[Zope-dev] Adding execute() to Zope DA's for use by External methods

2000-11-14 Thread Brad Clements

I have Python code that I use outside of Zope, and inside Zope via 
external methods. This code uses database adapters (anything version 
1 or later).

When my code is used within Zope, I have in the past had two database 
connections from within the Zope process. One connection is the actual 
Zope DA (I'm using gvib) and the other is a python db connection.

This has worked okay on Windows, but I'm getting strange lockup 
problems after moving to Linux.

In any case, it seems to me the better way to do this would be to allow 
external methods to get  db-like access to a zope DA.

Most Zope DA's are built in db-sig type db connectors, so it seems like 
a relatively simple matter to define a new interface for Zope DA's to 
make available that supports execute semantics.

The big issue in my mind is determining what kind of security needs to 
be applied to such a function, and how that security would be 
implemented.

I suppose stealing roles/rights from SQL_Methods for use here makes 
sense. If you can call an SQL method, you can call execute() directly.

Is there any support from the Zope community to add execute() like 
operations to Zope DA's?

If yes, where should I start in figuring out security for this.

And finally, how does an external method pass security information 
"back" to the DA?

For example, I tried passing my Gvib instance to an external method. 
But when that method called  the gvib instance to get a connection 
instance, it got a "no __call__ method" error.

So then I tried passing the connection from dtml,
ie
dtml-var "MyMethod(db=MyInterbaseConnection())"

but when MyMethod calls db.cursor() it gets a security error. Probably 
because this function isn't exposed by the security machinery.

(same thing probably for the __call__ error)

Juan, thanks for shining some light towards this murky area. Maybe
ZWiki and other zope products need to be LGPL or dual-licensed, maybe
the zope license can use some refinement. I for one won't know without

[Zope-dev] Two glaring omissions

2000-11-14 Thread Alexander Limi

Hi,

I've been working with Zope for almost two years now, and there are two
things that I feel is missing in the interface:

1. The ability to add a Base class after the class is created

2. The ability to rename properties after instances of the classes have
   been created (and have the data in those fields preserved)

Are there any technical reasons why these are not present? I know it is
possible to add base classes in retrospect via the hack described in

http://www.zope.org/Members/AlexR/ChangingBaseClasses

but are there plans for making this easier? 

As for #2, it is quite annoying and counter-productive not being able to
change a variable name that was decided a long time ago, or maybe by
others simply because there exist instantiated objects of that type.

Both of the above are pretty essential OO techniques (for me, at least),
and hinder my work quite a lot by not being there.

Any chance of these being fixed at all? Or are there reasons that I do not
know about that makes this impossible?

Alexander Limi wrote:

 things that I feel is missing in the interface:
 
 1. The ability to add a Base class after the class is created

This is a feature we'd like to have, but the way ZClasses work currently
makes it dangerous.  What gets pickled in the ZODB isn't information
about the class, it's the class itself.  In order to change bases
safely, you'd have to try to reverse-engineer the original parameters
for creating the class object as well as all changes made afterward,
then modify the parameters slightly and construct a new class.  That's
what the published hack essentially does.

Another pitfall of storing the class itself in the ZODB is that if any
of the bases disappear, the ZClass can no longer be loaded.

If these two issues are important enough, we have a good reason to
consider a new kind of ZClass.  With "lightweight" ZClasses, class data
would be stored in a meta-class object.  The meta-class would construct
the class instance.  Changes bases and failing gracefully when a base
disappears should be easy.

The part that may still be hard is getting object instances to sync up
with the ZClass immediately when the user has changed the ZClass. 
ZClasses are good at that, you see.

 2. The ability to rename properties after instances of the classes have
been created (and have the data in those fields preserved)

This is also more difficult than it sounds.  You'd have to either scan
through the entire ZODB and modify class instances or associate
properties with a magical, unchanging ID.  The latter solution is dead
wrong, but the first is actually kind of interesting.  If there were a
separate index for each object type in the ZODB, it would be possible. 
In fact, when ZODB is running from a relational database, there is
indeed a way to do that.  Hmmm...

