This doesn't work. Nothing gets printed.

In the News folder is a DTML method called news999. Should it be a
DTML document instead for this to work?

I tried the three methods you gave me. objectValues, "objectValues()"
and "objectValues('[File]')" and even "objectValues('[news999]')" but
empty everytime.

Hi everyone,
   
Simple newbie question... :)
   
I've made a directory called News into which I will
 put files named
newsXXX. X being a number from 999 to 001.
   
What I want to do is to tell zope to put each file
 into a document.
Now, here is what I figured out.
   
dtml-with News
  dtml-in ??? --- that's where I'm stuck. I don't
 know how to
iterate through a directory ... I want ALL the
 newsXXX displayed.
  /dtml-in
/dtml-with
   
How do I do that?
   
TIA

Re: [Zope] how to get the created table names

2000-11-24 Thread Jose Soares


There isn't a SQL standard command to show the tables in the database.
Thus evry database has a different command to do such job.
For example:

DBMaker:
  to show TABLES:  select  *  from SYSTABLE
  to show COLUMNS: SELECT  COLUMN_NAME,TYPE_NAME,PRECISION  FROM
SYSCOLUMN  WHERE  TABLE_NAME='table_name'
MySQL:
  to show TABLES:  SHOW TABLES
  to show COLUMNS: DESC table_name
PostreSQL:
  to show TABLES:  select tablename from pg_tables where tablename not
like 'pg_%'
  to show COLUMNS: SELECT a.attname, t.typname, CASE WHEN a.attlen  0
THEN attlen ELSE a.atttypmod END as length FROM pg_class c, pg_attribute
a, pg_type t WHERE c.relname = 'table_name' AND a.attnum  0 AND
a.attrelid = c.oid AND a.atttypid = t.oid


I wrote a couple of ZSQL Methods to emulate a generic ISQL
to query a database using the SQL language
which shows the names of every table in the database
and every column name, type and length of every table.
If you want I can send you it.

[Zope] seeking zope success stories in higher education

2000-11-24 Thread Jerome Alet


Hi,

We are planning to choose a platform to build a portal for distance
learning, with which we want to Build and Serve online multimedia courses,
online exams, calendars, keep track of students work and results, forums,
etc... 

I've got a list of criterias the platform must fill to be chosen, and at
first glance Zope fills at least 90% of them, and probably more if I look
more closely at the Zope products already available.

This is a big project, and some people
have already done some work using WebCT. I've read in the zope-edu wicki
the comment on WebCT, I already know that many people (at least 35) are
interested byt his subject because they are referenced as contributors in
this wicki, so I naively conclude I'm right in thinking that Zope is the
good choice for us.

So I have to write a document explaining the pros (and cons) of choosing
Zope, and I want some references of Zope uses in higher education if
possible.

Please could someone send me any testimonial on the (successful or not,
and why) use of Zope in higher education, the products which might help us
(we will at least need SquishDot, the LDAP adapter, the Oracle adapter,
the KnowledgeBase product, etc...). I'm also interested in testimonials
about the use of WebCT or similar products.

Thank you very much.

PS: As always this is urgent :-(

RE: [Zope] Newbie Question Fixed but continuing.


Thanks Philipp and Jim,

It worked! But... (there's always a but! :) I thought I was clever
when I thought about naming my news files news999, news998 etc,
thinking it would parse the directory and print the news sorted by
their names. So news998 would be printed before news999 etc. It
doesn't.

deleted questions because it's fixed :) /deleted

Now this too is fixed. I just discovered the "sort=" thingie.

One thing would sure be helpful, a Guide explaining all the subtags in
a tag. Like what can be used in a dtml-var or dtml-in and params
for each subtag. Because as someone mentioned, searching on zope is a
real hassle. It takes a long time, and the search is ORed. So lots of
unrelated docs are counted as a hit.

Thanks a lot to all the helpers.

Dany

  To be quite blunt, this has now been _decided_ as I understand it. So
  it's pointless to keep arguing and suggesting new and different names.
  We now _have_ a president and it's name is 'Python Script' ;-)
 
 With all due respect to everyone, this should not be considered a closed
 issue.

