django-class-based-views

问题 I've been learning Django and one source of confusion I have is with class based views and when to override the get method. I've looked through the documentation and it explains what get does but it doesn't explain when I should override get. I originally created a view this way: class ExampleView(generic.ListView): template_name = 'ppm/ppm.html' paginate_by = 5 def get(self, request): profiles_set = EmployeeProfile.objects.all() context = { 'profiles_set': profiles_set, 'title': 'Employee

问题 I'm putting together a project management website for my team using django. My base template includes a sidebar menu which contains a list of all projects and users, linking to a DetailView for that user or project, respectively. My problem is that I need to provide the User and Project models to every view so that I can render that sidebar.

问题 I do a request to my local server using postman like this: As you can see it's a post request. In my view ( APIView ) I need access to the json data.

问题 The code below paginates the queryset but how can I paginate context['guser1'] class AuthorList(ListView): template_name = 'authorList.html' paginate_by = 10 queryset = Author.objects.order_by('date') def get_context_data(self, **kwargs): context = super(AuthorList, self).get_context_data(**kwargs) if int(self.kwargs['user_id']) != self.request.user.id: raise PermissionDenied if self.request.user.username == 'guest': raise PermissionDenied context['guser1'] = Author.objects.order_by('date')

问题 I am currently trying to bring my function-based view into a class-based view. The question I am currently struggling with is if I should either trying to move it into a TemplateView with FormMixin or in a FormView with ContextMixin. Do you have any tips on how to decide what's best? def event_detail_view(request, event, organizer): queryset = Event.objects.filter(organizer__slug=organizer) event = get_object_or_404(queryset, slug=event) tickets = collect_all_tickets(event, organizer)

问题 I have tried this for a couple of hours, and looked at alot of documentation, but I cant get it right. I dont think I'll see a solution to this anytime soon, so maybe someone could see what is wrong? I want a view to show all my categories and all my connected entries to those categories.

I have tried def get_initial(self): with no luck (it give me error). If anyone can point out what I am doing wrong…thanks Models.py: class School(models.Model): school_pk = models.AutoField(primary_key=True) name = models.CharField(max_length

问题 I'm trying to do it this way, but it doesn't work. class MyView(View): def options(self, request, *args, **kwargs): """ Handles responding to requests for the OPTIONS HTTP verb. """ response = http.HttpResponse() if self.kwargs.has_key('xml'): response['Content-Type'] = 'text/xml; charset=utf-8' return response 回答1: I think the key point is render_to_response in django.views.generic.base , whose code is this: def render_to_response(self, context, **response_kwargs): """ Returns a response,

问题 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
