[Zope3-Users] No module named formlib...

[Joshua Burvill]

Hello All,

I am starting to work through Benji Yorks zope3 quickstart document which I
am enjoying, but I've run into one problem.

http://www.benjiyork.com/quick_start/

When I do the steps to create the edit form for hello world, I can no longer
start zope. See below for the traceback.

Any help appreciated.

It seems the problem is with the line

from zope.formlib import form

In hello.py

When I try at the interactive python prompt I get:

>>> from zope.formlib import form
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in ?
    from zope.formlib import form
ImportError: No module named formlib

hello.py:

import persistent
from zope import interface, schema
from zope.formlib import form

class IHelloWorld(interface.Interface):
    greeting = schema.TextLine()
    subject = schema.TextLine()

class HelloWorld (persistent.Persistent):
    interface.implements(IHelloWorld)
    greeting = 'Hello'
    subject = 'world'

class MessageView(object):
    
    def message(self):
        return '%s %s!' % (self.context.greeting, self.context.subject)
 

class EditView(form.EditForm):
    form_fields = form.Fields(IHelloWorld)



I am using precompiled python 2.3 on windows xp, precompiled zope3
3.1.0final for python2.3.
