Actually, I found a way to do it but it's quite ugly and I guess it will be
easily broken
by any Django updates:
<code>
from django.utils.encoding import smart_unicode
class CustomLogEntryManager(models.Manager):
def log_action(self, user_id, content_type_id, object_id, object_repr,
action_flag, change_message='',
change_comment=''):
e = self.model(None, None, user_id, content_type_id,
smart_unicode(object_id),
object_repr[:200], action_flag, change_message, change_comment)
e.save()
from django.contrib.admin.models import LogEntry
LogEntry.add_to_class('change_comment', models.CharField(max_length=255,
blank=True))
LogEntry.add_to_class('objects', CustomLogEntryManager())
</code>
Then I just override any admin methods that use LogEntry.log_action(...) to
also pass a change_comment
parameter.
Can anyone think of a better way to do this?
Btw, I'am using 1.0.2 at the moment. Would v1.1 offer anything that would
make this more easy to implement?
I'm grateful for any hints, design tips, etc.
Thanks,
tom.
