You don't need to be a highly-skilled programmer in order to use Zope, but some programming background (particularly object-oriented programming) will be extremely helpful.

Now, Zope's original appeal to me was using the graphical interface provided by the ZMI to create a collection of objects which if you wire them up correctly will become an application, a view that I think is supported by the Zope Book. Yeah, me too. Turns out it's not such a hot idea after all. :) Disk-based products is the way to go (often just called packages in Zope3). However, this view, and what I've read about Zope 3 seems to indicate that this way of doing things is deprecated. Am I correct here? Particularly, if I am building an app that I think I will want to add extra functionality to after it has been installed and is in use, is this a particular reason to avoid developing with ZMI? Yes, that's a good reason to avoid it, because upgrading becomes problematic. Normally you want one development site and one production site, and you want to develop the code on the development site and then move it to the production site. But when the code and the site is the same, this becomes trickier. Now, if the answer to all of that is yes, then I think that steers me away from the need for TTW development (TTW = Through The Web = ZMI, yes?) Yup. I like the sound of this a bit better - just keep records in one place. So, if I've followed, I let the the house knows who owns it, and if I go to a certain owner's page and want it to give me a list of all the houses she owns, it would do a search through all the house records to see where she's mentioned.

I think we (the Zope community) should try to be clearer in telling newcomers what the 'entry requirements' are. My preference is to lie about the complexity. Newcomers are welcoming it much more then. Because if you say it is easy people will blame themselfs if they get stuck and to avoid embarrasment they will try a little harder. Try giving someone a logic puzzle and say it's dirt easy, it'll take you 2 minutes and they'll try really hard. If you say don't bother because you need a basketballsized brain to do they will give up and neither learn nor attempt. Let's keep the fluff around the meat welcoming.

Why should Zope be just as easy? Because Zope is hard. You can make some great sites/applications with Zope but for all except the very simplest you need . advanced understanding of html and xml or . a thorough grounding in programming principles or . a working knowledge of Python - and preferably all three. Whilst Zope can be used for developing extremely complex sites, that shouldn't preclude it as a development tool for simple sites. I think expertise only develops through extended usage of Zope, but there is just so much to learn, although I don't see a need to be an expert in numerous fields before touching Zope. Most (not all) of the people who hang out here have all three of these skill sets, and like many skilled people, they find it hard to understand that the skills they have seem arcane to beginners. You should also understand that nobody (AFAIK) is 'them' with an interest in making Zope easy and helping you. You depend on the kindness of strangers, so politeness and gratitude pay. Yes, I am aware of this. I also think that this list is not really appropriate for newbies, but in the absence of an alternative, this is where I ask my newbie questions. In addition, Zope is heading fast into even less friendly territory. DTML, which is technically 'mucky' but reasonably easy to grasp for non-programmers, is increasingly deprecated. Through-the-web editing likewise. I'm not saying these trends are bad, just that they are happening, they make the learning curve steeper, and that they lock out almost all casual users unless they have the skills noted above. The alternative in the Zope world is Plone, where you can get a site up and rolling in very little time (as long as you are happy for it to look and operate like almost every other Plone site on the planet). I looked at Plone but it is way too slow for the server I'm using. Besides that customisation looks like another learning cliff. or there's PHP, where the communities are probably more newbie-friendly and there are loads of tutorials. I'm sufficiently aware of Zope to know it provides a far more comprehensive build environment than PHP ever will and I would like to adopt it as my platform of choice, but it would be nice if the ZOPE support community was as newbie-friendly as the PHP crowd. Loads of tutorials and worked examples would be nice too. Reading a manual is no substitute for being shown how to build a web page using ZOPE and just reading through dozens of isolated examples of ZPT techniques makes progress very slow. I would much rather see a tutorial which starts of with a relatively complex but easily reproducible template which creates an interesting page, but then proceeds to de-construct what it does and how it does it. or you could decide that Zope does some stuff which you must have, in which case David H's stereotypical response If you spent more time just *learning* Zope and HTML, etc and less time rationalizing your lack of progress everyone would be happy. is appropriate. I only need to rationlise it when people constantly keep telling me to read the Zope Book as if that is the solution to everything.

