django-3.0

问题 I have been read some Django document about inheritance models and parent_link . Suppose that I have these models: class Parent(models.Model): #Some field goes here! class Child(Parent): #Some field goes here! I have 3 questions about this pattern: What should I do if I want to create new child object and pass id of existing parent to that? What should I do if I want to create just new child object and after a while create parent object for that child? Also I din't understand this document
