converted to Python Scripts. My 'authenticate' method takes (self, password, request) as parameters and has for the function body only return password == self.password I suspect that an equivalent PythonScript will need to take password and request as parameters (not so sure about 'request') and will have a body like this: return password == container.password Ah, what the heck...

Re: [Zope] porting from Python Methods to PythonScripts in 2.3.0; LoginManager too
After browsing the Zope-dev list (I guess that's _yet another_ list I need to follow) I found a note about creating the 'access' file manually with zpasswd.py. After doing that, LoginManager seems to come up cleanly in Zope 2.3.0. And now I can see that my Python Methods come in broken, apparently because they depend on the PythonMethods product that I didn't carry over.

[Zope] porting from Python Methods to PythonScripts in 2.3.0; LoginManager too
I just installed Zope 2.3.0 and I'm planning how to port my sites from 2.2.5. It looks like I'll have to: + Copy over the Products I installed, _except_ + Don't copy over SiteAccess and PythonMethods. + Delete the PythonMethods product from the Control_Panel/Products management folder. Will I have to manually convert each existing Python Method to a PythonScript, or are they essentially the same type? I haven't been able to test what happens yet, because all my existing Python Methods relate to LoginManager and I haven't been able to get the LoginManager product to initialize correctly in 2.3.0. I followed the first two steps above and copied over my data.fs. It comes up cleanly except for an exception while loading the LoginManager and some ZClass problems for ZClasses that depend on LoginManger. The exception is this: -- 2001-01-29T16:57:02 ERROR(200) Zope Couldn't import Products.LoginManager Traceback (innermost last): File E:\PROGRA~1\Zope230\lib\python\OFS\Application.py, line 530, in import_products (Object: string) File E:\PROGRA~1\Zope225\lib\python\Products\LoginManager\__init__.py, line 1, in ?

There's nothing in my environment that mentions Zope225, and I dumped sys.path late in z2.py and it looks fine. I tried deleting the LoginManager product from the management interface and restarting, but the same exception occurs.

Re: [Zope] Did I miss some major change in Z SQL Methods ?
I missed the original message, but I'm trying to do something similar -- use Python Methods rather than DTML -- and I found one critical difference just today. Here's an example: I've got an SQL Method called 'select_item' that takes 'item_id' as its only input parameter. I've got a DTML Method 'form_action' that has 'item_id' in its namespace by virtue of being posted from an HTTP form. When I would invoke the SQL method from DTML I could do just and the SQL method would get the item_id from the DTML method. But when using a new 'action_script' Python Method (PythonMethod 0.1.7) I have to pass that item_id explicitly from the DTML and action_script itself has to call the SQL method like so self.select_item(item_id=item_id) I don't know why the explicit parameter passing is needed in the latter case (DTML to Python Method to SQL Method) but not in the former (DTML to SQL Method). I'm sure I'm missing some trick. In fact, this aspect of Zope -- when values are passed explicitly and when not -- is a major confusion for me. (And anyone who responds about "Zen" deserves to have the size 12 boot applied.) On Mon, Jan 29, 2001 at 09:28:17AM +1100, Curtis Maloney wrote: > The SQL Method works fine.

[Zope] Python Methods can't "construct literal dictionaries"?
I'm trying to create a Python Method, using PythonMethod 0-1-7, that
validates a set of form values before updating a database. I planned
to return any/all errors as a dictionary keyed by the errant field
name. But statements like this in my Python Method
input_errors = {}
input_errors['password'] = "password must not be empty"
...
return input_errors
result in the following error when I try to save the change to the code:
Error Type: Python Method Error
Error Value: Forbidden operation STORE_SUBSCR at line 3
What's up with that? I can't create dictionaries in Python Methods?
I must be missing something. Is there some way around this?

Thank you for describing the transformation rules in detail. With those I can mechanically create the same acquisition expression that you get. Working some further examples with this knowledge [and how can I use this knowledge to make mo' money?], I find that given a containment tree like this: a --> b --> c \--> x --> y the access path a.b.c.x.y results in a search order of (y, x, a, b, c) Evan Simpson wrote: > Trying to control or predict the exact search order for any but > the simplest acquisition trees is a dangerous game.

