For section C of this exam, consider the following Django models that are part of a web app to collate and display UK election results for the site www.ukelectionresults.com:

class Election(models.Model):
   date = models.DateField()
class Constituency(models.Model):
   name = models.CharField(max_length=128)
   eligible_voter_population = models.IntegerField(default=0)

class ElectionCandidate(models.Model):
   name = models.CharField(max_length=128)
   votes = models.IntegerField(default=0)
   constituency = models.ForeignKey(Constituency, on_delete=models.CASCADE)
   election = models.ForeignKey(Election, on_delete=models.CASCADE)

What recommendation could you make that would be good development practice for the Constituency model?
