Django 使用多对多字段
示例
我们从第一个示例使用此模型：
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)将汤姆和比尔添加到夜总会：
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)
谁在俱乐部？
for person in nightclub.members.all():
print(person.name)会给你
Tom Bill
