Sorry, accidentally pressed "send"
ok, where was I...?
class SomeModel(models.Model):
name = models.CharField(bla bla bla)
#Don't let them edit log_entries in admin
log_entries = models.ManyToManyField(LogEntry, editable=False)
#have a field where they can edit their change.
current_log_entry = models.CharField(blablabla)
def __save__(self):
#take input from current_log_entry, make a new LogEntry
with it
#Then clear current_log_entry so next time they edit it,
they have a blank one
#add a relationship to the LogEntry in log_entries
#call save()
class LogEntry(models.Model):
comment = models.TextField()
pub_date = models.DateField()
Something like that might work, though it's a bit of a hack.
