[Zope-dev] ZPatterns, Racks, Customizers, etc.

[Bill Anderson]

Looking for some docs, however incomplete, on programmatically (DTML OR
Python) add a Specialist (or Specialist Derived ZClass) and set up teh
defaultRack, and add a Skinscript/Trigger.

I would also like to be able to set the ZClass storage too ...

That's not asking much, is i ? :)

 the two versions in synch and make sure the translations are done on time

 Its seems that Zope might help manage these kinds of projects - by smoothing
 the workflow - tracking what needs translation, perhaps sending stuff to the
 translator automatically, reporting on what's been done by who and comparing
 the two language versions to make sure they are parallel. And perhaps even
 sharing a common architecture - so that you didn't need two sets of DTML
 methods etc.

 I'm wondering if this fits into other generic Zope workflow products that
 people have talked about developing or if it would have to be built from
 scratch.

 Anyone have thoughts on this subject?

Yes. Look at our bilingual site at http://www.petr.com
In the url: http://z.petr.com/buro/p/index_html?language=en
the parameter 'language' is available in the whole object tree.
Only text modules need to know how to react on this parameter.
Pages, images, navigation, templates etc. are not aware of the language
(though they may if needed, e.g. changing the layout)
So there in only one tree of pages, one set of navigation.
The text modules have syntax like:

dtml-if "getform('language') == 'nl'"De kracht van het werken met klein
team...
dtml-elseThe strength of working with a small team...
/dtml-if

Pages only contain references to text modules and the name of a template
to be used.

[Zope-dev] Question: How can instatiate a Zclass from python.

[Harry]

I am creating an external method in python and I want to add a product (in
that method) which is a Zclass (only, it doesn't exists in the
lib/python/Products directory). How can I instatiate this object and how
can I overide the name error that will occur (because I haven't import
anything)?

Thank you very much,

Re: [Zope-dev] Re: [Zope] Multi-lingual sites and workflow

[Holger Lehmann]

Guys, please !

Try to use the translator:

your folder/
  /translator   --- product translator
  /en/   --- DTML-Methods returning the  
strings/pages for english
  /fr/ --- DTML-Methods returning the
   strings/pages for french
  /de/ --- DTML-Methods returning the
   strings/pages for german
  /nl/ --- DTML-Methods returning the
   strings/pages for netherlands

So now you do have the e.g. index_html  in your folder (content between 
):

dtml-var header !-- your standard header --
h1dtml-lvar welcomeh1!-- your welcome message notice the dtml-lvar 
call instead dtml-var --
a href="dtml-lvar mainpage url"dtml-lvar mainlinktext/a !-- mainpage 
being the document you want to link to and mainlinktext the text for the link 
--
dtml-var footer   !-- your standard header --


Now lets walk trough this example.
In en/welcome is the following (between the ):

Welcome to my page.


In  en/mainpage is some document with images, text forms, whatever.
In en/mainlinktext is (content between ):

Go to main page.


What happens if someone with english prefs set in browser visits you page ?

Easy: dtml-lvar calls get expanded to language/variable content instead 
of variable content like a dtml-var would do:
--
. header 
h1Welcome to my page/h1
a href="en/mainpage"Go to main page./a
 footer 
---

No if someone from France with fr prefs set in the browser the link would 
change to fr/mainpage and all text would be taken from the french versions.

It is extremely powerful. The language directories can contain any kind of 
object you can put in a folder - they are nothing special. Only the 
translator is nessecary since it provides the dmtl-lvar method.

We have already created a german/english website using a bunch of squishdots, 
metapublishers and whatnot without having big trouble. We had to change a 
couple of products to use dtml-lvar instead of static text, but apart from 
that

Only if you've deleted the title property on the properties screen.  By

Re: [Zope-dev] ZPatterns, Racks, Customizers, etc.

[Steve Spicklemire]

Would something like this work?

newSpecialist = Specialists.Specialist()
newSpecialist.id = 'goobers'
newSpecialist.title = "Goober Manager"

myFolder._setObject(newSpecialist.id, newSpecialist)

newSpecialist = newSpecialist.__of__(myFolder)
newSpecialist.RacksGroup._constructPlugIn('Rack', id='defaultRack')

newRack = newSpecialist.defaultRack
newRack.manage_addSSMethod('mySSMethod','')

Most of this can be 'gotten' by poking around in the HTML documents
in the management interface

[Zope-dev] Moving ZClass app to 2.2.2

[Jason Spisak]

Zopists,

When I start up Zope with my .zexp of my ZClass based product from 2.0 I
get this message. 


2000-10-27T23:36:46 ERROR(200) Zope Couldn't install Staff
Traceback (innermost last):

SystemError: Failed to import class _ZClass_for_CatalogAware from module

 Everything works, I can get my data in and out.  Only I get some strange
behavior from the CatalogAware zclasses (they don't pay attention to the
"sort" attribute of searches for example)

Is there anything I can do to make the move to 2.2.2 100%? Put a phantom
class in the ZCatalog folder?


