Question

if RegistrationForm.is_valid() and employeeForm.is_valid(): TypeError: is_valid() missing 1 required positional argument: 'self'

我有这个错误，我找不到来源。我错过了什么？

@transaction.atomic
def create_view(request):
    if request.method == 'POST':
        user_form = RegistrationForm(request.POST)
        profile_form = employeeForm(request.POST or None,request.FILES or None)
        if RegistrationForm.is_valid() and employeeForm.is_valid():
            user = RegistrationForm.save()
            user.refresh_from_db()
            profile_form = employeeForm(request.POST, instance=user.employeemodel)

            profile_form.full_clean()
            profile_form.save()
            return redirect('emp_list')
    else:
        user_form = RegistrationForm()
        profile_form = employeeForm()
    return render(request,'create_employee.html',{'userform':user_form,'profileform':profile_form})

在使用表单时，应使用实例对象而不是类对象。所以它应该是user_form.is_valid() and profile_form.is_valid()

user_form = RegistrationForm(request.POST)
profile_form = employeeForm(request.POST or None,request.FILES or None)
if user_form.is_valid() and profile_form.is_valid():
    user = user_form.save()
    user.refresh_from_db()
    profile_form = employeeForm(request.POST, instance=user.employeemodel)
    profile_form.full_clean()
    profile_form.save()
    return redirect('emp_list')

save()方法相同：user = user_form.save()

TypeError：is_valid（）缺少1个必需的位置参数：＆＃39; self＆＃39;
