I am not under any time constraint. Your case is complex and the answer is non-obvious. I think you will have to try to see. The best I can describe it is as a kind of expert system (but not AI) that needs to find the best workflow for a process, given a set of initial and final parameters. E.g. a 'capsule' of data must pass through many 'tools' or 'environments' to reach a desired output - something like a very complicated car wash. Let's say there are many tools that can be used at various stages in the process. I have estimated there are at least 500 tools as of now, and it is bound to grow in the future as newer tools are introduced. Existing tools will also have version updates. Each tool, on average, has at least 100 properties that define the tool. This kind of complexity and flexibility that your case has does lend itself well to the ZODB. But it is by no means impossible to do in a relational database. What you would need to do here if you did this in SQL is to have one table for the tools, and one table for the properties, and one table that for each tool and property has a value. This might be a bit complex to use of you use an ORM, but it should be doable. problem of 'matching' the tools for analysis. E.g. Tool A might have only three fixed rpms - 100, 200 and 500, but Tool B might have rpms from 20 to 2000. I'm not sure how I can construct a database without spelling out each number, as in the example above. Well, if you want to search for a specific RPM range it does get complicated, because then you probably want to store the RPM values as integers. And that means that you in the property table needs to have several columns depending on the value type. If the property needs text, you need to fetch it from the text column. If the property is an integer you need to fetch it from the integer column. If the property is a reference to another table, because it is a multi-select property with a limited set, you need to fetch it from a column for that, which in turn refers to another table with the actual values. This *does* get very complex very quickly. Of course, the ZODB has few such problems. Will the app be better served with a relational DB like mySQL or an Object database? After a lot of research I've guessed that my particular case might be better served with Python and Zope/ZODB. But I might be wrong? Maybe PHP+mySQL or Django is a better fit? First of all, find yourself a web-framework you like. Then use that. Most likely, that framework is going to limit you to using SQL. There are frameworks that don't specifically Pyramid integrates nicely with ZODB and hence gives you a choice. Then I would simply try to see if you are able to model the data in SQL at all, or if you dig yourself into unholy complexity. That should not take more than a couple of days of work to figure that out, if you concentrate on building a database and filling it with real or realistic data. If you don't dig yourself into a hole, the go with SQL, since that's what you know. If you do, try to build the model with ZODB and see of that works better for you. The ZODB might very well be the right choice here. But note that Zope is not. Zope was a trailblazer in the web framework world that's been around for 15 years now, and has as a result made some choices which turned out to not be the best ones in the long run, and accumulated a lot of cruft. There is work on fixing this, but that will take time, and the framework will be in a great flux during that time. As a result, Zope is not currently a good choice if you start a project. As languages go, Python rules. As web frameworks go, there are more Python frameworks than you can shake a stick at. I'd recommend either Django (because there are so many people using it, you will be able to find help ) or Pyramid (because it's really cool and supports ZODB well). //Lennart ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

Existing tools will also have version updates. Each tool, on average, has at least 100 properties that define the tool. Some of them have as high as 1000 unique properties. How familiar are you with OOP? What I mean is, when I read your high-level description of what you want to do, I imagine objects interacting with other. In your car wash example I see that, for instance. Or any kind of work-flow, which is what this sounds like to me. A state machine. Each tool is an object; it knows what its properties and abilities and possible states are and can communicate them to other objects and can accept and act on communication from other objects. In that way the objects interact with one another to do whatever it is you build them to do. I'm thinking of your car wash metaphor. In a car wash there are a variety of elements (objects) that communicate with one another to move the car through and to wash it as it moves through. Simple example: * mechanism that pulls or pushes the car through * mechanism that sprays it with water and soap * mechanism that scrubs and wipes and rubs it * mechanism that sprays it with rinse water * drying mechanism(s) These all need to signal one another so they do the right thing at the right time. Spray (or scrub or blow hot air) only when the car is in the right place for each. If some tools can be built by adding to/extending other tools, that is an object-friendly situation, since enhancing an existing tool to make another that you need saves you having to create all tools from scratch. In the car wash, maybe the different sized scrubbers used are all made by bolting together two or more of the smallest size scrubber. Maybe in parallel, maybe in series, depends on what is needed. Maybe the same scrubber controller can have different size brushes attached to it. In short, an object - tool - is code and data that interacts with other tools (other entities of code and data). An upgrade to a tool would involve changing the code and/or data that constitutes the tool. If that introduces some new way of interacting that other tools need to also know, then you add that to those tools also. Adding more tools means coding them. If they can be based on existing tools, so much the easier (and more object-appropriate). So that's some high-level information about an object-oriented approach to what I think your project is about. Tthe flexibility you appear to need as the system grows may be problematic for an RDB. And, my bias is OO, so perhaps someone who thinks in RDB-space can describe at high level how this would look in an RDB implmentation. cheers, John S. -- John Schinnerer - M.A., Whole Systems Design - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration j...@eco-living.net http://eco-living.net ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

