What are some examples of using model forms in Django?

Django model forms are a powerful way to create forms based on your models. For example, you can create a form for a 'Book' model that includes fields like title, author, and published date.

Can you show me a code example for a model form?

Sure! Here's a simple example:

from django import forms
from .models import Book

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

How do I use this form in a view?

You can use the form in a view like this:

from django.shortcuts import render
from .forms import BookForm

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

What template code do I need to display the form?

In your template, you can render the form like this:

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Submit</button>
</form>
