[Zope3-Users] problem with adding a catalog

[Zope3-Users] fighting with Pluggable Authentication Utility
Now I have a problem with the Pluggable Authentication Utility.
(win32/Zope3/trunk/30009)
I have a folder(hu03), which a made a Site.
In the default Site-Management Folder I created a Pluggable
Authentication Utility (pauloc).
Which has a SessionCredentialsPlugin (s2), a PrincipalFolder
(usrloc) and a HTTP Basic-Auth Plugin (http2).
There is one user in the PrincipalFolder (jani).
For Credentials Plugins http2 and s2 is selected.
For Authenticator Plugins usrloc is selected.
Every plugin is active.
Just for fun with
(http://localhost:8080/hu03/++etc++site/default/pauloc/usrloc/@@grant.html)
I granted _every_ role and permission to jani, including Site Manager,
Site Member, ...
Now jani is able to login, but objects requiring zope.ManageContent
permission just return "Unathorized".
There is a method,
zope.app.securitypolicy.zopepolicy.settingsForObject which I tried to
use to check permissions with. But it returns:
hu03
{'principalPermissions': [], 'rolePermissions': [], 'principalRoles': []}
{'principalPermissions': [], 'rolePermissions': [], 'principalRoles': []}
global settings
{'principalPermissions': [], 'rolePermissions': [{'setting': PermissionSetting:
Allow, 'role': 'bugtracker.User', 'permission': 'bugtracker.AddBug'},
{'setting': PermissionSetting: Allow, 'role': 'zope.Manager', 'permission':
'bugtracker.AddBug'}, {'setting': PermissionSetting: Allow, 'role':
'zope.Manager', 'permission':
...
I guess that means that jani does not have the roles/permissions.
Please help

[Zope3-Users] How to resolve bi-directionally navigable association?
As the subject sais, how can I resolve bi-directionally navigable association in Z3? Both objects have to have references of each other, that means that also the schemas have to have references. class IItem(interface): unit = Object( title=u"Unit", description=u"Unit", required = False, schema=IUnit) class IUnit(interface): item = Object( title=u"Item", description=u"Item", required = False, schema=IItem) but obviously that does not work, I cannot define one before the other. The only way I found is defining a dummy interface before the other: class IUnit(interface): pass class IItem(interface): unit = Object( title=u"Unit", description=u"Unit", required = False, schema=IUnit) class IUnit(interface): item = Object( title=u"Item", description=u"Item", required = False, schema=IItem) Is there any better solution? -- Best regards, Adam mailto:[EMAIL PROTECTED] ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

[Zope3-Users] schema constraint sets required?
I'd like to check a field if it is a valid e-mail address.
It can be also empty.
The first trial was:
class ISzemely(Interface):
...
email = TextLine(
title=u"Email cim",
description=u"Email cim",
constraint=re.compile("(^[\w\W]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]{2,3}$)|(^$)").match
)
...
The second was:
EMAIL_REGEX =
re.compile("(^[\w\W]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]{2,3}$)|(^$)")
def emailcheck(value):
if value is None:
return True
return EMAIL_REGEX.match(value)
class ISzemely(Interface):
...
email = TextLine(
title=u"Email cim",
description=u"Email cim",
constraint=emailcheck
)
...
If I do not fill in a value in the browser "Required input is
missing." message comes.
At the second version the execution even does not reach "emailcheck".
How to solve that?

Re[2]: [Zope3-Users] Debugger for Zope 3
Hi, If we are coming to commercial IDEs then Komodo is also a good choice for debugging. You just have to put it's dbgp module on the PYTHONPATH and use the below small script to avoid some irritating deprecation mesages. After this, you put brk() in you code and it will stop there. After it was stopped for the first with brk() the debugger will obey all 'normal' breakpoints. I think it supports threading also but never tried it. import zope.deprecation from dbgp.client import brk as dbgpbrk def brk(): zope.deprecation.__show__.off() dbgpbrk() Wednesday, April 26, 2006, 9:58:52 AM, you wrote: > On Tuesday 25 April 2006 08:27, Achim Domma wrote: >> I would like to start Zope 3 with the debugger, set some breakpoints in >> my modules and step through the code to learn more about Zope. > WingIDE's debugger is superb.

