Re: [Zope] why DTML confusing
First Simon, thanks for your message. Yours is one of the most articulate explanations I've seen on this topic. Simon Michael [EMAIL PROTECTED] writes: > Irene Barg <[EMAIL PROTECTED]> writes: > [examples of DMTL confusion...] > > It is confusing.

Most of us probably have that down solid, so we tend not to think of it in the context of "skills needed to master Zope." But whether it's wrapping data in an HTML table, or how to create dynamic CGI forms, mastering the integration of HTML and DTML is a critical skill that some apparently find difficult. (I've seen HOWTO's for it...) > - unfortunate reality #1: you have to use "" expressions to do any > kind of comparison, so you are pretty much forced into dealing with > these two worlds right from the beginning. That's fine, but in the interests of good will and sanity, Zope should probably have a big fat warning label saying "DO NOT VENTURE HERE IF YOU DO NOT ALREADY KNOW, OR PLAN TO LEARN PYTHON." I did know Zope was written in Python. I did not expect that I would have to learn it. Maybe that was stupid on my part, but that's what I thought. > Still, entering the python world would normally be a good thing, since > syntax there is simple and consistent.

Yes, it would help a lot. _[] is about as non-intuitive as you can get, especially after mixing in all the single and double quotes. Sure, if you understand python and how DTML wraps around it, it all makes sense, but that's a pretty narrow market and DMTL simply doesn't need to be that obfuscated. If the intended market is simply "people who grok Python", then there's really no point in something as Point n' Click n' GUI as Zope is. I certainly don't have all the answers, but it seems a simple matter to allow both sequence-index *and* sequence_index - i.e., create underscore equivalents alongside all the legacy "hyphen" variables. If I recall, I've even seen some user-contributed patches on this list to do just that. That's just one example of something in Zope that's "too difficult" screaming for change. But one of the practical advantages of making that kind of change is that the people who contribute their valuable time to help the newbies (and not-so-newbies) on this list won't spend quite so much time saying Try this: That's an awful lot of weird syntax glue just to walk a list and set a value based on values in the list. If someone asked how to do that on a Perl mailing list, they'd be RTFM'ed and run out of town. Maybe that's not an entirely fair comparison, but still, how much of that syntax nightmare might be avoidable? I really don't know enough to say. Obviously *everything* has to be wrapped in something that at least distinguishes DTML from HTML. How quickly or deeply (or just *how*) one should get into python after that is another matter. Zope reminds me of NT in some ways (except that I *like* Zope). Zope, like NT, presents this illusion of friendly, easy learning curve, straight-forward "get the job done and move on" philosophy. At least that was my first impression. Then reality struck and I'm still recovering! What keeps me working with Zope is not so much what Zope is, but the promise of what it can be. (And the hope that when I'm finally a Python ace and understand the Zope source code from nose to tail, I'll be ready to work in DTML ;-) -cw- -- ~ Charlie Wilkinson - [EMAIL PROTECTED] - N3HAZ Parental Unit, UNIX Admin, Homebrewer, Cat Lover, Spam Fighter, HAM, SWLer...

Hi Morten,
Yes. It's acting as if those little boxes were not checked! :) As I was
replying to Jeff in a prior message, the mystery goes deeper. I grabbed a
fresh copy of the latest CVS version, built it, set a superuser password
and ran it. I then tried to visit the default index_html "Welcome to
Zope" page and was presented with a BASICAUTH type login box. If I
explicitly set anonymous View permissions for the index_html (Welcome
to Zope) page, then I get in with no login as expected. That isn't
normal is it? Root folder objects would appear to be having the same
security setting acquisition problems as I was finding previously with
sub-folders and LoginManager.
I realize I'm on the bleeding edge of Zope running the CVS version,
but I heard the 2.2.3 version is due out RSN and figured maybe a little
"new version" pain now would be easier than upgrade pain later. I'd sure
rather be saying "Here's a patch" than just "It's broke", but alas I
don't grok Python that well yet. ("It's broke" still offers *some*
value, right? :-)
To the Zope developers: It seems pretty clear that Zope v2.2.cvs is
broken in regards to security settings acquisition. Should I post to
zope-dev, or is there already a sufficient awareness/understanding of
the problem?
Thanks,
Charlie