All my best,

Jason Spisak

No, __init__ is called at parse time and has no knowledge of the surrounding
environment.  render\__call__ is called at render time when the namespace
becomes important.

[Zope-dev] another debugging howto, and a question

[Simon Michael]

Here are some draft howto-like things some might find helpful
(improvements welcome) :

http://zwiki.org/ZopeDebuggingRoadmap
http://zwiki.org/HowToDebugZopeInEmacs

and a burning question:

how can I invoke zserver such that I will get the interactive debug
prompt ? I'd like to have my breakpoints trigger when I access the
server in the normal way with a web browser, poke around, let it run
on and do it again. I was able to do this in the past and it's useful.

Many thanks!

[Zope-dev] Documentation Documentation

[Michel Pelletier]

Greetings,

Amos and I have done some work in the fishbowl this week.  We have
started a new project to define the process for writing Zope
documentation.

This fishbowl project can be found at:

http://dev.zope.org/Wikis/DevSite/Projects/DocumentationProcess/FrontPage

The idea here is to open up as much as possible the process for
determining the process of writing documentation.  In case you don't
follow that, let me put it a different way: We are using the Zope
fishbowl process to develop a *new* process for writing documentation. 
One of the goals of this new process is to work itself into the existing
fishbowl process for Zope projects, so that everyone has a clear
documentation vision.  All this gets a bit weird; meta-documentation and
developing a process with The Process in order to modify The Process,
but you'll get the idea if you read the wiki.

What this is *not* is a roadmap for existing or future documentation
artifacts.   In other words, if you looking for juicy bits on the
Developer's Guide or some other discreet Zope documentation artifact,
you won't find it here.  Because no process exists yet for writing
documentation, we have not addressed these issues.  When this project is
completed, we will have a complete roadmap that everyone can understand
for writing documentation, and then we will address the issues of actual
documentation artifacts, like where they belong in CVS and format issues
etc.

So please check it out and leave your comments in the Wiki.

Thanks,

-Michel

[Zope-dev] zwiki 0.7.0 bugfix

[Simon Michael]

this should resolve a problem with the recent release. From
http://zwiki.org/FrontPageNews:

"The original (pre-0.7.0) problem was this: in dtml modes, initial
lines containing : followed by a blank line were not rendered (because
they were considered to be http headers).

The symptoms of my interim fix in 0.7.0 are this: ^M's appear at the
beginning of pages and blank lines sometimes get eaten.

I think I have a suitably ugly workaround now. It's running here and
available in http://zwiki.org/zwikidir/releases/ZWiki-0.7.1rc3.tgz,
please try it out."

All of them ;-)

On Linux each thread does _NOT_ get a copy of the
ODB. It just _looks_ like it.

I suspect you are referring to the characteristic that several Linux
memory-reporting tools list the memory used by one Zope process once
for each thread.

That's not the characteristic I am referring toEach zope publisher
thread really does have its own copy of the ZODB object cache.

You can verify this by checking the value "Total number of objects in
all of the caches combined" from Control Panel. This number should be
roughly (number of threads) * (target size), although there are many
factors that can affect it.

See the archives for details. The benefit
from smaller thread counts is that:
A) Multiple threads is not a big boost on uniprocessor machines

This is only true if Zope is saturating your processor. It may not be
true if you are publishing any methods that are mostly I/O (file
access, or other web requests)

B) Python does some different things with threads, see the Global
Interpreter Lock for details. Changin the realted value in Zope will
acheive differing levels of performance.

Re: [Zope] Mapping tools and Zope - SIG? Fishbowl?

[Philipp Auersperg]

Hi Trevor!

That is an interesting question, we had a GIS project in the beginning of this year 
where we worked with and
extended PMS (Practical Map Server from ArsDigita) .

On our demo site we run the project (BlueGis) together with Zope (check out 
www.bluedynamics.com, 
exactly:http://www2.bluedynamics.com:8080/BlueDynamics/products/bluegis/BlueGis).

PMS has a very elegant clear structure, but it is written in java (unfortunately java 
has stability problems under linux and PMS 
sometimes locks up).

We had the vision to 'pythonize' PMS, since the architecture and concept of PMS should 
be well portable
to the Python/Zope world, but had unfortunately not enough timemoney to do that on 
our own.

I am very happy to see that there exists interest in that direction and perhaps there 
will be the opportunity to
pythonize PMS. 