It is.  This is the kind of thing where it is impossible to make 100% of
the participants happy, we regret that not everyone is going to go for
it, but we *must* move forward.  This issue is holding up Python
Scripts, which is holding up the book, which is intimately tied to Zope
2.3, all of which is intimiately tied to my paycheck.  My paycheck
doesn't really have anything to do with it but I just thought I'd
mention it. ;)

  My understanding is that there would be a vote for a name.

We could not afford any further delay, and the last poll was a
disaster.  The author of Python Scripts (the majority of which were
written before he worked at DC) rightly asserted his position and picked
a name.  I'm sure it wasn't easy for him, and there was lots of internal
conflict; many in the company not liking 'Script' for many of the same
reasons you do.

 Skipping that in the name of getting things moving after it was offered by
 Digital Creations seems to go against the open source nature of the
 product. 

That is tying a strong semantic relation between "open source" and
"democratic".  In my mind, the open source nature is that anyone can
examine, author and contribute code to a project for peer review and
inclusion.  Evan did just that, he wrote most of what used to be called
Python Methods before he worked at DC and contributed it freely under
the open source mantra.  I don't think voting has much to do with open
source, it has worked for us (with the documentation poll) and failed
for us (with what used to be called Python Methods) but we'll probably
try it again.

 Not to mention that the name chosen does nothing to distinguish
 it from an everyday Python "script" outside of Zope, which is what sparked
 the name change to begin with.  "It's not really a Python method, so let's
 change the name."  Well, it's not just a "Python Script" either.  It's
 Zopified.

Just to clarify, in the Python language, there is no such thing as a
"script".  What you are thinking of as a "script" is really some hunk of
data (probably a file) containing python code that contains either some
platform specific hook to invoke the interpreter, or that you pass to
the interpreter on the platform specific "command line".  Neither of
these things have anything to do with the language called Python.  Once
inside the interpreter, you are officially working with "modules". 
"Modules" and "methods" are real, defined, un-ambiguous Python objects
defined in the Language Reference
(http://www.python.org/doc/current/ref/ref.html).  Obviously, naming a
Zope object "module" or "method" would be a bad idea, and therein lies
the problem.  

"Script" is just un-bound, non-python specific, vague lingo that
everybody uses to describe a chunk of code in just about any language,
on any platform.  In this case, the platform is Zope, the chunk of code
is written in Python, and the "command line" is your web browser.

I can sympathize with your feelings, but one of the reasons I don't like
"Method" is because it's is OO specific; it is a very technical term. 
"ZMethod" is no better, even if it doesn't have the problem of clashing
names with a python object (and barely not clashing at that!).  We want
to make using Zope easier.  For the target audience we want to approach,
if 1000 people pull down the add list and see "Python ZMethod" many more
of them are going to scratch their heads about what the hell a ZMethod
is than if they see "Python Script".  "Oh, a python script?  Cool!  I've
written some CGI scripts!  Now I can go and read chapter six of the book
'Scripting Zope' and find out how to 'script the web'!"

There is no such thing as a "script" in the Python language (see the
index of the "language reference" on the python site, you will find
"method" and "module" but not "script").  "Script" is just a word that
is informally and commonly used to refer to a chunk of code written in
some language on some platform that is invoked by some action, possibly
from a "command line" or by double clicking on an icon.  In the case of
a Zope Python Script, the code is written in python, the platform is
Zope, and the "command line" is your web browser.

2000-11-24 Thread Federico Di Gregorio


Dear PoPy and ZPoPyDA users,

 last days, a lots of stuff happened here at MIXAD LIVE. the most
important to you is that source code for the programs is not in our cvs server
anymore and the home page was moved to the official Zope site[1]. To make it
short, thierry and eric decided to not work for MIXAD LIVE anymore.

   so, what will change for you PoPy users? hopefully nothing... we'll
continue to submit patches (we are using the product a lot) and to host the
mailing list (unless they wants to move it away.) i will personally keep on
packaging PoPy and ZPoPyDA for the Debian distribution. we also want to
transfer to thierry the copyright of all the work done by us on the programs,
to give him total freedom. i think PoPy and ZPoPyDA will grow better and
better in the future.

what can i say more? maybe "good luck" to them and "keep on hacking"...

RE: [Zope] Newbie Question Fixed but continuing.


