Greetings
Have anyone got postgres with high availability setup to work with django ?
If yes can you please share any resources on how to do the right configuration?
Thanks

Hey James,
Just to add to what was already said there's a ticket tracking the addition
of
database level foreign constraints.[0]

Indeed! I have actually used the admin site to do it before I posted this
it's just something I didn't know was by design. After numerous searches I
came here but I may have been asking the wrong questions in google :).
The shell would be good if I have quite a few I need to delete. Thankfully
If you search about it on the Internet many sources claim that Django
does not set those constraints on the database level.
If you look at the code of the base code for database backends, you'll
notice that they don't mention on_delete at all. - https://github.com/d
jango/django/blob/6dd4edb1b4f54
well, nothing stopping you from doing the same in the django shell and
doing `Group.objects.get(pk = some_pk).delete`. that would be an
alternative for going straight to the db.
I can see some issues with this coming up, especially if you're doing
deletes with django's raw sql capability. But
OK. So it's by design.
So during development I can't go straight to the database and delete a
"Group" quickly due to an error I made. I'd have to set up tests to deal
with it at an application level.
No probs though. I'm just happy I know it can't be done and not that it's a
bug I'd have to wa

Not quite. If you run python manage.py sqlmigrate
, you can see the SQL generated for that migration.
https://docs.djangoproject.com/en/2.0/ref/django-admin/#django-admin-sqlmigrate
Because Django emulates Cascade, its done outside of the db, and therefore
shouldn't be a db-level constraint.
OK, understood. However, If you set up CASCADE on the model surely when it
creates the table on the database level it surely should set ON DELETE
CASCADE not ON DELETE NO ACTION on the CONSTRAINT?

I'm having a little trouble with my "through" table. I've set the modal to
have two Foreign Key fields. Ex. below:

title = models.CharField(max_length=255)

Hi all,

It is fine since I'm keeping an events table which may have several creation

Hi,
Actually, there is a confusion between the administrative data django fills and
the data the admin application owns itself.
Unless I'm mistaken, Django admin application only creates 1 table I named in
my previous message (django_admin_log).
Can you check this table has been created ?
If it
Apologies I should have been more clear,
'It' refers to my domain name when visited "/admin"

Also, what kind of users are you speaking about ? system, database or django
users ?
Do you have the admin site available in the urls ? Did you uncomment both the
url and the auto discovering part ?
Did syncdb showed django_admin_log table being created (or can you check it has
been created) ?
