我有一张表格可以跟踪销售顾问的潜在客户和当前交易。但是，我陷入了创建交易的过程中，因为django一直给我错误＆＃34; ValueError：对于带有基数10的int（）的无效文字：＆＃34;当我尝试用字符串输入客户姓氏时。当我尝试使用整数lastname创建时，表单工作。

答案 0 :(得分：1)
错误几乎肯定来自这条线：
final_accessories = form.cleaned_data['lastname'],
因为final_accessories应该是一个整数，但是你传递的是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()
