update objects before access using DetailView (Django)
I am using DetailView in Django. I have a model including certain time field(taxi_time), and I would like compare the time and now. If taxi_time < datetime.now(), I want to change a field(taxi_is_closed) in the model from False to True. So before users access the post, I need to (automatically) check the time and modify taxi_is_closed. How can I do it? My View.py : @method_decorator(login_required(login_url='/login/'), name='dispatch') class RecruitView(PermissionRequiredMixin, generic.DetailView): model = Recruit template_name = 'taxi/recruit.html' def has_permission(self): return self.request.user.profile.email_confirmed def handle_no_permission(self): error_message = '아직 인증이 완료되지 않았습니다. 이메일 인증을 완료해주세요! :)' if self.raise_exception: raise PermissionDenied(self.get_permission_denied_message()) return render(self.request, 'taxi/info.html', {'error_message': error_message}) def get_context_data(self, **kwargs): context = super(RecruitView, self).get_context_data(**kwargs) #pdb.set_trace() img_var = self.get_object().taxi_popnow*10 + self.get_object().taxi_poptot img_name = str(img_var) context['img_name'] = img_name context['ApplyForm'] = ApplyForm() return context MY model.py : class Recruit(models.Model): taxi_time = models.TimeField('출발 시각') taxi_is_closed = models.BooleanField('마감', default=False) def chk_closed(self): now = datetime.datetime.now() taxi_datetime = datetime.datetime.combine(self.taxi_date, self.taxi_time) is_full = self.taxi_poptot <= self.taxi_popnow is_past = taxi_datetime <= now if (is_full or is_past): self.taxi_is_closed = True else: self.taxi_is_closed = False self.save() I picked only related code. -

Django Pagination and Ajax Refresh
I got this simple Django model, class Person(models.Model): name = models.CharField(max_length=100) that I want to display using paginator showing only 1 item (name) per page. A left and right arrow when pressed will show the previous and next item in the paginator queryset using Ajax refreshing only the name. I'm using jQuery for Ajax. Question is when refreshing by Ajax how do you know the current page number and in this case the current page number corresponded to the currently shown name and so to display the next or previous item in the list using page_next and page_previous? -

Django urls.py mistaking two close urls
i'm adding forms to my app to modify my lobbys (my custom model). In urls.py, here is my urlpattern: urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^lobbys/$', views.LobbyListView.as_view(), name='lobbys'), url(r'^lobby/(?P<pk>[\w-]+)/$', views.LobbyDetailView.as_view(), name='lobby-detail'), url(r'^lobby/create/$', views.LobbyCreate.as_view(), name='lobby_create'), url(r'^lobby/(?P<pk>\d+)/update/$', views.LobbyUpdate.as_view(), name='lobby_update'), url(r'^lobby/(?P<pk>\d+)/delete/$', views.LobbyDelete.as_view(), name='lobby_delete'), ] The problem is the following: The third url is supposed to link to a single lobby template identifed with a UUID field as the primary key. Without the three last lines everything worked fine, but when I added my three urls for the forms, I'm getting the error Exception Value: ["'create' is not a valid UUID."] I understand urls.py is taking "create" as a primary key instead of considering it as an urls to an other view. How can I bypass this problem? Thank you very much. -

When should celery be restarted?
I use celery to process asynchronous tasks. I understand that when I update the code within these tasks, or When i want to register a new task, then I must restart celery to see the reflection of these changes. Do I need to restart celery if I update some code, that is within the same file, but not a registered celery task? Are there other reasons on when I should restart celery during a deploy? thanks much! -
Django custom settings for app
I am currently developing an app for django that needs to have some custom settings that can be changed at runtime by admin users, and those settings have to be accessible to another separate system that uses the same database. On one hand, we could store those settings in a json file and have it accessible to both systems, as only the django system will actually make any changes to the settings. On the other hand, we could just store those settings as a lone entry in the database. The first choice seems quite cumbersome to deal with, and might result in some problems of multiple accesses, while the other would need a whole table in the database for a single entry. Is any of these ideas any good, or is there something I'm overlooking? -
How to fix Django's the view didn't return an HttpResponse object. It returned None instead?
I'm getting the following error: The view KSUvity.authentication.views.registerAttendee didn't return an HttpResponse object. It returned None instead I think it's because there is a logical error in my function. I have several if and else statements to check several conditions.

pylint_django throwing exception

How to pass extra formatting info through form into template?
I am working on a Django based form. I am using widget-tweaks. The template portion looks like: ... {% for field in profileForm.visible_fields %} <div class="form-group"> {{ field.label_tag }} {% if profileForm.is_bound %} {% if field.errors %} {% render_field field class="form-control is-invalid" %} {% for error in field.errors %} <div class="invalid-feedback"> {{ error }} </div> {% endfor %} {% else %} {% render_field field class="form-control is-valid" %} {% endif %} {% else %} {% render_field field class="form-control" %} {% endif %} {% if field.help_text %} <small class="form-text text-muted">{{ field.help_text }}</small> {% endif %} </div> {% endfor %} <button type="submit">Submit</button> </form> ...

