I never fully understood how to use (and extend) forms generated by ZCML addform/editform directives. As I understand you must create custom browser classes, True. and page templates. That is not necessary. Then you must register those with a page or view ZCML browser directive, each of which is more complicated than the addform. The initial complexity may be a little higher, but you get a flexible solution that scales well when you need to change something. Form directives may work well for trivial cases, but they don't scale when you need to change things.

Re: [Zope3-Users] Error when calling addform
Many people have offered approaches. I find the simplest and
cleanest approach for declaring interfaces is as follows:
class IContactList(IContainer):
contains('.IContact')
class IContact(Interface):
...schema fields...
class IContactContained(IContained):
containers(IContactList)
Basically, the schema used in your addform CANNOT include IContained.

You have
containers(IBlogEntry)
in your schema. That's equivalent to
__parent__ = Field(constraint=ContainerTypesConstraint(IBlogEntry))
Your add form is trying to find a widget suitable for Field, but there
isn't one.
Note also that you will inherit
__name__ = TextLine(...)
from IContained. I do not think you want __name__ and __parent__ in
your add form. To skip those fields you'll have to explicitly enumerate
all the other fields:
addform
...
schema=..interfaces.IBlogComment
fields=name email content
...
/
Alternative solution: split the schema into a separate interface,
specify it in the addform directive, then define an interface for your
content object that inherits IContained, your schema, and specifies the
container constraint. It's probably not worth bothering, given that you
need to enumerate only three fields.
An even better solution: learn zope.formlib and use it. Much better
than the bare standard forms. Here's a very short example of an add
form with zope.formlib: http://mg.pov.lt/blog/formlib-adding
I'll copy a part of it here:
class FruitAdd(form.AddForm):
form_fields = form.Fields(IFruit)
Now if you want to omit some fields from the schema, like in your
example above, you can do
class BlogCommentAdd(form.AddForm):
form_fields = form.Fields(IBlogComment).omit('__name__',
'__parent__')