Therefore, this information should be defined outside the program in way that the tool expert(s) can manage it. Which leads us to some storage solution, an RDB being the most common. Since, as I pointed out before, SQL most likely would not be able to do the tool selection alone, Python would merely load the data from the external source and create objects and expertise on the fly.

At a earlier stage Zope devels discussed for integrating ingres or another RDBMS natively into Zope - but this is not longer the case as there are many Zope adapters / integrations / products available for different major RDBMS like MySQL or Postgres. For the data structures where you have to handle large tables MySQL would be the first choice while oo data structures would preferrably go into your ZODB. I.e. we handle large amounts of user data records within MySQL while all of the web content objects or even complex shopping products are handled within ZODB - both within the same Shopping Cart application. This all depends highly from you data model. By theory you are able to handle both in just on of the DB solutions.

The approach I use is: zpt page - (one) Python Script - (some) ZSQL Methods - MySQL The zpt defines the layout of the pages, the ZSQL Methods retrieve the data needed and the Python script massages the data to make it suitable for the ZPT page.

The advantage of the relational approach is that it is a very well understood model and although different people will still come to different models there are sufficient objective guidelines out there (e.g., the normalization rules, and then criteria for when to denormalise) to help you along. Furthermore, there are lots of people in db-related forums that can help you. Also, RDBMS provides you with a standard query language, SQL, which plenty of systems and tools can use. In general, RDBMS gives you the safest approach to keep your data and not loose it when you need to migrate either the front-end or the back-end. This language is very powerful and can avoid you a lot of low level programming. However, plenty of people can not deal well with SQL because it follows a paradigm so different from the classic imperative programming. With SQL, you specify the what, with the other languages you specify the how. The advantage of the what is that you can do a lot of data processing in a few lines of code. The problem with the what is that because you don't know the how of it, you feel you don't have control and you are led to say the language is obscure or unreadable. However, even if you are not comfortable with the what (you have to try to know), you can still rely on an library like SQLAlchemy to keep you a bit in the comfort zone of the how. So instead of learning SQL, you need to learn the API of a specific library. Your choice. I recommend the first by far. The real main issue with Relational is that it is a highly structured data model. It allows you to keep high quality data but if you don't get it right soon enough in the development cycle, some later changes can have a huge impact in the application, requiring rewrites.

Perosnally, I would avoid as much as possible to put data in something like ZODB (I use it merely to store and manage the application). The problem with your specific case is that it does not seem to be a typical case of books and authors, which might be a risk for someone without experience. The issue Tool A might have only three fixed rpms - 100, 200 and 500, but Tool B might have rpms from 20 to 2000, is indeed tricky. I suspect in general the needs of your system will be too specific to be able to rely only on SQL queries. You would need to put a lot of intelligence in the data (really highly structured) and it might become unmanageable or not scalable. I guess you will need to put a lot of intelligence in the Python Script. So, the ZSQL retrieves the relevant tool data and then makes the tool choice. The knowledge of the meaning of the attributes is maintained in programming. I should say I am not totally sure the Python Script is the best approach here, in terms of management facilities. But Python is surely a very good language due to its readability. However, you might need to use External methods or a more typical file-system based Python approach. Or maybe you actually need to create a Domain Specific Language to encode the intelligence needed for your tool selection process. If your python code becomes repetitive, with patterns showing up, then a DSL might be a good approach, but this might be too much engineering for you at this stage. It looks like you are in a typical CIM scenario and I remember handling a similar problem 20 years ago. I vaguely remember at that time to use custom graph structures in C and the the intelligence was coded in Lisp/Scheme. So, there is a big range of solutions to try out :) If you have time, then the simple approach zpt page - (one) Python
Re: [Zope] Help in deciding approach to Web App
Thanks Fernando! I really appreciate the time and effort you have put in answering my query. My personality sides with Python but my hosting provider does not support Django or Zope. As you mentioned, if I have to use mySQL, isn't it better for me to go with PHP+mySQL - easier to learn and deploy? Can I just start out with a framework like Symphony instead? In the future I'll have to use either Python or C/C++ for my business logic and math. But the focus now is to get a prototype out, and if I'm doomed to change everything later I might as well start with the easiest and most obvious. Is this a viable starting point compared to what you have suggested? Or am I missing something? -Sareesh Date: Sun, 4 Dec 2011 13:28:36 +0100 From: ferna...@cmartins.nl To: ays...@hotmail.com CC: n...@syndicat.com; zope@zope.org Subject: Re: [Zope] Help in deciding approach to Web App On 12/04/2011 09:52 AM, Sareesh Sudhakaran wrote: Thanks Niels.

