Django ContentTypes提供了一个GenericInlineFormSet,但是the documentation没有解释如何使用它,除了this test,它没有以我理解的方式真正解释它。
请你能帮我理解吗?
假设我有以下课程
class Dog(models.Model):
name = models.CharField(max_length=64)
breed = models.CharField(blank=True, max_length=64)
class Meta:
verbose_name = 'Dog'
class Fish(models.Model):
name = models.CharField(max_length=64)
habitat = models.CharField(blank=True, max_length=64)
class Meta:
verbose_name = 'Fish'
class Pet(models.Model):
content_type = models.ForeignKey(
ContentType,
limit_choices_to={'model__in':('dog', 'fish')},
verbose_name='Species'
)
object_id = models.CharField(max_length=64, verbose_name='Animal')
object = generic.GenericForeignKey('content_type', 'object_id')
owner = models.ForeignKey(Owner)
class Meta:
unique_together = [("content_type", "object_id")]
显示宠物表单的视图是什么样的?
