在創(chuàng)建外鍵的時(shí)候遇到報(bào)錯(cuò)：
TypeError: __init__() missing 1 required positional argument: 'on_delete'
查詢(xún)一番后發(fā)現(xiàn)Django2.0版本創(chuàng)建外鍵時(shí)需要在后面加上on_delete
class Car(models.Model):
manufacturer = models.ForeignKey(
'Manufacturer',
on_delete=models.CASCADE,
)
#...```
添加后問(wèn)題解決
