[Zope] Localizer 1.1.0 released

[J. David Ibáñez]

Localizer 1.1
=

April 7, 2005 - Two years after release of Localizer 1.0, I am
pleased to announce the availability of the next major version,
Localizer 1.1.

Localizer is a Zope [1] product for developers and web masters.
Localizer solves the problem of building multilingual products
and web sites, ranging from internationalization and localization
of the user interface to management of multilingual content.

jdavid at itaapy.com [2]


What's new in 1.1
-

This release brings several new features. Specifically Localizer
now supports industry standards such as TMX [3] and XLIFF [4],
which enhance the interoperability of Localizer based applications
within mainstream environments.

Native support for 'i18n' namespaces for ZPT (Zope Page Templates)
is included avoiding the need to install other products.

The user interfaces have been vastly improved, specially for
'LocalContent' objects.

Four new translations are available: Danish, Italian, Portuguese
and Russian.

Localizer 1.1 has been re-packaged and now depends on itools Python
package and iHotfix Zope product. While these changes make installation
a bit more complex, the added benefit is simplified source management.
Furthermore this subtle change makes Localizer Services available to
the wider audience of Python [5] developers.

Last but not least, Localizer's stability has been dramatically
improved by resolution of many bugs resulting in a mature and even
more reliable product.


Credits
---

This is the first release where the majority of work has been
contributed by community users and the original author. Credit
where credit is due.

To Eduardo Corrales and Roberto Quero from the Deusto University [6],
for the original implementation of the TMX standard.

To Søren Roug and Cornel Nitu from the European Environment Agency [7],
for their work on the TMX code, the implementation of the XLIFF standard,
the overhaul of the LocalContent interfaces, and the Danish translation.

To Alexey Lubimov for the Russian translation.

To Mario Olimpio de Menezes for the original Portuguese translation.

To Rodrigo Senra for updating the Portuguese translation, and for improving
the Localizer API.

To Marco Bizzarri for the Italian translation, and for improving the
stability.

[Zope] DTML namespace problem (was: dtml-tree issue)

[Vangelis Mihalopoulos]

Hello,
i have focused my problem on this:
having a Python Script "testScript":

class obj:
a = 1
b = 2
c = 3
return obj()

and a DTML Document "testWith":
---

 

---
when i try to view the DTML Document, i get an "Unauthorized" Exception.
I believe this has something to do with the security mechanism of Zope. 
What must i return from the Python Script in order for the DTML Document 
to work?

Thanks for any help

You should *not* define classes inside PythonScripts. PythonScripts are 
stricted
and don't provide the full functionality. Either use filesystem based code 
(Zope
Product) or use simple Python datatypes as dictionaries in this case.

An External Method behaves exactly the same. I have not yet involved in 
writting even the simpler Product and i will not do it now for such a 
trivial issue.

I tried to return a dictionary,
-  return {'a':1, 'b':2, 'c':3}  --
but it the DTML Doc fails with a KeyError.
I was wondering if there was some "Zopish" way to do it i don't 
know. i kinda desperate here :-)

Use a dict and if you really need DTML... see the keyword
"mapping" for  and  tags.

If you want to return custom class objects into untrusted
code (e.g. from external methods) you need to set security
declarations on them - at least add the attribute:

__allow_access_to_unprotected_subobjects=1 

(from top of head - just grep -r zopes source
for the actual name)

[Zope] Running different Zope versions

[Henk Laloli]

 
Is it possible to run different Zope versions on one machine?
I have a Zope 2.6.4 running and a Zope 2.7.3 both on a Windows 2003 server. They use their own python. I run them on different port numbers configured in the zope.conf file. Both are installed as services. Yet, when both are started usually only the 2.6.4 is available. I have to turn it off to reach the other. What did I forget? Any suggestion appreciated.

[Zope] Anonymous users can download files stored in a restricted folder

[Barbara Harris]

Is it possible to restrict access to the file download
function by setting permissions on the folder containing a published file?