Regards
phil

display, cartography, spatial analysis, etc. Obviously our interest here
is web interfaces, but these other products are testimony to the
ubiquitous nature of the problem; a good suite of comprehensive GIS
software solutions just doesn't exist, either for free or commercially
(IMHO). The approach my team will likely take on our project will be to
examine existing open source products and determine if there is one that
is sufficient to meet our needs and simply use it. If we can build some
tools around this product to facilitate it's future use with Zope by
others, we will open source those.

I would welcome the discussion of this issue, since it is important and
it is one of the up and coming needs for web applications. I would
welcome feedback from others who undoubtedly have significant experience
and knowledge to bring to this problem.

[Zope] ZOracleDA causing instability

[Petru Paler]

Hi,

Just wondering if anyone else sees this: I run a moderately high-traffic (a
couple hundred thousand hits/day) with Zope and Oracle (most of the site is
forms interacting with the Oracle database, the rest being help/support files
for those forms and a couple images). Products used:

  - FSSession-0-4-2
  - GenericUserFolder 1-2-4
  - PythonMethod-0-1-7
  - SiteAccess-2-0-0b3
  - the latest ZOracleDA (the __version__ string in __init__.py says:
"$Revision: 1.4 $")

Zope 2.2.2 (source release) run with RewriteRule proxying behind apache 1.3.14.
Oracle 8.1.6 (aka 8i release 2) installed on the same machine.

The problem is that the whole thing is very unstable, and I suspect ZOracleDA
to be the culprit. Sometimes the whole Zope just hangs (actually so often, that
we are restarting it from cron each 15 minutes, but it's a bad solution since
all the GUF cookies are lost and customers are logged out), other times it
goes mad and eats lots of memory (I've seen it consuming 800 megs of memory,
and the whole unpacked Data.fs is 9 megs!), other times it gives a very strange
error: ZSQL methods raise exceptions whose contents is queries ran in other
threads!.

Does anyone have any ideea of what is happening, and how to fix it ?

I think we're reaching a point where we'll soon be able to release a

none of the current ones work properly with Python 2.0.

Yes, Zope needs a cPickle newer than the one in 1.5.2, but the one in
2.0 is newer still.

Remove the reference to cPickle and cStringIO, and everything* will
compile and run ok.

I've got a system-wide installation of Python 2.0 and the

[Zope] [alpha] Allaire Homesite integration with Zope

[Ben Schochet]

Are you a Homesite 4.5.1 user that wants an integrated Zope editing environment? 

Please try out my very preliminary attempt at integrating these two great products 
http://www.zope.org/Members/bens/homesite_editor_for_zope. This is a very early 
attempt at making a full-fledged dtml editor. This will allow you to edit Zope files 
through FTP with dtml color highlighting, dtml validation, dtml wizards, attribute 
inspectors and more. I think you will find that even in this early stage this will 
help your Zope productivity. I have a huge list of To-Do items for these extensions 
that will make Homesite as good an editor for Zope as it is for Cold Fusion. 

Need for easy Zope editor
While the ability to edit dtml document through the web is great, I have found the 
lack of ability to create dtml files in my favorite html editor disappointing. 
Homesite is the undisputed editor of choice for most client side web developers (on 
windows). It has great support for html, css, js, and a bunch of flavors of xml. I 
started this project enthusiastically with the goal of making dtml a first class 
citizen on Homesite. 

Community project:
Because of the demands on my time and the large list of features that need to be added 
to this project I’m hoping for a lot of help from the community. As a user I want this 
project complete as soon as possible. Which is why I am releasing this less than half 
finished project very prematurely so we can all spin some Open Source magic together. 
Please send me your thoughts at [EMAIL PROTECTED]

Everyone can contribute:
This project needs help with graphic design, html production, JavaScript and css, and 
of course Zope programming. Also putting together documentation and help screens from 
the vast body of Zope literature. I have big plans for this and could use all the help 
you can give.

Benefit to the Zope community:
A better Zope development environment might draw the “Site Builders” of the world to 
Zope. Currently most are creating sites with inferior technologies like Cold Fusion 
and ASP because of their good developer tools and familiarity of the development 
interface. I think the majority of web developers are afraid of seemingly complicated 
technologies like Zope. Our effort could create the tool that allows people with 
limited development experience to give Zope a try.

Please try it out and send me feedback, comments, and suggestions. 
Thanks.
-Ben Schochet.

[Zope] ZSql Strange Error

[Cesar A. K. Grossmann]

Hi!

I'm trying to emulate an outter join in a Z SQL, but Zope crashes every
time I try the query.

The query is defined as:

-*-*-

parameters: username
query definition:

select codigo, nome, 'T' as select
from cad_exportacao
where codigo in ( 
select codigo
from user_codigo
where username = dtml-sqlvar username type=string
and tipo = 'E' )
union all
select codigo, nome, 'F' as select
from cad_exportacao
where codigo not in ( 
select codigo
from user_codigo
where username = dtml-sqlvar username type=string
and tipo = 'E' )

-*-*-

The log messages says there's not a 'cad_exportacao' relation (that is
not true, the relation exists).

