Django Cannot Connect to Remote MySQL Server

I am running a Django and attempting to connect to a MySQL server at my university.
First of all:
In order to connect the database, I normally SSH into a remote server (with authentication) of theirs, and then run MySQL and enter my MySQL authentications.
This works without an issue, in Terminal as well as DataGrip.
Now, using PyCharm, I have installed mysqlclient in the intepreter and changed my
settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': '[DB_NAME]',
'USER': '[DB_USERNAME]',
'PASSWORD': '[DB_PASSWORD]',
'HOST': '[REMOTE SERVER ADDRESS HOSTING MYSQL]',
'PORT': '3306',
}
}
Also using PyCharm, I have even opened up a data source in the Data Sources Tool Window and connected through SSH tunnel and MySQL authentication to the database. This is successful, and it is possible to make queries.
However, I try to run:
manage.py check
and I receive:

It is also important to note that I HAVE connected a Django project to this exact same server and database before in a test run. Now, that test project and the new project does NOT connect.
Any help would be appreciated!

Create a Django Database

This code works on other people's local computer - we aren't running it in production yet. But mine isn't working. A coworker indicated that I need to create a database. Prior to using mysql, I was using sqlite, which didn't require this.
When I run python manage.py runserver this is what I get:
XX-MacBook-Pro:xx xx$ python manage.py runserver

django.db.utils.OperationalError: (1049, "Unknown database 'testdb'")
My settings file has this:
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
...
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'testdb',
'USER': ‘xx’,
'PASSWORD': ‘xx’,
'HOST': 'localhost'
}
}
I've tested the user, password and know that they work. My MySQL is fully functional.
If I remove the DATABASES 'NAME' I get:
django.db.utils.OperationalError: (1046, 'No database selected')

Presumably you have tested the username and password by going into the mysql shell. So you can just do the same thing again, and from there do CREATE DATABASE testdb.

Not able to run 'python manage.py migrate'

I am new to programming and learning the web development. I have installed:
-Django 1.9
-postgresql 9.5
-psycopg2(using whl file) db api for the postgresql on Windows 7 os.
not a virtual environment.
I have set up the database connection in my settings.py file for my project as following.
DATABASES = {

'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Test',
'User': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',

}
}
but when I am running migrate I am running in to following problem. I want to connect the postgres to my django

I have checked with python script the psycopg2 is able to connect the database in postgresql but when I am running migrate from django project, its not working and getting above error.

Your database config:

'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Test',
'User': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',
'PORT': '5432',

'NAME': 'Test',
'USER': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',
'PORT': '5432',

}
Notice that User should be USER

Django mysql database credentials read_default_file giving error

I am providing mySql credentials from a different conf file to django project.
Earlier it was working fine, but now it stopped working after I reinstalled my ubuntu.

django.db.utils.OperationalError: (1045, "Access denied for user 'rajiv'#'localhost' (using password: NO)")
Not able to figure out why is it giving error.
If anything is wrong, can anyone suggest some other methods of doing it.

Well if you still want's to use options read_default_file
Then Solution is
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': os.path.join(BASE_DIR, 'connection.cnf'),
}
}
}
connection.cnf
[client]
database = test
user = root
password = rajiv#123
default-character-set = utf8
https://code.djangoproject.com/ticket/24653

Try setting the permission of the config file to 644
chmod 644 connection.cnf
The problem is that because the permissions are too open, the file is ignored, and therefore you are not logged in into mysql.

I faced the same problem and it was pointing to the wrong path.
Try printing the path to the terminal
print(os.path.join(BASE_DIR, ''))
And then correct the path to point to the file

Adding double quotes to the password string worked for me.