Thanks! That's exactly what I was looking for.

I know that the DTML reference is there on Zope.org but it's a hassle
and well, I'll keep my other opinions for myself.

Anyway. Here's an idea. Shouldn't there be a list FAQ? If there is one
it should be sent when subscribing. Or it could be requested. I'm
pretty sure most of the questions I sent have already been sent 
answered more than once already and I know some that most other FAQs
use one. So, why not zope general list? It *is* possible, though
unlikely, that there is a list FAQ mentionned in the "Welcome to Zope
mailing list" email but if there is, my apologies.

Thanks.

is:

 /* 20.11.2000 by Perry */
 case PG_NUMERIC:

refuses to put the correct title. It doesn't even put the header's

Re: [Zope] Special behavior or bug?


Make sure that the standard_html_header is a DTML Method and not a DTML
Document.  Make sure that the calling document is DTML Document and not a
DTML Method and it should work.  That way the header acquires the title of
the calling document.  If the calling document is a DTML Method, it
acquires it's title from somewhere else according to the Zope rules of
acquisition (as opposed to the Ferengi rules of acquisition ;).

Re: [Zope] how to get the created table names

2000-11-24 Thread Steve Spicklemire



Hmm.. I think there is a method of a ZSQL result object called 'names'.. 

Here is a snippet from some working code:

dtml-let specificTypes="getTypes(ttid=type, name='', tttype='')"
  theNames="specificTypes.names()"

where 'getTypes' is a ZSQL Method and theNames is the list of column names returned
from the query...

 to:

 dtml-call "UpdateHours(myval=_['myval'], mykey=_['mykey'],
 sequence_item=_['sequence-item'])"

 and change the name of the parameter in your ZSQL method from
 sequence-item to sequence_item and change the dtml-var tag in the method
 to dtml-var sequence_item.

SQL
  in the DTML (ie displayed it within the page) and I've copied and pasted
  that SQL directly into a ZSQL Method and ran it on my database and that
  works fine.  However it seems to do absolutly nothing when I actually

I'm

   Try dtml-var "0/0" just before the call to UpdateHours.

RE: [Zope] Special behavior or bug?


Chris, I can't change all the other DTML Methods to DTML Docs... I
would have to have only 1 DTML Method which is unthinkable.

Now, I'm sure there's a way to force what I want to do. Either with a
REQUEST.set('[calling_document.Title]') or something real :)

Is there such a function? (I'm sorry, I'm still confused on how to
call things in Zope.)

As for the Ferengi rules of acquisition, at least, I'm pretty sure I'd
get some profits :) haha But, unfortunately, my ears are not as
erogenous as the Ferengies.  :)

Re: [Zope] DC request re: Objection to Python Script Name

2000-11-24 Thread Hamish Lawson


When I 'jumped in' (nod to Chris Withers :-)) with my promotion of
ZMethod, I'd missed Evan's announcement that he'd decided on Python
Script - I thought it was just another suggestion and we were still in
the middle of campaigning for the upcoming second poll! I'm actually
not that averse to Script; it was ZMethod's OO associations that I
liked - but if Michel thinks that such an association is actually not
appropriate in this situation, then I'll bow to his greater Zope
understanding. I agree with him that the new name needs to make it into
the book, and Script is a reasonable choice. Is it intended to rename
DTML Method, ZSQL Method, etc to be DTML Script, SQL Script, etc? For
the sake of consistency I'm hoping so, and I think it's important that
these revisions also make it into the book.

Onwards!

Re: [Zope] Zope with Microsoft Access

2000-11-24 Thread Rik Hoekstra



 Hi, this is my first posting to the list, and about my 4th day working
with
 Zope.  I have a bit of a problem.  All my code so far is working well.
Just
 the following section is defying my attempts to make it run.  What it does
 is to update a field in the database (to allow employees to quickly update
 their hours in the hours tracking thing I'm creating)  it's complex since
 all the employees hours will be listed on one page and will be instantly
 updatable (with a select box that allows the choice of +/- (name is
 modifydtml-var hoursID and value is either + hours already input or -
 hours already input) and a text field for entering hours to add or
 subtract (name is mod_hoursdtml-var hoursID)).

