Ich hatte kürzlich Probleme mit FormView und stellte fest, dass die Verwendung von get_form_kwargs der richtige Weg war, dies zu tun.

Hier ist mein Code:

class InternalResetPasswordView(FormView):

template_name = 'reset_password.html'
form_class = forms.InternalPasswordResetForm

# success_message = "Password was reset successfully"

# To get request object

def get_form_kwargs(self):
    kwargs = super(InternalResetPasswordView, self).get_form_kwargs()
    kwargs['user'] = self.request.user
    return kwargs

def get_success_url(self):
    return reverse('user-detail', kwargs={'pk': self.request.user.id})

@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
    return super(InternalResetPasswordView, self).dispatch(*args, **kwargs)   

'''
def get_context_data(self, **kwargs):

    context = super(InternalResetPasswordView, self).get_context_data(**kwargs)
    context['InternalPasswordResetForm'] = context.get('form')

    return context


def get_form_kwargs(self):
    kwargs = super(InternalResetPasswordView, self).get_form_kwargs()
    kwargs['request'] = self.request
    return kwargs

'''
# self.request.user method obtained from
# https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-editing/
def form_valid(self, form):
    current_password = form.cleaned_data['old_password']
    new_password =  form.cleaned_data['new_password1']
    confirm_new_password = form.cleaned_data['new_password2']
    user = self.request.user
    if user.check_password(current_password) and new_password == confirm_new_password:
        user.set_password(new_password)
        user.save()
        # form.valid() redirects to get_success_url
    return super(InternalResetPasswordView, self).form_valid(form)

Nach dem Anschauendieser BeitragIch verstehe immer noch nicht, warum get_form_kwargs verwendet werden muss und warum self.request anstelle von self.request.user in diesem Fall verwendet wird__init__() got an unexpected keyword argument 'request'.

Könnte mir das jemand erklären?

Danke für all die Hilfe :)
