I deleted my postgresql database from pgAdmin III (right click on databases/mydatabase => delete/drop).
Now I want start anew and make the first migration that should create the database but instead it give an error: database don't exist.
Until now I was using sqlite3 and this procedure worked.
What I should do?

First migration doesn't create the database, it needs existing database to create tables in it.
To create postgres database run from your terminal:
createdb -U postgres possedimenti_database
You might have to replace postgres in above command with your database user.
check the details in your settings.py for your DB. Recreate the PostgreSQL database using those exact same details (port number, user, host, password etc). Try this existing solution here link here:
PostgreSQL - create a new DB through pgAdmin UI in order to create the DB via pgAdmin

django.db.utils.OperationalError
I modified only this base.py part, but the "migrate" command is not executed and an error occurs. What is the reason?
installed postgresql
create DB name as "instagram"
installed cookiecutter
modified "base.py"
run "py manage.py makemigrations"
error occured
Now I'm using postgresql version 15, could it be the reason of error?
Because I tried to use version 14 also but have same error.
Remove all the migration files, then:
python manage.py makemigrations
python manage.py migrate
EDIT 1
have added _test.py with postgresql database connexion data but failed when I run I run the command py manage.py test cafe.tests.CafeTestCase --settings=core.settings._test
RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the first PostgreSQL database instead.

django.db.utils.OperationalError
I have a Django app set with Docker and different developpement environment: dev, preprod, prod.
I use a postgresql database / pgaadmin 4 in my local Windows environment
I want to write and run tests 'outside' Docker in a VSCode terminal
(because if I use web container to run tests, changes in my tests.py are not updated so I need to down, build and re-run my containers)
so I run the command py manage.py test cafe.tests.CafeTestCase --settings=core.settings.preprod where I speficy the settings to consider
But I got an error sqlite3.OperationalError: no such function: Now because some data migrations use timezone.now() that i not available in sqlite
but I have specify test_database in my settings and given access to user so test should consider postgresql no?
_test.py
DATABASES = {
'default': {
"ENGINE": "django.db.backends.postgresql",
"NAME": "db_preprod",
"USER": "user_preprod",
"PASSWORD": "user_preprod",
"HOST": "localhost",
"PORT": "5433",
'TEST' : {
'NAME': 'test_db_preprod',
}
}
}
so you just have to create the database (or use an existing database) in your _test.py settings
Since SQLite does not provide the now() function, you need to to replace now() by datetime('now')
I've been looking everywhere but cannot seem to find anyone with my same problem. Here's my situation...
Django App: Running on Centos7 Vagrant guest 10.0.0.2 connecting to DB
Postgresql-10 DB: Running on Centos7 Vagrant guest 10.0.0.1 serving the Django app, also has pgAdmin4 running on it
When I bring these vagrant machines up they are able to initially connect. I notice when I leave them idle for periods of time then the Django app cannot connect any longer to the DB. Even weirder, most of the time, but not all the time, I simply needed to restart the postgresql database service and it would be able to connect again. Right now that's not even the case so I can no longer ignore this problem by just restarting the DB service.
Any ideas on what could be going on here? I've tried a couple things but nothing seems to work. My feeling is it's something on the database machine causing issues since like I said usually this just required a simple restart of the DB service to fix.
I'm completely confused by how it just loses connection sometimes randomly.
Below is the error that is printed out when I try to restart the django app and run "python3 manage.py makemigrations"

Now this may be something very foolish to do, but please allow me to discuss my issue. I am attempting to have Django access a database on a remote device by accessing it's network directory like so (in the settings.py script):
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': '/run/user/1004/gvfs/sftp\:host\=169.254.131.151\,user\=root/root/injection_log2.sqlite',
}}
I've successfully created a file, viewed a file, and edited a file through Vim and that exact directory. So doing this should work right? But I am getting the following bug:

So in conclusion I have a few questions! Is what I am doing possible? If so, what am I doing wrong? If not, is there some good alternative? Thanks! Also I'm working on Ubuntu if that helps!