 The code (in the DTML document) is:

 dtml-in "REQUEST.form.items()"
 dtml-if "_.string.find(_['sequence-key'], 'mod_hours')"
 dtml-else
 dtml-let mykey=sequence-key myval=sequence-item
 dtml-in "REQUEST.form.items()"
 dtml-if "_.string.find(_['sequence-key'], 'modify')"
 dtml-else
 dtml-if "_['sequence-key'][6:9] == mykey[9:12]"
 dtml-if myval
 dtml-call UpdateHours(REQUEST)
 /dtml-if
 /dtml-if

 /dtml-if
 /dtml-in

 /dtml-let
 /dtml-if
 /dtml-in

 and the SQL method UpdateHours is:

 update emp_hours set hours =
 dtml-var expr="_['sequence-item']"
 dtml-var expr="_['myval']"
 where
 hoursID = dtml-var expr="_['mykey'][9:12]";

 with arguments: sequence-item, myval, mykey

 I've tried everything I can think of but it not only refuses to do
anything,
 it also refuses to raise an error.

 If anyone can help out I'd be very grateful.


This seems to be more of a DTML problem than an Access problem. It is hard
to follow anyway...
A few questions: have you tried using something like changing the form names
to using the name.item:records syntax. something like

input type="checkbox" name="modify.dtml-var hoursID:records" value="+"
input type="checkbox" name="modify.dtml-var hoursID:records" value="-"
input type="hidden" name="modify.inputhrs:records" value="hours already
input"
and a text field for entering hours to add or
input type= "text"  name="modify.mod_hours:records" value="dtml-var

this will give your dtml method a dictionary like structure called modify
you can loop over.

Starting from there will save you a whole lot of hacking. Also I'm not at
all sure that you can use the [sequenct-key] as arguments for your SQL
Method.

[Zope] ZCatalog and Zsearch Interface.

2000-11-24 Thread Srinath Mantripragada


Hi,


I need to know how does the search works.


The index of Catalog is made based in a pythonMethod that returns an
concatenated text with the contents of a lot of fields

I made an external method in python that do the search and sort the entire
result.
It´s an priorized sort, that i need to priorize the keywords, so the results
that have the searched text in the keywords list will be showed first.

I made the sort by dividing the resuilts in two secondaries lists, one that
contains the results with searched text in the keywords and the another that
does not.
finaly I return the two lists concatenated.


I need to know if there is a better way to do the priorized search in many
fields and if the solution that I made will "destroy"  the server´s memory
and/or cpu.

If possible, i want to know how the ZsearchInterface works  internally..


Thanks..

Srinath M.

Re: [Zope] Zope with Microsoft Access

I actually have this up and running now (as of about 5 minutes ago).  It's a
hack but it works great so I'm not going to mess with it.

Thanks a lot to everyone who gave me pointers, most especially Chris Gray
whose solution fixed it in the end.

Now I need a way of implementing Apache style authentication.  Is there an
easy way to do this?

Subject: Re: [Zope] Zope with Microsoft Access



  Hi, this is my first posting to the list, and about my 4th day working
 with
  Zope.  I have a bit of a problem.  All my code so far is working well.
 Just
  the following section is defying my attempts to make it run.  What it
does
  is to update a field in the database (to allow employees to quickly
update
  their hours in the hours tracking thing I'm creating)  it's complex
since
  all the employees hours will be listed on one page and will be instantly
  updatable (with a select box that allows the choice of +/- (name is
  modifydtml-var hoursID and value is either + hours already input
or -
  hours already input) and a text field for entering hours to add or
  subtract (name is mod_hoursdtml-var hoursID)).
 
  The code (in the DTML document) is:
 
  dtml-in "REQUEST.form.items()"
  dtml-if "_.string.find(_['sequence-key'], 'mod_hours')"
  dtml-else
  dtml-let mykey=sequence-key myval=sequence-item
  dtml-in "REQUEST.form.items()"
  dtml-if "_.string.find(_['sequence-key'], 'modify')"
  dtml-else
  dtml-if "_['sequence-key'][6:9] == mykey[9:12]"
  dtml-if myval
  dtml-call UpdateHours(REQUEST)
  /dtml-if
  /dtml-if
 
  /dtml-if
  /dtml-in
 
  /dtml-let
  /dtml-if
  /dtml-in
 
  and the SQL method UpdateHours is:
 
  update emp_hours set hours =
  dtml-var expr="_['sequence-item']"
  dtml-var expr="_['myval']"
  where
  hoursID = dtml-var expr="_['mykey'][9:12]";
 
  with arguments: sequence-item, myval, mykey
 
  I've tried everything I can think of but it not only refuses to do
 anything,
  it also refuses to raise an error.
 
