Question

我在Django中创建了一个自定义用户注册表单/视图，以便我可以通过不同的模型包含其他用户属性。我已经使用set_password将新创建的用户的密码设置为在表单中输入的密码，但我发现保存的密码没有经过哈希处理。

形式：

class UserForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput())
class Meta:
    model = User
    fields = ('username', 'email', 'password')


class StudentForm(forms.ModelForm):
    class Meta:
        model = Student
        fields = ('theclass',)
        widgets = {
            'theclass': forms.CheckboxSelectMultiple(),
        }

class TeacherForm(forms.ModelForm):
    class Meta:
        model = Teacher
        fields = ('theclass',)
        widgets = {
        'theclass': forms.CheckboxSelectMultiple(),
        }

视图：

def register_student(request):
context = RequestContext(request)
registered = False
if request.method == 'POST':
    user_form = UserForm(data=request.POST)
    student_form = StudentForm(data = request.POST)

    if user_form.is_valid() and student_form.is_valid():
        user = user_form.save()
        user.set_password(user.password)

        user.save

        student = student_form.save(commit = False)
        student.user = user
        student.save()
        registered = True
else:
    user_form = UserForm()
    student_form = StudentForm()
return render_to_response('classapp/register_student.html', {'user_form': user_form, 'student_form': student_form, 'registered': registered}, context)

def register_teacher(request):
    context = RequestContext(request)
    registered = False
    if request.method == 'POST':
        user_form = UserForm(data=request.POST)
        teacher_form = TeacherForm(data = request.POST)
    if user_form.is_valid() and teacher_form.is_valid():

        user = user_form.save()

        user.set_password(user.password)

        user.save

        teacher = teacher_form.save(commit = False)
        teacher.user = user
        teacher.save()
        registered = True
else:
    user_form = UserForm()
    teacher_form = TeacherForm()
return render_to_response('classapp/register_teacher.html', {'user_form': user_form, 'teacher_form': teacher_form, 'registered': registered}, context)

当我通过此表单注册用户时，登录无效。我检查了Admin上的用户信息，发现密码字段说： 无效的密码格式或未知的散列算法。 我还同步了db并打开了shell并手动检索了使用我的注册表创建的用户对象，发现用户密码没有被哈希，如下所示：

>>> from django.contrib.auth.models import User
>>> user = User.objects.get(username = "username")
>>> user.password
u'password'
>>> user = User.objects.get(username = "superuser")
>>> user.password
u****hashed password****

使用Admin创建的用户已经对其密码进行了哈希处理，但我的自定义表单没有。文档说set_password（raw_password）会自动处理哈希。

Answer 1

set_password仅创建哈希密码;它不会保存数据中的值。请致电save()以实际保存。

在您的观点中，我认为应该是

user.save()

以下

user.set_password(user.password)

您没有写括号（括号）。这就是为什么在散列密码后没有调用save方法的原因。

set_password 方法适用于 django 3.2 版

自定义 singup django 3.2

确保变量不传递空值。对于开发，您可以在传递给 set_password 方法之前进行打印。

def user_register(request):

  if (request.method == 'POST'):
        username = request.POST.get('username')
      
        password = request.POST.get('password')
  print(password, type(password))
  #make sure the password not passed null
  user = User.objects.create_user(
            email=email,
            name=username,  
            password=password,
        )      
  user.set_password(password)
  user.save()

你如何使用 django shell 进行测试。

python manage.py shell

此处列出 django shell 命令


from .models import user_type, User

user = User.objects.create_user(email="ll55@gmail.com",password="uU123456",name="le5")
user.set_password("uU123456")
user.save()



u = User.objects.get(name="as6")
u.name
u.password

Django：set_password不是哈希密码吗？
