DoesNotExist at /admin/blog/blog/add/: blog matching query does not exist

[Jaap van Wingerde]

Suddenly I can no longer add blogs to Django. Django says 'blog
matching query does not exist'. That seems strange to me because I want
to add something to the database and not request a blog. What could be
going on here?

admin.py:
class blogadmin(admin.ModelAdmin):
def save_model(self, request, obj, form, change):
if not change:
obj.added_by_user = request.user.username
obj.ip_added = request.META['REMOTE_ADDR']
if obj.ip_added == '127.0.0.1':
obj.ip_added = request.META['HTTP_X_FORWARDED_FOR']
obj.publish = False
del obj.publish_date
else:
obj.changed_by_user = request.user.username
obj.ip_changed = request.META['REMOTE_ADDR']
if obj.ip_changed == '127.0.0.1':
obj.ip_changed = request.META['HTTP_X_FORWARDED_FOR']
if obj.publish == True:
if not obj.publish_date:
obj.publish_date = obj.datetime_changed
super(blogadmin,self).save_model(request, obj, form, change)

I can add text, photographs etc., but no blogs, changing is ok.

Notifications:
DoesNotExist at /admin/blog/blog/add/

blog matching query does not exist.

Portainer weird situation

[Marcella Carvalho]

Hi, guys.
I use portainer to manage my docker containers. One of them is my django 
webapp, with a binded mounted volume in my server.

When I recreated the container today with a newer image version, Portainer 
erased my volume. It never happened before.

So, my question is, this has ever happened to you? How did you solve it?

save_model doesn't run on Django version 4

[Mike Kilmer]

After having upgraded from Django 3 to 4 the save_model() method isn't 
running, though the form it imports does.

```
class MyCoolMapAdmin(SuperUserChangeOnlyMixIn, FilterByOwnerAdmin):
form = MyCoolModelForm
print("this prints on app initialization")

def save_model(self, request, obj, form, change):
print("this never runs")

class MyCoolModelForm(forms.ModelForm):

def clean(self):
print("this does run")
```

The `save_model` method doesn't seem to run for new or updated form 
submission from the "MyCool" admin page.

Thank you.

One thing I'm not sure of it, how to tell if a particular Admin page is 
triggering a particular Admin instance.

Yes, Django is an open source framework and you can use it to build your own
