I am migrating my django webapp from sqlite to mysql on the pythonanywhere platform and I keep getting the following error:
django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')
I tried several things including the answer here but couldn't make it work. Any suggestions?
My models.py file is very simple:
from django.db import models
class Showww(models.Model):
name = models.IntegerField()
and the full error message is:
Operations to perform:
