创建用户时Django表单不保存密码

Question

我为我的 django 应用制作了一个自定义表单，允许用户为网站注册自己。

这是我的 django 应用程序的表单：

class TeacherRegistrationForm(UserCreationForm):
    email = forms.EmailField(required = True)
    school = forms.CharField(required = True)
    subject = forms.CharField(required = True)
    head_of_subject = forms.BooleanField(required = False)
    identification_code = forms.CharField(required = True)

    def __init__(self, *args, **kwargs):
        super(TeacherRegistrationForm, self).__init__(*args, **kwargs)
        self.fields['username'].help_text = ''
        self.fields['password2'].help_text = ''


    class Meta:
        model = User

        fields = (
            'username',
            'first_name',
            'last_name',
            'email',
            'school',
            'identification_code',
            'subject',
            'head_of_subject',
            'password1',
            'password2'            
        )

    def save(self, request):
        form = TeacherRegistrationForm(request.POST)
        user = User.objects.create(first_name=self.cleaned_data['first_name'],
                            last_name=self.cleaned_data['last_name'],
                            email=self.cleaned_data['email'],
                            username=self.cleaned_data['username'],
                            password=self.cleaned_data['password1']
                            )

        teacher_profile = TeacherProfile.objects.create(user=user,
                                                        school=self.cleaned_data['school'],
                                                        subject=self.cleaned_data['subject'],
                                                        head_of_subject=self.cleaned_data['head_of_subject'],
                                                        )


        return user, teacher_profile

这是视图的相关部分：

if request.method == 'POST':

        form = TeacherRegistrationForm(request.POST)

        entered_school_name = form['school'].value()
        entered_school_id = form['identification_code'].value()

        actual_school_id = SchoolProfile.objects.get(school_name__exact = entered_school_name).identification_code

        if form.is_valid()and (entered_school_id == actual_school_id):

            user, teacher_profile = form.save(request)

            return render(request, 'accounts/home.html')
        else:
            args = {'form': form}
            return render(request, 'accounts/reg_form.html', args)

当我按下提交时，用户被创建，但是没有为用户设置密码

没有必要触摸属于 User 的任何字段，实际上您不应该这样做，而是让 UserCreationForm 处理它，因为那里对密码进行了一些特殊处理。

这样做，在您的表单类保存方法中：

def save(self):
    user = super(TeacherRegistrationForm, self).save()
    teacher_profile = TeacherProfile(
        user=user,
        school=self.cleaned_data['school'],
        subject=self.cleaned_data['subject'],                   
        head_of_subject=self.cleaned_data['head_of_subject']
    )
    teacher_profile.save()
    return user, teacher_profile

这将产生 TeacherRegistrationForm，它是 UserCreationForm 的一个子类，而后者又是 ModelForm 的一个子类。它将做 ModelForm 应该做的事情，即当你将自己保存到数据库（用户表）中调用它的保存方法。所以这一切都为你完成了。然后，您只需处理为其他模型添加到表单中的额外字段。

注意我使用模型save() 方法而不是使用create()，在这种情况下完成相同的事情.. 但您可以稍后修改表单代码以允许相同的表单编辑现有模型而不是只需创建一个新的。如果您也希望我解释一下，请告诉我。

尝试像这样编辑您的表单，

def save(self): 
    user = User.objects.create_user(username=self.cleaned_data['username'], password=self.cleaned_data['password1']) 
    user.first_name = self.cleaned_data['first_name']
    user.last_name = self.cleaned_data['last_name']
    user.email = self.cleaned_data['email']
    user.save()
    teacher_profile = TeacherProfile.objects.create(user=user, school=self.cleaned_data['school'], subject=self.cleaned_data['subject'], head_of_subject=self.cleaned_data['head_of_subject'] ) 
    return user, teacher_profile

使用User.objects.create_user() 而不是objects.create。

我看不出将request 传递到保存方法中的意义。您可以删除该部分。 save 方法在执行form.save() 时被调用。另外，实际上不需要在表单保存方法中再次保存表单。

不需要以自定义方式保存用户，您继承了UserCreationForm，它将在设置密码和验证后返回用户实例因此您将在超级调用中获得直接用户实例。

def save(self, request):       
   user = super(TeacherRegistrationForm, self).save()
   teacher_profile = TeacherProfile.objects.create(user=user,                                         
                      school=self.cleaned_data['school'], 
                      subject=self.cleaned_data['subject'],                                                            
                      head_of_subject=self.cleaned_data['head_of_subject'],
                    )
   return user, teacher_profile
