Delayed publishing django. How to implement?

Question

Django

Suppose there is a publication model

class Publication(models.Model):
    '''
    ..............................
    '''
    publish = models.BooleanField(default=False)
    publication_datetime = models.DateTimeField()

You can bind this action to the crown. Let's say python managa.py check_post_publication_command
But are there any ready-made solutions?
