Django Takeoff: Developing Modern Applications

Refer to the following code.

```py
def edit_post(request, detail_id):
    post = Posts.objects.get(id=detail_id)

    if request.method != 'POST':
        form = PostForm(instance=post)
    else:
        form = PostForm(request.POST, request.FILES, instance=post)
        if form.is_valid():
            form.save()
            return redirect('posts:all_posts')