Zope 2.2, Linux 2.2, PostgreSQL 7.0, ZyGreSQLDA 0.03 (from the README).

What is wrong? What I can do to get the job done (I need to fill an
multiselect with 'codigo', 'nome' from 'cad_exportacao', and if exists
any 'codigo' for 'username' in 'user_codigo', the option must be
selected - I tryed the "Filling MULTIPLE SELECT ... HOWTO', but it
doesn't works for me, and I don't know why)?

TIA

[Zope] CMS/publishing system

[Pete Prodoehl]

[Note: this was also sent to [EMAIL PROTECTED]/Content Management System
Mailing List]

I'm looking for opinions on Zope being used as a CMS/publishing system.
Here's some rough notes on our situation and my thoughts on Zope.

We run NT now, but would like the option of migrating to *nix. (Zope runs on
both.)

We want to deploy across 50+ sites. (Since it's open source, we'd spend our
money on customization/development rather than licensing fees.)

We'd prefer a browser based administration system. (Zope's already got a
very good one.)

Some questions I have are:

How well does Zope integrate applications/cgi's written in ASP, Cold Fusion,
Perl, etc...? As we've got a number of things we'd prefer to keep as is, and
run alongside Zope.

How does Zope deal with serving virtual domains off of a single NT box? What
approach would that require?

Zope looks like a really nice platform, any real-world evaluations would be
most appreciated...
(Besides what I've read on www.zope.org)

thanks...


Pete

Re: [Zope] [alpha] Allaire Homesite integration with Zope

[complaw]

 Are you a Homesite 4.5.1 user that wants an integrated Zope editing 
 environment? 

While all of this is great if you've paid $$$ for both Windows and Home Site,
this doesn't help out the majority of Zope users who don't have either.  How
about modifying an existing open source editor that is cross platform and use
that?  At least that way, Allaire wouldn't be able to do something against you
because Zope competes with Cold Fusion.

Don't get me wrong, I thing that having a separate DTML editor (that also
understands HTML) is a very good thing.  I want that myself.  I just think that
you are opening yourself up to a lot of heartache because it is all too easy for
Allaire (who owns both Home Site and Cold Fusion) to destroy the project.  I
would love to have the capability you espouse, but I'm not Sysiphus.  I would
rather devote my time and effort into something that I know couldn't be taken
away from me.

Just my $0.02.

[Zope] Survey data to SQL - a trouble...

[Alexander Chelnokov]

Hello All,

Problem: In a multiform survey values have to be saved into SQL DB
after last form is finished. So data have to be passed from a form to
next forms. Except this, each form must "know" which survey it belongs
to (SID is an unique survey ID) and a reference ID of the next form. If
it is last form, the reference is empty.

Solution: values of fields of previous forms and service data (SID and
a next form ID) are saved to INPUT TYPE="HIDDEN".
When the last form is completed, from REQUEST.form.items() we need to
extract only data fileds, without SIDs and IDs of forms. It is done by
filter.py:
==
def filterList (list): 
fl = list
res = []
for el in fl:
  if el[0] not in ['sid','form','submit','nform']:
 res.append(el)
return res
==

The Python method is called from this DTML-method:

==
dtml-let fl="filterList(REQUEST.form.items())"
dtml-call "storeResultsSQL(table_name=id, 
fields=fl,
sid=REQUEST['sid'])"
/dtml-let
==
This seems to work.

Then this SQL-Method has to save data:
==
Arguments: table-name, fields, sid

UPDATE dtml-var table_name SET
dtml-in fields
dtml-var sequence-key=dtml-sqlvar sequence-item type=nb
dtml-unless sequence-last, /dtml-unless
/dtml-in
==

And after this piece of code an error appears:

Error Type: TypeError
Error Value: getattr, argument 2: expected string, int found

Traceback:


  File D:\TESTSITE\lib\python\DocumentTemplate\DT_Let.py, line 147, in render

Any suggestions?

Is there a way of checking the base classes of an object from python?

Or perhaps I should be doing this differently...

Cheers,

seb

[Zope] PIL and sizing image

[brocken22]

Hallo, 
that's what I like:the user sends a graphic and we are creating a
news-item with a thumbnail and a printable one.So I installed PIL and tried the
following:

#bildk.py
import PIL.Image

def bildk(graffik,modus):
im = PIL.Image.open(graffik)
im.thumbnail((100,100))
#if modus = 'gif':
#   im.format = 'GIF'
#else:
#im.format= 'JPEG'
return im

Error Type: IOError
Error Value: [Errno 2] No such file or directory: 'header.gif'

That's right cause I pass the image-object from within Zope and not from
the local filesystem.
Am I forced to save the thumbnail locally and reimport it??
There must be a better solution.
Thanks!!

