Hi,
The field 'continent' in Location model is redundant, should not be there.
class Location(models.Model):
continent = models.ForeignKey(Continent,on_delete=models.CASCADE)
country = models.ForeignKey(Country,on_delete=models.CASCADE)
city = models.CharField(max_length=50)
street = models.CharField(max_length=100)
