Re: [Zope3-Users] Containers Contains
This I know, so that is exactly my question. What is the preferred approach in Zope? The contains and containers, or the more explicit methods?

I use formlib and when I'm defining the Forms I always omit the implicit fields '__parent__' and '__name__'. If you're using addforms in ZCML you have to use the attribute option to specify all your field but the ones above. HTH. Regards, Douglas.

Re: [Zope3-Users] Containers Contains
Here is an example that gives me the IInputWidget errors when I use
the contains/containers approach:
...interfaces.py...
class ICRM(IContainer):
"""Just a blank container to hold customers."""
contains('.ICustomer')
class ICustomer(IContainer,IContained):
"""A basic customer."""
contains('.IService')
containers(ICRM)
salesperson = Choice(
title = _(u'Sales Person'),
description = _(u'The sales person responsible for this
account.'),
vocabulary = "Sales Person",
required=True)
supportperson = Choice(
title = _(u'Support Person'),
description = _(u'The support person responsible for this
account.'),
vocabulary = "Support Person",
required=True)
class IService(IContained):
"""A service provided by the company."""
containers(ICustomer)
approveddate = Date(
title=_(u"Approved Date(-MM-DD)"),
description=_(u"The date this service was approved by
finance."),
required=False)
...
class CRM(BTreeContainer):
"""Just a blank container to hold customers."""
implements(interfaces.ICRM)
class Customer(BTreeContainer):
implements(interfaces.ICustomer)
salesperson = u''
supportperson = u''
class Service(BTreeContainer):
implements(interfaces.IService)
approveddate = u''
...

contains() and containers() is a newer and prettier way to achieve the
same result. It didn't exist when Stephan's book was written.
I have been having some problems and would be curious the definitive
approach. The former is more complicated and so I find make lots of
coding errors. The latter is simple but I find it causes strange
IInputWidget errors.
Could you show us some code?
