Question

我很难理解如何将两个django表单中的数据从相同的视图提交到两个单独的数据库表中。我只想要一个提交按钮。虽然this问题使我更接近解决方案，但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种形式，而不是一次性提交两种形式。有什么想法吗？

以下是我尝试的内容：

对于一种形式 - ＆gt;一张桌子。这是有效的，所以它是一个开始。

# 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中添加此表单以获取后续的views.py时，我得到local variable 'book_form' referenced before assignment。这通常是一个容易修复的全局与局部变量问题，但我不知道在这种情况下它意味着什么。

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})

Answer 1

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})

Answer 2

我认为问题在于，当用户提交bookdetails帖子请求时，它将在if 'book' in request.POST:条件下处理。为什么呢？
因为字符串bookdetails包含字符串book，所以无论它们的请求类型如何，它都将以if book in request.POST:条件处理。

我相信如果条件问题是第一步，那就解决这个问题。
