Django 中的 2 个表单、1 个视图、2 个 SQL 表

我正在努力了解如何将两个 django 表单中的数据提交到两个单独的数据库表中相同的观点。我只想要一个提交按钮。尽管this https://stackoverflow.com/questions/1395807/proper-way-to-handle-multiple-forms-on-one-page-in-django问题让我更接近解决方案，我收到错误并且数据没有写入数据库。我认为这段代码实际上是相互检查两个表单，而不是一次性提交两个表单。有任何想法吗？

这是我尝试过的：

对于一种形式 --> 一张表。这有效，所以这是一个开始。

# views.py
def BookFormView(request):
    if request.method == 'POST':
    form = BookForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect("/books/")
    else:
        form = BookForm()
    return render(request, 'books/createbooks.html',
              {'form' : form})

但是，当我从 forms.py 添加此表单以获取后续的 views.py 时，我得到local variable 'book_form' referenced before assignment。这通常是一个容易解决的全局变量与局部变量问题，但我不知道在这种情况下这意味着什么。

def BookFormView(request):
    if request.method == 'POST':
        if 'book' in request.POST:
            book_form = BookForm(request.POST, prefix='book')
            if book_form.is_valid():
                book_form.save()
                return HttpResponseRedirect("/books/")

            bookdetailsform = BookDetailsForm(prefix='bookdetails')
        elif 'bookdetails' in request.POST:
            bookdetailsform = BookDetailsForm(request.POST, prefix='bookdetails')
            if bookdetailsform.is_valid():
                bookdetailsform.save()
                return HttpResponseRedirect("/books/")

            book_form = BookForm(prefix='book')
    else:
        book_form = BookForm(prefix='book')
        bookdetailsform = BookDetailsForm(prefix='bookdetails')
    return render(request, 'books/createbook.html',
            {'book_form' : book_form,
             'bookdetailsform': bookdetailsform})

根据问题的评论：

def BookFormView(request):
    if request.method == 'POST':
            book_form = BookForm(request.POST, prefix='book')
            bookdetailsform = BookDetailsForm(request.POST, prefix='bookdetails')
            if book_form.is_valid() and bookdetailsform.is_valid():
                book_form.save()
                bookdetailsform.save()
                return HttpResponseRedirect("/books/")
    else:
        book_form = BookForm(prefix='book')
        bookdetailsform = BookDetailsForm(prefix='bookdetails')
    return render(request, 'books/createbook.html', 
                  {'book_form': book_form, 'bookdetailsform': bookdetailsform})
