Mehrere Formular-Klassen, die in django-generic (Klasse) Ansichten

Vorhandenen Felder aus zwei Modelle auf einer einzigen Seite anzeigen

Erweiterung von django.Blick.generisches.View-Klasse und überschreiben Sie bekommen(Anfrage) und post(Anfrage) - Methoden.

Dies ist, wie ich das geschafft habe.

Ich bin mit Django 1.11.

Dies ist, wie meine form (Bestand aus zwei Formen) sieht wie folgt aus:

Meine Ansicht Klasse, das macht mein zwei Formen:

from django.views.generic import View

class UserRegistrationView(View):
    # Here I say which classes i'm gonna use
    # (It's not mandatory, it's just that I find it easier)
    user_form_class = UserForm
    profile_form_class = ProfileForm
    template_name = 'user/register.html'

    def get(self, request):
        if request.user.is_authenticated():
            return render(request, 'user/already_logged_in.html')
        # Here I make instances of my form classes and pass them None
        # which tells them that there is no additional data to display (errors, for example)
        user_form = self.user_form_class(None)
        profile_form = self.profile_form_class(None)
        # and then just pass them to my template
        return render(request, self.template_name, {'user_form': user_form, 'profile_form': profile_form})

    def post(self, request):
        # Here I also make instances of my form classes but this time I fill
        # them up with data from POST request
        user_form = self.user_form_class(request.POST)
        profile_form = self.profile_form_class(request.POST)

        if user_form.is_valid() and profile_form.is_valid():
            user = user_form.save(commit=False)
            user_profile = profile_form.save(commit=False)

            # form.cleaned_data is a dictionary which contains data validated
            # by fields constraints (Say we have a field which is a number. The cleaning here would 
            # be to just convert a string which came from the browser to an integer.)
            username = user_form.cleaned_data['username']
            password = user_form.cleaned_data['password']

            # This will be clarified later 
            # You can save each object individually if they're not connected, as mines are (see class UserProfile below)
            user.set_password(password)
            user.userprofile = user_profile
            user.save()

            user = authenticate(username=username, password=password)

            if user is not None:
                if user.is_active:
                    login(request, user)
                return redirect('user:private_profile')

        # else: # form not valid - each form will contain errors in form.errors
        return render(request, self.template_name, {
            'user_form': user_form,
            'profile_form': profile_form
        })

Ich habe eine User und UserProfile Modelle.
User ist django.contrib.auth.models.User und UserProfile ist wie folgt:

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    friends = models.ManyToManyField('self', null=True, blank=True)
    address = models.CharField(max_length=100, default='Some address 42')

    def get_absolute_url(self):
        return reverse('user:public_profile', kwargs={'pk': self.pk})

    def __str__(self):
        return 'username: ' + self.user.username + '; address: ' + self.address

    @receiver(post_save, sender=User) # see Clarification 1 below
    def create_user_profile(sender, instance, created, **kwargs):
        if created: # See Clarification 2 below
            UserProfile.objects.create(user=instance, address=instance.userprofile.address)

    @receiver(post_save, sender=User)
    def update_user_profile(sender, instance, **kwargs):
        instance.userprofile.save()

Klarstellung 1: @Empfänger(post_save, Absender=User)

• wenn der Benutzer gespeichert wird (ich schrieb Benutzer.save() irgendwo (user ist eine Instanz der Klasse User) ) UserProfile gespeichert.

Klarstellung 2: wenn erstellt: (Klärung aus der Sicht der Klasse)

• Wenn der Benutzer ERSTELLT wird, eine UserProfile
  wobei user = User-Instanz, die gerade jetzt vorgelegt durch ein UserForm

• Adresse gesammelt von ProfileForm und Hinzugefügt, um die Benutzer-Instanz vor
  aufrufenden Benutzers.save()

Ich habe zwei Formulare:

UserForm:

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput(render_value=True), required=True)
    password_confirmation = forms.CharField(widget=forms.PasswordInput(render_value=True), required=True)

    first_name = forms.CharField(required=True)
    last_name = forms.CharField(required=True)

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

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

        if password != password_confirmation:
            self.fields['password'].widget = forms.PasswordInput()
            self.fields['password_confirmation'].widget = forms.PasswordInput()

            self.add_error('password', "Must match with Password confirmation")
            self.add_error('password_confirmation', "Must match with Password")
            raise forms.ValidationError(
                "Password and Password confirmation do not match"
            )

ProfileForm:

class ProfileForm(forms.ModelForm):
    class Meta:
        model = UserProfile
        fields = ('address',)

Ich hoffe, dass ich deine Frage verstanden sich gut und, dass dies helfen wird Sie (und andere kommen). 🙂
