Hi there,
I've got a few global constants that I'd like to be available to my
application and a .zcml file seems to be a sensible place. I'm thinking
of something like a .zcml file with, e.g.:
applicationSettings
setting name=name1 value=value1/
setting name=name2 value=value2/
...
/applicationSettings
This would then be available in a component as a dictionary. Is anythign
like this already available ?
You could just use utility, and thereby group your constants into
logical chunks.
interfaces.py:
class IDatabaseLoginOptions(Interface):
username = Attribute()
password = Attribute()
config.py:
class DatabaseLoginOptions(object):
implements(IDatabaseLoginOptions)
username = 'foo'
password = 'bar'
configure.zcml:
utility factory=.config.DatabaseLoginOptions /
used:
opts = getUtility(IDatabaseLoginOptions)
Obviously, this is a bit more work than just declaring some constants in
ZCML, but global constants suffer the same problems whether they're
defined in Python or XML. Parts of your application are making
assumptions that they are there, with very specific names, which are not
type checked.
