I feel like I know enough to squeak by, but that's no longer
acceptable. Sometimes I quiver in terror, waiting for everything to
fall down because of something so seemingly basic like strings/text.
It may be a lot of technical debt, or it may be extremely easy to pay
down. In any case, it's time to pay it down. :)
In addition to what has already been said (and maybe not really
what you are asking for), the number one problem people encounter
can be illustrated within a simple interactive Python session
like this one:
[EMAIL PROTECTED] ~]$ python244
Python 2.4.4 (#1, Jan 29 2007, 13:00:46)
[GCC 4.1.1 20060525 (Red Hat 4.1.1-1)] on linux2

s1 = uI'm unicode
s2 = I'm a byte string
s1 + s2
uI'm unicodeI'm a byte string
s1 = uI'm unicode äöü
s1
uI'm unicode \xe4\xf6\xfc
s2 = I'm a byte string äöü
s2
I'm a byte string \xc3\xa4\xc3\xb6\xc3\xbc
s1 + s2
Traceback (most recent call last):
File stdin, line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 18:
ordinal not in range(128)
s1 + s2.decode('utf-8')
uI'm unicode \xe4\xf6\xfcI'm a byte string \xe4\xf6\xfc
It's Python's implicit casting of byte strings to unicode strings
the moment it has to deal with both together with Python's default
encoding being 'ascii' (don't ask why - it's been a long discussion
at the time ...).
The moment you get the strings involved from some application
call or third-party code you often don't really know what you
will get, so unless you do extensive checks and explicit
decoding using the right codec you'll never be on the safe side.
Within Zope 3, however, this should be a non-issue as Zope 3
(including Zope 3-based applications) should only use unicode
strings.
Just my 2 cents.

[Zope3-Users] Default value for an interface attribute
Hi everybody. I have this interface: class INews(IPage): A news page for the application. date = Date( title=_(uPublication Date), description=_(uThe intended date for this news), default=date.today(), required=False ) My problem is that I started the instance on February 21, and when I use an AddForm for this interface, my form shows that date instead of today's date, which is what I need. It seems like the default attribute is set once upon server start and then never changed. Is that the case? If it is, could you please point me to a better approach for this? Thanks.

Hi friends!
Hmm... strange thing...
With this code I got:
browser = Browser('http://localhost:8080/')
browser.addHeader('Authorization', 'Basic admin:admin')
browser.open('http://localhost:8080/manage')
Traceback (most recent call last):

urllib2.HTTPError: HTTP Error 500: Internal Server Error
Add
browser.handleErrors = False
to see the real exception, not just an HTTP 500.
Above exception is the same, as with browser.handleErrors = False
Totaly confused here, is the above method is *right* to access ZMI?
What is *right* way to access ZMI via zope.testbrowser?
Thanks!

This authorization is not correct. You need to use:
manager.addHeader('Authorization', 'Basic mgr:mgrpw')
At least this is the default.

I think it is not nice solution so I'd love to see better way of doing this. How about checking whether the value of 'default' is a callable and if so call it to obtain the default value. That way defautl=date.today (without the ())should do what Douglas expects (maybe this is even the case already?). Not that you want to know this but in Archetypes we explicitly support 'default' and 'default_method' as field properties. If no 'default' is provided, 'default_method' is looked up and if it exists it's called. Raphael ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

I tried this way, but raises this Exception:

This is an unsupported use case. I bet if someone writes up a proposal and brings it up to discussion on zope3-dev@zope.org we'll find a common solution to this. Please also notice that we're moving to using launchpad more heavily. So if you write a proposal in the wiki, please also submit it as a feature request (blue print) in launchpad for the Zope 3 product.

In most Zope 3 ftest layers it is. I believe he's on Zope2, though.
I think his problem is that he's using the Zope 3 test browser in Zope
2. He should be using Products.Five.testbrowser.Browser.
