How do I create models in Django?

How do I create models in Django?

To create models in Django, you define a class in your app's models.py file that inherits from models.Model.

Can you give me an example of a simple model?

Sure! Here's a simple model for a blog post:

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

What do I need to do after creating a model?

After creating a model, you need to run python manage.py makemigrations and then python manage.py migrate to apply the changes to the database.

How can I add fields to an existing model?

You can add fields by modifying the model class and then running makemigrations and migrate again to update the database.
