Can I make the foreign key field optional in Django model

Question

I have this code

subject      = models.ForeignKey(subjects)
location     = models.ForeignKey(location)
publisher    =  models.ForeignKey(publisher)


        

Answer 1

Sure, just add blank=True, null=True for each field that you want to remain optional like

subject = models.ForeignKey(subjects, blank=True, null=True)