[Zope] images in directories

[CURTIS David]

Hi,
I check the archives but could not find an answer.  How do you display images that are 
burried in directories?
For example,  
dtml-var image1 works with the image1 at same level
but 
dtml-var /IMAGES/image1 does not.  nor does
dtml-var IMAGES/image1
Any help would be apprechiated.  Thanks in advance

[Zope] How do I create an object instance with DTML?

[Danny William Adair]

Hi yall,

I want to cover Zope's management screens from the (managing) user, and only
take parts of its functionality and change its design so that there is a
folder in which the user has simple cs functionality and won't be overdosed
with options.

In this folder now, I would like to create an object instance of (among
others) STX_Document with a DTML Method. I would also like to set its
security settings! Will I need an external method? How would I do this? I
have subclassed "Folder" and added a method "add" with which I want to add
new objects to the current "xFolder". Furthermore, I've added an index_html
DTML Document which will render the "folder's view" the way I want it to be.
Does this approach seem acceptable for my purpose?

tia,

CU+Prost,

When you create your image object set the path correctly then your
dtml-var image1 should work :)

Look at the dtml source for the management screens and you'll pick up how to do all 
this.  Also refer to Zope Quick Reference (http://zdp.zope.org/projects/zqr/ZopeQR) 
for more methods than you can shake a stick at, e.g.:

  manage_addDTMLDocument(id, [title, file, REQUEST, submit])
  manage_changePermissions(REQUEST)

[Zope] Re: [Zope-dev] Re: [Zope] Multi-lingual sites and workflow

[Holger Lehmann]

Hi Petr,

Am Donnerstag,  2. November 2000 14:49 schrieb Petr van Blokland:
 Holger, thanks for the reply.
 Some questions:
 - Where is the Translator product avalaible.

Please visit
http://www.zope.org/Members/fog/Translator

 - What is I want to change from one language page to the same
 page with a different language. I don't want to change the settings
 in the browser for it.

Translator supports the standard browser settings as well as a cookie based 
version. It comes with a fully fledged demo that demonstrates this cookie 
stuff. For me it was cut, copy and paste from there on :-)

Make sure you check out www.vitaminic.com to see how it feels like :-) They 
did their site using Zope and Translator with cookies.

 - It seems that you have different folders per language containing
 all things for that language. That is not what we want. I want to have
 one folder structure where the different language versions of a text
 a in the same document or folder.

Sorry, no way :-(
But let me see if I can argue with you :-)

Yes, you can put it all in one directory and into on document.

But, just imagine this:
You have the "templates" in you main directory and only (!) a bunch of 
DTML-Methods located in the subfolders en,de,nl,fr,es and so on. These 
DTML-Methods only return a simple String or a small part of your document 
translated properly.
This enables you to choose different images for different languages for 
example.
Furthermore you can "give" someone a copy of your default language folder and 
as him/her to translate it. This can be done in parallel without people 
having the need to change the original templates.

Now if you do not like all the DMLT-Methods, you can simple create a e.g. en 
folder and use properties attached to that folder to hold your translations.

If you do not like to have folders flying around, you can create them 
*inside* the translator. But please notice, you cannot have them outside as 
well as inside, the inside ones will always be the ones used, Translator will 
not seek any other folders once he found one.

The translator itself has another way of storing translated text. It is 
accesible on the Translate tab inside the translator. IMHO the translator has 
a very clumsy interface there so I never used it. But it might be cool as 
well, since you could be able to export this data as XML and reimport it once 
it is translated.

Anyway, whatever you do make shure you check it out and give yourself a day 
to waste on the translator to find out all possiple ways to play around. I 
had a lot of fun with it up to now and it works absolutely reliably.
Even the highest educated people in our company think this product is well 
designed to support multi lingual features so easily (apart from a fwe 
enhancements they would like to see :-))) )

RE: [Zope] Products : dependencies (or who's on first?)

[Seb Bacon]

 Okay, here goes :

 I installed the PTK product some time ago, decided that it wasn't where I
 needed to be right now and moved on to something else.

 Today I finally decided to delete it from my Products folder. Shortly
 afterwards, I noticed that both my existing FlexFAQ and ZDiscussion
 objects were "broken" (with the little broken icons in the manager
 view.) and Zope was spewing errors to STDOUT complaining that it "Could
 not load oid" (I'm sorry, I don't have the traceback...doh!)

snip

OK, here goes for an almost completely useless answer based on guesswork and
half-memories.  More of an extra call for help from the zope experts,
really.

AFAIK this kind of problem is caused by incorrect management of products.
For example,   you'll get grief if you delete a product from the control
panel but it still exists in your products folder in your zope distribution.
I guess the ZODB is somehow out of sync with the filesystem, and this is why
you're getting 'dependency' errors.

