Hi, list,
I am just trying to migrate a existing application from Zope2 to
Zope3, and had to feel around for my ways to do things correctly.
I have following view.pt snippet:

Hi, everyone,
This must be novice question:
Is there a package providing relational database based authentication
service for zope 3 already lying around somewhere or do I have write
one?
And how does one connect a login form with the authentication service?
In Zope 2 one can have lots products

Hi, everyone
In the book "Web Component Development with Zope 3", it is mentioned
that one can use the URL adapter ++debug++tal to show the tal tags
besides the rendered page, provided the devmod is turned on.
But how is this working exactly? For I can not see the URL adapter
taking any effects.

authenticated, what role or permission does she/he get?

I thought this would be a simple case for Zope3, but after one whole

Hi,
Does there exists for Zope3 a content component for creating/editing
HTML pages through the Web, preferably with the ability to upload
images related to the HTML document? Something similiar to ATDocument
for Plone/Zope2?

How do I dynamically generate javascript and css files and how to register them?

The z3c.json write implementation uses str to convert any unrecognized
data types json. But json only recogonizes basic data types, and
strings must be enclosed in quotation marks, so the data
representation given by z3c.json is often invalid. For example:

Tyring out z3c.extfile, I added in zope.conf file the following
product configuration section:

This doesn't not work as expected when I am using Paste and wsgi.
Looking into the code, I think the config function in zope.app.wsgi
should be patched by adding:

One caveat, I you are using product-config directive to specify your
application directory, please note that it can not be retrieved by
zope.app.appsetup.getProductConfig if you are using zope.app.wsgi to

In stead, a patch to zope.app.wsgi is needed. See my mail 2 day

Hello,
With z3c.extfile, if the path name of the HashDir utility is a unicode
string, as configured by the directive in zcml, a unicode
digest will be returned. However, loading the file with this digest
raises a ValueError, since the getPath function only recognizes
StringType as digest:

Hi,
If I find the current translation in zope.app.locales not
satisfactory, how can I submit an update?
In particular, I find a bug in the Chinese (zh_CN) translation which
causes the sizes of content objects not displayed in the rotterdam
skin. Following is the fix, hope someone can commit it.
When I use z3c.jsonrpc (svn head) to publish an object, the response
generated gets the content header:

According to the README.txt of the package:
This project provides the proposed request type "application/json". The request

No, it is regretful that ExtJS (at least 2.0.1 which I am using)
doesn't function well with z3c.jsonrpc out of the box, because
