*Course Name:* Python Django - The Practical Guide
*Lecture:* 134-Class Based Views
*Description:*
In this lecture, we will discuss Class Based Views (CBVs) in Django. CBVs are a powerful and flexible way to write Django views. They provide a number of advantages over traditional function-based views, including:
*Reduced boilerplate code:* CBVs eliminate the need for much of the boilerplate code that is typically required for function-based views. This makes your code more concise and easier to maintain.
*Increased reusability:* CBVs can be easily reused across different applications. This can save you a lot of time and development effort.
*Improved separation of concerns:* CBVs help to improve the separation of concerns in your Django applications. This makes your code more modular and easier to test.
In this lecture, we will cover the following topics:
*What are CBVs?*
*How to write CBVs*
*Advantages of CBVs*
*Disadvantages of CBVs*
*When to use CBVs*
We will also take a look at some of the most common CBV mixins that are available in Django.
*Example:*
```python
class MyView(ListView):
model = MyModel
context_object_name = 'mymodels'
def get_queryset(self):
return super().get_queryset().filter(published=True)
```
This code defines a CBV that displays a list of `MyModel` objects. The `ListView` mixin provides the necessary functionality for displaying a list of objects. The `get_queryset()` method overrides the default method to filter the queryset to only include objects that are published.