Umm, help me out someone - this is all guesswork on my part...

As for solutions, some people have suggested sorting the problem out by
going into the ZODB itself via an interactive python shell and poking around
(there was a recent mail about this on the list).  If all else fails, you
could try getting a fresh Data.fs and importing your old data into it, and
reinstalling the products you use.  I too have learned the hard way, and now
I back up my Data.fs before messing with products beyond my ken, but this is
of course not helpful advice for you right now.

This problem comes up again and again.  If my guesswork is right g then
this is all because the product management process is ambiguous,
undocumented (...), and lets you do things you shouldn't.  Is there a HOWTO
on this anywhere?  Should product management be easier?  Should there at
least be some warnings added at appropriate places in the interface?  Or
have I got the whole thing totally wrong?!

Hope that helped just a little bit at least ;

You can use the dtml-with tag on the folder IMAGES (because it's an object) like 
that :

dtml-width IMAGES

dtml-var image1

dtml-var image2

[Zope] Re: Multi-lingual sites and workflow

[Petr van Blokland]

Holger,
thanks, I will check it out.
Reason for the different approach is that we have to have
an aditional layer inbetween pages and modules as we call them.

We have a list of modules which are plain texts pieces that can
be on several pages in the site (and other things, they are xml based
and can be used in PDF as well).
There is one template for the whole site (which is a *complete* html
document since just headers and footers won't work most of the time).

Pages are only bindings of module names to labelnames and the
template name to be used for the page.
A typical page is:

dtml-let
 labelfeature="m.front.feature_css"
 sidenavigation="m.products.sidenavigation_css"

 label1="'m.navigation.panorama_to_building'"
 label3="'m.front.buro_address'"
 label4="'m.front.map_delft'"
 label5="'m.front.working_on_database'"

dtml-with templates
 dtml-var template_balloon_dtml
/dtml-with
/dtml-let

The site-template would contain something like:

span id="navigationtext"
 dtml-if label1
  span id="label1"dtml-var label1_to_html/span
 /dtml-if
 dtml-if label2
  span id="label2"dtml-var label2_to_html/span
 /dtml-if
/span

span id="otherlabels"
 dtml-var label3_to_html
 dtml-var label4_to_html
 dtml-var label5_to_html
 dtml-var label6_to_html
 dtml-var label7_to_html
/span

dtml-if label8
 span id="sidelabel"dtml-var label8_to_html/span
/dtml-if

One of the advantages this way is that modules take care of themselves.
Adding a parameters in the url will make all the modules add a button
to themselves as link to an editor windows on that module. Page and
template don't need to know.

This contruction has proved very flecxible, but is the opposite from
the translate approach.

Regards, Petr

  Hello all,
 
  I have setup a query form to query a small MySQL database using
  Zope.  It consists of:
 
  1.  ZMySQL Database Connection (ZMySQLDA)
  2.  ZSQL method
  3.  A search interface.
 
  Now, what I want is the user to have the option of viewing the
  results in HTML or raw XML.  I think there can be two approaches
  to this:  1. External method, or 2. XML-RPC.
 
  1.  External method:  Replaces the ZMySQL database connection
  with an external Python function called 'mysqldb_XML', pieces
  of which follow:
 
  def mysqldb_XML(self,query):
  """
  Use a MySQL SAX driver to map relational data to XML.
  Hacked from PyXML saxdemo.py.  The MySQL driver is a modified
  version of Sean McGrath's drv_mysql.py ("XML Processing with
  Python").
  """
  from xml.sax import saxexts, saxlib, saxutils, writer
  import sys,urllib
 
  #Our MySQLdb XML driver;
  driver="xml.sax.drivers.drv_mysqldb"
  .
  out = sys.stdout;
  p=saxexts.make_parser(driver)
  dh=writer.PrettyPrinter(out,dtdinfo=info)
  try:
  p.setDocumentHandler(dh)
  return p.parse(query)
  except IOError,e:
  return in_sysID+": "+str(e)
  except saxlib.SAXException,e:
  return str(e)
 
  Inside Zope, I get the ZSQL 'query' and do something like:
 
  dtml-call "RESPONSE.setHeader('content-type','text/xml')"
  dtml-in "mysqldb_XML(query)"
dtml-var sequence-item
  /dtml-in
 
  2.  XML-RPC:  It seems to me XML-RPC could do this too, but
  I don't know how one would print out the raw XML response.
  Could I have a Zope client request the ZSQL method above,
  but instead of sending it to my output DTML method, I just
  print the raw-XML stream?  Examples would be helpful:-)
 
  It seems to me if XML-RPC already produces an XML formatted
  stream, it would be more efficient to just use it (unless
  there is yet another way in Zope I'm not aware of).  Is it
  possible?  Is there any reason to want to use the external
  method instead?
 
