can't edit Boolean field on django model when it is link with another field from the same model-CodePudding

I am working on django v4.* and I came cross a point where I need to make field publish_date to be auto populated when is_published is ticked

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)

this did the trick but the problem that I can not edit the is_published field anymore, when I tick it (make it true) it stay true even if I try to change it to untick

CodePudding user response：

Your save action is now part of your if: statement. Drop it down an indent level so that it always ends the function

 def save(self, *args, **kwargs):
    if self.is_published:
       self.publish_date = datetime.datetime.now()
    super().save(*args, **kwargs)
