Well, it's gotten worse.
I've been trying to narrow this down, and so far, haven't come up with
anything promising. I'm now using the built in principal folder, and
the associated principals, not ones of my own. My current failing test
case boils down to:
interfaces.py
============
from zope.interface import Interface
from zope.schema import TextLine
from zope.app.annotation.interfaces import IAnnotatable
class ISomeContent(Interface):
text_content = TextLine(
title = u"Text Content",
description = u"Some Text Content for testing")
class ISomeContentAttributable(IAnnotatable):
"""An object that can contain some content"""
configure.zcml
===============
<configure xmlns="http://namespaces.zope.org/zope";
xmlns:browser="http://namespaces.zope.org/browser";>
<content class="zope.app.file.file.File">
<implements
interface="zope.app.annotation.interfaces.IAttributeAnnotatable
.interfaces.ISomeContentAttributable"
/>
</content>
<adapter
for=".interfaces.ISomeContentAttributable"
provides=".interfaces.ISomeContent"
factory=".somecontent.SomeContent"
trusted="true"
/>
<content class=".somecontent.SomeContent">
<require
permission="myproject.View"
interface=".interfaces.ISomeContent"
/>
<require
permission="zope.View"
set_schema=".interfaces.ISomeContent"
/>
</content>
<browser:editform
for=".interfaces.ISomeContentAttributable"
schema=".interfaces.ISomeContent"
label="Some Content"
name="content.html"
menu="zmi_views" title="Some Content"
permission="zope.View"
/>
</configure>
somecontent.py
=================
from zope.interface import implements
from interfaces import ISomeContent
KEY = "somecontent.perm_tests"
class SomeContent(object):
implements(ISomeContent)
text_content = u"apple"
def __init__(self, context):
self.context = context
So there's the code, if I change myproject.View to zope.View,
everything works. I can grant myproject.View on the object itself, to
the appropriate principal, and I will get an Unauthorized error. Yet
if I change it to zope.View, it works.
Any ideas?
Thanks,
