remove Subcategory model and write Category model like this

class Category(models.Model):
    categoryName=models.CharField(max_length=100)
    parent = models.ForeignKey("Category", null=True, blank=True)

    def __unicode__(self):
         return self.categoryName

and remove subcategory field from Product. Writing like this is more neat

What you are looking is a reverse relationship, to do that you use models.ForeignKey('self', on_delete=models.CASCADE). The official doc is here https://docs.djangoproject.com/en/1.10/ref/models/fields/#foreignkey

I hope it helps Best