  If anyone can help out I'd be very grateful.
 

 This seems to be more of a DTML problem than an Access problem. It is hard
 to follow anyway...
 A few questions: have you tried using something like changing the form
names
 to using the name.item:records syntax. something like

 input type="checkbox" name="modify.dtml-var hoursID:records" value="+"
 input type="checkbox" name="modify.dtml-var hoursID:records" value="-"
 input type="hidden" name="modify.inputhrs:records" value="hours already
 input"
 and a text field for entering hours to add or
 input type= "text"  name="modify.mod_hours:records" value="dtml-var
 hoursID"

 this will give your dtml method a dictionary like structure called modify
 you can loop over.

 Starting from there will save you a whole lot of hacking. Also I'm not at
 all sure that you can use the [sequenct-key] as arguments for your SQL

[Zope] view DTML source

2000-11-24 Thread Anders Eriksson


Hello zopistas,

On the zope.org there is a 'method' called view_source, which lets you
see the DTML source of a page. I 'borrowed' this code, by using
view_source on itself and got this:

!--#var standard_html_header--
pre
!--#var "document_src(REQUEST,RESPONSE)" html_quote--
/pre
!--#call "RESPONSE.setHeader('content-type','text/html')"--
!--#var standard_html_footer--

I then created a DMTL-document called 'view_source' with this content.
But when I run, using http://swescout.myip.org/index_html/view_source
it I get this traceback:

Re: [Zope] how to get the created table names



There is no tag that shows tables and there will be not be such tag.

What you might want to look into ; ZnolkWizard.. This is a handy module
which queries for tables in your database and build create/edit/delete
forms. There is also a handy way to specify key-related data. This gets
you half way to build UIs when you have many tables.

Good luck.

Jose Soares wrote:
 
 There isn't a SQL standard command to show the tables in the database.
 Thus evry database has a different command to do such job.
 For example:
 
 DBMaker:
   to show TABLES:  select  *  from SYSTABLE
   to show COLUMNS: SELECT  COLUMN_NAME,TYPE_NAME,PRECISION  FROM
 SYSCOLUMN  WHERE  TABLE_NAME='table_name'
 MySQL:
   to show TABLES:  SHOW TABLES
   to show COLUMNS: DESC table_name
 PostreSQL:
   to show TABLES:  select tablename from pg_tables where tablename not
 like 'pg_%'
   to show COLUMNS: SELECT a.attname, t.typname, CASE WHEN a.attlen  0
 THEN attlen ELSE a.atttypmod END as length FROM pg_class c, pg_attribute
 a, pg_type t WHERE c.relname = 'table_name' AND a.attnum  0 AND
 a.attrelid = c.oid AND a.atttypid = t.oid
 
 I wrote a couple of ZSQL Methods to emulate a generic ISQL
 to query a database using the SQL language
 which shows the names of every table in the database
 and every column name, type and length of every table.
 If you want I can send you it.

/docs/ActivePython instead of / docs/ ActivePython. That means I can cut and

 There is no such thing as a "script" in the Python language (see the

 "method" and "module" but not "script").  "Script" is just a word that
 is informally and commonly used to refer to a chunk of code written in
 some language on some platform that is invoked by some action, possibly
 from a "command line" or by double clicking on an icon.  In the case of
 a Zope Python Script, the code is written in python, the platform is
 Zope, and the "command line" is your web browser.
 

Connotatively, scripting rings the same meaning as ASP scripting,
ColdFusion scripting,
PHP scripting, JSP scripting... How is Python script different from
them? 

But Python script isn't "SCRIPTING" in that sense of the word.

