Let's say my app is like a forum, but that each post has a group of people which may see it. SecretPost(Model): can_see = myapp.main.models.GroupOfUsers() I want to write a view which restricts users' access to these posts, and I'd prefer to use decorators, since that's how I've been handling access control everywhere else. SecretPostView(DetailView): """Can only be seen by members of its group""" @method_decorator(part_of_its_group) def dispatch(self, request, *args, **kwargs): return super(SecretPostView, self).dispatch(request, *args, **kwargs) But when dispatch() is called, I don't know

I have a model that uses different validation for its name field depending on whether the object was created by a user or by the system. class Symbol(models.Model): name = models.CharField(_('name'), unique=True, max_length=64) creator = models.ForeignKey('User', null=True, on_delete=models.CASCADE) def is_system_internal(self): """ whether or not this Symbol belongs to the system rather than having been created by a user """ return (self.creator is None) def clean(self): """ ensure that the Symbol's name is valid """ if self.is_system_internal(): if not re.match("^_[a-zA-Z0-9\-_]+$", self

I want to use the same template to display records from different models in django, with generic class viewers. The generic class viewers already accept most of the arguments needed in the template, except for one. How can I pass this extra argument in the context to the template? I have tried passing it as the third (extra) argument in the urlconf, without success: # in urlconf.py url(r'^processador/(?P<pk>[\w-]+)/$', UpdateView.as_view( model=Processador, template_name='model_form.html', success_url=reverse_lazy('processador-list'), ), {'extrainfo': "Processador"}, name='processador-detail'

Is there a established way that i validate an object in the dispatch without making an extra database call when self.get_object() is called later in get/post? Here is what i have so far (slightly altered for this question): class CourseUpdateView(UpdateView): def dispatch(self, request, *args, **kwargs): self.request = request self.kwargs = kwargs self.object = self.get_object() if self.object.is_online: messages.warning(request, "Sorry this one can't be updated") return redirect("course:detail", pk=self.kwargs['pk']) # this is going to call self.get_object again isn't it? return UpdateView

In continuation of my struggle with WeekArchiveView , how do I paginate it by week? All I want is: to know if there is next / previous week available; in case there is, provide a link in the template. I'd like it to also skip empty weeks. The source shows get_next_day / get_prev_day and get_next_month / get_prev_month are available, but nothing for weeks. That is definitely interesting. Sure enough MonthMixin includes get_next_month / get_prev_month methods, and DayMixin includes get_next_day / get_prev_day methods. However, both YearMixin and WeekMixin have no functional equivalent in their

I'm trying to track the user that created an object using a CreateView and I'm doing it exactly like it's done in documentation ( https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-editing/ , Models and request.user) except I don't use login_required() decorator but LoginRequiredMixin from django-braces instead. My model: class Contact(models.Model): owner = models.ForeignKey(User, editable=False) first_name = models.CharField(max_length=255,) last_name = models.CharField(max_length=255,) email = models.EmailField() My view: class CreateContactView(LoginRequiredMixin,