Here is my simplified views.py code that works for ordering the results: class AssetViewSet(viewsets.GenericViewSet, AssetPaginationMixin,): queryset = Asset.objects.all() pagination_class = AssetPagination serializer_class = serializers.AssetSerializer filter_backends = (OrderingFilter, ) ordering_fields = ('id', 'session_id') filter_class = AssetFilterSet def list(self, request): assets = self.filter_queryset(self.get_queryset()) serializer = self.get_serializer(assets, many=True) return Response(serializer.data) And here is the code that works for filtering: class AssetViewSet(viewsets.GenericViewSet, AssetPaginationMixin,): queryset = Asset.objects.all() pagination_class = AssetPagination serializer_class = serializers.AssetSerializer filter_backends = (OrderingFilter, ) ordering_fields = ('id', 'session_id') filter_class = AssetFilterSet def list(self, request): assets = AssetFilterSet(request.query_params) serializer = self.get_serializer(assets, many=True) return Response(serializer.data) And finally, my filters.py code: class AssetFilterSet(django_filters.FilterSet): project_id = django_filters.NumberFilter() submitted = django_filters.TypedChoiceFilter(choices=BOOLEAN_CHOICES, coerce=strtobool) class Meta: model = Asset fields = ['project', 'submitted'] The only difference is the first line in list(). For some reason, it seems like the AssetFilterSet needs to be applied directly within list() in order to take effect and is otherwise bypassed if I use self.filter_queryset in … -
django testing passing request.user to foreignKey field, "Event.creator" must be a "User" instance
I am trying to write test for a view that creates an event model object. The event model contains a foreignKey field that references auth user as the creator of the model object. In the test I tried logging in the user which I assumed would set the request.user to the user logged in. The view that is being tested references request.user when creating the event the works fine when triggered normally through ajax but when I run the test I keep getting the error below. Also I have tried creating the user within the test function instead of referencing the user created at "class.setupTestData()", same error. error ValueError: Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x108ae9cc0>>": "Event.creator" must be a "User" instance. model class Event(models.Model): name = models.CharField(max_length=200) event_type = models.CharField(max_length=200, null=True) creator = models.ForeignKey(User, on_delete=models.CASCADE, null=True) attendees = models.ManyToManyField(User, related_name='attendees') start_date = models.DateField(null=True) start_time = models.TimeField(null=True) end_date = models.DateField(null=True) end_time = models.TimeField(null=True) location = models.CharField(max_length=200, null=True) date_created = models.DateTimeField(auto_now_add=True) description = models.TextField() def __str__(self): return self.name view def createEvent(request): # dec vars event_title = str(request.POST['event-title']).title() event_type = str(request.POST['event-type']) event_location = str(request.POST['event-location']) event_description = str(request.POST['event-description']) event_start_date = str(request.POST['event-start-date']) event_start_time = str(request.POST['event-start-time']) event_end_date = str(request.POST['event-end-date']) event_end_time = str(request.POST['event-end-time']) creator = request.user … -
django 1.10, custom auth backend, is it ok to use just 1 custom backends?
I read it(Log in user using either email address or username in Django) and use this backend custom backend: from django.conf import settings from django.contrib.auth.models import User from django.contrib.auth.backends import ModelBackend class EmailOrUsernameModelBackend(ModelBackend): def authenticate(self, username=None, password=None): if '@' in username: kwargs = {'email': username} else: kwargs = {'username': username} try: user = User.objects.get(**kwargs) if user.check_password(password): return user except User.DoesNotExist: return None and settings.py: AUTHENTICATION_BACKENDS=[ 'logintest.custombackend.EmailOrUsernameModelBackend', ] Although it works well but I wonder whether I should use backend like this: AUTHENTICATION_BACKENDS=[ 'logintest.custombackend.EmailOrUsernameModelBackend', 'django.contrib.auth.backends.ModelBackend' ] Do I use it both backends? or It's ok for just one custom backend? -
Django can not import a local python package when runserver
I'm developing a simple django app, but I encounter an import issue.
