Is it possible to user this code like the first one instead of second?

def create_new(request):
    if request.method == 'POST':
        form = ArticleForm(request.POST)
        form.id_author = request.user.id
        if form.is_valid():
            form.save()
            return redirect('home')
    return render(request, 'main/create_new.html')

def create_new(request):
    if request.method == 'POST':
        form = ArticleForm(request.POST)
        if form.is_valid():
             article = form.save(commit=False)
             article.author = request.user
            article.save()
            return redirect('home')
    return render(request, 'main/create_new.html')

Is it possible to change the 2nd code into the first code?? it shows some kind of error

No, at first you always need to check whether the form is valid or not, then after you can save the form with commit=False which creates a temporary instance, then you should assign any value in that instance.

The second approach is correct.
