[英]How to make one field dependable of another field in models? Django
How to make one field dependable on another? 如何使一个字段依赖于另一个字段? for example
例如
class Example(models.Model):
question = models.BooleanField()
then if question is True: 那么如果问题为真:
example1 = models.ForeignKey('Object1')
when false: 如果为假:
example2 = models.ForeignKey('Object2')
or something like that? 或类似的东西? Thanks for help.
感谢帮助。
My suggestion would be to use a Generic Foreign Key which allows for polymorphic types. 我的建议是使用允许多态类型的通用外键 。 This avoids the extra column.
这样可以避免多余的列。