I know a lot has been said since your original query, but re-reading it I was surprised that no one had asked a fundamental question: - If the data is structured in nature and fits the relational model well (e.g. is well defined), why not use an RDBMS for the data, and Zope/Plone for the UI? I do full-time development of web-based RDBMS applications in Zope and Plone (MS SQL and Firebird), and I have the following observations: - - By putting database-related complexity in the database, where it belongs IMHO, you may find (as I have) that the complexity of what you need to accomplish in Zope is reduced to the point where the ZMI approach is entirely appropriate. - You will find yourself working very hard to implement a relational database in the ZODB, compared to interfacing to an RDBMS.

Changing the name of properties isn't that easy, you'd have to write a conversion function or script that runs over all the instances and takes the value of the old property and put's it into the new name.

RE: [Zope] bytecode cache?
Well, as far as I know, bytecode is generated by the marshal module. And marshal can only precompile simple data types and code (classes, functions). So objects (class instances) can not be byte compiled. But I may be wrong... However, I had a funny idea too... I have been wondering about using marshal in ZODB instead of pickle, I mean, we only store object's states there, and as far as I have been investigating object states are simple python types that could be handled by marshal... But I am pretty sure I may have missed something that makes this completely impossible to achieve. It's just that, even using the highest protocol in pickle, serialization and deserialization of simple python types is much faster with marshal.

[Zope] Re: ZopeZoo
Hi John! John Poltorak wrote: In my quest to get to grips with the basics of ZPT I eventually stumbled across ZopeZoo which I found very useful. Looking at it again, there seem to be several variations of the same examples. I used this one:- http://www.plope.com/Books/2_7Edition/SimpleExamples.stx#2-10 This one is the latest version and as soon as the 2.7 edition (or maybe it will become the 2.8 edition) of the Zope Book is done it will replace the 2.6 edition on zope.org. This chapter is not finished jet. The last part is just copied from the 2.6 edition and doesn't work with the rest. but find there are a couple of variations here:- http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/SimpleExamples.stx This one is the last 'official' version, but I would not recommend to use it. http://www.zope.org/Members/jwhitener/zopeZoo_2_6 The 2.7 rewrite is based on this text, but while this text is a 'stand alone' tutorial, the book chapter builds on top of the previous chapters. Is there a definitive site for ZopeZoo? And is there a followup anywhere? I found I was getting the hang of it but could have done with a part two to show how to incorporate various divisions such as columns under ZPT. The guest book example has to be converted to ZPT anyway, but the highest priority should be to *finish* the latest edition, not adding new examples.

Re: [Zope] automagic reindexing of objects
hi all!
as i had time to look at all the stuff, i realized, that i'm
getting closer, but this is not exactly what i wanted...
as i can see from the path, one has to call:
beforeCommitHook(method, **args, **kwargs)
on each transaction, correct?
this is contrary to my idea of everything doing it's work automagically.
what i want is a kind of callback to each dirty object, something like
this:
class Transaction(...):
def commit(self, ...):
# insert this:
for object in self._objects:
try:
object._before_transaction_commit()
except AttributeError:
pass
# rest of original commit() follows...
could this impose any unforseen behaviour?
btw: what version of the two following is better (i.e. faster and more
elegeant, i do python coding since abt. 6months only...)
try:
object._before_transaction_commit()
except AttributeError:
pass
or
hook = object.get('_before_transaction_commit', None)
if hook: hook()
another question: is it hook() or hook(object) in the previous line?
i never know if the self parameter has to be passed in if not called
as self.method() - are there any (simple) rules?

It is impossible with ZODB 3.2 (unless you patch

The CPSCompat module of CPS has monkey-patches that backport this from
ZODB 3.4, among others, to be used in Zope 2.7.

Re: [Zope] automagic reindexing of objects
Have a look at how CPS uses this hook to delay indexing to the end of
the transaction.
Code is at http://svn.nuxeo.org/trac/pub/file/CPSCore/trunk/
IndexationManager.py
Then in all objects for which we want to delay indexing, we replace
the reindexObject() method with:
def reindexObject(self, idxs=[]):
Schedule object for reindexation
get_indexation_manager().push(self, idxs=idxs)
And the IndexationManager calls _reindexObject at the end of the
transaction.
This is done for instance in http://svn.nuxeo.org/trac/pub/file/
CPSCore/trunk/ProxyBase.py

RE: [Zope] bytecode cache?
I have idea about bytecode cache in Zope, it is possible to implement? What I mean: python scripts (in ZODB), DTML documents/methods, ZPT will be bytecode compiled in similar way like ordinary .py scripts into .pyc and then run much faster than noncompiled ZODB objects. I think that it should have significant speed improvement. ... or I am totally out? Python scripts already cache a bytecode representation (or at least they did last time I looked - its been awhile).