This is > consistent. Thanks for your response Jeff. It seems we are in agreement. The scope of an acl_users folder needs to include its siblings and parent folder. The only logical alternative I can think of is if the functionality of acl_users, LoginManager, or whatever, was provided by some modular component of the parent folder itself, instead of being represented as just another object _in_ that folder. Anyway, I did a sanity check against v2.1.2 using these exact steps: 1. Create an access_test folder with user folder and user interface. 2. Navigate to security tab of access_test. 3. Create new role "User", and allow "User" to View Objects and Access Contents Info. Bar access by "Anonymous" by turning off "Acquire Permission Settings" for View Objects and Access Contents Info. 3. Create user "joe", password "blow", with role "User" 4. Bring up new browser window, enter the URL for access_test. In that scenario, joe can view anything within the acl_test folder, while anonymous users cannot, due to the objects within that folder acquiring their security settings from the acl_test folder itself. *That's* what I want! It's *not* what 2.2.cvs is doing. In fact it's even worse than previously described. After pulling down a completely new CVS image of Zope, I just happened to try visiting the root URL of the new site. Result? I was prompted for a password to visit the root (Welcome to Zope) page of a pristine, new Zope site. I think this must somehow all fit together. Unless there is something critical about the new security model that I have missed, it looks like there's a bug here. > If you have 50 or so objects, and setting permissions is the obstacle, > simply write a Python Method (or DTML, if you prefer) to iterate over the > 50 and tweak them.

As I think you indicated above, the type of security/acquisition model that seems to be in place for 2.2.cvs poses far more serious problems (i.e., needing acl_users *above* the root folder) than just setting permissions on a bunch of modules.

[Zope] Security and Acquisition
Greetings, I know this a very busy list, but I'm hoping someone can take a moment to address this. I had posted about this on Zope-dev because I'm running the CVS version, but no response. Also more research has yielded more info. I first discovered this issue with LoginManager, but the same problem occurs with standard acl_users too. First, 'Figure 1:' / (Root Folder) / acl_test (ACL Test Folder) acl_users (User Folder) index_html (Test Document) Now, referring to figure 1 (above :-), changes to security settings for the acl_test folder are having no effect on access to index_html. Only when I change the security settings on index_html itself, can I control access to it. So what this seemingly boils down to is that as of v2.2.whatever, an acl_users folder does not protect its siblings and their kids by acquisition of security settings from the parent folder. Instead, sibling objects must have their security explicitly set. Meaning that instead of setting permissions on the parent object and being done with it, one now has to set permissions for each and every sibling. In my case that's over 50 objects and I'm not done coding yet. Ouch! This *can't* be right, can it?

[Charlie draws a deep breath and starts out softly] I'm not a dummy. I've been a UNIX application developer and SysAdmin for ten years. Really goofy hardware too. Ever try and build Sendmail on a Pyramid MIS-4? For ten years before that I was an electronics repair technician.

This is despite the fact that I'm now stuck sending plaintext to everyone in our organization! My suspicion is that some well meaning but deranged Exchange SMTP gateway server is doing the conversion, as there's a meta tag that says the HTML generator is Exchange. I've tried talking to the people who run the servers, but they are clueless and keep saying it's something I'm doing. So I just try to avoid posting to the list from Outlook, but last night at the office I was (and still am) desparate. But now I'm home with Linux/Mutt. Yay! :-) Sorry you had to read that.

"Knight" once said: > > cw, > > Are you spawning additional threads by chance? Or just the threads that > Zope creates? No, I'm a Python newbie who doesn't know of threads yet, so this is just Zope threads working their magic. :-) Right now I'm just shooting for a simple network client as a proof of concept, though ultimately I need to take into account that the server this client is talking to is *cough* single instance and single threaded (i.e. only one client at a time). So what I really need to do for the long haul is set my client software up to hold a persistent connection and multiplex/queue the requests. I assume that means I'll need to rewrite my External Method interface as a Zope Product? Maybe I should try to grok one of the database connection products and model after that? The server is Rand McNally's Unix Resident MileMaker (URMM) milage calculation software for shipping, if you were wondering (what to avoid?)