Not that I have the time to work on these things.  I'm swamped.  Anyone
want to draft a proposal?

  Using context.this().id, self.this().id, m_self.this().id all get me
  the same things:

If it is indeed a DTML Document, then "this()" should reference

  Did you mean to do a this().id?  That doesn't work at all, it gives

No.
I am not yet familiar with PythonMethods and what binding
they define automatically. Obviously, you have
"context", "m_self" and "self".
My older PythonMethods installed seem to support only "self",
but I am not sure.

I would expect, that "context.this()" has the highest chance
of success, maybe "self.this()".

Note, that "foo_html" must be a DTML Document not a DTML Method!


  There *must* be a way to do this.
There is none for DTML Methods (other than modifying the code).

  The only information about your caller that you can get is

  explicitly passing the namespace (or this(), for that

Why can't I get the acquisition context as with External Methods?
(if they are called directly via the Web, namespaces are not

parameter is everything I have).

 what i would like to know is, is this possible? if it is, how

[Zope] Problems with Zope 2.2.2 and MS SQL Server

2000-11-14 Thread Pieter Claerhout

Hello all,

I'm having some troubles connecting Zope 2.2.2 to Microsoft SQL Server. I downloaded 
and installed the product ZODBCDA, and I was able to connect to the SQL Server. I was 
able to define the SQL methods, and when I test them, everything is successful. The 
problem is that when I use for example the dtml-in tag to iterate over the results, 
and display them in a page, I am always prompted for a password, but I can enter 
whatever password I want, I can never get through.

Does anybody has an idea of what I'm doing wrong and how I can solve it??

 I just did an experiment and if I do the following my SQL Method:

...because you're missing some " "

REQUEST.form['FOO'] is a python expression.

dtml-if REQUEST.form['FOO'] is short for dtml-var

so, unless you have a folder or document names 'REQUEST.form['FOO']', it
will return false :-S

What you want is dtml-if "REQUEST.form['FOO']", which is short for
dtml-if expr="REQUEST.form['FOO']".

This evaluates expr as a python expression...

 If I do:
 dtml-if "REQUEST.form['FOO']" or dtml-if "REQUEST.form['FOO]=='1'"
 
 I get name errors with REQUEST being unknown.

...an oddity of ZSQL methods :-( The REQUEST usually gets made available
in the namespace, but in ZSQL methods, only the parameters your specify
as 'arguments' get added to the namespace. At a guess, try adding
REQUEST to the 'Arguments' list...

RE: [Zope] Referecing items in subfolders

2000-11-14 Thread Cornelis J. de Brabander

You could use:

dtml-with resources
dtml-var standard_header
/dtml-with

I would suggest, however, to reorganize your design and to put index_html in
a subfolder of a folder where standard-header and standard_footer reside and
let acquisition take care of the work.

 Subject: [Zope] Referecing items in subfolders


 Hello all,

 have a small question. Imagine you have the following folder
 structure in Zope:

 http://testserver.pclaerhout.com/index_html
 http://testserver.pclaerhout.com/resources/standard_header
 http://testserver.pclaerhout.com/resources/standard_footer

 How can I reference the standard_header document (which is in a
 subdirectory) from the index_html document, for example using a
 dtml-var standard_header?? I have the same question if the
 files in the subdirectory are for example SQL methods. I'm just
 looking for a way to separate different kinds of documents.

 Kind regards,


 Pieter

[Zope] Zope and Windows DB's = NOT! ?

2000-11-14 Thread Mark Pratt

hi,

is anybody successfully using a Windows DB such as MS SQL
server 7 with Zope? 

it seems that the ODBC adaptor is ancient and very error 
prone  so can i conclude that Zope and DB integration 
under windows is not an option?

[Zope] Authentication

2000-11-14 Thread seb bacon

This is strange: when I type 

  http://www.foo.com/roles 

as an authenticated user, Zope thinks I'm just an Anonymous user.  When I type 

  http://www.foo.com/roles/

It realises I'm authenticated.

I'm using Apache / ProxyPass on Zope 2.2.2.  Any ideas?

