Re: editable=False and manipulator.save(data) not working together

[David S .]

I have also had problems with editable=False.
See http://code.djangoproject.com/ticket/611

But in this case I do not think that you want that anyhow.  
You can use the fields argument when you create your admin 
object to only show what you want as in:

class META:
  admin = meta.Admin(
    fields = (None, {'fields': \
             ('address', 'prefix', 'description',
              'maintainer', 'customer', 'changed_by',)
             })
  )

You can set create_by in the _post_save method add it to the data dict as you
are doing now.

Best,