 

In a Zope 2.6.4 CMF site, running on Apache, I have removed
anonymous access from a portal folder (the restricted folder) and published documents
and files in that folder.  If a document elsewhere on the site contains a
hyper link to a DOCUMENT in the restricted folder, anonymous users are prompted
to login to the site when they select the link – this is what I
want.  However, a hyper link to a FILE published in the restricted folder
triggers the Windows file download window and allows an anonymous user to
download the file.  

 

Without introducing special procedures, I would like to
provide the content owner with the facility to publish files in the restricted
folder, and create hyperlinks to these files throughout the site that can only
be accessed via Zope members.  

 

Initially I restricted the folder by deselecting
‘Acquire permission settings?’ and selecting Manager and Member
roles only on the following permissions:

 

- Access contents information 

- View

 

Subsequently I deselected and reset the roles on all the (restricted
folder’s) permissions allocated to the Anonymous role at Zope instance
and site level, but it made no difference.

 

Tacking ‘view’ onto the end of the file url
works, but this requires additional user intervention and an extra step in the
download, so I’d rather find a once-off permissioning solution if I can
i.e.

 

http://myCMFsite/myRestrictedFolder
(loads the login page – desired result)

http://myCMFsite/myRestrictedFolder/myPublishedDocument
(loads the login page – desired result)

http://myCMFsite/myRestrictedFolder/myPublishedFile
(triggers the Windows file download window – not acceptable)

http://myCMFsite/myRestrictedFolder/myPublishedFile/view
(loads the login page – desired result)

 

The content owners’ platform is IE6 or Firefox1
running on Windows 2000 or XP.

Barbara Harris

Hmmm, could it be that you changes only the HTTP port and that the FTP
port or webDav port still tries to use the same port on both
instances?

Otehrwise I have no idea. It's always worked fine for me, I think. :)

Zope's security model, by design, allows objects to be published even if
the container cannot be;  therefore you need to ensure that the object
itself does not become viewable by anonymous.

You likely need to modify the "Security" tab on the "published" state in
your workflow to prevent granting "View" permission to "Anonymous".  You
probably want it to have the "Acquire?" flag turned on, instead.

[Zope] how to expand a branch using dtml-tree ?

[BonviciniJ]

I would like to know if its possible to expand a specified branch of a 
tree,using the dtml-tree tags.

I use this tag to display the tree of my site:


 
 

But I have a problem.I want the chosen branch to keep expanded when the user 
click on the link.
At the moment, when I click on a branch (expanded or not), the page is called 
buit the tree is initialised (all branches collapsed)

So I wonder if its possible to kepp the branch expanded (by adding a special 
line, or send via post the id of the branch and expand it on the next loading 
of the page).
I add that The tree is in the same page and I don't want to use frames

thanks a lot for your help, and scuse for the english

Please look at the "Security" tab of one of your documents:  I'm willing
to bet that, after publication, the "View" permission is granted to the
Anonymous role.  In that case, the settings on the folder are irrelevant.

To make those settings relevant, you are going to have to change
something:  using a DCWorkflow (there is one available which mimics the
'default_workflow') and tweaking the security settings for the
"published" state is your likeliest bet.

In that case, you would:

 1. Delete the 'default_workflow' from the 'portal_workflow' tool.

 2. Create a DCWorkflow in the tool, selecting the option labelled
"default_workflow (Web-configurable workflow [Classic])".

 3. Change the security settings settngs on the "published" state,
turning on the "acquire" flag for the "View" permisison and turning
off the grant to "Anonymous".

 4. Use the "Update security settings" button on the "Workflows" tab of
the workflow tool to re-apply the settings you have just tweaked.

I've readded the Zope list to the address;  note that, since this is
workflow-related, the zope-cmf list would be a more appropriate forum.

[Zope] Description Strings in Archetypes

[S . D .]

I'm running Archetypes 1.3.2-final in Plone 2.0.5 (Mac OS X Server). I added the
Article example from ArchExamples to the available items list in a Plone site.
It works fine except for the fact that when you look at a list of Articles
inside a given folder, each item's Description is taken from the Description
string of the containing folder rather than the Description attached to that
individual Article.

For example, if I create a folder named "Foo" whose Description field reads
"Place your foo in this folder," that description is attached to each of the
Articles you see when you look at the folder listing.

