What are Django model forms and how do I use them?

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

Can you show me a simple example of creating a model form?

Sure! First, define a model in your models.py, then create a form in forms.py using ModelForm. Here's a quick example:

from django import forms
from .models import MyModel

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

How do I use this form in a view?

In your views.py, you can use the form like this:

from django.shortcuts import render
from .forms import MyModelForm

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

What template code do I need to display the form?

You can display the form in your template like this:

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