I am having an error when using django to use the Mysql connection to either a local or remote database. Initial error that i had when i tried to install mysqlclient were resolved when in installed using brew mysqlserver and client. I can connect to the local db through command line but when i use the connection through django i get this error.

```auto

I found a workaround for this problem.  
[How to use PyMySQL with Django - Adam Johnson](https://adamj.eu/tech/2020/02/04/how-to-use-pymysql-with-django/)

used pymysql to connect to the mysqldb.

By the way you can also try mariadb if you intend to use docker with it.