Apparently, the Description info is being taken from the wrong "Description."
How can I adjust Archetypes to find and display the correct, Article-specific
Description?

Thanks!

Scott

[Zope] Newbie ZPsycopgDA question

[Heather Bumbalough]

I am very new to Zope & Python so please forgive me if this is stupid question 
or if the answer is posted elsewhere (I've looked!)...

I am using Zope v. 2.8.0-a1, Python v.2.3, and psycopg-1.1.18.  After adding 
the ZPsycopgDA connection in Zope the Status indicates I am connected to the 
database but the tables do not show up on the Browse tab and when I attempt to 
perform a query on the Test tab I get the following (from the log):

Traceback (innermost last):
  Module ZPublisher.Publish, line 113, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 40, in call_object
  Module Shared.DC.ZRDB.Connection, line 123, in manage_test
  Module Shared.DC.ZRDB.Results, line 76, in __init__
TypeError: object does not support item assignment

I have tested adding tables and removing them and that works fine, but I have 
to use phpPgAdmin to see them.

Any ideas on what I need to change?

Thanks!

Can you try with 2.8.0a2?  I'm pretty sure that Sidnei da Silva checked
in a fix for that.

[Zope] Session without cookies.

[Fernando Lujan]

Hi everyone,
Is there possible to use a Session control without cookies?
I already changed the browser_id_manager and unchecked the cookies and 
checked the "Automatically Encode Zope-Generated URLs With A Browser Id" 
option. But it's just stops working. :(

In addition, where could I get the Examples? The Zope book has a mention 
of it, but I couldn't find the URL to download the Examples.

Thanks!

[Zope] Composite Objects?

[Jeffrey E. Forcier]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hey all,

I'm attempting to use mostly-vanilla Zope to implement an intranet
here at my office, but am finding it difficult to use a 'feature' that
I imagine should be possible. I've created a template for what ideally
would be a single object/class type, containing multiple different
kinds of Zope objects, and want to be able to clone new copies of that
template as one can do with the existing Zope objects (e.g. as one
would add a new File or Folder).

The template currently consists of a typical index_html ZPT, a
Formulator form, a small collection of Python Scripts, and two generic
Files which are the CSS and JavaScript includes for the ZPT. These are
all contained in a normal Folder object.

The ideal situation is that I want a single object, which has various
data fields (storage location is not important at this time) that are
manipulated with the above objects--the ZPT+files generate a form
page, using Formulator for rendering and validation, and the Python
scripts for various other tasks, including the eventual input
processing. And, as stated before, I need to be able to instantiate
new copies of this object.

Now, I first looked at ZClasses (which according to the Zope Book is
exactly what I want), but it appears that each ZClass instance shares
the 'methods' in the ZClass definition--so that if I wanted each
individual object to add fields to its own Formulator form, it
couldn't. On top of that, I read and (mostly) understand some of the
recent discussions here about possible deprecation of ZClasses, making
it even less of a desirable option.

I then looked at CPSSchema, but what appears to be its homepage on
zope.org cannot be accessed even after one creates an account on the
site; furthermore, what little I was able read about it suggests that
it too is not quite what I'm looking for. Ditto for Plone's ArchTypes
(plus I'd *rather* not have to use Plone, as this intranet is not
really going to be a CMS in the classical sense).

So, I'm pretty much out of ideas; obviously I could just write my own
Product from scratch, and that's what I'll be looking into in the
meantime, but this seems like something that should be possible, and I
hope I'm just missing something or being misled by what I've already
read. Please help :)

Regards,
Jeff

I gather you want to be able to modify the scripts and such
for each copy, which argues against the usual solution of building
a Product.  

You might check out AbracadabraObject, which seems tailor-made
for your use case.

Actually, no--the only thing that would change per-instance would be
the Formulator form and, of course, the underlying data. The logic, as
scripted in the Python Scripts, would be the same for all instances.
In other words, this is just a plain old object-oriented class (data
structures + methods) but one that needs to hold Zope data types.

I'll take a look, thanks.