  Thanks for your comments,

Yes, its very good, but could be better. Its currently too hard wired I

 How well does Zope integrate applications/cgi's written in ASP, Cold Fusion,

Nope. You should take the chance to reimplement them. You get better
performance
and much cleaner solutions (better to maintain and more secure) then any
of the
mentioned solutions allow. Many things are better done completely
different in 
zope.

 How does Zope deal with serving virtual domains off of a single NT box? What
 approach would that require?

There are several options. One of it is site-access (product at
zope.org)
You can also server different instances of zope off the same server
(using
different ports and apache or squid in front as dispatcher)
 
 Zope looks like a really nice platform, any real-world evaluations would be
 most appreciated...

We are currently implementing a light CMS. So stay tuned... ;)

This problem stems from the quirky code generated by Web Studio, but
it forced me to access the page via a redirect rather than
incorporating it directly via dtml-var.

RE: [Zope] CMS/publishing system

[Pete Prodoehl]

 How well does Zope integrate applications/cgi's written in ASP, Cold
Fusion,
 Perl, etc...? As we've got a number of things we'd prefer to keep as is,
and
 run alongside Zope.

Nope. You should take the chance to reimplement them. You get better
performance and much cleaner solutions (better to maintain and more 
secure) then any of the mentioned solutions allow. Many things are 
better done completely different in zope.

argh... That's not a good answer. Is it possible? I'm thinking that with
Apache and mod_rewrite it would be doable (using file extensions to map the
request), but I'm not sure how that might work under IIS or within Zope...
There are some systems in place that are either, large/legacy/developed by
others/etc that we can't simply reimplement in Zope... Plus, I'd consider it
a big plus for Zope if I could run apps written in other
languages/environments without too much of a hassle.

[Zope] redirect on Authorization

[Daniel Rusch]

Is there a way of having all users redirected upon Authorization?  

Let me explian. We have a very large site and many of Users bookmark
pages. This can cause several problems especially if the site layout
changes, security changes at different levels and a user bookmarks a
result pages that depends on previous page(s) submissions.


In other words can zope be hacked to return a preselected URL instead of
the page the user has bookmarked?

1,000,000 hits is not that much but you can check out the Zope Benchmarks

On some good hardware it can handle about 100 Requests per second (8,640,000

Beyond that you need two things... ZEO and hardware.

Re: [Zope] images in directories

[Jason C. Leach]

hi

This is a bit of code I was working on, it may not be what you are after
but:


dtml-in expr="PARENTS[0].objectValues('Image')"
lidtml-var title_or_idbr/li
img src="dtml-var id"brbrbr
/dtml-in


It scans through a Folder and displays all the images it finds. If that's
not what you want, then the last line img src="dtml-var id" is
probably what you want.  With OOP Images know how to display themselves,
so all you need to do is call there ID.  Also, the PARENTS[0] allows you
to go backwards through parent folders 0 is the folder you script is in, 1
is one level back and so on.

Re: [Zope] Check for JavaScript:

[Morten W. Petersen]

[Daniel Rusch]

| Hey all,
| 
| Is there a way from zope to check to see if a user has Javascript
| enabled

Well, you may be able to set a cookie, with JavaScript, and then on
the next page load, check for that cookie via REQUEST..

I.e.:

On page 1, have a JavaScript command that sets a cookie (don't rembember
how, from the top of my head);  and subsequently, check for this cookie
on the next page:

* Use JavaScript to set a cookie on a page

* Then (optionally) refresh to a new page, and test for the cookie.

Or just have this feature on a front page or something
similar..

Hmm, come to think of it, there may be an easier way (presuming the user
hasn't turned images off):

Enter a tag, something like this:

script type="text/javascript"
// !--
document.write(
'img src="http://www.yourhost.com/js-test/session/cookie_session_id"'
);
// --
/script

Oh, and there's the obvious (and cleaner?) way of embedding a script
tag with a refresh request, something like:

script type="text/javascript"
// !--
document.location = 'http://www.yourhost.com/javascript-index.html';
// --
/script

HTH.

Well, now.  That truly depends on what Zope would be doing.  Fire away a
couple of objectValues() and the process will kneel _a lot_ sooner.  Of
course, this you could solve with a context oriented Catalog, and moving
as much application logic as possible away from DTML (not that you should
put it there in the first place).
 
 Beyond that you need two things... ZEO and hardware.

And good programmers...

Is there a way of checking the base classes of an object from python?

Your description is a bit vague, but here goes, when calling objectValues()
you can give it a parameter:

objectValues('Folder')

or for several "Meta Types":

I've sketched the following upgrade path for our Zope server which
eventually should host multiple ten/hundred thousand websites:
- At the moment, I have a single box with Zope and a Squid cache in front
  of it. "Static" DTML pages are tagged so that Squid will cache their
  rendition - this increased the throughput by a factor of ~6 on my box. 
- Move Squid on a separate box.
- Move mySQL on a separate box.
- Move ZODB on a separate box (ZEO).
- Put a Linux Virtual Server director in front of your Squid box,
  and start adding Squid/Zope boxes (I figure ~3 Squid boxes per Zope
  box, depends on the amount of interactive content you've got) under
  the same IP.

