In unittests the ZCML-Directives are not used so you have to do the
things from ZCML in your test-code before adaption.
from zope.interface import classImplements
from zope.app.testing import ztapi
classImplements(str, IString)
ztapi.provideAdapter(IString, IHTTPConnection, HTTPConnection)

Neither one appears to work in a Zope2 trunk checkout.
Am I doing something wrong?
In lib/python/Products/StandardCacheManagers, I have:
# configure.zcml ###
http://namespaces.zope.org/zope";>
interfaces.py ###
from zope.interface import Interface, Attribute
class IHTTPConnection(Interface):
"""Represents an HTTP connection.
"""
def request(method, path):
"""Send an HTTP request.
"""
def getresponse():
"""Get a list of strings representing a response.
"""
class IString(Interface):
"""Dummy interface to let me adapt strings
"""
# XXX what should be in this?
# toward the end of
# tests/testtests/test_AcceleratedHTTPCacheManager.py #
def test_XXXinterface(self):
url = 'http://www.google.com'
from Products.StandardCacheManagers.interfaces import IHTTPConnection
conn = IHTTPConnection(url)
#
This raises an error, regardless of whether I remove the registration of
IString or not:

Re: [Zope3-Users] Adapting a builtin?
It is valid both to:
- Declare an interface for a built-in type and
register adapters for that interface, and to
- Register adapters for builtin types directly.
I can't promise that this works now, but it ought to work.
I'm 90% sure that it does in fact work, at least in Zope 3.

Something like:
Hi,
in plain Zope3 (I'm not using Five, but it may be similar there.) you
can declare an interface for the buitin: (e.g. in interfaces.py)
class interface IStr(Interface):

def upper():
"upper ... as an example"
In configure.zcml, you declare the interface for the builtin:
Then you can do:
IHTTPConnection('string') to get the adapter.

That's a interesting question. I do it also, but in a different
way. It works for me like this and the adapter registry and
persistence work well.

[Zope3-Users] Adapting a builtin?
Hi, Is it possible to register an adapter for a builtin type such as str? All the adapter examples I see use an interface for the "for" attribute. Something like: This doesn't seem to work, although it doesn't give any errors. I'm using five in a Zope 2 trunk sandbox. Later I'll dig through it with pdb and see what I can find out, but meanwhile I hoped somebody here had already solved this problem... -- Paul Winkler http://www.slinkp.com ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