In general, the ODBC adapter may be old, but it works well and generally
without problems in my experience. In the Zope Book it's even claimed
that it's commercially supported! The point is just that it's single
threaded. If you need to use SQL Server 7 there also is a mxODBC
adapter, that claimed to be multithreaded. I don't know about its status
right now.

Re: [Zope] Referecing items in subfolders

2000-11-14 Thread Matt

I would have thought the dtml-with resources way was possibly a more flexible
way of organizing things such that instead of making a base product that people
duplicate and customize, all you need to do is set custom resource folders for
each person and load these into the name space of the single instance of the
product to give it a custom skin or user specific data.  It is also why most of
my base product are methods that can't hold any properties that may get
clobbered.   I tend to place headers in these user resource directories so that
they can make them as fancy as they want.  Acquisition works nicely that way.

[Zope] Re: SSL and relative links (URLs)

2000-11-14 Thread Ross Lazarus

Do a search on the zope site for ssl.

You'll find two very useful howto's - one describes the apache httpd.conf virtual host 
pixie dust using proxy and proxyrewrite
directives (you need to build apache with mod_rewrite and mod_proxy as well as 
mod_ssl) and the other has some details on
integrating the siteroot product to do the url munging in zope - be warned that the 
siteroot product can lead to some interesting
consequences if it isn't installed just right - it works a treat now but I would have 
been in serious trouble if I'd tried
installing it on a production site - get it right with a development site before 
bringing it over to your production machine
particularly if your dropping it into your zope root folder.

I just finished setting this up and found these two resources solved many problems 
before I encountered them (!) although there was
the inevitable headbanging needed to get everything just rightI ended up NOT using 
fastcgi although that was my original
intention. Right now, mod_proxy allows me to serve a zope running on another machine 
(!) through ssl.

[Zope] re: requests for some dtml tags

2000-11-14 Thread Jeffrey P Shell

 From: jacintha menezes  [EMAIL PROTECTED]
 
 Hi,
  Is there any dtml tags for creating a new work space also for locking
 some page.Locking some page in the sense for second user the operations in
 that page should not be processed
 unless the process for first user is completed.If there dtml tags for these
 kindly give me
 those tags.
 
 waiting for your reply.

Regarding locking:

Do you mean in the sense that if person A wants to edit a page (like a Wiki
page), person B shouldn't be able to update the page until person A clicks
"Submit changes"?  The WriteLocking project (see the Projects area on
http://dev.zope.org/) will include an API that can be called, even from DTML
(with proper permissions), to grant an exclusive write lock to a user.

If you mean you want to protect against two HTTP requests that are operating
on the same page\object from overwriting each other in process, the built in
ZODB\ZPublisher transaction handling that's been in Zope before there was
Zope takes care of this automatically.  A REQUEST-RESPONSE cycle is treated
as a single transaction.

  Zope/DTML/Python use the PyMethod "fetchObj" much
 cooler than only via
  catalog.getpath (which is link /hfg/kkjk/)
  
  to do somthing like this:
  
  dtml-in mein Result from a canned search
  
  dtml-call
 

"REQUEST.set('meineURL',fetchObj(_,Catalog.getpath(_.int(_['sequence-item'])
  )))"convert /parent/child to an real object
 parent.child
  
  dtml-var meineURL  *** points to a ZClass
 [Base:Renderable] calling the
  Object/Class directly, which renders itself
  
  /dtml-in
  
  use something like this:
  
  Python Method: fetchObj
  
  Param: _,fetchStr, attr=None
  
  obj = _
  for p in string.split(fetchStr, '/'):
 obj = obj[p]
  if attr is None:
 return obj
  else:
 return render(_.getattr(obj, attr))

[Zope] Deleted product breaks SQL_Method Advanced tab - How to fix?

2000-11-14 Thread Brad Clements

Zope 2.2.2 binary on Linux (also shows up on Windows version)

I'm looking for suggestions on how to fix this, I can't access the 
advanced tab of any of my SQL_Methods.

I had played with some products, deleted them from the file system and 
removed them from the products list in Zope (is order important here?)

Now when I choose Advanced on any SQL Method, I get this:

ImportError

Sorry, a Zope error occurred.

