How do I create and query models in Django?

In Django, you create models by defining a class that inherits from models.Model. Each class attribute represents a database field.

Can you show 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=100)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

How do I query this model to get all posts?

You can query all posts using Post.objects.all(). This will return a queryset of all Post instances.

What if I want to filter posts by title?

You can filter posts by title using Post.objects.filter(title='Your Title'). This will return posts that match the title.
