What are Django ModelForms and how do I use them?

Django ModelForms are a way to create forms based on your Django models. They automatically generate form fields for model attributes.

Can you show me an example of how to create a ModelForm?

Sure! First, you define your model, then create a ModelForm class like this:

from django import forms
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = '__all__'

How do I use this ModelForm in a view?

In your view, you can instantiate the form and handle form submission like this:

from django.shortcuts import render, redirect
from .forms import MyModelForm

def my_view(request):
    if request.method == 'POST':
        form = MyModelForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('success_url')
    else:
        form = MyModelForm()
    return render(request, 'template.html', {'form': form})
