Django link mysql

We need to create a good library in advance

1 to go to the configuration file configuration-related parameters

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'day50',
        'HOST': '127.0.0.1',
        'PORT': 3306,
        'USER': 'root',
        'PASSWORD': '123123',
        'CHARSET': 'utf8'
    }
}

2 configuration item name or application name following __init__.py

import pymysql
pymysql.install_as_MySQLdb()

Database migration command

python manage.py makemigrations

Just change your records to the database migrations folder inside

python manage.py migrate

It is really synchronized to the database
