Django：set_password不是哈希密码吗？

我在Django中制作了自定义用户注册表单/视图，以便可以通过其他模型添加其他用户属性。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，但是我发现保存的密码没有被散列。

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(),
        }

看法：

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，登录名无效。我在Admin上检查了用户信息，发现密码字段显示：无效的密码格式或未知的哈希算法。我还同步了数据库并打开了外壳程序，并手动检索了使用我的注册表单创建的用户对象，发现用户密码没有被散列，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创建的用户的密码会被哈希处理，但我的自定义表格不会进行哈希处理。文档说set_password（raw_password）自动处理哈希处理。