Re: [Zope] Help in deciding approach to Web App
Aloha, Very briefly, from what you describe, it looks like you are dealing with large numbers of complex objects (your 'tools') that interact with each other - and with some other elements that are going through this workflow process? And a context for the process? ...not sure of that part... In any case, this looks (to me anyhow) like a very object-oriented system you are modeling so an object oriented approach and language would seem most suitable. Python is one reasonable language option; zope for the web publishing aspect of the project would fit well with that. I haven't worked with other OO languages enough to usefully compare. It also sounds to me like the web publishing is the lesser part of this...? That is, the workflow of interacting tools is the real 'app' here, a process which does not all get shown somehow on a web page...or does it? Or just the outcomes? LAMP platform is so common and cheap that it's all a lot of people know about. It can be used well, and, it is all too easy to make horrible hacks and Frankestein monster apps in PHP/MySQL. Meaning, a highly structured (yet powerful) OO programming language will support you in avoiding that. Also, for development (or just to explore if python+zope might meet your needs) you don't need any hosting, you can install python+zope on your development system and try it out. best wishes...

[Zope] help debugging a can't pickle error deep within a catalog reindex
hi, i'm trying to perform a ZCatalog.refreshCatalog() on a catalog with over 29,000 indexed objects. it churns for a good long time, and eventually fails with a long set of tracebacks, of which i've included a sample at the end of this message. i think i understand the gist of the issue... it's trying to write an object (probably a CatalogBrain) to the database, but this object's __dict__ contains a value that is of type instancemethod, which isn't allowed for persistent objects. the problem is that i can't figure out which specific objects are causing the problem. i've used pdb.post_mortem to get a debug prompt way down in the traceback, but the code goes in and out of C modules, so i'm missing a lot of what's happening. and when i interactively peek at the objects that are being indexed when the error happens, there doesn't seem to be anything wrong, and i can index the objects w/ no problem. i've even tried dropping the subtransaction threshold down to 1, so it will try to commit a savepoint after every object, but none of the objects being indexed seemed to have any problems. i CAN verify that the instancemethod that is causing the problem renders like this: bound method SessionDataManager.getSessionData of SessionDataManager at /session_data_manager even that hasn't proven enough for me to concretely identify the source of the problem, though. i've been working on this for a full day already, and am not sure how to proceed. does anyone have any debugging tips that might help me figure out what, exactly, is causing the reindex attempts to blow up? thanks! -r Traceback (most recent call last): File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/Products/ZCatalog/ZCatalog.py, line 296, in refreshCatalog self.catalog_object(obj, p, pghandler=pghandler) File /home/rob/topp/14000/builds/20080611/opencore/zope/Products/CMFPlone/CatalogTool.py, line 367, in catalog_object self._increment_counter() File /home/rob/topp/14000/builds/20080611/opencore/zope/Products/CMFPlone/CatalogTool.py, line 395, in _increment_counter self._counter.change(1) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/BTrees/Length.py, line 55, in change self.value += delta File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZODB/Connection.py, line 890, in register self._register(obj) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZODB/Connection.py, line 900, in _register self.transaction_manager.get().join(self) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/transaction/_transaction.py, line 273, in join self._prior_operation_failed() # doesn't return File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/transaction/_transaction.py, line 267, in _prior_operation_failed raise TransactionFailedError(An operation previously failed, TransactionFailedError: An operation previously failed, with traceback: File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZServer/PubCore/ZServerPublisher.py, line 25, in __init__ response=b) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py, line 401, in publish_module environ, debug, request, response) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py, line 202, in publish_module_standard response = publish(request, module_name, after_list, debug=debug) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py, line 119, in publish request, bind=1) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/mapply.py, line 88, in mapply if debug is not None: return debug(object,args,context) File /home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py, line 42, in call_object result=apply(object,args) # Type scr to step into published object.

