按照 Django 教程，“python manage.py migrate”不会创建任何 Django 表（MySQL、Pycharm）

Question

In mysite.settings.py I have:

   DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': os.path.join(BASE_DIR, 'test'),
        #'NAME': 'test',
        'USER': 'root',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '3306',
    }}

When I run 'python manage.py migrate' in the PyCharm terminal, nothing happens, no error message etc. No new tables are created in the database specified. I tried two things for NAME as you can see.

MySQL Server version 8.0.19 MySQL Connector/Python 8.0.19 Python version 3.8 In PyCharm I have package mysqlclient 1.4.6 installed.

Any advice on how to find the problem? How to get an error message?

Thank you

DATABASES property specifies your DB configurations. Now NAME is the property which specifies your database name.

Currently here 'NAME': os.path.join(BASE_DIR, 'test'), won't work as it will give you something like C:/YourUser/YourPath... so this string is not a valid db name. basically (os.path.join() returns a path to your project directory)

First create a db manually on MySql, note the name and put it in property as 'Name': DBNAME in SETTINGS.py .

(Make sure you have your environment set while running following commands) Then try python manage.py makemigrations for checking migration changes, if everything goes fine up till here then fire python manage.py migrate command.
