AttributeError: 'DatabaseWrapper' object has no attribute 'is_mariadb'

When i am running the makemigration command for this model

from __future__ import unicode_literals

from django.db import models
from django_mysql.models import JSONField

class Owners(models.Model):
    name = models.CharField(max_length=255)
    url = models.CharField(max_length=128, null=True, blank=True)
    email = models.EmailField(null=True, blank=True)
    phone = models.CharField(max_length=32, null=True, blank=True)
    address = models.CharField(max_length=128, null=True, blank=True)
    country = models.CharField(max_length=32, null=True, blank=True)
    description = models.TextField(null=True, blank=True)

class Brands(models.Model):
    name = models.CharField(max_length=255)
    owner = models.ForeignKey(Owners, null=True, blank=True)
    url = models.CharField(max_length=128, null=True, blank=True)
    description = models.TextField(null=True, blank=True)
    tags = JSONField(null=True, blank=True)

    (conn.is_mariadb or conn.mysql_version < (5, 7))

I suspect you don’t have django_mysql in your INSTALLED_APPS, as previously reported and will be fixed in #323 .