Re: [Zope] Help writing test where bobobase_modification_time changes
Thanks for the tips Chris and Dieter, I actually solved it in a very simple way: from OFS.Image import File from time import time class MockFile(File): This file works the same as a normal File expect that in manage_edit() the internal modification time is set immediately. Normally Zope objects get their internal modification set when the transaction manager commits. def manage_edit(self, title, content_type, precondition='', filedata=None, REQUEST=None): # here's the mock hack, we set the _p_mtime NOW instead of letting # the transaction manager do it at the end. self._p_mtime = time() return File.manage_edit(self, title, content_type, precondition=precondition, filedata=filedata, REQUEST=REQUEST) This worked beautifully in the integration test.

Not easy. bobobase_modification_time() is in fact a DateTime representation of _p_serial. And _p_serial is the transaction id (also a timestamp) that has committed the object state belonging to this object incarnation. Unfortunately, you must not commit a transaction in a test suite (as this may cause interference with other tests). There is a small chance that a savepoint changed _p_serial -- but the chance is only small... You might be able to write _p_serial yourself and thereby trick bobobase_modification_time(). -- 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 )
[Zope] Help writing test where bobobase_modification_time changes
I'll try to explain as briefly as possible.
I've got a working cache pattern that keeps a cached version of a Zope
file's content and only when it changes (by
bobobase_modification_time) the cache is invalidated and recreated.
Here's the gist of my test
class Test(ZopeTestCase.FunctionalTestCase):
def test_recreateCache(self):
bla
self.folder.manage_addFile('foo.js','FOO data')
url = self.folder.mytool.cacheFile('foo.js') # pseudo code this time
path = urlparse(url)[2]
response = self.publish(path)
self.assert... tests on response...
_file = getattr(self.folder, 'foo.js')
_file.manage_edit(_file.title, _file.content_type,
filedata='new data')
newurl = self.folder.mytool.cacheFile('foo.js')
assert newurl != url, url hasn't changed :(
The reason it fails on the last line is that the time difference
between the first time and the second time is nil. Adding a
time.sleep(1) won't change anything because the
bobobase_modification_time() doesn't change.
How can I solve this? Make one big transaction two without having to
use transaction.get().commit() which I don't think I can use in unit
tests as per Dieter's advice.
Grateful for help.
Peter

Re: [Zope] help with customizing error messages, Zope 2.9
Dennis Allison wrote at 2007-9-20 09:37 -0700: ... standard_error_message should be acquired. It should be possible for there to be multiple copies with the particular one to be used selected by acquisition. This does not appear to be the case for some errors in my configuration, but I am not sure why. You are right -- and I can explain why. There appears to be nothing in the Zope 2.9 zope.conf file that has to do with catching error messages. Is there some configuration that is missing to enable full custom error messages. Looking at the code: ZPublisher/HTTPResponse.py seems to have a complete set of error responses hard-wired with outputs that mimic those of the default standard_error_message. OFS/SimpleItem.py includes a method called raise_standardErrorMessage which first acquires and then publishes the standard_error_message. Zope2/App/startup.py has a method, zpublisher_exception_hook which uses raise_standardErrorMessage and is referenced in ZPublisher/Publish.py where it is used to set error_hook, but error_hook does not appear to be used. It would be helpful to me if someone who understands how this particular code works could provide some hints as to what's needed to fully customize the error message responses. We start with ZPublisher. It is this component that catches the exception and activate error handling. ZPublisher was designed as a general publication component -- to be used not only for Zope. Therefore, it has neither error handling nor transaction handling nor a few other things hard coded. Instead, it gets a module name and determines the relevant pieces by a call to ZPublisher.Publish.get_module_info(module_name). When ZPublisher is used for Zope, then module_name is Zope2. Zope2 defines Zope2.zpublisher_exception_hook as its exception hook (which does the error handling). The true zpublisher_exception_hook is defined (as you found out) in Zope2.App.startup and copied to Zope2 by the _startup call. When ZPublisher catches an exception, it calls the error hook with parents[0] (the last or second to last object traversed to), the request and the error information. zpublisher_exception_hook then looks in the acquisition context of parents[0] for 'raise_standardErrorMessage' and 'standard_error_message'. If either of them is not found, the exception is raised -- and handled by the response object in a standard (minimal) way. Otherwise, 'raise_standardErrorMessage(standard_error_message, ...)' is called. The problem which sometimes causes surprises with respect to the used 'standard_error_message' lies in parents[0]: When the exception happens during traversal, then parents[0] is not the object you may expect -- but lies above the expected object. The problem is especially bad when the exception is raised by request.processInputs. In this case, the traversal did not even start and parents[0] is the root object. Consequently, for these exceptions, you will always get the standard_error_message from your root folder -- even when the request was targeted to some object deep inside your site. processInputs may raise exceptions when you use e.g. ZPublisher type conversions, e.g. :int or :float and the provided value cannot be converted. If you do not like this, you should not use ZPublisher type conversions. -- 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 )

