Python “我的表单”字段将字符串输入视为无效

我有一个表格，记录潜在客户和当前与销售顾问达成的交易。然而，我在创建交易的过程中被卡住了，因为django在我尝试用字符串输入客户姓氏时，不断给我“ValueError:invalid literal for int（），base 10:”的错误。但是，当我尝试使用integer lastname创建时，表单可以工作

错误几乎肯定来自这一行：

final_accessories = form.cleaned_data['lastname'],

因为

final\u attachments

应该是一个整数，但是您正在传递lastname的值

为了避免这样的问题，您应该真正依赖ModelForm为您创建整个实例的能力。您可以通过

commit=False

方法分配客户实例：

if form.is_valid():
   deal = form.save(commit=False)
   deal.prospect = customer
   deal.save()

---

粘贴您的

url.py

和其他模型。您需要显示完整的回溯。试图转换为int的是什么？我想您可能在创建对象时遇到了

booked\u car=form.cleaned\u data['booked\u car']的问题。
booked\u car
必须是一个对象或其整数pk。它成功了！另外，感谢您的进一步解释，但是为什么在保存之前不必清理deal=form.save（commit=False）数据？我不理解您的问题-它确实需要清理，这就是为什么我们调用is_valid（）。
