How do I use model forms in Django?

To use model forms in Django, you first need to create a model and then create a form class that inherits from forms.ModelForm.

Can you show me a simple example?

Sure! First, define a model in models.py like this:

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)

Then, create a model form in forms.py:

class BookForm(forms.ModelForm):
    class Meta:
        model = Book
        fields = ['title', 'author']

How do I use this form in a view?

In your view, you can use the form like this:

from .forms import BookForm

def create_book(request):
    if request.method == 'POST':
        form = BookForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('success')
    else:
        form = BookForm()
    return render(request, 'create_book.html', {'form': form})