On my home box (Dual PII/400, 256Mb RAM) I can do 120 hits per
second at the moment (with everything - Zope, Squid, mySQL, DNS *and*
the testing scripts running 5,000 normal websites and 95,000 "under
construction" sites), and I figure that I'll easily scale to twenty times
that much on a Linux Virtual Server cluster with all functions on separated
boxes (that are optimized for their tasks).

A page I'm working on to trouble shoot user problems when using our

the javascript, I have not tested to see if it sets that value every

shooting page is user's cache settings and when to reload pages.  The

[Zope] Can't create ZClass from within Member folders???

[chip johansen]

I have the PTK.8 installed with Zope 2.2.

I have created a demo portal and implemented membership using ZODBMembership 
Folders.

I have also created several folderish ZClasses to use as content types. I 
have given the add methods of these classes "manager" proxy.  I also created 
some user interfaces for adding these content instances from the app rather 
than the management interface.

The problem is that a user with "manager" role can create and delete content 
instances from within the app while in their member user folder or from the 
management interface, but users with "Member" role can only do so from 
within the management interface, but not the interface I created to be 
called from within there folder.

The funny thing is that if I create a copy of these methods at a level above 
the "Members" folder, it works fine, but go down 2 levels to the 
Members/user folder and it won't let me do it.

I have given every method involved "manager" proxy, and just for the heck of 
it, given "Member" the same permissions as "manager" from the top level 
down, but I still get prompted for authentication when I try to add or 
delete an instance from my method

Is it something particular to the Members/users folders of the PTK or am I 
missing something else?  I would appreciate any insight.

Thanks, Chip Johansen

[Zope] ZServer log buffer?

[Júlio Dinis Silva]

Hi all.

Supose you are saving z2.log on a mounted disk, either nfs linux or a WinNT 
cluster network name. If for some seconds that mounted disk became 
unavailable, isnt supose ZServer log system to buffer a little until the 
mounted resource became available again?
I'm dealing with the problem that z2.log "write system" on NT are giving me 
a IOError when the resource becames unavailable for some seconds.

If there isnt anything already to fix this, wouldnt be good if ZServer 
buffer a "little" until the resource became available and in the case the 
resource just completelly cease to be then ZServer just stop to write logs, 
instead of killing the process raising the exception?

I know what you are thinking: just dont permit the resource to became 
unavailable dude! But supose you have active-passive resources in case of 
fail down and you need some seconds to automatically or by hand(not the 
case) fix the resource, wouldnt be nice for ZSERVER to, for instance, stop 
logging.

Maybe this should not be addressed to Zope Log writes. Maybe
this is more a system administration issue but...

Thanx anyway for some comments.

[Zope] re-releasing mysqlUserFolder 0.5 ??

[Dennis Nichols]

[EMAIL PROTECTED], vladap (who is listed as the author) -

Just before zope.org's Data.fs developed that short circuit a day or two 
ago, there was a new revision of mysqlUserFolder released (0.5.0 if I 
remember correctly). I'd like to try it out if we could get it back on the 
Zope site.

[Zope] Zope for medium/large sites

[Tiago Antão]

Hi!

  We're considering using zope for a somewhat large project:
It's a VPN for arround 10.000 institutions ( 100.000 users expected,
up to 1.500.000 users possible, but not likely). Hundreds of simultaneous
connections expected.
The database has to support 100.000 users and a LOT of content (more
than 1000 virtual hosts, along with a very big main site).

  The question is: Is zope up to this? And yes, the necessary hardware is
available 8-). We've used Zope for smallish internal projects, but for
something as this...

Best regards,
Tiago

  Great I agree completely, except if the client has Java/JavaScript

This is a beautifuly simple solution the only things I could think of to 
improve it is:

1) comment out your javascript.
It's not required, true, but it's a sensible safety measure.

2) put the meta tag in a noscript tag.
Again, this is for extra safety... you just never know. (o8

In fact... this is the first time i've seen a META tag usage I condone... 
otherwise they just seem pointless to me. (o8


 Oleg.

Have a better one,

[Zope] Securing an FTP server.

[Jason C. Leach]

hi,

I'd like to secure the FTP server so that when Bob loges in, he is sent to
folder X and can not exit X.  And when Jain loges in, she is put into Y
and can not exit that folder.  

Is this possible.  Someone once suggested working with site rules, but
that's a bit hokey; unless someone has implemented an elagent solution like
this.

Thanks,
j.