Re: [Zope] Traversal question
I have never used traversal into zsql methods simply because I don't want to expose geeky things like employee_by_id to the user. People should be able to find out what you call your ZSQL methods. My suggestion is to consider a more controlled solution. About having request variables in the URL I suggest you download and study the code of the IssueTrackerProduct. Look for a method called get_environ and __before_bobobase_traverse__ Then one gets URLs like this: http://demo.issuetrackerproduct.com/ListIssues/sortorder-urgency/reverse-true which is translated in get_environ() to http://demo.issuetrackerproduct.com/ListIssues?sortorder=urgencyreverse=true On 6/22/05, David Pratt [EMAIL PROTECTED] wrote: I have gone over the zope book to see what I can do about calling a sql with a form and getting three additional parameters in the request and am wanting this to get better looking urls that calling the parameters directly in the url.

Re: [Zope] ZPT tutorial
I'm sufficiently aware of Zope to know it provides a far more comprehensive build environment than PHP ever will and I would like to adopt it as my platform of choice, but it would be nice if the ZOPE support community was as newbie-friendly as the PHP crowd. Loads of tutorials and worked examples would be nice too. Reading a manual is no substitute for being shown how to build a web page using ZOPE and just reading through dozens of isolated examples of ZPT techniques makes progress very slow. I would much rather see a tutorial which starts of with a relatively complex but easily reproducible template which creates an interesting page, but then proceeds to de-construct what it does and how it does it. just in case you've missed it, open zmi add Zope Tutorial go through it write up your exp for other new users jumping in! hth or you could decide that Zope does some stuff which you must have, in which case David H's stereotypical response If you spent more time just *learning* Zope and HTML, etc and less time rationalizing your lack of progress everyone would be happy. is appropriate.

Hi Jonathan. Thank you for your reply. The ? = don't make for very friendly or future proof urls.

Re: [Zope] Traversal question
Hi Peter. This is very interesting. I will look at the code! I agree with you about exposing the zsql methods and also I tend to use a naming convention for zsql methods might even stick out more.

With HTTP1.1 its possible to change keepalive-timeout. 'keepalive' only refers to the lenght of time that the browser-webserver connection stays open between the completion of one request and the beginning of another to the same server. The behavior we are discussing here is that IE (or sometimes Apache in the middle) is configured to time out a single request after a period of time; Mozilla and derived browsers don't do that by default. MS says: By default, HTTP 1.1 is enabled in Internet Explorer except when you establish an HTTP connection through a proxy server. When HTTP 1.1 is enabled, HTTP connections remain open (or persistent) by default until the connection is idle for one minute or until the value that is specified by the KeepAliveTimeout value in the registry is reached. You can modify HTTP 1.1 settings in Internet Explorer by using the Advanced tab in the Internet Options dialog box.(http://support.microsoft.com/default.aspx?kbid=813827) I interpret this so: You have to use HTTP1.1 .

Hi all:
Thanks to Paul Winkler for his FWIW.
Thanks a lot to Michael Dunstan for insists in the fact of
response.redirect('init2-second-half'), because like he perhaps imagined I
do the return init2-second-half instead of redirect.
I test with the redirect and the error disapear, for now ; )

Hi Leticia,
Just double check that you are redirecting from the init2-first-half
to init2-second-half. Using something like the following in init2-
first-half::
response.redirect('init2-second-half')
rather than directly calling init2-second-half.

Re: [Zope] Re: Problem with keep-alive timeout
If you really need handle an arbitrary processing time. You might need to separate the request submission from the processing, and the processing from the results display. Roughly the way it would work would be like dropping your laundry off at the cleaners. You bring in the dirty clothes and then get a ticket back and an expected due date. You come back around the due date. Very likely your clothes are ready and when you present the ticket you receive your clean clothes. Occasionally, you get told that due to some sort of delay your clothes aren't ready and you are given a new due date. A similar sort of thing could be done with a long running request. The initial request gets bundled into some sort of job object, and a Job ID is returned and a please wait page. That page can have a delayed redirect to a results page which can take a job ID, determine if it is complete and display the result. Meanwhile, you have an entirely separate process (perhaps run by the Scheduler product http://cvs.zope.org/Products/Scheduler/ that takes jobs, processes them and inserts its results. Of course, I'm leaving off a lot of details here. Off the top of my head, I can think of the following issues that I'm just glossing over. I'm sure there are many more: You don't want job IDs to be easily guessable or forgeable, or people might be able to steal each others laundry. You have to think about what you do when jobs get abandoned, (eventually the clothing racks get full) Finally, (and thankfully one that I don't have a laundry analogy for) you may need to concern yourself with the fact that the Zope user that is doing the job processing is different than the one doing the requesting. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Re: Problem with keep-alive timeout
A possible work-around: Set up your web page so that it has two frames: the main frame (visable) invokes the long running zope script; and a secondary (hidden) frame uses a javascript routine (running on a timer) which queries a no-op zope script. This should stop your browser from timing out. Ugly, but it should work.

