问题 I am suffering an error with django and their custom Managers. I have this custom Manager: class CallManager(models.Manager): def get_queryset(self): return super(CallManager, self).get_queryset().filter(is_active=True) class Call(models.Model): ... # Data is_active = models.BooleanField(default=True) # Managers objects = models.Manager() # Default active = CallManager() # Active calls Ok, So now I am trying to retrive data from views.py (call/views.py) # Call list def call_list(request):

问题 I'm building a news website.I need display 48 hours most viewed news. So I need first to get the 48 hours news, and then get its pv. Currently I'm using a very complicated method which is from a tutorial: def get_two_days_read_data(content_type): today = timezone.now().date() dates = [] read_nums = [] for i in range(2, 0, -1): date = today - datetime.timedelta(days=i) dates.append(date.strftime('%m/%d')) read_details = ReadDetail.objects.filter(content_type=content_type, date=date) result =

问题 I am trying to avoid repeating the list of fields and model specifier in both a form and a (class based) view. This answer suggested defining a "meta class" that has the field list in it, and inheriting that class in both the form and the view. It works fine for the form, but the following code inheriting the list and target model into the view results in this error: TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()' I'm at a

问题 I have an orderform that is not saving the items ordered to the database. I am only getting the contact form saved. I have searched and can't find what I am doing wrong or missing in my views. Any help would be greatly appreciated. Thank you! Views: class OrderFormView(CreateView): model = Contact form_class = ContactForm template_name = 'orderform.html' success_url = 'thank-you' def get_context_data(self, **kwargs): context = super(OrderFormView, self).get_context_data(**kwargs) formsets =

问题 I'm building a news website.I need display 48 hours most viewed news, this part is in the detail.html page. Now I'm using this method. def newsDetailView(request, news_pk): news = get_object_or_404(News, id=news_pk) News.objects.filter(id=news_pk).update(pv=F('pv') + 1) time_period = datetime.now() - timedelta(hours=48) host_news=news.objects.filter(date_created__gte=time_period).order_by('-pv')[:7] return render(request, "news_detail.html", { 'news': news, 'host_news' : host_news }) It works

问题 Uploaded pdf file is showing correctly but selected client is not showing,Client will displayed in dropdown,if we select particular client and upload multiple pdf files,the selected client and files should display. models.py class Client_files(models.Model): Date = models.DateTimeField(default=datetime.now, blank=True) client = models.ForeignKey(Client, on_delete=models.CASCADE,null=True) client_process = models.ForeignKey(Client_Process, on_delete=models.CASCADE,null=True) File_Name = models

问题 I am looking to save the users last logout time.My idea was to add it to the users profile model. I am using Django 1.11.15 Example: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) ... last_logout = models.DateTimeField(blank=True, null=True) below is how I created my profile model just for reference def signup(request): if request.method == 'POST': form = UserCreateForm(request.POST or None) if form.is_valid(): new_user = form.save() Profile.objects

问题 I have an UpdateView that will display a form to either create the user profile or update the user profile. It works well, however, for some reason I can't get it to show the form errors. There should be form errors based on the ValidationErrors I have put in the model form. I suspect my views.py to be the cause of the form not displaying the errors. Here's my view: class ProfileSettings(UpdateView): model = Profile template_name = 'profile/settings.html' form_class = ProfileForm success_url

问题 So I've spent the day trying to chase down a custom thing that I wanted to achieve using FormView. When I use FormView with HTML form method="POST", I am able to get the desired result, mostly. If a user clicks to submit a form and an empty field exists, they get an error message telling them the form is required. I'm aware that I can make the ModelChoiceField required on the form, but was trying to implement my own logic for this. I found through my searching that if I'm not updating

问题 trying to display the final mark per student. But instead of just showing the result of sum , it displays a chunk of query set: for example: Annie <QuerySet [{'studName': None, 'attendance__sum': 3}, {'studName': 1, 'attendance__sum': 2}, {'studName': 2, 'attendance__sum': 1}]> and same goes to the rest of the students. I would like to display it like : Annie 2 Benny 3 Charlie 4 My view: def attStudName(request): studentName = MarkAtt.objects.all() mark = MarkAtt.objects.values('studName')
