i dont know why django can't see my db, maybe you guys have some ideas.
Mysql didn't get me any problems before this case,
i haven't found a way to fix an error, so I counting on your help.
thanks in advance

The shortest answer to that is that django database ist't crated in MySQL. Django will not create the database for you like it do on sqlite3, you have to had this database created before.
You can ensure that you created the database by running a command like that:
$ mysql -h 127.0.0.1 -pmypassword -u myusername # to connect on your mysql
mysql> show databases; # list all databases on your MySQL server
To create a new database my recomendation is the following:
mysql> create database django charset utf8mb4; -- charset is optional
mysql> use django;

Pycharm / Django defer Oracle Database connection

I have a Django project that connects to an Oracle database - implemented in PyCharm. I would like the app to monitor the connection and display a status as to whether the database is up or down. I stopped the listener to simulate an error. However, when I start the PyCharm server to test the functionality, the app immediately attempts a database connection and fails. Is it possible to defer the database connection until I can command one within the app?
Here is the error traceback on server startup:

I just mentioned user model and settings in this question but still if more code is required then tell me I'll update my question with that information. Thank you

I don't know if you have left the port empty for the question or it is actually empty, but try this in the console and see if the connection is successful.
conn=psycopg2.connect(database="rulings", user="xxx", password="xxx",port=5432)
Also this might not be your port(it is the default but yours might be changed) check your port number \conninfo in the postgres shell. And let me know if it helps.

You have to check for the host_ip or the port number in the settings.py file of django.

Access Denied Django : (1045, "Access denied for user 'darth_vader'#'151.33.241.48' (using password: YES)")

I am using django 3.0 and using MySQL database for my web application.
My settings.py code is:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'thirdihrms',
'USERNAME': 'admin',
'PASSWORD': 'xxxxxxxx',
'HOST': 'database-1.xxxxxxxxx.us-east-1.rds.amazonaws.com',
'PORT': '3306',
}
}
And instead of connecting to the admin#151.33.241.48 it's getting connected to the darth_vader username.
The darth_vader name is my ubantu machine (Local development environment) home user name.
I see "darth_vader#Rushikesh-HP:~$ " when i open my terminal.
The error message:

So is there any config change or setting change so i can run my application.

The key to specify the username is 'USER' [Django-doc], not 'USERNAME'. As the documentation specifies:
USER
Default: '' (Empty string)
The username to use when connecting to the database. Not used with
SQLite.
You thus should fix this with:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'thirdihrms',
'USER': 'admin', # no USERNAME
'PASSWORD': 'xxxxxxxx',
'HOST': 'database-1.xxxxxxxxx.us-east-1.rds.amazonaws.com',
'PORT': '3306',
}
}

Handling sensitive keys django

OS: Win 8.1
System: surface pro 3
python 2.7.9
postgre: 9.3
django 1.7.1
I am trying to complete the Ultimate Django tutorial: https://ultimatedjango.com/learn-django/lessons/handling-sensitive-keys/?trim=yes
On the section of sensitive keys it gives me the following errors when I run the server with : python manage.py runserver
CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.
Then on the settings.py i put :
ALLOWED_HOSTS = ['*']
and when I run the server again gives the following error:
Performing system checks...
System check identified no issues (0 silenced).
