Django modelform how to add a confirm password field?

问题

Here I need to add an extra confirmation password in my form.I used Django's modelform. I also need to validate both passwords. It must raise a validation error if password1 != password2.

Here is my forms.py:

class UserForm(forms.ModelForm):
    password=forms.CharField(widget=forms.PasswordInput())

    class Meta:
        model=User
        fields=('username','email','password')

class UserProfileForm(forms.ModelForm):
    YESNO_CHOICES = (('male', 'male'), ('female', 'female'))
    sex = forms.TypedChoiceField(choices=YESNO_CHOICES, widget=forms.RadioSelect)
    FAVORITE_COLORS_CHOICES=(('red','red'),('blue','blue'))
    favorite_colors = forms.MultipleChoiceField(required=False,widget=forms.CheckboxSelectMultiple, choices=FAVORITE_COLORS_CHOICES)
    dob = forms.DateField(widget=forms.DateInput(format = '%d/%m/%Y'), 
                                 input_formats=('%d/%m/%Y',))

    class Meta:

        model=UserProfile
        fields=('phone','picture','sex','favorite_colors','dob')

And here is my registration function:

def register(request):
    registered = False
    if request.method == 'POST':
        user_form = UserForm(data=request.POST)
        profile_form = UserProfileForm(data=request.POST)



        if user_form.is_valid() and profile_form.is_valid():
            user = user_form.save(commit=False)
            user.set_password(user.password)
            user.save()
            profile = profile_form.save(commit=False)
            profile.user = user
            if 'picture' in request.FILES:
                profile.picture = request.FILES['picture']
            profile.save()
            registered = True
        else:
            print user_form.errors, profile_form.errors
    else:
        user_form = UserForm()
        profile_form = UserProfileForm()

    return render(request,
            'mysite/register.html',
            {'user_form': user_form, 'profile_form': profile_form, 'registered': registered} )

Use clean like

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

    def clean(self):
        cleaned_data = super(UserForm, self).clean()
        password = cleaned_data.get("password")
        confirm_password = cleaned_data.get("confirm_password")

        if password != confirm_password:
            raise forms.ValidationError(
                "password and confirm_password does not match"
            )

回答2:

def clean(self):
    cleaned_data = super(UserAccountForm, self).clean()
    password = cleaned_data.get("password")
    confirm_password = cleaned_data.get("confirm_password")

    if password != confirm_password:
        self.add_error('confirm_password', "Password does not match")

    return cleaned_data

Try this for forms.py:

class UserForm(forms.Form):
    password = forms.CharField(widget=forms.PasswordInput())
    password_confirm = forms.CharField(widget=forms.PasswordInput())

    class Meta:
        model = User
        fields=('username','email','password')

And this in views.py:

if user_form.is_valid() and profile_form.is_valid() and user_form.cleaned_data['password'] == user_form.cleaned_data['password_confirm']:
    ...
elif user_form.data['password'] != user_form.data['password_confirm']:
    user_form.add_error('password_confirm', 'The passwords do not match')
