What are some examples of class-based views in Django?

Class-based views in Django provide an object-oriented way to define views. For example, you can use ListView to display a list of objects.

Can you give me a code snippet for a ListView?

Sure! Here's a simple example:

from django.views.generic import ListView
from .models import MyModel

class MyModelListView(ListView):
    model = MyModel
    template_name = 'mymodel_list.html'
    context_object_name = 'mymodels'

This will create a view that lists all instances of MyModel.

What about using a CreateView?

A CreateView is used to create a new object. Here's an example:

from django.views.generic import CreateView
from .models import MyModel

class MyModelCreateView(CreateView):
    model = MyModel
    template_name = 'mymodel_form.html'
    fields = ['field1', 'field2']
    success_url = '/success/'

This view will handle the creation of a new MyModel instance.

How do I handle form validation in class-based views?

You can override the form_valid method in your view to handle form validation. For example:

def form_valid(self, form):
    # Custom validation logic here
    return super().form_valid(form)
