使用 ManyToMany 欄位
我們從第一個例子中使用這個模型:
class Person(models.Model):
name = models.CharField(max_length=50)
description = models.TextField()
class Club(models.Model):
name = models.CharField(max_length=50)
members = models.ManyToManyField(Person)
將 Tom 和 Bill 新增到夜總會:
tom = Person.objects.create(name="Tom", description="A nice guy")
bill = Person.objects.create(name="Bill", description="Good dancer")
nightclub = Club.objects.create(name="The Saturday Night Club")
nightclub.members.add(tom, bill)
誰在俱樂部?
for person in nightclub.members.all():
print(person.name)
會給你
Tom
Bill
