我已经看到有其他人和我一样有这个问题，但是尝试了所有这些解决方案后，他们似乎都没有帮助。我一直收到错误说：

我知道这个问题与其中一个字段有关，但不知道是什么，或者如何开始尝试修复它。我已经复制了相关文件，我认为这是解决这个问题所必需的，并且非常感谢我能为此提供任何帮助。

我会非常感谢任何人和任何花在这上面的时间，因为我一直在寻找这个问题的解决方案已经有一段时间了，并且无法修复它。再次感谢您的帮助
答案 0 :(得分：2)
usertype = models.IntegerField() - 是一个非空字段。
此处的问题是，您在表单usertype中设置的NormalSignUpForm在表单提交时未被提取，因此会发生违规。在保存用户实例时，您可以执行以下操作：
def normalsignup(request):
if request.method == 'POST':
form = NormalSignUpForm(request.POST)
if form.is_valid():
user = form.save(commit=False)
user.usertype = 1
form.save()
raw_password = form.cleaned_data.get('password1')
email = form.cleaned_data.get('email')
user = authenticate(username=email, password=raw_password)
.......
答案 1 :(得分：1)
当您在
中记录用户时，您不需要保存表单所以请改用
def normalsignup(request):
if request.method == 'POST':
form = NormalSignUpForm(request.POST)
if form.is_valid():
form= form.save(commit=False)
form.usertype = 1
form.save()
raw_password = form.cleaned_data.get('password1')
email = form.cleaned_data.get('email')
user = authenticate(email=email, password=raw_password)
login(request, user)
return redirect('home')
else:
form = NormalSignUpForm()
return render(request, 'normalsignup.html', {'form': form})
