1
What is Django and why is it popular?
Django is a Python-based web framework that helps developers build websites quickly and securely. It is popular because it includes many built-in features such as authentication, admin panel, ORM, and URL routing, which save time and reduce the need to write everything from scratch.
2
How is Django different from Flask?
Django is a full-stack framework that comes with built-in tools like an admin panel, ORM, and authentication system. Flask is a micro-framework that is lightweight and flexible, but developers have to add most features manually. Use Django for large projects, and Flask for smaller, lightweight apps.
3
What is the difference between a Django project and an app?
A Django project is the complete setup that contains all settings and configurations for your site. An app is a smaller module inside the project that handles one specific feature, such as blog, accounts, or shop. A project can have multiple apps working together.
4
What is the MVT architecture in Django?
MVT stands for Model-View-Template. Models handle the database, Views contain the business logic, and Templates are used to design the user interface. Django follows MVT to keep code clean and separate responsibilities.
5
How do you start a new Django project?
You can create a new project by running the command `django-admin startproject projectname`. This will generate files and folders needed to start working on your project.
6
How do you create a new app in Django?
Inside your project folder, run the command `python manage.py startapp appname`. This will create a new folder with files for models, views, templates, and more. Apps make your project modular and reusable.
7
What does the settings.py file do?
The `settings.py` file stores all the important configurations of your project. It includes database settings, installed apps, security keys, static and media file paths, and more.
8
How do you run the Django development server?
You can start the server by typing `python manage.py runserver`. By default, the site runs at `http://127.0.0.1:8000/`. This server is only for development, not production.
9
What are URL patterns in Django?
URL patterns map a browser request to a specific view function. They are defined in the `urls.py` file. For example, when a user visits `/blog/`, Django uses the URL pattern to call the correct view and return a response.
10
What is the purpose of makemigrations and migrate commands?
`makemigrations` creates migration files based on changes in your models. `migrate` applies those migrations to the database so tables and fields are created or updated.
11
What is the Django admin panel?
The Django admin panel is a built-in web interface for managing your project’s data. You can add, update, or delete records without writing SQL queries. It is generated automatically from your models.
12
What are Django models?
Models are Python classes that define the structure of your database tables. Each model maps to a table, and each field maps to a column. Django’s ORM allows you to interact with models using Python instead of raw SQL.
13
What are Django templates used for?
Templates are HTML files that allow you to display data dynamically. They use special tags like `{{ variable }}` to insert values from views, and `{% %}` to add logic like loops or conditions.
14
How does Django handle static files?
Static files like CSS, JavaScript, and images are configured using `STATIC_URL` and `STATICFILES_DIRS` in settings. During development, Django serves them automatically. In production, they are usually served by a web server.
15
How does Django handle media files?
Media files are user-uploaded files such as profile pictures or documents. They are stored in the folder defined by `MEDIA_ROOT` and can be accessed using `MEDIA_URL`.
16
What are Django views?
Views are Python functions or classes that receive an HTTP request and return an HTTP response. Views connect models and templates, acting as the brain of the application.
17
What is Django ORM and why is it useful?
The Django ORM (Object Relational Mapper) allows you to interact with the database using Python code instead of SQL. For example, you can create a new record by calling `Model.objects.create()` instead of writing an INSERT query.
18
How do you register an app in Django?
After creating an app, you must add it to the `INSTALLED_APPS` list inside `settings.py`. This tells Django to include the app in the project.
19
What is the purpose of the __str__ method in models?
The `__str__` method defines how an object should be displayed as text. It helps you see meaningful names in the admin panel instead of object IDs.
20
What database does Django use by default?
By default, Django uses SQLite, a lightweight file-based database. For larger projects, you can switch to PostgreSQL, MySQL, or other databases by changing the settings.
