Here's an idea that's a bit cleaner, thanks to the newforms-admin branch...
In that branch, the Admin options class has a new hook,
formfield_for_dbfield(). This takes a database Field instance and
returns the newforms Field instance, so you can use it to implement
admin-specific editable stuff:
def formfield_for_dbfield(self, db_field, **kwargs):
if db_field.name == 'my_uneditable_field':
return None # No form field
return super(MyAdminClass,
self).formfield_for_dbfield(db_field, **kwargs)
The remaining question, then, is whether form_for_model should *not*
create formfields for database fields with editable=False. Judging by
people's comments in this thread, it seems like that's a no-brainer --
if editable=False, then the form_for_model form should not include the
field.
If there aren't any other thoughts on this, let's go ahead and update
the ticket using our slick new triage process. :-)
