FAQs on Django Tutorial 6 Creating Models Video Lecture - Django: The Ultimate Beginners Guide (in Hindi) - Back-End Programming
| 1. What is Django and why is it used for back-end programming? |  |
Ans. Django is a high-level Python web framework that is used for back-end programming. It provides a structured and efficient way to build web applications by following the model-view-controller (MVC) architectural pattern. Django handles many common tasks, such as URL routing, database management, and form handling, allowing developers to focus on writing the application's business logic.
| 2. How do I create a model in Django? | |
Ans. To create a model in Django, you need to define a class that inherits from the `django.db.models.Model` class. Each attribute of the class represents a database field, and the class itself represents a database table. You can define various types of fields, such as CharField, IntegerField, and DateTimeField, with additional parameters to specify their characteristics. Once the model is defined, you can use Django's migration system to create the corresponding database table.
| 3. What is the purpose of migrations in Django? | |
Ans. Migrations in Django are a way to manage changes to your models and database schema over time. They allow you to create, modify, and delete database tables and fields without manually writing SQL queries or affecting the existing data. Migrations track the changes made to your models and generate the necessary SQL commands to apply those changes to the database. This ensures that the database schema remains synchronized with the models defined in your Django project.
| 4. How can I query data from the database using Django models? | |
Ans. Django provides a powerful and flexible Object-Relational Mapping (ORM) system that allows you to query data from the database using Python code instead of writing raw SQL queries. You can use the model's manager, accessed through the model's class, to perform queries. The manager provides methods like `all()`, `filter()`, and `get()` to retrieve data based on specific criteria. You can also use methods like `exclude()` and `order_by()` to further refine your queries.
| 5. Can I use Django models with different database systems? | |
Ans. Yes, Django models are designed to be database-agnostic, which means you can use them with different database systems, such as MySQL, PostgreSQL, SQLite, and Oracle. Django's ORM abstracts the underlying database operations, allowing you to work with the models in a consistent manner regardless of the database backend. You can configure the database settings in Django's settings file to connect to the desired database system, and Django will handle the necessary database-specific operations transparently.