Traceback (innermost last):

How can I remove this object from the zodb? How do I find it?

Any idea why SQL_Method even cares about this?

[Zope] CMS isn't word, is it? ($12M round of investment)

2000-11-14 Thread peter bengtson

"content management", says Paul
Is that word different from "content management system"? Known also as CMS?

My mother tongue is not english, but this feels like a techie (or perhaps
e-business) question of english.
I feel that if I were to deliver a management interface for a client I would
probably not give them /manage access. Rather I would give them a few
Security protected forms to fill in and work with.

Sometimes people say "Zope?? Isn't it that content mangement system tool for
portals an stuff?"

I think of a content management system as an interface to handle content
such as images and text and files etc.
And the content management system Zope has, as an interface to handle
objects and work and visualization etc.

Am I completely wrong, or is there a big confusion with these words?

 What will this mean?  First and foremost, Zope and Digital Creations will
 become very competitive, very quickly, along a number of axes. As the
 PythonLabs move indicated, we are taking aggressive steps to become a
 dramatic force in the worlds of content management, web application
 services, and Open Source leadership.  With this round, our business model
 has been validated.

Re: [Zope] Deleted product breaks SQL_Method Advanced tab - How to fix?

2000-11-14 Thread seb bacon

 
 How can I remove this object from the zodb? How do I find it?
 
 Any idea why SQL_Method even cares about this?

there was a longish thread about this recently (search for something like 'Data.fs 
corrupted?!').  the upshot was, i think, that products that haven't been written 
carefully can cause problems like this because they don't get cleaned up from the DB 
when they're erased.  seemingly random relationships between products (like yours) are 
often reported but rarely investigated.  the possible solutions suggested were:

1) truncate your FileStorage (yuk)
2) reinstall the offending product, then go into the ZODB via the debugger, and do 
some surgery (yuk)
3) export all your objects, get a fresh Data.fs, reimport them (yuk)

[Zope] Re: why DTML confusing

2000-11-14 Thread Irene Barg

To all of you that responded, I appreciate your comments.  I
will admit, after reading some of your comments, and going
back to the DTML Reference, this topic is discussed in the
section under "The special namespace variable".  Right before
my eyes, there is an example doing exactly what I wanted:

dtml-if "_['sequence-length']  20"

The dtml-in variables don't follow Zope's own rules on variable
names, but I've been told that this might change.  Beyond this,
when you need to do anything complex with DTML, the code gets
really ugly.  I have found it cleaner to just write an external
Python method to take care of such complex things like parsing
fields for wildcards, etc.. I will also look at Python Methods
and ZClasses.  

Finally, don't get me wrong.  I like Zope.  It's the best
solution I have found for through-the-web management and
program development.  I thank all of the Zope folks for that!

Cheers,
--irene

 Irene says:
 
  I get so frustrated with DTML, I want to scream.
  Please don't tell me to buy the Zope book,
  DTML should be more intuitive.
  DTML maybe the heart of Zope,
  but it's also it's achilles heel.
 
 You're right about the confusion, frustration, nor are you alone.
 Still, DTML isn't the heart of Zope, it's more like the fascia.
 DTML was intended to make the task of delivering dynamic content
 wrapped up in HTML-ish Templates easier. It evolved, and took on
 a broader scope that made it enticing for lot's of "other stuff".
 
 Like most evolution, there are obvious benefits, and some
 unfavorable outcomes. The most glaring problems show up when
 you start trying to do things that seem to be just a step or
 two more sophisticated than simple examples that "just work".
 
 There's good news. Python Methods, or whatever we end up calling
 them, make actually implementing such things as easy as Py(thon).
 For some folks, it may look like the bad news is, "Now I have to
 learn Python". In perspective, learning Python is way better than
 wading through the Zope API via DTML. Way way better.
 
 So, the moral is, keep the DTML as simple as it can be. For
 anything else, reach for another tool. Zope has bunches of them.
 
 BTW, the dtml-if "_['sequence-item'}" stuff is the tip of the
 DTML Complexity Iceberg. The sooner you get comfortable with
 Python Methods, ZClasses, etc., the happier you'll be.
 