the day but not hours, minutes and seconds). But the arithmetic
accepts float and that necessitates some surprises with
time discontinuities (such as daytime saving switches).
Can anyone help me figure out why the resulting date is coming up 1 hour
short of the expected 2005/11/01 ?

Subject: [Zope] Help with DateTime.earliestTime()
I've been having a site problem that I've tracked down to DateTime.
Simply
enough, the code snippets below both try to add 31 days to the first day
in
October. I'm expecting this to result in the first day of November.
Good Example:
from DateTime import DateTime
start=DateTime('2005/10/01 01:00:00 GMT-5')
print start
2005/10/01 01:00:00 GMT-5
earlyStart=start.earliestTime()
print earlyStart
2005/10/01
print earlyStart+31
2005/11/01
Bad Example: (Here's the problem)
from DateTime import DateTime
start=DateTime('2005/10/01 01:00:00 US/Central')
print start
2005/10/01 01:00:00 US/Central
earlyStart=start.earliestTime()
print earlyStart
2005/10/01
print earlyStart+31
2005/10/31 23:00:00 US/Central
I've confirmed this occurs with several of the US/ timezones (US/Pacific,
US/Alaska, etc)
Can anyone help me figure out why the resulting date is coming up 1 hour
short of the expected 2005/11/01 ?
I don't know what your problem is, but here are some code snippets I used to
get around a timezone problem I was having:
# def custom timezone class
class LocalTimezone(datetime.tzinfo):
def utcoffset(self, dt):
STDOFFSET = datetime.timedelta(seconds = -_time.timezone)
ZERO = datetime.timedelta(0)
if _time.daylight:
DSTOFFSET = datetime.timedelta(seconds
= -_time.altzone)
else:
DSTOFFSET = STDOFFSET
if self._isdst(dt):
return DSTOFFSET
else:
return STDOFFSET
def dst(self, dt):
STDOFFSET = datetime.timedelta(seconds = -_time.timezone)
ZERO = datetime.timedelta(0)
if _time.daylight:
DSTOFFSET = datetime.timedelta(seconds
= -_time.altzone)
else:
DSTOFFSET = STDOFFSET
if self._isdst(dt):
DSTDIFF = DSTOFFSET - STDOFFSET
return DSTDIFF
else:
return ZERO
def tzname(self, dt):
return _time.tzname[self._isdst(dt)]
def _isdst(self, dt):
tt = (dt.year, dt.month, dt.day,
dt.hour, dt.minute, dt.second,
dt.weekday(), 0, -1)
stamp = _time.mktime(tt)
tt = _time.localtime(stamp)
return tt.tm_isdst 0
# usage code...
Local = LocalTimezone()
chkDate = datetime.datetime.now(Local)
now = datetime.datetime.now(Local)
# see if we have to apply a local timezone offset
if tzo:
# get the number of hours less than UTC (GMT)
localTZO = int(chkDate.strftime('%z')[0:-2])
# make sure we have the target tzo as an integer
targetTZO = int(tzo)
diffTZO = 0
if targetTZO localTZO:
diffTZO = -(-targetTZO + localTZO)
elif targetTZO localTZO:
diffTZO = (-localTZO + targetTZO)
if diffTZO:
# we have to adjust our dates to account for the
time zone difference
chkDate = chkDate +
datetime.timedelta(hours=diffTZO)
now = now + datetime.timedelta(hours=diffTZO)
# create a time delta object (a date/time object that is a duration)
for 6 months
maxDate = datetime.timedelta(weeks=24)
# check for events within a 6 month window
while chkDate now + maxDate:
This code was just ripped from an application, but may provide you with some
ideas for a work-around.
Good luck!

