Re: reg: Error:-django.db.utils.OperationalError: (1170, "BLOB/TEXT column 'Description' used in key specification without a key length")

This can be resolved using max_length attribute. If it doesn't work try deleting the migration files and doing makemigrations and migrate again.

Hi,

So what am I suppose to use if not TextField? I have tried CharField, that doesn't work either. Below is the model details:

class OnlineShop(models.Model):
    Product_name = models.CharField(max_length=100, unique=True)
    Price = models.IntegerField()
    Slug = models.SlugField(max_length=250, unique=True)
    Description = models.TextField()
    Curr_Time = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return '{}'.format(self.Product_name)