[Zope] SQL-based LoginManager and subtransactions
I haven't been following this discussion, but it sounds like there's the potential for SQL operations performed by LoginManager to interfere with other SQL operations such as logging uploaded files, in the case where the database system does not support nested (sub-) transactions. Correct? If so, would it help to create a separate database access object, and therefore separate connection (I think), just for the use of LoginManager? Or could this cause some deadlock between the LoginManager and other connections? I'm quite interested in potential problems here as I plan to use PostgreSQL with LoginManager on my sites.

[Zope] LoginManager, can't get past login form
I've installed LoginManager exactly (AFAICT) according to <http://www.zope.org/Members/dlpierson/sqlLogin>, and when I try to access the protected folder I get the login form, but when I enter the username and password into that form and submit it, I just get the same form back again. I've tested the SQL Methods invidividually and they work fine. I'm at a loss as to how to test the other components: ZClass, DataSkin, etc. I've tried running Zope with -D and -M, but nothing in the few trace messages indicates any problem. The username I inserted into the SQL database does not match any Zope username in the (standard, top-level) acl_user folder for the site. Does that matter? I've spent several hours looking over the ZPatterns Wiki pages and the various LoginManager web pages, and I'm starting to understand the mechanism involved in LoginManager, but I don't understand it well enough to know where I could put in a breakpoint that would help me understand why login is not working.

Can anyone help me understand what's going on in the last example of the main "Acquisition" document, <http://www.digicool.com/releases/ExtensionClass/Acquisition.html>? I think I understand how the various "complex expressions" relate to the equivalent expression in terms of the '__of__' operator, except for the very last case, "a.b.c.x". I just can't follow why the equivalent expression isn't x.__of__(a).__of__(c.__of__(b.__of__(a))) rather than the more complex answer given: x.__of__(a).__of__(b.__of__(a)).__of__(c.__of__(b.__of__(a))) When I run the test cases given in the document I see that the latter does match the behavior, but I find that baffling. In particular, why is the effective search order x-a-b-c rather than x-a-c-b? It almost looks like the effective search order could be described as "up through the containment heirarchy, then down through the remaining acquired path", but I'm not at all sure if that's a valid generalization.

Re: [Zope] Zope Book Beta
I agree completely that the Zope Book beta will get more reviewers, and better feedback to the authors, if it is available as PDF. The authors of the "Planning Extreme Programming" book made their draft available as a PDF well in advance of publication and got lots of thoughtful feedback as a result (based on what I saw on the XP email list). Here's a blurb in the "To Reviewers" section at the very beginning: Feel free to pass on this draft to anyone who might read it and comment. We aren't terribly worried that you will use the text in its current form and not buy the book when it comes out.

It failed for me the very first time I needed it, when I tried to integrate web pages created by the Web Studio tool into a larger Zope website. Web Studio (ack, phooey) creates a main index.html that uses Javascript to redirect to another page that acts as the real entry point. That Javascript code gets confused when loaded via as above. I resorted to doing the following instead: So now it takes two redirects to get to the real page, darn it. The above _could_ redirect straight to the real entry page, but exact knowledge of which page that is belongs to the subsite, not in my code. And it turns out that the subsite _has_ changed its entry page since I set up the above code. With Zope, simple things are easy, but slightly complex things tend to be hard. It's a weird learning/technology curve and I sure hope it flattens out soon... I've done a lot of website programming in PHP, Java, Perl, and AOLserver/Tcl -- none of those seem to have Zope's complexity at the point of creating simple database-backed websites. Zope doesn't even have a decent self-registering user login system out of beta yet.

[Zope] incorporating generated sub-websites within a Zope site
I'm looking for suggestions about how to manage a Zope website that hosts some subsites created by tools outside of Zope. Here's the situation. I'm working on a community website (batavians.org) for a small city (Batavia, IL) where I want to allow various non-profit community organizations to manage their own subsites. But the very first test case is proving to be a problem because the manager of the subsite is using web page development tools that seem to make it hard to integrate their subsite with the rest of the site. They can FTP their files up to the Zope server (which I configured to use port 21 for FTP) and their work is accessible just fine given a small "glue" index_html object that bridges to their internal main page. But I got blocked when I tried to add a standard page footer onto their pages. Actually, I was able to add a dtml-var element to pull in a standard footer via acquisition and that works, but the manager of the sub-website has no way to pull that change back to her working version of the subsite. It seems that the lightweight "Web Studio 2.0" tool she's using has no FTP-download function at all. Not only that, it has no way to view/edit HTML at all! It's only possible to edit using a WYSIWYG design view (AFAICT). So she can't merge in the change even if I tell her exactly the HTML code to add. OK, this problem is largely the result of the crappy web-design tool she's using, but I really have no control over that. The subsite manage/author doesn't know HTML and would be completely helpless with Zope's "through the web" editing interface. A better tool such as Dreamweaver would at least allow her to download files and/or edit HTML directly, but that's moot in this case. Even with Dreamweaver I think the DTML tags would be invisible and hard for a non-programmer to deal with. (Not only that, Dreamweaver refuses to open files that don't have an extension, so it won't open index_html for example.) So what alternatives do I have? Is there some way that I can set up a filter such that every page of her subsite goes through the filter before being sent out to the browser, allowing me to tack on a page footer on those pages? I'm sure Zope has such a mechanism, but I don't know where to look. Even with such a filter I'm not keen about having to parse her pages (which are/should-be each a complete HTML document) in order to insert a footer line in the right place. What other schemes should I consider? -- Fred Yankowski [EMAIL PROTECTED] tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA ___ 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 )

Thank you both for the help. File objects are just the ticket (but it turns out that Image objects work nearly as well).

Re: [Zope] Black Magic
Evan,
The information you just provided about the DTML Method "call
signature" and the like is very useful. Is this kind of reference
material written down somewhere in a guide/how-to/wiki/...?
I tried to figure out the call signature of a Python method by having
the called function use just "(*varargs, **kwargs)" as formal
parameters, but the inscrutable mapply() function seems to thwart that
effort as mapply() adjusts the function call according to what
parameters the called function (or callable object, ...) expects.
Very weird. Is there some document that covers the how and why of
mapply()?

[Zope] one external method calling another; what possibilities?
I'm using some example code that defines an External Method to process a form. That External Method calls another utility function to log some data. I'm not quite sure what choices I have for creating that utility function, so I created another External Method for it. Both functions are in the same Python source file in the Extensions folder. Anyway, the main external function calls the utility function like this: self.function2(arg1=valuex, arg2=valuey) I expected that function2 would have to be defined like this: def function2(self, **kwargs) but it turned out that that fails at runtime with a complaint about a mismatch between the number of arguments sent and expected (0 and 1, respectively). The following does work: def function2(**kwargs) So, why isn't function2 called as a method function? Was there some better way I could have implemented function2, rather than as an external method? Where is reference documentation on External Methods?

Excellent, that did the trick. Thanks! And now, after the fact, I see that the CHANGES.txt file mentions this technique. RTFM on me. I'm glad to have SiteAccess. In combination with the Apache ProxyPass method <http://www.zope.org/Members/anser/apache_zserver/> it's been working well to host several domains from the same Zope/Zserver instance. Very cool.

[Zope] trouble with SiteAccess; can't manage subtree mapped to inaccessible domain name
I set up SiteAccess 2-0-0b3 on Zope 2.2.2 so that two virtual hosts front-ended by Apache map to two different subtrees in Zope. That worked OK until the local DNS server lost the entry for one of my domains. I'm working on fixing that (it's out of my hands) but I find that in the meantime I can't even get to the corresponding Zope subtree in manage mode! I think the SiteAccess object I created is still mapping URLs to the domain name which now fails to resolve. How do I get out of this jam? I tried deleting the Products/SiteAccess folder, restarting Zope, and deleting the SiteAccess product from the Control_Panel/Products view, but now I'm getting an AttributeError when I try to access the subtree that has a SiteAccess object. Since I can't get to that tree, I can't figure out how to delete that object.