[Zope] HELP! Will PAY YOU to Fix This Problem!
Hi; I just built out a new server according to a formulary I´ve worked before without any problems. Now, however, I have a bug in ALL of my Zope sites that throws a strange attribute error for various attributes that have always worked in the past (see thread AttributeError: Can´t Pin It Down!). I built everything from *.zexp files when my sites were working fine on my old server. I can send you the exact formulary I used to build the server (on FBSD). I have lost a couple of weeks over this silly problem that no one on the list has been able to address. HELP! Write me off list. Give me your hourly rate.

[Zope] help with detecting mime_type
Dears, In my external method I can get mime_type = file.headers.headers[1].split()[1] and then my code proceed based on which mime type was identified for the file uploaded. What happens now is that a user uploading a tgz file from a Windows platform and then my code did not identify it as a application/x-gzip-compressed or similar (it gets application/octet-stream). As far as I understood from this case, such mime type info is passed by user's system (where Windows usually is not aware of tar.gz, tgz etc format) rather than being set by zope server. So since I was not aware of that, my question is: does anyone know a better and reliable way of identifying a file mime type (or a file format) independent from which platform/browser it is submitted? I realise I can use a conditional for checking extension file name in addition to mime type detection. But I would go for that only if I cannot find anything fairer. Many thanks in advance.

I'm having a problem which must have been solved many times before- trying to make a product that ships with a skin. I'm new to Zope development, been stumbling for a couple months with it. Ideally, the end user will unpack my product Q into a Products directory. They will be able to add a Q object to an existing CMF site, or create a QSite at their Zope2 root. If they create a QSite, my product should give it a QSkin during instantiation. I'm developing the QSkin (and the entire Q product) on the filesystem. Background: The product includes a subclass of CMFSite called a QSite. If the user creates a QSite, I'd like it to include a QSkin which the user can select from the portal_skins tool. The product is running on Zope 2.9.4, Five 1.4, CMF 2.0. It needs to work on Windows and Linux. (Would like to use Zope 2.10, Five 1.5 when someone compiles the win32 installer, so I don't have to worry about five:traversable directives! Already posted a request for that.) Customer requires that the product have no Plone dependencies. Product will require workflow, so it can have a CMF dependency. Could possibly implement on Zope 3, though I could not figure out basic workflow management on that platform, and would rather not re-implement something available on Zope2. Hurdles I've had so far in creating a skin: Using Five- seems to be the way to go. Started by trying browser:page browser:defaultView with QSite/IQSite- really didn't know what I was doing, and a helpful sould pointed out, that is what skins are for. Tried using zcml skin directive, broswer:layer, and browser:defaultSkin. I can create a skin in zcml, and adding /++skin++QSkin to the end of any URL causes the page to load. However it does not look like a QSkin- apparently acquisition finds items in portal_skins before it finds resources added by five. So if I use zcml to add a Logo.gif, it won't override a Logo.gif already on the CMF site, to see it I have to also add /++resource++Logo.gif I cannot use defaultSkin with CMF, because CMF already declares a defaultSkin. Its better if the user picks the skin from the portal_skins management interface, but skins and layers declared in zcml don't show up there. As for the old/tried-and-true way, can't use the ExampleFileSystemSkin or MinimalPloneSkin as a starting point, perhaps they use parts of Plone: cannot import name ContentFactoryMetadata. http://plonebook.packtpub.com/chapter6_preview.htm looks promising. Hurdles I've had so far installing the skin: Tried using container events (subscriber zcml) to call a hook when a QSite is created, presuming that I'd work skin magic on the new site object from within the event handler. Alas that is not the intended purpose of subscriber and while it may work in the future, events don't fire on CMFSite objects yet. Am I supposed to create a manage_afterAdd method in my QSite object, even though it's depreciated? Hmm, just tried creating that as a method of QSite and it doesn't get called either- what's the right way? Thanks for reading my rambling. ___ 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] Help! Zope Crashed! Production Server!
Since you're running it with runzope (i.e. in foregreound mode): 1) Can you confirm Zope provided the message Zope Ready to handle requests 2) What is the top command showing? Is python/zope process using CPU, or is it simple unresponsive? 3) Can you check if there are different processes when you start and when you do your first request? With some C extensions of python, you can end with hanging python processes (at least on Linux; don't know on FreeBSD). 4) Is the zope process able to write to Z2.log, event.log and (if used) trace.log? Hope this can help.

