Getting SUM for each unique fields in Django Query
I have the following table relations. I want SUM of total_cost from Sales_Transaction for each party_name from the Party table. The Parties have 1:M relation with Sales and Sales has 1:M relation with Sales_Transction. I tried this query but it returns the sum for all parties: Party.objects.aggregate(sales=Sum('sales__salestransaction__total_cost')) This is similar to this simple query: SalesTransaction.objects.aggregate(sales=Sum('total_cost')) I want output like this: | Party Name | Total Purchase | ----------------------------- |Party 1 | total_cost (calculated form Sales Transaction) |Party 2 | total_cost (calculated form Sales Transaction) How can I achieve these results in Django Query? -
admin change_view is being called twice
Is there a chance to keep django admin from calling change_view twice when clicking "save and continue editing"? class SomeAdmin(admin.ModelAdmin): form = SomeAdminForm def change_view(self, request, object_id, form_url = "", extra_context = None): extra_context = extra_context or {} print("test") return super().change_view(request, object_id, form_url, extra_context = extra_context,) prints test once, when entering the change form layout, prints test twice when clicking "save and continue editing". I run a costly query inside that change_view function, that needs to be displayed in the admin change form. But I want it to only run once. Any ideas? -

Is there any Pythonic way to manipulate Dictionaries to follow DRY philosophy in Django?
I have got dictionary set of required queries as shown below: [{'primary_attribute__name': 'Color', 'primary_attr_values__name': 'Red'}, {'primary_attribute__name': 'Color', 'primary_attr_values__name': 'Green'}] Now I want : [{'primary_attribute__name: 'Color', { 'primary_attr_values__name': 'Red', 'primary_attr_values__name': 'Green', 'primary_attr_values__name': 'Yellow' }] Or is this good approach: primary_attribute= { "Color" : {"primary_attr_values__name" : ["red", "green", "yellow"]} } How it can be achieved? -
How to configure redis 6 in django

Create Single Forms by Two Models in Django with Dynamic Fields
I want to create Django Forms to save transactions for the store. I want a final template similar to this. The ER Diagram for my database is also shown in the image. My Django Models are: class Party(models.Model): party_id = models.BigAutoField(primary_key=True) party_name = models.CharField(max_length=128) party_phone = models.CharField(max_length=128) party_address = models.CharField(max_length=128) def __str__(self): return self.party_name class Items(models.Model): item_no = models.BigAutoField(primary_key=True) item_type = models.BooleanField(default=True) item_name = models.CharField(max_length=128) item_qty = models.PositiveIntegerField(default=0) item_cost = models.PositiveIntegerField(default=0) def __str__(self): return self.item_name class Sales(models.Model): invoice_no = models.BigAutoField(primary_key=True) invoice_date = models.DateField(default=date.today) party = models.ForeignKey(Party, on_delete=models.CASCADE) def __str__(self): return str(self.invoice_no) class SalesTransaction(models.Model): sales = models.ForeignKey(Sales, on_delete=models.CASCADE) items = models.ForeignKey(Items, on_delete=models.CASCADE) purchase_qty = models.PositiveIntegerField(default=0) total_cost = models.PositiveIntegerField(default=0) def __str__(self): return self.item_name I can achieve this with AJAX but I don't think it is the best solution because lots of validations have to be made with hardcoding.

Django: Query .all() not hitting the database
THe django docs says: Returns a copy of the current QuerySet (or QuerySet subclass). This can be useful in situations where you might want to pass in either a model manager or a QuerySet and do further filtering on the result. After calling all() on either object, you’ll definitely have a QuerySet to work with. When a QuerySet is evaluated, it typically caches its results. If the data in the database might have changed since a QuerySet was evaluated, you can get updated results for the same query by calling all() on a previously evaluated QuerySet. I am using Django-Debug-Toolbar to optimize a query. If I have code like this (returning an empty list to ensure .all() is hitting the DB at this point in time: def get_querysets(): foo_list = Foo.objects.filter(...).all() bar_list = Bar.objects.filter(...).all() caz_list = Caz.objects.filter(...).all() return [] then Django debug toolbar won't register those queries, i.e. DB was not querried. However if I change it to: def get_querysets(): foo_list = Foo.objects.filter(...).all() bar_list = Bar.objects.filter(...).all() caz_list = Caz.objects.filter(...).all() print(foo_list) print(bar_list) print(caz_list) return [] Now in the toolbar I can see the queries. I know querysets are lazy, but the whole point of .all() is to make it hit the … -

Django forms: object has no attribute cleaned data

How to Nest URL routes in Django Rest Framework (DRF) RetrieveUpdateDestroyAPIView without router
I am using the Django rest framework and RetrieveUpdateDestroyAPIView and trying to Implement nested URL patterns. # my current URLs structure is like /api/v1/kitchens/ - ListCreateAPIView /api/v1/kitchens/1/ - RetrieveUpdateDestroyAPIView /api/v1/orders/ - ListCreateAPIView /api/v1/orders/1/ - RetrieveUpdateDestroyAPIView /api/v1/items/ - ListCreateAPIView /api/v1/items/1/ - RetrieveUpdateDestroyAPIView The above structure works fine with all the operations but to get the list of items or orders under a single kitchen I am trying to achieve something live below. the views.py has something like below. class KitchenListView(generics.ListCreateAPIView): queryset = Kitchen.objects.all() serializer_class = KitchenSerializer pagination_class = LimitOffsetPagination permission_classes = (permissions.IsAuthenticatedOrReadOnly,) authentication_classes = (TokenAuthentication,) filter_backends = (DjangoFilterBackend,) filter_fields = ("user",) class KitchenDetailView(generics.RetrieveUpdateDestroyAPIView): queryset = Kitchen.objects.all() serializer_class = KitchenDetailsSerializer permission_classes = ( permissions.IsAuthenticatedOrReadOnly, IsOwnerOrReadOnly, ) authentication_classes = (TokenAuthentication,) # I want to create this structure. /api/v1/kitchens/ - List /api/v1/kitchens/1/ - Details /api/v1/kitchens/1/orders/ - Orders List /api/v1/kitchens/1/orders/1/ - Order Details /api/v1/kitchens/1/items/ - Items List /api/v1/kitchens/1/items/1/ - Item Details I am trying to achieve something like this. Please suggest to me the better solution if anyone has and what would be better to go with generic API views or Viewsets as my project is a large-scale project. Thanks in Advance. -