[Zope3-Users] Re: [Zope3-dev] Community opinion about workflow engine
Hello Godefroid, I'm having a bit biased view, because I know just zope.wfmc and have the luck developing a pure Z3 application. I think with zope.wfmc you have - WFMC/XPDL support, you can shine with standards and big companies love standards - because it's XPDL support there's a graphical process editor jpEd - the core itself is quite sophisticated, but still misses some things for complete WFMC coverage (the WFMC spec is rather huge) - you can/should add some layers on top of it: - z3c.wfmcpersistent to store the processes in ZODB - ecm.workflow to have a higher level of APIs and functions (That was written by Roger Ineichen, but as nuxeo moved to jboss it was not maintained by them. Therefore I intend to move that code to z3c.wfmc, when I have some time to breathe. I have some improvements to the code. We even have plans to implement time management or scheduling with the package) All in all we're quite comfortable with zope.wfmc in our project.

Re[2]: [Zope3-Users] correct display of Text field in a view
Hello Ivan,
I don't think that you'll need IMultiLineText and MultiLineText.
That's why IText and Text are there for. You'll have to register the
widget for IText or use it directly in your view with
CustomWidgetFactory.
In fact it's a good question why Z3 doesn't provide such a widget for
Text. The current widget is just Displaywidget which eats the
newlines.
BTW: "" should be ""

[Zope3-Users] Community opinion about search+filter
Hello, I'd like to ask your opinion, your experiences about searching and filtering in quite large object DBs. We need to add search and filter functions to our current app, where the user might be able to create quite _sophisticated_ filter criterias. (The app is a pure Z3 app, subject is document management) Currently we're looking at something based on catalog/indexes. As I checked the most comfortable solution would be based on hurry.query. Some questions arose: - Is it necessary/worth adding indexes on all attributes? - How does the index perform on modification and retrieval? The biggest problem is that this will be our first try, so we're missing experiences and are a bit puzzled about the right solution. Certain is that moving to RDB is not an option.

Hello!
I'm trying to implement a DropdownWidget for my country list. In my app i'd like to have a dropdown menu where a user can choose a country (for my main content object, a job). My vocabulary is created from a list of strings, and stored in a local utility:
SimpleVocabulary.fromValues( [u'AD', u'AE', 'AF', ...] )
But in my dropdown widget i want to display the country name for each option too.. and not just the same value on both the value attribute and inside the element:
Andorra
So i send in a different vocabulary.. one that looks like this:
[(u'AD', u'Andorra'),...]
So i coded this:
-
class CountryDropDown(DropdownWidget):
def __init__(self, field, request):
#This returns a dict: {'countrycode':'countryname'}
territories = request.locale.displayNames.territories
# Invert the territories dict: keys=names, values=ccodes
self.territories = sorted(territories.items (), key=itemgetter(1))
#not using this any longer..
#voc = getUtility(IVocabularyFactory, u'Country codes')
voc = SimpleVocabulary.fromItems(self.territories)
super(CountryDropDown, self).__init__(field, voc, request)
def textForValue(self, term):
return term.value
-
But it seems like when i choose a country, e.g Andorra, the constraint fails. I think it is because my modified vocabulary that i sent in which it is now checking constraints against fails.
I want the constraints to be checked in my ordinary vocabulary but i want to use a different one when populating the dropdown.. any ideas?

Re: [Zope3-Users] Zope3 packages inside a standalone application
Hello Marco, I would say it won't hurt if you flatten the namespace. You might also try to add all required packages to the PYTHONPATH then hopefully py2exe will find them.