[Zope] Help! Zope Crashed! Production Server!
Hi;I'll afford a server to experiment on before year's end, but that doesn't help me today. I was trying to get Python 2.3.5 to work with LDAP on FreeBSD. I built py-ldap2 from ports and directed it to install Python 2.3.5 (because I'm using Zope 2.7.8 because my software won't migrate yet). It built out okay. The person who ran this box previously didn't understand FreeBSD's port system, so he built Python in a different place. I moved all of that for safety's sake (at least, I thought I did), and then ended up moving it all back because I couldn't fire up Zope (I have 2 instances). Then I was able to fire up Zope *and* import LDAP (the latter indicating something from my new installation stuck). When I ps wax I see Zope is working. However, when I surf to sites, or even the IP address, it just hangs! I cleared out log/event.log and touched it and fired up in runzope mode, but there was nothing strange in the event.log! And I've been over that log many times lately, so I would recognize something different. I presume ZServer is hung. How do I trouble-shoot this?TIA,Javier2 Do you Yahoo!? Get on board.

[Zope] Help! I Screwed Up a Source File
Hi;
I inherited this box so I don't know exactly how this file got built;
however, it's python 2.3.5 and zope 2.7.8. I apparently screwed up this

which incorrectly reads like this:
#!/bin/sh
# ZEO instance control script
# The following two lines are for chkconfig. On Red Hat Linux (and
# some other systems), you can copy or symlink this script into
# /etc/rc.d/init.d/ and then use chkconfig(8) to automatically start
# ZEO at boot time.
# chkconfig: 345 90 10
# description: start a ZEO server

I need to control the view method, but i don't know if this idea is the right one or there are better solutions. Any hints? Thanks, Bruno Bruno, Maybe you can better explain your question. Im not at all sure the following will help: Seems like you can check a users credit at login, store the credit score in SESSION and use that for branching logic. You could also update the creditScore as it changes. Then you can develope your pages with stuff like this: (syntax not checked) in TAL a hRef=somewhere tal:condition=python: request.SESSION['hasCredit'];This link only shows up if session's 'hasCredit' is true./a In DTML dtml-if SESSION['hasCredit'] a hRef=somewhere ... dtml-else hRef=somewhereelse In Python: (and TAL macros) if context.REQUEST.SESSION['hasCredit']: return container.Images.macros['allImages'] else return container.Images.macros['someImages'] David ___ 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 )

[Zope] Help with Zope Python result object please!
hello, I have a python code that recieves two result objects from two different ZSQL methods. I need to join them (sort of like UNION). I can't do result1+result2, otherwise it raises an exception that the + operator isn't supported. When I try to do this (read below, I explained what i've done if you are lazy to read the code) result1 = context.zsqlmethod1() result2 = context.zsqlmethod2() if (len(result1) == 0): return result2 row1 = 0 row2 = len(result1) + 1 col = 0 for r in result2: col = 0 if (context.duplicateExists(result1, result2[row1][0]) == -1): result1[row2][col] = result2[row][col] col = col + 1 row1 = row1 + 1 row2 = row2 + 1 return result1 Basically, it loops through the rows and columns of result2 and adds them to the end of th e result 1. However it for some reason raises "index out of range" and says that assigning result1[0][0]=result2[0][0] (if there is an element in both of them) is illegal because: Error Value: object does not support item or slice assignment I realize that in most programming languages you can't add them to result1 without resizing it first, but I can't find much documentaiton on member functions of the result object, so I can't resize it. I am completely stuck, I've tried everything, spent so much time on it, can anyone please help save my sanity :P Thanks in advance guys! I really appreciate it. Yahoo!
