I have trouble when I execute the command python migrate.py migrate.
I'm learning a little about django, and I need synchronize django with a mysql database.
In settings.py file, I put the right database, username and root password, I don't know why is not having access for root.
So here's my error:
(Ambientepython3) leonardo.oliveira#dss-skinner:~/django-tutorials/mysite$ python manage.py migrate

Does anyone knows what to do, please?
try it it will definitely helps you
run the command in your Cpanel Hosting Terminal
pip3 install mysql-connector-python==8.0.29
First I have migrate and makemigrations and then I have dump data with this command:
python manage.py dumpdata --exclude auth.permission --exclude contenttypes > dvvv.json
I have tried to flush the database but when I execute python manage.py loaddata dvvv.json the following error occurs:

django.db.utils.OperationalError: (2013, 'Lost connection to MySQL server at \'reading initial communication packet\', system error: 2 "No such file or directory"')
I did some searching on StackOverflow:
Error during Django "Running migrations": django.db.utils.OperationalError: (2013, 'Lost connection to MySQL server during query')
Trouble closing and reopening MySQL connection after catching/handling django.db.utils.OperationalError (2013, Lost connection to server)
but it was not very helpfully
further digging on the subject lead to me believe that MYSQL database is denying the access to my Django app.
I could try this theory as I don't access to MYSQL setting at all
To summarzie; I need migrate on django app but I had error running the command.
Help, please, I really appracite if you could help me with this.
I'm new to coding. Maybe you make a beginner mistake?
mismatch of the word? Include, cap underline?
I don't know if I was helping.
Just suggesting
This could cause by MYSQL DB having a time.
you correct this by going into the MySQL Workbench and set long DMSB.
Here the link on article responding to this error:
https://anothercoffee.net/fix-error-code-2013-lost-connection-mysql-server-query/
The mysql official document on this issue;
https://dev.mysql.com/doc/refman/5.7/en/error-lost-connection.html
Hope this help