 One last point. Python Methods (a.k.a. Restricted, Internal, or
 some other as yet unheard of alternative, which we are all
 anxiously awaiting) is an add-on at this point. Target date
 for inclusion as part of the standard "Core Zope" is Zope v.2.3.
 
 For now, see: http://www.zope.org/Members/4am/PythonMethod

Re: [Zope] Website search

Depends what you mean by easy. You can catalog objects outside of Zope
inside Zope by creating a non-persistent object. If you want to make a
search engine like google... then you'd need to write a spider to create
these objects.. no, not easy.

 Hello Zope friends.  At long last we at Digital Creations are able to
 publicly say it: we've closed a $12M round of investment:

   http://www.digicool.com/News/CRound.html

 It's out on the newswire now.  We'll start pushing it out more over the
next
 24 hours.

 This, needless to say, is a big deal, one that we've worked on really,
 really hard this year.  With the tech market downturn since March, and
with
 Open Source particularly getting a beating, it's vindicating to get good
 funding from strong partners.  When everyone else was getting wads of cash
 during the go-go times, we were quietly at work, being frugal, making
money,
 making a business case, and being profitable. We're proud to say that we
got
 our money when money was hard to find.

 Let's put it this way: Open Source business is hardly dead.  It's just
 different, and better.

 What will this mean?  First and foremost, Zope and Digital Creations will
 become very competitive, very quickly, along a number of axes. As the
 PythonLabs move indicated, we are taking aggressive steps to become a
 dramatic force in the worlds of content management, web application
 services, and Open Source leadership.  With this round, our business model
 has been validated.

 As a member of the Zope community, I view this as "the dream delivered".
 Many of us care deeply about this thing we're involved in, and sometimes
it
 feels like a longshot.  Though this is still a David vs. Goliath, David
now
 has a slingshot, and a bit of steel in his eye.  Thanks go to the folks
here
 at DC, to the Zope and Python communities, and to the companies around the
 world that are basing their business on Zope.

 Onward!

Re: [Zope] Re: [Fwd: [Zope] Re: Advanced search in ZCatalog (Micha)]

2000-11-14 Thread Andy McKay

A ZCatalog reads a classes methods, so you can only make an external method
be read if the External method is part of your ZClass. If this is the case,
simply make an external method call my_index that returns a string. Then
when object is recatalogued, ZCatalog will read that external method.

 Hi,

 Ok, I could achieve something with this approach. But
 it's not clear for me how to set the ZCatalog to
 create an index from the result of an external method.
 Can you please explain how to achieve this?

 Also, the ZCatalog queries use an "and" chain for each
 token provided (eg. if a query is requested for "a b
 c" it will be interpreted as "a" and "b" and "c"), and
 I'd like to implement an "or" chain in the queries.

 Thanks for the help,

   Due to the fact that ZCatalog can Index all

  DTML-Methods.
   But they have to return something to the catalog

   You can give this method a name like
  "PrincipiaSearchSource" or what the

   In my case I index about 10 different ZClass, 100

   Be warned you can use a DTML Method and return

   P.S.:
   If you want to call a resultObject (e.g. a ZClass)
  directly through

hello andy, hello all others who answered my post,

first of all thank you for letting me know the positive
experiences you have had with the ODBC adaptor and your
various installations. i'm relieved that Zope and window's 
DB's do work together -- and this prompted some new 
tests on my part.

their still seems to be a minor issue with an error message 
the first time we query a MS SQL 6.5 DB. a few reloads later 
everything seems to work fine. kind of weird.

guess the only major thing left is the single thread issue.

[Zope] Re: Advanced search in ZCatalog PartII

2000-11-14 Thread michael Kobald

Hi,

First Part: Create Index

First, create the index "name of mymethod" in the Catalog.
ZCatalog can only index objects he knows of !
eg. use "find item to ZCatalog" tab, use the index method or use
CatalogAware as base Class for ZClass.
Additionally you have to reindex your object if its content changes (via
DTML-Callreindex.)

