i don't have time to work on this project at the moment,
if anybody wants to maintain and develop z3ext i'll give access to svn.

right now z3ext trunk works with ztk

Zope3 checkObject vs z3ext checkObject

mcarlos@linux.vnet.ibm.com (Cadu Moreira) — Mon, 29 Mar 2010 22:57:56 GMT

Hi guys,

      We are trying to specify a customized precondition, which should validate a contenttype before it is added.
      According to the Zope3 documentation, we should proceed as presented below (copy/paste from zope.app.container.constraints.py from zope.app.container-3.5.6-py2.5-linux-i686.egg):

   >>> def preNoZ(container, name, ob):
   ...     "Silly precondition example"
   ...     if name.startswith("Z"):
   ...         raise zope.interface.Invalid("Names can not start with Z")

   >>> class I1(zope.interface.Interface):
   ...     def __setitem__(name, on):
   ...         "Add an item"
   ...     __setitem__.precondition = preNoZ

   >>> from zope.app.container.interfaces import IContainer
   >>> class C1(object):
   ...     zope.interface.implements(I1, IContainer)
   ...     def __repr__(self):
   ...         return 'C1'

However z3ext seems to overwrite checkObject, implementing its own method, which is located in: z3ext.content.type.constraints.py inside z3ext.content.type.-1.1.0-py2.5.egg.

My question is: Is there a way to add my own validation (for instance, as presented in Zope3 piece of code, above) as precondition, to the z3ext validation?

                          Thanks and regards
Carlos Moreira

Sorry, my bad, it worked, somehow. I think it was releated to setuptools-0.6c9. If you still get the above error, or the following one:

raise VersionConflict(dist,req) # XXX add more info

VersionConflict: (setuptools 0.6c9 (.../virtualz3ext/lib/python2.5/site-packages/setuptools-0.6c9-py2.5.egg), Requirement.parse('setuptools==0.6c11'))

Do:

easy_install setuptools==0.6c11

providing my own content actions and category

gustavorahal@gmail.com (Gustavo Rahal) — Tue, 26 Jan 2010 04:13:51 GMT

I want to provide my own actions for a certain container content type. Default actions portlet behavior is to show contained types like this:

Add content
    Add foobar
    Add foobar2

I was able to add an extra section to actions portlet like this:

Phases
    Add foobar
    Add foobar2

The problem is that I cannot disable the "Add content" category and it's actions ( thus leaving "Phases" category and it's custom actions)

So, I could not find a way to do this with current support so I figure out that something like this might make sense

1. Mark content type with interface "INoAddContentAction" (or something like that)
2. in "class AddContentActions(ContentAction)" - content.actions.contentactions.py (152) do something like:

        for ct in self.contenttype.listContainedTypes():
            if not INoAddContentAction.providedBy(ct):
                weight = weight + 1
                yield AddContent(context, request, ct, weight)

make plain view model default for content

gustavorahal@gmail.com (Gustavo Rahal) — Mon, 25 Jan 2010 19:40:01 GMT

I'm creating some contents that don't need to bother about document view models tab but wanted to make the plain view model the default. How do I do that?
Do I need to mark content with z3ext.content.models.document.plain.interfaces.IPlainModel? If that is the case, where?
thanks

gustavorahal@gmail.com (Gustavo Rahal) — Thu, 14 Jan 2010 19:36:16 GMT

The important pieces of code follow:

class RequirementsStep(WizardStepForm):
    interface.implements(ISaveable)

I'm having a bit of a problem getting started with z3ext. Installing it using buildout is easy, but how to proceed from there? Is there some kind of "design overview" and maybe a list detailing the use of the included functionality? Maybe some best practices or notes for Plone refugees?

gustavorahal@gmail.com (Gustavo Rahal) — Thu, 14 Jan 2010 14:07:54 GMT

I had this same question some time ago... I guess this mean that some UI shortcut might be needed. What you need to do is go to "edit documents" and in the "Contents" tab you can see the contents available. Then you can use the cut or copy btns.

If with the suggestions above you can pass buildout ok but get a failure on missing zope.app.securitypolicy when running ./bin/zopectl then you also need to add zope.app.securitypolicy to setup.py and run buildout again.

Installation flow

Hi,

I'm trying to install z3ext, but kept on failing with package version dependency hell (related to zope.location, zope.site, zope.lifecycleevent - and other packages that depends on them )

if i understood correctly, the process should be:

install z3extproject
use z3extproject to create a buildout
run buildout
start instance

am I'm doing it right ? .. or did i missed something?

additional info

i'm using python2.4 on a linux system. z3extproject was installed into a buildout ..

thanks

i didn't like design of z3ext.principal.groups, i suggest just develop authenticator plugin for new code. and if you will do this create branch in package svn
