当 django 模型与此逻辑勺中同一模型的另一个字段 link 时,无法编辑布尔字段?
can't edit Boolean field on django model when it is link with another field from the same model within this logic scoop?
我正在开发 django v4.*,我遇到了一个问题,我需要在 is_published is ticked
时自动填充字段 publish_date
import datetime
class Article(models.Model):
.......
is_published = models.BooleanField(default=False)
publish_date = models.DateTimeField(blank=True, null=True)
.......
def save(self, *args, **kwargs):
if self.is_published:
self.publish_date = datetime.datetime.now()
super().save(*args, **kwargs)
这成功了,但问题是我无法再编辑 is_published
字段,
当我勾选它(使其为真)时,即使我尝试将其更改为取消勾选,它也保持为真
您的保存操作现在是您的 if: 语句的一部分。将其降低一个缩进级别,以便它始终结束函数
