django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')

Question

My model:

class Course(models.Model):
    language = models.ForeignKey(Language)
    name = models.CharField(max_length=50, unique=True, default=\'course\')
         


        

Answer 1

I ended up adding

'OPTIONS': { 'init_command': 'SET storage_engine=INNODB;' }

to my DB backed configuration in settings.py and that fixed the problem.

The MySQL server was configured to use InnoDB as a default engine, but due to some reason it still tried to create tables with the MyISAM. I am running MySQL 5.1 with Django 2.2.1 and Python 3.6.7
