我在Django中有两个常规模型:
class One(models.Model):
title = models.CharField('title', max_length=255, blank=True, null=True)
class Two(models.Model):
first_field = models.ForeignKey(One)
ones = models.ManyToManyField(CouponType, related_name='ones_two')
我想动态地做这样的事情:
item_one = One()
item = Two()
item.ones.add(item_one)
适用于外键:
field = Two._meta.get_field('first_field')
kwargs = {field_name: value}
field_value = field.rel.model.objects.get_or_create(**kwargs)[0]
setattr(Two, 'first_field', field_value)
如何为ManyToMany字段执行相同操作?
答案 0 :(得分:0)
如果您要考虑如何将数据添加到多对多列表
your_object.ones.add(what_you_want_to_add)