What does the ZCatalog for you ?
He takes your object, applies all the indexes that are possible, and reads
his data. (so we´re back,
you have to return something from your method).

This data is store in the Catalog itself, and not in the object.

Second Part: OR Query:

mmmh, did i get you right ?

I Think it´s this way:
1. Case: looking for a or b or c - type 'a b c' as query string
2. Case: looking for a and b and c - type 'a AND b AND c' as query string
3. Case: looking for a and b or c - type 'a AND b OR c' as query string
4. Case: looking for 'a  b  c' - type '"a b c"' as query string

OR

Did you mean somthing like this ?

return self.Catalog(
   {'meta_type' :
['pressemitteilung','volltext','kommentar','kurztext'],
'rubrik_id' : self.id,
'review': 0
   }
  )

Re: [Zope] Problems with Zope 2.2.2 and MS SQL Server

2000-11-14 Thread Rik Hoekstra


 I'm having some troubles connecting Zope 2.2.2 to Microsoft SQL Server. I
downloaded and installed the product ZODBCDA, and I was able to connect to
the SQL Server. I was able to define the SQL methods, and when I test them,
everything is successful. The problem is that when I use for example the
dtml-in tag to iterate over the results, and display them in a page, I am
always prompted for a password, but I can enter whatever password I want, I
can never get through.

 Does anybody has an idea of what I'm doing wrong and how I can solve it??


Did you use a Search interface on you SQL Methods (it is a standard product
in your Zope installation)? Did  it give the same problems?

Re: [Zope] Zope and Windows DB's = NOT! ?

2000-11-14 Thread Rik Hoekstra


 hello andy, hello all others who answered my post,

 first of all thank you for letting me know the positive
 experiences you have had with the ODBC adaptor and your
 various installations. i'm relieved that Zope and window's
 DB's do work together -- and this prompted some new
 tests on my part.

 their still seems to be a minor issue with an error message
 the first time we query a MS SQL 6.5 DB. a few reloads later
 everything seems to work fine. kind of weird.

there used to be a similar issue in a previous version, that had to do with
single threads and transactions not being committed. But that was patched
long ago. That's probably not it and I know it's kind of cryptic, just
thought I'd bring it up, just in case.


 guess the only major thing left is the single thread issue.

yes, that's bad.

Rik

[Zope] ZCatalog problem on insert

2000-11-14 Thread Menard . Jean-Francois

I'm experiencing some problems with the zCatalog.  I made some customized
forms for inserting data.  Yes, I use the ...reindex_object.  And Yes, I
use ...manage_addProduct.

I can see the objects in the Catalog, but my search results are always
empty!  If I update the Catalog manually (in the "Cataloged Objects" tab),
everything is OK, until I insert data again.

It only happens when I insert data, not when I modify or delete an object.
So, as soon as I insert objects via my custom form, my Catalog search stop
working ! 

Am I the only one experiencing this problem ?

I use Catalog in a lot of sites, it's the first time I have such problem.  

Any clue would be very appreciated...  I'm supposed to demo the site
tomorrow morning... :\

[Zope] ppc.rpm built from src.rpm

2000-11-14 Thread addyd

RPM gurus?

Couldn't find Zope 2.2.2 RPMs for LinuxPPC, so attempted to create my own
from src.rpms at Jeff Rush's site.
Followed the directions given at the LinuxPPC FAQ-O-Matic. Everything
seemed to go well and it build an entire set of ppc.rpms with no error
messages. Installed the whole enchilada Zope-2.2.2-1.ppc.rpm and then the
Z-Server rpm. Everything seemed to install normally and an RPM -q shows me
they are installed. However, when I attempt to get the Manage screen by
doing the http://my.machine:8080/manage I get a Connection Refused (server
may not be accepting connections/may be busy).

The machine is up (and Apache and ProFTP are listening). What do I need to
check next?
If I can determine that the problem is NOT with the RPMs, I'd like to make
them available to the LinuxPPC community.

 Subject: [Zope] FYI: Digital Creations secures $12M round of investment


 
  Hello Zope friends.  At long last we at Digital Creations are able to
  publicly say it: we've closed a $12M round of investment:
 
http://www.digicool.com/News/CRound.html
 
  It's out on the newswire now.  We'll start pushing it out more over the
 next
  24 hours.
 
