Function-based vs class-based decision in Django - Quick Revision & Key Differences

Recall & Review

What is a function-based view (FBV) in Django?

A function-based view is a simple Python function that takes a web request and returns a web response. It is straightforward and easy to understand, suitable for simple logic.

What is a class-based view (CBV) in Django?

A class-based view is a Python class that provides methods to handle HTTP requests. It helps organize code better and supports reuse through inheritance and mixins.

When should you choose a function-based view over a class-based view?

Choose a function-based view when your view logic is simple and straightforward, like a single action or small page, because it is easier to write and understand.

What are the advantages of using class-based views?

Class-based views allow code reuse through inheritance, organize complex logic into methods, and provide built-in generic views for common tasks like displaying lists or forms.

How does Django handle HTTP methods differently in FBVs and CBVs?

In FBVs, you check the request method inside the function (like if request.method == 'POST'). In CBVs, you define separate methods like get() and post() for each HTTP method, making code cleaner.

Which Django view type is best for simple, one-action pages?

A Function-based view

B Class-based view

C Template view

D Middleware

Function-based views are simpler and better for straightforward tasks.

In class-based views, how do you handle a POST request?

A Override the dispatch() method only

B Check request.method inside a function

C Use a decorator

D Define a post() method

Class-based views handle HTTP methods by defining methods like post() for POST requests.

What is a key benefit of class-based views over function-based views?

A No need to import Django modules

B Better code reuse through inheritance

C Easier to write for simple pages

D Automatically faster response time

Class-based views support inheritance, which helps reuse and organize code.

Which view type requires you to manually check request.method?

A Template view

B Class-based view

C Function-based view

D Generic view

In function-based views, you check request.method yourself to handle different HTTP methods.

When might you prefer a class-based view?

A When your view has multiple HTTP methods and complex logic

B For a simple 'Hello World' page

C When you want to avoid using classes

D When you want to write less code for a single action

Class-based views help organize complex logic and multiple HTTP methods better.
