如何从Django中的模板更新列表中的单个项目？

# views.py
from django.shortcuts import render, redirect
from .models import Item
from .forms import UpdateItemForm

def item_list(request):
    items = Item.objects.all()
    return render(request, 'item_list.html', {'items': items})

def update_item(request, item_id):
    item = Item.objects.get(id=item_id)
    if request.method == 'POST':
        form = UpdateItemForm(request.POST, instance=item)
        if form.is_valid():
            form.save()
            return redirect('item_list')
    else:
        form = UpdateItemForm(instance=item)
    return render(request, 'update_item.html', {'form': form, 'item': item})

<!-- item_list.html -->
{% for item in items %}
    <p>{{ item.name }}</p>
    <form method="POST" action="{% url 'update_item' item.id %}">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Update</button>
    </form>
{% endfor %}

<!-- update_item.html -->
<form method="POST" action="{% url 'update_item' item.id %}">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Update</button>
</form>