[Zope] Arrrgh!!! *Weird* SQLSession problem
Ok, all weekend I've been chasing my tail. Now I scream for help... I cannot get SQLSession to insert values into the zsession_data table to save my freeking life. I'm not getting errors of any kind, just no inserted session data. However, the zsessions table shows the sessions being created, so that table is working ok. I mangled the SQL syntax for sqlSetValue, *then* I got a pg. error, so sqlSetValue *is* running, yes? I installed Logger and logged the values from sqlSetValue to the zope log. I cut and pasted those values from the log into the test query screen for sqlSetValues and when I submit the query it inserts just fine. At that point I can see the manually inserted values from session_test.dtml, so sqlGetValues is working. But if I try to insert values with session_test, they show up in the very next screen, but are gone thereafter and of course they do not show up in the database. I'm really at quite a loss here. I made sure to give SQLSession its very own ZPyGresQLDA connection. After beating on that unsuccessfully for awhile, I installed ZPoPyDA, and set SQLSession to use that, which of course didn't change anything. Here's the version particulars: Zope version: Zope 2.1.6 (source release, python 1.5.2, linux2) Python version: 1.5.2 (#1, Sep 17 1999, 20:15:36) [GCC egcs-2.91.66 19990314/Linux (egcs- System Platform: linux-i386 ZPyGreSQLDA 0.3 ZPoPyDA 0.5.1 PoPy 1.3.2 beta SQLSession 0.3.0 PostgreSQL 7.0.2 Other installed products (if it matters...): ZPyGreSQLDA Fortune Calendar Logger Photo ZPatterns Confera LoginManager SQLSession ZPoPyDA WorldPilot iTrack Mild rant: I've got a big, scary, and now behind schedule database-enabled website to build for a client. Most everything I've read, and even my earlier, simpler experiences with Zope have been fantastic. I've been going on to my client about how great Zope is, rapid deployment, etc, blah. So I committed, but after fighting with LM (It took weeks to get it working once and I have not been able to duplicate that feat since), a failed upgrade to Zope 2.2 (LM wouldn't work there yet(?), doh!), and now SQLSession... I'm *not* having an overall good feeling about all this. I'm even starting to get thoughts of retreating to Perl or learning PHP3 and never looking back. But I really want to get over what's probably mostly newbie learning curve & lack of docs and make this work in Zope.

However, I'm still getting an attribute error on __getitem__. I'm trying to figure out how namespaces get passed around in Python to see if there's an easy way to fix this. I've also found a workaround and pondered another: - pass ['Folder','DTML Document'] to optionValues the normal way, i.e.: ...and then simply use DTML Documents and *only* DTML Documents for stuff I want in the tree menu, primarily CGI forms, some of which might be dynamically generated. I guess if I smack into any limitations with DMTL Documents, I'll have a Document call a method. It's not ideal, but it seems workable enough. The other alternative might be to use ZCatalog with the Tree tag somehow. I think it might do what I need, but I haven't given it much thought. That said, I still think the idea you and Rik have been helping me with is the most "elegant", but I've got a big site to build and very little time. Would it be any easier if instead of a DTML Method I used an ExternalMethod as a wrapper/filter around objectValues? It's very frustrating, as I keep thinking there's *got* to be an easy way to fix this if I only had a half a Zope/Python clue. I'm already reading about as fast as I can!

[Zope] WorldPilot and UW-IMAP?
Greets, I'm experiencing an issue with WorldPilot not showing the body of messages that have attachments. I can only guess that this is because WorldPilot was designed for use with the Cyrus IMAP server and I'm using it on a stock RedHat system, which I presume sports UW-IMAP. I've searched around and not found too much detail about UW vs. Cyrus for WorldPilot. Can anyone enlighten me as to whether or not my problems are due to using UW-IMAP and generally whether it's worthwhile to suffer a Cyrus install, vs. a hack or patch to WorldPilot? I frankly don't want or need what Cyrus has to offer. I really like WorldPilot and I'm trying to push it on an office full of people, but you can imagine how thrilled they are about not being able to read select messages. They are starting to make noises about wanting to go back to Outlook now.

Use id. Not sure. Supposedly objectValues() returns "actual objects", and I assumed that using sequence-item would be something closer to that. The finer points of python are still lost on me, but I'm working on it. The bigger problem seems to be the namespace issue that Dieter was speaking of. When I tried your code, I got Attribute errors on __getitem__. It appears that Tree does not inherit the usual DMTL namespace.

[Zope] Fun with Trees
(I always wanted to be a lumberjack! :) After RTFMing and flailing at DTML all night, I'm about stumped. No pun intended. I'm trying to use dtml-tree to create a selective menu of objects based on whether or not the object has an "add_to_menu" property. I've pretty much figured out that I need a wrapper around objectValues that will filter out the objects that don't have the "add_to_menu" property. This wrapper would be called with dtml-tree's "branches" attribute. I'm trying to do this wrapper in a DTML method and I've gotten all the way to where I have to return a list of "actual objects", so says the DTML Quick Reference. Is there someone who could 'splain to me how to build a list of objects in DTMLese? Here's what I have so far (obviously not working): Right off the bat, Zope is giving me attribute errors about REQUEST, but I'm not sure how else to do a set(), other than with REQUEST or RESPONSE in front of it. When I ran it stand-alone, I was *not* getting attribute errors and *was* getting output that looked remotely like the guts of the desired objects. Spare clues anyone?