  This, needless to say, is a big deal, one that we've worked on really,
  really hard this year.  With the tech market downturn since March, and
 with
  Open Source particularly getting a beating, it's vindicating to get good
  funding from strong partners.  When everyone else was getting
 wads of cash
  during the go-go times, we were quietly at work, being frugal, making
 money,
  making a business case, and being profitable. We're proud to say that we
 got
  our money when money was hard to find.
 
  Let's put it this way: Open Source business is hardly dead.  It's just
  different, and better.
 
  What will this mean?  First and foremost, Zope and Digital
 Creations will
  become very competitive, very quickly, along a number of axes. As the
  PythonLabs move indicated, we are taking aggressive steps to become a
  dramatic force in the worlds of content management, web application
  services, and Open Source leadership.  With this round, our
 business model
  has been validated.
 
  As a member of the Zope community, I view this as "the dream delivered".
  Many of us care deeply about this thing we're involved in, and sometimes
 it
  feels like a longshot.  Though this is still a David vs. Goliath, David
 now
  has a slingshot, and a bit of steel in his eye.  Thanks go to the folks
 here
  at DC, to the Zope and Python communities, and to the companies
 around the
  world that are basing their business on Zope.
 
  Onward!

[Zope] creating ZClass instances from an external method

2000-11-14 Thread Gary Reynolds

I have a need to do some creating of objects from python code.

Am I correct in thinking that to add a new object, that is one of my
products, I need to do something like:

  folder.manage_addProduct['ProductName'](id='foo', title='bar')

I have sample code to create simple things like using
manage_addDTMLMethod, etc, but nothing for a product.

The way I've got my data stored is in a combination of dictionaries
and lists... it was an ugly enough process to export it - now
importing it seems worse.

Any help would be appreciated.

Cheers,
Gary

 "_properties" and the "__ac_permissions__" would be preferable. But anything
 will do.

Re: [Zope] DateTime problem

2000-11-14 Thread Aaron Payne

To view it as a DateTime object:

dtml-var "_.DateTime(yourstring)"

or
Create a DateTime object with an id of datestring to be rendered later.
dtml-call "REQUEST.set('datestring',_.DateTime(yourstring)"

To view it:
dtml-var datestring

DTML.  Document Template Markup Language.

DTML is Zopes templating language.  Look at DTML Documents and DTML Methods. 

Have a better one,

RE: [Zope] ZGDChart product...

2000-11-14 Thread Furbach, Andreas

Hello.

The function _chartdata in ZGDchart.py returns only one label column and one
data column. 
You may want to change this to:
*

def _chartdata(self):
"""
return the first and second columns of sql query
results as a pair of tuples
"""
rows = getattr(self, self.SQL)()
# data[0] is list of labels
data =  []
start = 0
for row in rows:
# each row is a list of fields
# initialize empty lists for each column
if start == 0:
  start = 1
  for i in range(len(row)):
data.append([])
#
# Only insert rows with zero values if
# it is not a pie chart
# Pie Chart only makes sense with 1 data column
#
for i in range(len(row)):
if (self.REQUEST['zgdchart_runtime_type'] !=
GDC_3DPIE and self.REQUEST['zgdchart_runtime_type'] != GDC_2DPIE) or row[1]
!= 0:
  #
  # Coerce the first field into a string
  # and other fields into a float
  #
  if i == 0:
  data[i].append( str  (row[i]))
  else:
  data[i].append( float(row[i]))
#
# convert lists to tuples
# apparently, gdchart.chart() accepts lists
# as well, but I better check with
# M Steed first.
#
# I just tried.
return data


***

and restart Zope, which worked for me.

Hi.

This is really a great product.

Unfortunately, I'm not able to create a chart with multiple columns using a

ZSQL Data Method.
Multiple columns with a DTML-Method works fine.

Do I miss something. Any ideas?

Thanks for any help. Regards, Marc Ludwig ([EMAIL PROTECTED])