Tim, subtopics appearing from nowhere could be due to a Zwiki upgrade. If you are indeed looking at a wiki page, the Zwiki release notes and admin guide will explain.

Re: [Zope] TypeError: Cache values must be persistent objects.

I'm trying to develop a filesystem-based Product (here 'ABCD') and
unless I remove the ABCD folder from my Products directory, I get the

Is it possible to determine what's causing the problem? After multiple

objects of type ABCD Content. But still the problem persists (no pun
intended).

Looks as if you had changed the class structure:
An object that formerly was persistent (when it was stored
in the ZODB) now gets a class which is no longer
derived from Persistence.
Note that the ZODB identifies the class of an object
by modulepath, classname. You should ensure
that the class identified in this way always derives
from Persistence (and that is exists).
To find out what object this is, you catch the error and
look at object.__class__.

TypeError: Cache values must be persistent objects.
As we see, catching is not necessary.
The traceback is enough ;-)
Products.ABCD.XML_File lost its Persistence inheritance...

Re: [Zope] bytecode cache?
Jaroslav Luke-Bš wrote at 2005-6-22 14:51 +0200:-A I have idea about bytecode cache in Zope, it is possible to implement? What I mean: python scripts (in ZODB), DTML documents/methods, ZPT will be bytecode compiled in similar way like ordinary .py scripts into .pyc and then run much faster than noncompiled ZODB objects. I think that it should have significant speed improvement. All of these objects are (in some way) already now byte compiled. But only some of them store the compilation result inside the ZODB (ZODB based DTML objects and PythonScripts do). Thus, on initial access, they need to be compiled. Further access already finds the compiled code and can skip compilation. However, there is potential to reduce startup (!) time by storing the compilation result. That is the purpose of my CompiledExecutables http://www.dieter.handshake.de/pyprojects/zope When you look there, you find a note currently broken. That is because the current version only works with our own slightly modified (fixed :-) ) Zope. It causes an infinite loop when used with a stock Zope. Someone reported the problem and I think I have a fix. I asked the reporter to try it out and report back. But never got an answer... maybe, because my eager spam filter did not like his mail service provider (all providers that relay spam and do not react on my complaints are banned to send me any more emails). If you are interested to take over and check my fix, let me know (it usually is better not to try to contact me privately (-- eager spam filter) but to send Zope related messages and questions to the mailing list). -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Nikko Wolf wrote at 2005-6-21 16:13 -0600: ... But that begs the questions + why didn't the stack backtrace give the problem ID? It would not have helped: the problem was not an individual instance but a class problem... Your problem is of a rather rare type (few people remove Persistence from the inheritance chain for persistent objects). In general (not in your special case), the id cannot be determined in case of loading problems. More importantly: The error was detected in ZODB, a component used by Zope but also externally. And ZODB cannot expect all its persistent objects to have an id (indeed most, even in Zope, do not!). + if 0x28b5 can be deciphered as an ID, how? Neither this nor your original message tells us what the 0x28b5 should be ;-) It probably is the object's oid (object id), in hexadecimal form. It is useful, to load the object from ZODB in an interactive Python interpreter to analyse the problem more easily (i.e. use pdb.pm to analyse all objects relevant for the exception). + why didn't the Find locate the broken instance? (it *might* be since I've created about 15 different portal_types, and the ABCD Content wasn't really what the offending ID was). Because, it would have died (same exception as reported in your original message) when it had tried to access the object. Do not expect to get realiable results when you did something that prevents objects to be loaded from ZODB ;-) + is this a common problem with file-system (or ZClass) products? Few people remove Persistence from the inheritance chain of a class once they have stored persistent objects of this class in the ZODB... -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
