[Zope-CMF] Re: How-To: Automatically Add Objects at CMF Member Creation Time

[Norman Khine]

Hi Greg,
I looked into both sources and tried to make this work both ways, first:
I modified the CMFDefault/MembershipTool.py, by replacing, the original
entry for the creation of the index_html with:-

# Create index_html: open and read 'index_html.dtml' from 'Products/dtml'
  fileobj = open(os.path.join(product_path, 'dtml', 'index_html.dtml'), 'r')
  filedata = fileobj.read()
  fileobj.close()

  # Create Member's home page.
  # default_member_content ought to be configurable per
  # instance of MembershipTool.
  Document.addDocument( f
                      , 'index_html'
                      , member_id+"'s Home"
                      , member_id+"'s front page"
                      , "structured-text"
                      , (filedata % id)
                      )
  # give the image the correct portal type
  ob = f._getOb( 'org_logo' )
  if hasattr(ob, '_setPortalTypeName'):
      ob._setPortalTypeName('Document')
  # Overcome an apparent catalog bug.
  f.index_html.reindexObject()


but got an error on restarting the server

2001-08-21T01:13:12 ERROR(200) ZODB Couldn't load state for
'\x00\x00\x00\x00\x00\x00|B'

SystemError: Failed to import class _ZClass_for_DefaultDublinCoreImpl from

9 times

So, reinstalling the original MemebrshipTool.py and adding the file creation
to the CMFDefaultHotfix __init__.py, which is listed below.

Thinking this will overide the existing index_html creation and pull in the
file I have created in the CMFDefaultHotfix/dtml/index_html.dtml

but it does not, this brings the original index_html file created by the
MembershipTool.py, what am I doing wrong?

my index_html.dtml file is in CMFDefaultHotfix/dtml/ directory and
newtons.gif is in CMFDefaultHotfix/img/ directory

index_html.dtml

        <h1>Congratulations %s!</h1>
        <p>You've successfully joined blabla ...</p>
        <img src="pic.gif" />

Thanks
Norman
