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

Hi, 

I am creating a model, which is taking a description as text field. when I migrate I see the below error:

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

ON further research I came to know that its some limitation with MySQL. I am using MYSQL for my dev. Below is the link that describes the issue.

MySQL error: key specification without a key length

MySQL error: key specification without a key length I have a table with a primary key that is a varchar(255). Some cases have arisen where 255 characters isn't enou...

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)
