I'm sorry, I don't think the title of my question is comprehensible as I'm absolutely a noob trying to understand django after LPTHW. Anyway, I'm following a tutorial in setting up Django to use MariaDB. But unfortunately when I run python manage.py migrate I get humongous block of error message. Here's the block:
System check identified some issues:
WARNINGS:
?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default'
HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/2.1/ref/databases/#mysql-sql-mode

I searched a lot but all soloutions were about permissions or auth, not my own models.
I used signals to make a profile for each user on creation,
solved this problem with addign not raw to my signals:

if created and not raw:
Profile.objects.create(user=instance)

I'm using the following modules and MySQL version:
Django 2.1.5
mysqlclient 1.3.14
MySQl 5.1.7.3 Community edition
Anyone that can help me out?
I've found and solved the problem. The table I'm referencing to (allmodusers) was still using the MyISAM database engine. I've changed the database engine of this table to InnoDB after reading the following article: https://kinsta.com/knowledgebase/convert-myisam-to-innodb/.
I have a new server just installed. Everything seems to be fine but when i run:
python manage.py syncdb
it generates follow error:

All the tables and fields, in fact, created automatically without observable problem. I just wanna get rid of this error becoz the same thing does not happen in my old server with exactly the same project running on it.
So I am answering it here so that other people can have answer of same problem:
As said by Bill Kary:
He have solved this himself. Change all the collation of ALL tables AND fields to utf (utf8_general_ci) stops the error beautifully.

Did you run syncdb after adding the app (I'm guessing the app is named sphinx) to your settings.py?
