Answer 1

You are trying to specify a database at a file path (which would work for SQLite). MySQL needs a database name (eg 'wogma'). You'll have to follow the instructions to install MySQL, create a new user and database etc. It appears you're on Windows, so I can't help any more than that.

Answer 2

1. open a sql console and type SHOW DATABASES;

2. if wogma appear just put this in your settings (you are using django 1.1):

   DATABASE_ENGINE = 'django.db.backends.mysql'

   DATABASE_NAME = 'wogma'

   DATABASE_HOST = '127.0.0.1'

   DATABASE_PORT = '3306'

3. if not appear just create it in this console CREATE DATABASE wogma ; and make the steps again.

Answer 3

Try with this connection configuration:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'MY_DATABASE_NAME',
        'USER': 'root',
        'PASSWORD': 'MY_PASSWORD',
    }
}

But First , create the database in your mysql.

Answer 4

As directed by above answers , the below code will not work

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'MY_DATABASE_NAME',
        'USER': 'root',
        'PASSWORD': 'MY_PASSWORD',
    }
 }

You would have to download MySQL Connector . Read this post to setup your MySQL database in Django 2.1.x
