Join with OneToOneField relathionship django
I have two models with OneToOneField relationship and I want to somehow join them and be able to access the attribute of the one model from the other. My models.py is as follows: from django.db import models from django.contrib.postgres.fields import ArrayField from django.contrib.auth import get_user_model CustomUser = get_user_model() class Event(models.Model): user_id_event = models.ForeignKey(CustomUser, on_delete=models.CASCADE, null=True) created_at = models.DateTimeField(auto_now_add=True, null=True) dr_notice_period = models.IntegerField(blank=True, null=True) dr_duration = models.IntegerField(blank=True, null=True) dr_request = models.FloatField(blank=True, null=True) class Result(models.Model): event_id_result = models.OneToOneField(Event, on_delete=models.CASCADE, null=True) HVAC_flex = ArrayField(models.FloatField(blank=True, null=True)) DHW_flex = ArrayField(models.FloatField(blank=True, null=True)) lights_flex = ArrayField(models.FloatField(blank=True, null=True)) My views.py is as follows: @api_view(['GET']) def result(request): results_list = Result.objects.all() num_results_list = Result.objects.all().count() if num_results_list < RES_LIMIT: serializer = ResultSerializer(results_list, many=True) query = serializer.data return Response(query) else: results_list = Result.objects.order_by('-created_at')[:RES_LIMIT] serializer = ResultSerializer(results_list, many=True) query = serializer.data return Response(query) Right now the query is as follows: [OrderedDict([('id', 1), ('HVAC_flex', [49.0, 27.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]), ('DHW_flex', [4.0, 0.0, 45.0, 4.0, 20.0, 33.0, 42.0, 13.0]), ('lights_flex', [6.0, 8.0, 0.0, 0.0, 0.0, 18.0, 28.0, 0.0]), ('event_id_result', None)]), OrderedDict([('id', 2), ('HVAC_flex', [0.0, 0.0, 15.0, 0.0, 23.0, 6.0, 0.0, 0.0]), ('DHW_flex', [1.0, 2.0, 7.0, 47.0, 1.0, 19.0, 37.0, 9.0]), ('lights_flex', [40.0, 28.0, 34.0, 6.0, 8.0, 43.0, 6.0, 0.0]), ('event_id_result', None)]), OrderedDict([('id', … -
Django admin - admin inheritance
When registering django admin, I inherited another admin, but I don't know why the model of list_display is changed. Let me explain the situation in detail with code. @admin.register(User) class UserAdmin(models.Model): list_display = [a.name for a in User._meta.concrete_fields] @admin.register(Sales) class SalesAdmin(UserAdmin): pass According to the code above, SalesAdmin Admin appears to inherit from UserAdmin. In this case, shouldn't list_display of User model appear in list_display? I don't understand why the list_display of Sales Model comes out. If I want to display the list_display of the Sales model while inheriting UserAdmin, shouldn't I have to redeclare the list_display as shown below? @admin.register(User) class UserAdmin(models.Model): list_display = [a.name for a in User._meta.concrete_fields] @admin.register(Sales) class SalesAdmin(UserAdmin): list_display = [a.name for a in Sales._meta.concrete_fields] I did not redeclare list_display, but I do not understand whether it is automatically output as the list_display of the changed model. If anyone knows, please explain. -

Querying within a list of dicts within a Django model JSONField
I'm trying to query an element within a list of dicts in a Django JSONField. I can find similar questions to mine but not one that covers what I'm trying to do. It seems like it should be simple and fairly common so I suspect I'm missing something simple. So. to expand slightly on the example in the Django docs Let's say I have a Dog model with a JSONField named data and it has some data like so: Dog.objects.create(name='Rufus', data = {"other_pets": [{"name", "Fishy"}, {"name": "Rover"}, {"name": "Dave"}]} ) There's a key named "other_pets" which is a list of dicts. I would like to write a query which returns any models which includes a dict with the key name=="Dave" I am able to directly do this if I refer to the element by the index, eg: Dog.objects.filter(data__other_pets__2="Dave") Would return me the row, but I need to reference the index of the list element, and both the position of the item I'm looking up, and the size of the list vary among models. I thought that maybe: Dog.objects.filter(data__other_pets__contains={"name":"Dave"}) Would work but this returns no elements. Is what I'm trying to do possible? As an aside, is it possible to add … -

How can I sort instances by a fk related field in a serializer in Django?
According to a prior answer to one of my questions I am trying to re-arrange the queryset qs_payments of objects by field month utilising their fk relationship. The statement in my prior enquiry was you can just serialize the Payments on each Month directly But how would I basically achieve this? As far as I understand I have to use the serializer for the months model then and tell it to sort the qs by month? # models.py class Period(models.Model): period = models.DateField() class Payment(models.Model): offer = models.ForeignKey(Offer, on_delete=models.CASCADE) month = models.ForeignKey(Period, on_delete=models.CASCADE) amount = models.PositiveIntegerField() # serializers.py class PaymentSerializer(serializers.ModelSerializer): class Meta: model = Payment fields = '__all__' class PeriodSerializer(serializers.ModelSerializer): class Meta: model = Period fields = '__all__' class PayrollRun(APIView): def get(self, request): # Get the related company according to the logged in user company = Company.objects.get(userprofile__user=request.user) # Get a queryset of payments that relate to the company and are not older than XX days qs_payments = Payment.objects.filter(offer__company=company) print(qs_payments) serializer = PaymentSerializer(qs_payments, many=True) return Response(serializer.data) The desired output is that I want to map each month to a React component containing all line items of that particular month. So I need (at least imho) a dictionary of months each having … -

