How code the relationship like
"a person has many friends"
code so far.
class Person(models.Model):
full_name = models.CharField(maxlength=100)
nick_name = models.CharField(maxlength=20)
about = models.TextField(blank=True)
sex = models.CharField(maxlength=1, choices=SEXES)
# contact is also a person object so it is a reference to same
person
# more study needs to be done on how to add attributes to
ManyToMany relationship in Django
# e.g. we may need to define whether a contact is my friend etc.
# creating a separate class for Contact may not be the a good
solution, since a Contact is also a Person
contacts = models.ManyToManyField('self')
Or like this
class PersonRelation(models.Model):
person = models.ForeignKey(Person)
relations = models.ManyToManyField(Person, related_name =
'friends')
type = models.IntegerField(choices=FRIEND_TYPES)
group = models.IntegerField(choices=GROUP_TYPES)
please highlight pros and cons.
