A, Django2.2 connect to the database (step on mine)
First, Django2.2 comes with a sqlite3 database, but we learned about mysql, therefore learn to connect ( in the environment to build mysql case of success ) --- Reference blog:
https://blog.csdn.net/qq_20788055/article/details/80372577
1.1 mysql data into the control bar (because mysql password is required, can not directly create)
mysql-uroot-p password (my presence here so show could not be created) - Creating a database
Then fill out the appropriate application user and password --- according to library just created in order to pycharm
1.2 to perform database migration command makemigrations
python manage.py makemigrations
Will complain that there is no mysql client - but I have, so import package
pip install pymysql ( in fact there are many similar packages, but pymysql ---- support python2, python3 ------ can also masquerade as a client mysql )
1.3 migration is performed again, and the error ---- panic, version compatibility issues
1.4 python change profile ******* \ Lib \ site-packages \ django \ db \ backends \ mysql \ base.py file and
lib\site-packages\django\db\backends\mysql\operations.py文件
-------base.py
----- originally changed to encode to decode ----
1.5 and then perform the migration --------- success, mysql and own client database software sync