Hello all,

I have a Squishdot site at http://www.linuxmednews.com that I've
successfully been able to make a page that has a one line link of all
the articles that have appeared on the site. Unfortunately, the number
has grown to a few hundred and I need to make it display n lines at a
time as well as count them so I can keep track. I am trying to use the
following code to display them with a count, but I've tried just about
everything and spent hours on this 'simple' task, but can't get it to
work. This is as close as I could get only it numbers the articles that
appeared on a particular day, then jumps to the next day that articles
where posted. i.e. not a smooth 1 to n count.  You can see what it does
at: http://www.linuxmednews.com/linuxmednews/display_old_articles Could

[Zope] Python and EJB (J2EE)

2000-11-24 Thread Hung Jung Lu

Python and EJB (J2EE)
=

Searching through comp.lang.python newsgroup archive
([EMAIL PROTECTED]) and the [EMAIL PROTECTED] mailing list, I have not been
able to find much about EJB (Enterprise Java Bean) and Python/Zope
comparisons. (J2EE is Java Two Enterprise Edition, basically another jargon
for any architecture based on EJBs.)

I believe this field deserves to be explored a little bit more. If Python is
going to be more used in the corporate environment, it has to be made
stronger. This message is kind of unorganized, but I would like to have
comments/feedback from other people.

The following message shows that I am not the only one interested:

ruben [EMAIL PROTECTED] 11/08/2000 in comp.lang.python:

Coming from a Java background and recently using Python for application
development, I have a question. Is there an equivalent to Enterprise
JavaBeans in Python? If so, please point me to some resources!!!

Similarly Joe Grace [EMAIL PROTECTED] has posted an explanation on J2EE in
the Zope mailing list:

http://zope.nipltd.com/public/lists/zope-archive.nsf/0dec1f578f18f116802568ab003585d2/86cffddc1a8a73b980256865006d44a2?OpenDocument

I am starting to look into Java EJB, and I must say that despite all the
hype, it is totally horrible. I can understand the goals of EJB, but I
wonder whether something simpler and cleaner might be better. EJBs,
especially entity beans, have largely failed and have disappointed many Java
developers, or so it seems from the comments I have received from other
people.

First off: what is an EJB? There are plenty of books out there, there are
plenty of websites out there, but you'll probably be hard-pressed to find
someone that has actually worked with EJBs. I've never liked the names "Java
Beans" and "Enterprise Java Beans". These are marketing names. We need some
more generic names. "Java Beans" are an attempt by Sun to implement
component programmming. That is, the idea is to have component classes on a
single machine (virtual machine in the case of Java) that can be shared/used
by different programs. In this sense, "Java Beans" are much like DLLs, Unix
shared libraries, Python modules, or Microsoft's COM, ActiveX stuff. "Java
Beans" are designed to be shared within one single machine. "Enterprise Java
Beans" are much more complex than "Java Beans", and they are aimed at
distributed computing: EJBs are designed as classes/components to be shared
by multiple machines. In this sense, they are more like CORBA, or
Microsoft's DCOM. Therefore:

(1) Java Beans --- local components, run on the same machine
(2) Enterprise Java Beans --- distributed components, distributed
computing, multiple machines, potentially located in different geographic
locations. These components often have instance pools running in multiple
threads, and often are transactional.

What about Python? Or Zope? Simple distributed computing is not too hard to
implement. CGIs in fact are a way of distributed computing. Python does have
DCOM (Mark Hammond) and CORBA. But I don't think DCOM/CORBA are the way to
go. In Python/Zope world, I guess Fredrik Lundh's XML-RPC is the closest
starting point for distributed computing, and eventually for something
similar to EJB container. (See http://www.zope.org/Members/Amos/XML-RPC for
XML-RPC in Zope and http://www.pythonware.com/products/xmlrpc/ for XML-RPC
in Python.) There is also (See SOAP
http://static.userland.com/xmlRpcCom/soap/SOAPv11.htm ), which is an
extended version of XML-RPC.

For more information on XML-RPC, visit http://www.xmlrpc.com/ .

Zope can be used as equivalent to EJB container. But Zope is a general
webserver with a lot of features that a simple server don't need.

