I want to redirect with HttpResponseRedirect or stop and display a
error message in admin view,
when user change some record in admin view while it not means some
conditions.
I try to rewrite save() in models.py
class Seed(models.Model):
....
def save(self):
if os.path.exist(file_a):
super(Seed, self).save()
...
then do redirect view.py,
def seed_pre_save_handler(sender, **kwargs):
...
if os.path.exist(file_a):
return HttpResponseRedirect('/error/')
but above code doesn't work.
I couldn't find a good idea to do redirect from django official
documentation.