Re: [Zope] object creation in a specific folder...

hello all,

context.getRestrictedTraverse('/myapp/myfolder'), and then create the

The manage_addProduct method creates an object in the context in which 
is was called. Which is to say, the object it is called on. If you say 
context.manage_addProduct(...) you're creating an object on the current 
object (or the current object's container.)

The restrictedTraverse method gets and returns some object; it does not 
"change folders". (The API note reads: "Return the object obtained by 
traversing the given path from the object on which the method was 
called, performing security checks along the way.") You're thinking 
file-system-wise, and that doesn't work here. Think objects.

(Note: I don't think 'getRestrictedTraverse' exists. 
'restrictedTraverse' on the other hand, definitely does.)

What you want to do, then, is call manage_addProduct on the object 
returned by restrictedTraverse::

  context.restrictedTraverse('/wherever/a').manage_addProduct(...)
Of course, you can also get a certain folder via acquisition::
  context.wherever.a.manager_addProduct(...)
unless you're getting paths dynamically.

[Zope] Newbie questions:

[Enrique Arizón]

Hi again, I'm starting to make up with Zope, but still
basic doubts remains:

Q1: When using normal python I'got used to the
dir(Object) to learn new APIs/Libraries. But when
trainning with my first Zope Scripts I can't. The "dir
not defined" error appears. ???

Q2: I can access the Zope management console and the
help system but when I got to Zope Help -> API
Reference -> "Something" I'm requested for a
user/password. I try with the one I defined during the
initial setup (the same I use to access the Zope
Man.Console) but is rejected. What I did wrong?

 Thanks in advance for any help, hint, link!

You put it in there manually. So it cannot work as you expect.

Being a relative newbie myself, I'm not positive this is correct, but
I can tell you that Python Scripts are limited in Zope--you can't
access the entire set of normal Python libraries and functions. A
large part, yes, but not all of them. I'd be surprised if 'dir' was
not in the allowed functions, but that would be one reason why it's
claiming it's not defined.

In that case, I'd write a filesystem Product for the logic.
Replace the scripts with methods of the Product class.
Make it folderish so it can contain Forumator forms and anything
else you want: inherit from Folder and use its UI to manage
contents.

You could then use AbracadabraObject to clone instances of
this thing; or you could do it all in code and have a manage_afterAdd 
method that adds a preconfigured Formulator form.
Source and/or docs of Formulator should give you a clue how
to instantiate one with the right config.

Mostly correct, except I'd say a "small part" rather than "large part".

That's kind of what I was thinking. AbracadabraObject appears to have a 
method call that allows you to use its magic in code, which I think is 
exactly what I want, although as before I'm very surprised that this 
sort of functionality doesn't exist in Zope proper.

I guess my desires aren't actually all *that* in-line with the main body 
of Zope users, as I do *not* want the users of this application to ever 
see a ZMI screen. So I need this half-and-half situation where I or 
another admin can tweak some aspects of a class (e.g. Formulator forms, 
ZPT) via the ZMI or WebDAV, but the instances of those objects are 
instantiated *via code only*, by Python logic and my own (ZPT-driven) 
HTML form interface.

Another possibly far-fetched feature I'd like, which again I believe was 
part of ZClasses, would be to be able to tweak the instances' Formulator 
forms after the fact...e.g. add another data field a year down the road. 
Of course this then means that I both do and don't want these cloned 
forms to match up with the central one, and I'm not at all sure that I 
can accomplish this without writing lots of my own code to handle it.

Thanks for the help, by the way, it's appreciated.

Well, it's not really all that hard.
Googling ZopeLabs turns up a bunch of potentially relevant recipes.
...although, i cheated and searched for the method names because
I already know what they are :-)

That's not so unusual.. see for example CMF and all its offspring,
e.g.CPS, Plone

to all of 'em? Traditionally we do this sort of thing via an
iterator script. Something like:

all = context.ZopeFind(context, obj_metatypes=['Formulator Form'],
   search_sub = sub)
for form in all:
form.callSomeMethod() # i'm too lazy to look up the formulator API

yep, there's no free lunch with that kind of problem.