[Zope3-Users] bsquare'ing
Hello,
I'm trying to setup a buildbot here for our buildout based packages.
What I don't get is, how that works:
f.addStep(Compile(name='bootstrap',
command='buildout bootstrap .',
description=['bootstrapping'],
descriptionDone=['bootstrap']))
We used to issue "python2.4 bootstrap.py",
"buildout bootstrap ." gives an error, unless I'm missing something.
Also, I'd propose some enhancements too:
-def configure(svn_url, http_port=8010, allowForce=False):
+def configure(svn_url, svnuser=None, svnpasswd=None,
http_port=8010,allowForce=False, poller=None):
"""Creates a buildout master configuration.
The configuration returned is almost functional. You just need to add
slaves.
"""
c = {}
c['slavePortnum'] = 8989
-c['change_source'] = SVNPoller(svn_url, split_file=split_file,
pollinterval=30)
+if poller:
+ c['change_source'] = poller
+else:
+ c['change_source'] = SVNPoller(svn_url, svnuser=svnsuer,
svnpasswd=svnpasswd, split_file=split_file, pollinterval=30)

== Zope 3.4.1 Released! == June 22, 2010 - The Zope 3 development team announces the Zope 3.4.1 release. The 3.4.1 is the long awaited next bugfix version of 3.4.0. Major changes ~ - setuptools update to 0.6c11, so that it supports svn 1.6. - z3c.layer update to 0.2.4, which is a **SECURITY** fix. For details see the changelog. Packages and Eggs - Zope 3 is now fully converted to an egg-based system. While some work still remains, it integrates very well with the rest of the Python community. The conversion to egg-based packaging also enables other Python developers to only have to use small bits and pieces of the complete Zope software system. The conversion means that Zope 3 developers do not use the classic Zope 3 tar-ball release anymore. However, for your convenience, Zope 3 developers will provide the classic Zope 3 tar ball releases for at least the 3.4 series. So how are Zope 3 applications built using only eggs? The Known Good Set (KGS) The known good set -- or in short KGS -- is a configuration of packages and their versions that are known to work well together. The compatibility is frequently verified by running over twelve thousand tests on a daily basis [1]_. The KGS is tested against Python 2.4 and 2.5 on the 32- and 64-bit platforms. The list of controlled packages and their versions for Zope 3.4 can be found at the Zope 3 KGS site [2]_. The KGS can be used in several ways [3]_. The most common way is to "nail" the versions by downloading the version configuration file [4]_ and insert them as follows in your buildout configuration:: [buildout] versions = versions ... [versions] zope.interface = 3.4.0 ... ``zopeproject`` Project Builder ~~~ To start building a project using a common setup, a package called `zopeproject` can be used to quickly setup the boilerplate for the project. Ample documentation is provided at the `zopeproject` home page [5]_. `zopeproject` uses Paste or ZDaemon to create a working server. The following commands get you started:: $ easy_install zopeproject $ zopeproject HelloWorld $ cd HelloWorld $ bin/helloworld-ctl foreground Demo Packages ~ At this point, there is no demo package demonstrating a simple Zope 3 application setup. However, the ``z3c.formdemo`` package can be used as a fairly minimal setup. To get started with it, enter the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.3 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v $ ./bin/demo fg ..

Installation instructions for both Windows and Un*x/Linux are now available in the top level `README.txt` file of the distribution. The binary installer is recommended for Windows. Zope 3.4 requires Python 2.4 or 2.5 to run. You must also have zlib installed on your system.

It was rewritten from scratch based on the latest software design patterns and the experiences of Zope 2. The component architecture is the very core of Zope 3 that allows developers to create flexible and powerful web applications. Compatibility with Zope 2 ~ Zope 3 is not upwards compatible with Zope 2. This means you cannot run Zope 2 applications in Zope 3. We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2 use more and more of the Zope 3 infrastructure. This means that new code written in Zope 2 can benefit from Zope 3 technology. Also, with care, code can be written that works in both Zope 3 and Zope 2. This allows a Zope 2 application to slowly evolve towards Zope 3. Unchanged Zope 2 applications are never expected to work in Zope 3, however. About the Zope Foundation - Th

You might be interested in z3c.json, z3c.jsonrpc.
Especially z3c.jsonrpc, that should handle such requests with ease.

Re: [Zope3-Users] Accessing raw post data
Hello Edoardo,
I think the simplest would be to make the upload a
multipart/form-data, with some headers added if you can.
Worst case putting the necessary text manually around the binary?
Then it's a usual POST request what's easily parsed by zope.
Otherwise it could be really nasty.