JWT Cookie sent as Set-Cookie causing "Invalid Signature" in DRF jwt
I've been trying to solve this problem a week ago, from now on after looking for a solution in almost every forum, blog and lib's github issues I realized that it gonna be easier asking here. I have a django app using JWT for authentication (Web and Mobile), when I change the user email the mobile app (react native) keeps sending the old jwt in cookies to server which leads to an "Invalid Signature" response (in any endpoint including login) Here is my djangorestframework-jwt conf: JWT_AUTH = { 'JWT_VERIFY_EXPIRATION': True, 'JWT_AUTH_COOKIE': "JWT", 'JWT_EXPIRATION_DELTA': datetime.timedelta(seconds=3000), 'JWT_ALLOW_REFRESH': True, } Setting this line 'JWT_AUTH_COOKIE': "JWT", To 'JWT_AUTH_COOKIE': None, The server won't look for jwt cookies in request however the next api calls don't find token in Authorization Header which leads to Authentication credentials were not provided Even sending the token in Header. At web app there is no problem with that, so I'd like to know how can I fix it, looking for a way to stop sending JWT cookie from mobile app. -
Django silently removes constraints when removing columns, then arbitrarily choses to include them in migrations
I’ve encountered an odd bug(?) in Django in our production code. Dropping a column manually in migrations without removing its constraints leads to Django being unaware those constraints have been removed, and auto-generating incorrect migrations. A short example: Creating the migrations for this schema: class M(): a = models.IntegerField(default=1) b = models.IntegerField(default=2) class Meta: constraints = [ UniqueConstraint( name="uniq_ab_1”, fields=[“a”, “b”] ) ] Create the constraint uniq_ab_1 is Postgres as expected (when using the \d+ command on the table to visualise) However, this manual migration will remove the constraint, due to one of it’s member columns being deleted, this is just standard Postgres behavior: migrations.RemoveField( model_name=“m”, name=“a”, ), migrations.AddField( model_name=“m”, name=“a”, field=models.IntegerField(default=6), ), This migration runs just fine. I can even modify the field of M again and run a further migration. However, using \d+ reveals that the uniq_ab_1 constraint` is gone from the database. The only way I found out about this behaviour was renaming the constraint to uniq_ab_2, then auto-generating migrations and getting the error: django.db.utils.ProgrammingError: constraint "uniq_ab_1" of relation … does not exist. In other words, on a rename, Django become aware a rename was happening and tried to remove the constraint from the database, in spite … -

Django Sessions - Pass data between views
I am trying to use Django sessions to pass data between separate views when completing a booking submission.

Apologies since this might not be the best way to word the question nor is this a coding question per say. I get the general process of creating a staff user within Django. What I would like to know is if companies send email links that allow their workers to sign up a form to be a staff user or if the employer provides their details and someone on the backend creates this account for them, or some other process I am unaware of? -
Django Authorization Checking in URL having wild card pattern
I am trying to implement permission checking mechanism in URLs for a request using wildcard techniques, rather than implement permission checking on each views. Currently What I have is. urlpatterns = [ path('admin/', include('admin_urls.py')), ... ] and my admin_urls.py is as follows urlpatterns = [ path('', ViewSpaceIndex.as_view(), name="admin_index"), path('', EmployeeView.as_view(), name="employee"), ... ] and views are as follows @method_decorator(admin_required, name='dispatch') class EmployeeView(TemplateView): template_name = 'secret.html' @method_decorator(admin_required, name='dispatch') class EmployeeView(TemplateView): template_name = 'secret.html' What I want to achieve is without using the repeated @method_decorator(admin_required, name='dispatch') decorator in every view I want to apply the permission to a wild card URLs '/admin/**' with admin_required permission like in Spring boot as follows. http.authorizeRequests() .antMatchers("/admin/**").has_permission("is_admin") -
Django: how to sum up numbers in django
i want to calculate the total sales and display the total price, i dont know how to write the function to do this. I have tried writing a little function to do it in models.py but it working as expected. This is what i want, i have a model named UserCourse which stored all the purchased courses, now i want to calculate and sum up all the price of a single course that was sold. models.py class Course(models.Model): course_title = models.CharField(max_length=10000) slug = models.SlugField(unique=True) price = models.IntegerField(default=0) class UserCourse(models.Model): user = models.ForeignKey(User , null = False , on_delete=models.CASCADE) course = models.ForeignKey(Course , null = False , on_delete=models.CASCADE) date = models.DateTimeField(auto_now_add=True) and also how do i filter this models in views.py so i can display the total price of courses a particular creator have sold.