EJBs are there because of a few good reasons:

(1) Multi-threaded, workload distribution, instance pooling
(2) Security
(3) Transactional
(4) Managed persistence (for "entity beans" in the EJB jargon)

These are all important requirements for the corporate world. Can Python do
all these things? The answer right now is no. There is nothing really
equivalent to EJB in the Python world.

Security: Python is great for rapid development. The
reflection/introspection power of Python is wonderful. I particularly like
the absence of the "private" keyword. In C++ and Java, corporate security is
implemented at the language level, which makes these language quite
annoying, in my opinion. That being said, corporates DO need security
mechanisms. If Python were to be used in corporate environment, there MUST
be a security interface layer. We don't want any employee to be able to peek
into the president's salary, for instance. That is, absolute data hiding at
a higher level is necessary. As Java/C++ have shown, data hiding at the
language level not only is an illusion, but ties up programmers hands too
much. So, it's best to leave the language itself free, and implement the
data

[Zope] Passing Variables to a Wizard

2000-11-24 Thread Nestor A. Diaz L.


HI,

Does anybody know how can i pass variables from a product to a Wizard.

I mean:

I am using the PTK to create my own product however PTK use the Wizard as
the default method to add a product, how can i pass variables to a wizard
form a python product ?

I can pass variables to the edit method using the following:

editForm=HTMLFile('dtml/edictoEdit', globals(),  typeList = type_list)

Where typeList is a global array.

But i don't know how can i do the same with a wizard.

Thanks

[Zope] BSD 4 installation

2000-11-24 Thread Lee Hunter


I'm trying to build Zope on a BSD server.

According to the install.txt I have to run two commands - "python w_pcgi.py"
and "./start".

I managed to get the first command to run (python w_pcgi.py) after editing
my Makefile.pre.in and do.py as per the FAQ.txt.

But when I when I run the second command (./start) I get the following error
message:

media2: {38} % ./start

Re: [Zope] Python and EJB (J2EE)

Good topic. I was hoping someone would come around to this. Perhaps,
there should be a thread of discussion on this.

I dont' know what is there to compare. EJB has been around awhile and
J2EE is yet another jargon to throw people off. Here is what we have
experienced; 1. Anything that needs to be done on J2EE takes twice as
long and of course, costs more. 2. Of "Java" programmers (there are
many, 2M strong as a Java wannabe proclaims), only handful of
programmers can really do anything. 3. Corporations are still very much
enamored with Sun and Java with an idea "Sun is big and we can't go
wrong with it. Zope and Python, I am clueless." 4. My close friend
specifies Java language and he won't have anything to do with Java
application. There is a theory that in Amercia, we make most of our
money with hypes as if it is a bad thing when things work.

Nevertherless, I think there needs to be a study of point-by-point
comparison between EJB and Zope. Don't look at it from Zope/Python POV
but from Java the Hut POV. Python folks don't really know what resuable
codes and libraries they all have and their developments have been
organic. I admit I don't know this for sure. I am being a devil's
advocate. Some hot developers throw some stuff and we marvel at them.

I think for Zope/Python to become enterprise, it needs to have quite a
few things and I like to know if its community is ready for the mundane.

Here are some topics;
1. Message queue
2. implementation of protocols such as SOAP, BXXP
3. better documentations for different levels of readership (decision
maker, developer, systems architect, etc)
4. promotions, workshops and training
5. learning to play golf and smoke cigar...

Re: [Zope] DC request re: Objection to Python Script Name

2000-11-24 Thread Ron Bickers


Quoting Hamish Lawson [EMAIL PROTECTED]:

 understanding. I agree with him that the new name 
needs to make it into
 the book, and Script is a reasonable choice. Is it 
intended to rename
 DTML Method, ZSQL Method, etc to be DTML Script, SQL 
Script, etc? For
 the sake of consistency I'm hoping so, and I think 
it's important that
 these revisions also make it into the book.

I agree that this consistency is important, and "before 
the book" is a good time to disrupt names.

Also, what about External Method?  External Script?  
Also, are these going to remain only available in the 
Python language?  If not, that name becomes an issue 
too.

I hope all this naming talk isn't too distracting for 
DC, but I (and clearly others) think it's important, 
esp. before the world sees it in print.

The Medusa monitor allows you to connect to a running Zope

With it, you can (in principle) analyse your Zope system.
However, this way of debugging is probably only for experts.

