Consider a university college. 1. College has name, uid, website 2. Each college has a many departments - Each department has name, uid. 3. Each batch in a department has name, and ratings.
*from django.db import models* * * *class College(models.Model):* * name = models.CharField(max_length=200)* * uid = models.CharField(max_length=10, primary_key=True)* * website = models.URLField()* * * * def __unicode__(self):* * return self.name* * * *class Department(models.Model):* * name = models.CharField(max_length=200)* * uid = models.CharField(max_length=10)* * college = models.ForeignKey(College)* * * * def __unicode__(self):* * return self.name* * * *class Batch(models.Model):* * name = models.IntegerField(max_length=100)* * department = models.ForeignKey(Department)* * college = models.ForeignKey(College)* * rating = models.IntegerField(default=0)* * * * def __unicode__(self):* * return self.name* * * Would you suggest any better design ?
