Django annotation using data from another table without relations
What I'm trying to do is annotate a queryset with information from a few tables that don't have foreign key relations between them, but can be identified from values in the main table. I realise that I could add relations and do something like this, but the db I'm using doesn't allow for relations. So given models: class DailyShopData(models.Model): shop_id = models.IntegerField() currency = models.CharField() date = models.DateField() amount = models.IntegerField() class Meta: unique_together = ('shop_id', 'date', 'currency') class DailyUserData(models.Model): shop_id = models.IntegerField() currency = models.CharField() date = models.DateField() unique_users = models.IntegerField() class Meta: unique_together = ('shop_id', 'date', 'currency') We can relate the two fields via the ('shop_id', 'data_date', 'currency') key. So what I'd like to do for my annotation is: DailyShopData.objects.values('shop_id').annotate( shop_amount=Sum("amount"), shop_unique_users=Sum(???) ) So that the result would be aggregated amount and unique_users per shop_id. -
Django RF + React JS, How to check in frontend whether any user is being logged in?
I use Django Rest Framework in backend and React in frontend for my Blog project. In Django templates if we use {{user}} method, we will know if anybody being logged in. But I am unable to use the above method in React JS environment. Should I send a test create (POST) request to server to check that ? Any better idea ? -
Django - multiple form choice field values not saving in model correctly
I am new to Django and have a ChoiceField form which I am using multiple times on the same html page. I have successfully saved all these values to the database. However, the values are saving incorrectly. If the choices are different on each form, they are saved in the table as the first value (APPLE). If the choices are all APPLE or all ORANGE they save correctly. But if they are mixed they don't save properly. Any ideas on what is happening here or how to fix the issue? Please see Form, View and HTML below. FORM: FRUIT = ( ("APPLE", "APPLE"), ("ORANGE", "ORANGE"), ) class SubmitFruitForm(forms.ModelForm): preference = forms.ChoiceField(choices=FRUIT, required=False, label= '') class Meta: model = user_choice fields = ('preference',) VIEW: class SubmitFruitView(TemplateView): template_name = 'accounts/fruit.html' def get(self, request): form1 = SubmitFruitForm() form2 = SubmitFruitForm() form3 = SubmitFruitForm() return render(request, self.template_name, {'form1': form1, 'form2': form2, 'form3': form3}) def post(self, request): form1 = SubmitFruitForm(request.POST) form2 = SubmitFruitForm(request.POST) form3 = SubmitFruitForm(request.POST) if form1.is_valid(): post = form1.save(commit=False) post.user = request.user post.save() if form2.is_valid(): post = form2.save(commit=False) post.user = request.user post.save() if form3.is_valid(): post = form3.save(commit=False) post.user = request.user post.save() return redirect('home') args = { 'form1': form1, 'form2': form2, 'form3': form3, } … -

Django-allauth reloads page twice after LOGIN_REDIRECT
I am using Django-allauth for user registration with social networks. Either with Google or with Facebook, when the login is performed, I see how my index page is reloaded twice. My allauth settings: SOCIALACCOUNT_PROVIDERS = \ { 'facebook': {'METHOD': 'oauth2', 'SCOPE': ['email', 'public_profile'], 'AUTH_PARAMS': {'auth_type': 'rerequest'}, 'FIELDS': [ 'id', 'email', 'name', 'first_name', 'last_name', 'verified', 'locale', 'timezone', 'link', 'gender', 'updated_time'], 'EXCHANGE_TOKEN': True, 'LOCALE_FUNC': lambda request: 'path.to.callable', 'VERIFIED_EMAIL': False, 'VERSION': 'v2.4'}, 'google': { 'SCOPE': ['https://www.googleapis.com/auth/userinfo.profile', 'https://www.googleapis.com/auth/userinfo.email'], 'AUTH_PARAMS': {'access_type': 'online'}, } } ACCOUNT_EMAIL_VERIFICATION = 'none' My other settings which might be relevant: LOGIN_URL = "/login/" LOGIN_REDIRECT_URL = "/" LOGOUT_REDIRECT_URL = '/' I have tried using an account adapter and redirecting to another URL, but I always see this target page reloaded twice. Any ideas how to avoid this behaviour? -

Redirect to a specific private page with LoginRequiredMixin after login
When trying to access a private page, this view redirects to the login page if the user is not authenticated, and after the authentication was done, I wanted it to redirect to the private page instead of success_url, with LoginView configured for a FormView. When I access the private page without logging in, this standard url is generated according to django http://localhost/myapp/login/?next=/myapp/private-page/, in this case the url that will be redirected after login should be myapp/private-page instead of success_url My code looks like this: # myapp/urls from django.urls import path from . import views app_name = 'myapp' urlpatterns = [ path("", views.home, name='home'), path("login/", views.LoginRequest.as_view(), name='login'), path('logout/', views.logout_request, name='logout'), path("signup/", views.signup, name='signup'), path("private-page/", views.PrivatePage.as_view()), ] # myapp/views.py class PrivatePage(LoginRequiredMixin, TemplateView): template_name = 'myapp/private-page.html' login_url = 'myapp:login' class LoginRequest(FormView): template_name = 'myapp/auth/login/login.html' form_class = LoginForm success_url = 'myapp:home' def form_valid(self, form): """If the form is valid, redirect to the supplied URL.""" username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') user = authenticate(username=username, password=password) if user is not None: login(self.request, user) messages.info(self.request, f'You are connected as {username}') # here the code to redirect to the private-page # instead this return return redirect(self.get_success_url()) else: self.form_invalid(form) def form_invalid(self, form): """If the form is invalid, render the … -

Why are some Elastic Search records disappearing
I have a Django application using ElasticSearch (via django-elasticsearch-dsl==7.1.1) and I have certain records that are disappearing from my searches (ie they show one day but not the next).

Django ORM: Raw query behaves different from ORM query
I'm having an issue and i can't even figure out what's the problem. I'm trying to obtain the result with the following expression using Django ORM: # Names of the models and fields are different from those on the DB. >>> readings = MeterReading.objects.annotate(plant_id=F('meter__metertypeidentifier__plant')) \ .filter(datetime__range=(datetime.datetime(2020,1,1,12),datetime.datetime(2020,1,1,16)), plant_id=2) \ .annotate(date_hour=Trunc('datetime', 'hour')) \ .values('meter', 'date_hour', 'plant_id') \ .annotate(energy_sum=Sum('energy') This expression produces this result: >>> <QuerySet [{'meter': 8, 'plant_id': 2, 'date_hour': datetime.datetime(2020, 1, 1, 12, 0, tzinfo=<UTC>), 'energy_sum': 2253.1499999999996}, {'meter': 31, 'plant_id': 2, 'date_hour': datetime.datetime(2020, 1, 1, 12, 0, tzinfo=<UTC>), 'energy_sum': 3117.9879999999994}, {'meter': 9, 'plant_id': 2, 'date_hour': datetime.datetime(2020, 1, 1, 12, 0, tzinfo=<UTC>), 'energy_sum': 1171.7999999999997}, {'meter': 10, 'plant_id': 2, 'date_hour': datetime.datetime(2020, 1, 1, 12, 0, tzinfo=<UTC>), 'energy_sum': 2441.4749999999995}]> which is not what I expect (the expected result is reported in the table below as the result of the mysql query).
