Question

I am having trouble understanding inheritance in django models

If I create a model in django:

from django.db import models
class Person(models.Model):
    name = models.CharField(max_length=200)

Can’t I just I write

class Person(Model):

Since I already imported models and I am trying to inherit Model. Is Model a subclass of models? Also can I write the below, since I have imported models already.

    name = CharField(max_length=200)

This isn’t a Django question; it’s a Python question.

If you’re not familiar with the Python way of doing things, please read up on it before working in Django.

Investigate Python’s module and import concepts to learn about this. A good place to start is the Modules document in the Python tutorial.

The point is that from django.db import models imports the models module, so that you have a variable in that scope named models which is the models module.

It is possible to have something like from django.db.models import Model, CharField, but for Django models the convention is to import the models module, rather than its components.