There is a document at zope.org (I forgot its name) that says
a bit about this "monitor": search for "monitor".

Try "import _pg" in an interactive Python interpreter.
I remember that in some cases I got a better error message

If it does not, then you may try "ldd _pgmodule.so"

It will tell you, when there are some missing.

That is very strange as "standard_html_header" does have

Thus, I can not tell you, why you see this behaviour.

However, you may use "document_src" directly in the
URL. I.e. you do not need a special DTML method 'view_source".

Try something like this:

This only affects "App.ImageFile" objects.

although special applications may use them too.
However, most images in Zope are "OFS.Image" objects that
do send "Last-Modified" headers.

In Zope 2.2.4 (to be released soon), the problem is fixed.
The "b1" version has fixed it, too, but a small bug slipped

  Wrap you results into a custom brain that either

about RPC (Remote Procedure Calls), but not enough
that you could use it directly.

I am sure, you will find the book draft via "zope.org",

in the Zope book and the list archives, for example.

Re: [Zope] Python and EJB (J2EE)

2000-11-24 Thread Ender

i've been playing around with servlets (tomcat, jserv, orionserver.com)
and generally been pretty happy with them. development cycle is a lot
slower than zope. i did some prelim work on hooking up jserv to zope but
gave up cause the performance generally sucked (jserv is still using
apj1.1 which doesn't have persistent connections) and figured there were
easier ways to get the two talking besides directly ala distributed
protocols or shared backend resource like a rdbms.

j2ee is more than just ejbs, its a whole slew of technologies like
(jdbc, jndi (directories), jms (messaging), jts (client transactions),
jaxl?(xml)...). one advantage of using java for a project thats going to
be talking several of these protocols is the fact that there is a
standard supported library for it as opposed to python's bazaar style of
development and support (not to mention documentation). integration of
this stuff in python generally requires evalutation on a per
protocol/library basis because in some cases the library just isn't
robust enough to handle the work (python's soap support comes to mind).

as for component technologies, i really feel this comes out more as a
programming paradigm in python rather than a forced technology.

as for distributed technologies, while xml-rpc is useful and simple its
not useful (IMO) for enterprise programming, its too basic. it requires
alot of custom app programming to transfer meaningful exceptions. some
protocols/libraries that i would like to see in python would be soap,
wddx (bindings for httpsoap), uddi. i've never used com/dcom so i've
nothing to say about them. python does have great corba support
(omniorb, fnorb) and some is working on integrating zope as a corba
system (hopefully they'll write up a howto/ release some code), and pyro
can cut it for simple distributed systems.

so what would you like to see in a python component container?

RE: [Zope] Special behavior or bug?


Sorry, but my understanding (which certainly may be wrong, since I don't
fully grasp the ins and outs of this yet) is that the namespace starts
with the client object to which the method is bound.  The attributes (like
title) of the method never get into the namespace.  This is part of the
design of DTML Methods; they can be bound to a variety of objects while
still giving full access to the client's namespace.  This is why the trick
of calling a DTML Document's title from an embedded DTML header Method
works.  The effect you want to achieve depends on this distinction between
DTML Methods and Documents.

Another way to say this is that the distinction between DTML Documents and
Methods allows a separation of content and logic.  Put your content
(including Titles that will be significant to your visitors) in Documents
and your logic in Methods.

Cheers,
Chris

   It traverses the ZODB guided by the components in your URL.
   It it arrives at the URL's end, it checks whether the
   reached object is callable (this is the case for all
   kinds of methods and documents). If it is, the object
   is called.
   If it is not, ZPublisher checks, whether the object
   has (or can acquire) a method "index_html"
   (this usually is the case). It then calls this method.
 
 In your case:
 
   ZPublisher will reach the result object (as the Zope book
   describes). Unless you have wrapped this object
   into a custom class (aka brain, see "Advanced" tab),
   this is a "Record" object.
   A "Record" object is not callable.
   "index_html" is looked for, found in a folder above and
   rendered.
 
   That's what you see.
 
 What can you do?
 
   Wrap you results into a custom brain that either
   defines a "__call__" (that would need to be a
   Python defined class) or an "index_html" (this
   may be a non-persistent ZClass).
