Django models are the backbone of database interaction in Django-based applications. They define the structure of your data and provide an API for querying and managing the data in your database. Here's a breakdown of key concepts:
📌 Core Concepts
Model Definition
Models are Python classes that inherit fromdjango.db.models.Model
. Each attribute of the class represents a database field.Fields & Data Types
Use built-in fields likeCharField
,IntegerField
, orDateField
to specify data types.Database Operations
Leverage ORM (Object-Relational Mapping) to perform CRUD operations without writing raw SQL.
🛠️ Practical Examples
- Define a simple model:
from django.db import models
class Book(models.Model):
title = models.CharField(max_length=100)
author = models.ForeignKey('Author', on_delete=models.CASCADE)
published_date = models.DateField()
- Query data using
filter()
orget()
methods. - Use
ManyToManyField
for complex relationships.
📝 Best Practices
- Keep models clean and focused on data structure
- Use
Meta
class for ordering and table names - Follow Django's official documentation for advanced features
