Django create unique function index
With postgresql we can create unique function index: create unique index user_date_checkin on unique_user_date (user_id, (timezone('UTC'::text, create_time)::date)); But with Django 3.2: class UserCheckin(GeneralModel): id = models.BigAutoField(primary_key=True) user_id = models.BigIntegerField() create_time = models.DateTimeField() class Meta: indexes = [ models.Index("user_id", TruncDate("create_time"), name="user_date_checkin"), ] can only got such sql generation: create index user_date_checkin on test (user_id, (timezone('UTC'::text, create_time)::date)); And UniqueConstraint constraints = [ models.UniqueConstraint( fields=["user_id", TruncDate("create_time")], name="user_date"), ] got refers to the nonexistent field 'TruncDate(F(create_time)) error So how can I create unique index with function in Django 3.2? -
Git bash "Watching for file changes with StatReloader" stuck and never loads
I have setup a Django project on a virtual environment on my PC. When using the command python manage.py runserver 0.0.0.0:8000 Bit Bash stops doing anything and I have to end the program to start over. I have waited several minutes and when I end the session, a dialogue says: Processes are running in session: WPID PID COMMAND 14904 1534 c:\Users\mine\AppData\Loca Close anyway? I have looked at every related question to this and tried every solution but I cannot get this to work, on or off the virtual environment. -
Showing unreserved times in frontend of django booking app
Im trying to build a booking app with Django. this is my "Event model" in my model.py: user = models.ForeignKey(User,null=True, on_delete=models.SET_NULL) date = models.DateField(null=True) time = models.TimeField(null=True) end_time = models.TimeField(null=True, blank=True) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) #date: Date the user want to come #time: The time the user want to come. #end_time: the time that the owner guesses for ending the job that user want time for it.

Updating a model when an object it references through a ManyToMany relation is deleted
I have a model, for instance class ModelA(models.Model): name = models.CharField() class ModelB(models.Model): last_modified_time = models.DateTimeField() as = models.ManyToManyField('ModelA') when I delete an instance of ModelA I would like to also update the last_modified_time field on all ModelB instances that referred to ModelA. I can use a predelete signal for this, i.e. def pre_delete_handler(sender=None, instance=None, *args, **kwargs): # update all using instance.modelbs... models.signals.pre_delete.connect(pre_delete_handler, sender=ModelA) but then every time a new model references it via a ManyToMany this bit of code needs to be updated which isn't the best from a maintenance point of view. I am looking for a way to enumerate all models that ModelA is referenced by so I can have a single update that covers all cases but can't figure out the best way to do this. What is the proper way to enumerate all objects that ModelA is related to? -

How to add get_queryset function in apiview of Djnago rest framework?
I am using Django APIView to include all my CRUD operation in a single api endpoint. But later on I had to use filtering logic based on the query parameters that have been passed. Hence I found it to include in a get api of APIView and made a separate api using generic view, ListAPiview. Here is the view: class LeadsView(APIView): permission_classes = [IsAuthenticated] def get(self, request, pk=None, *args, **kwargs): id = pk if id is not None: abc = Lead.objects.get(id=id) serializer = LeadSerializer(abc) return serializer.data def post(self,request,*args,**kwargs): abc = LeadSerializer(data=request.data,many=True) if abc.is_valid(): abc.save() return Response(abc.data, status=status.HTTP_201_CREATED) return Response(abc._errors, status=status.HTTP_400_BAD_REQUEST) def delete(self, request,pk, *args, **kwargs): Now, I have to use filter class and also some custom filtering logic, I need to use get_queryset. Hence I have to create another api just for get method which I dont want. class LeadAPIView(ListAPIView): authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) queryset = Lead.objects.all().order_by('-date_created') serializer_class = LeadSerializer filter_backends = [django_filters.rest_framework.DjangoFilterBackend] pagination_class = CustomPagination # filterset_fields = [ 'email','first_name','last_name','phone'] filterset_class = LeadsFilter def get_queryset(self): source = self.request.GET.get("source", None) # lead_status = self.request.GET.get("lead_status", None) if source is not None: source_values = source.split(",") if lead_status is not None: lead_status_values= lead_status.split(",") return Lead.objects.filter(source__in=source_values,lead_status__in=lead_status_values) else: return Lead.objects.filter(source__in=source_values) elif lead_status is … -

How to restore a dump database backup for a Django project with existing models and migrations?
Setting up a mysql database from an existing dump is very easy # open prompt cd into the directory where the dump is located # login to mysql create database mydb use mydb source mydb.sql And all is done! But the problem comes with Django. Django has troubles with existing schemes and data that have not been created from models and migration system. And in Django, everything must come from models and migrations. I perfectly know that I have this option python manage.py inspectdb > models.py But this is only suitable when creating a blank new Django project using existing database. What if I want to run an existing Django project to another machine and the Django project uses a database? The project already has existing models with some manage=false set, I cannot simply inspectdb it. And if I restore the database outside Django, the Django ORM will no longer recognize it. Then what is the correct way to restore a database from a database backup for a project with existing models and migrations? -

Django - Going back to a directory at a upper level from the template with href in django
trying to keep the question simple! I am currently in the directory which has a template cart.html: 8000/shop/cart/6/M/user and I want to go to the directory: 8000/shop/shirts So I just wrote in the cart.html: <a href="{% url 'shop' 'shirts' %}"> Which gives me an error: Reverse for 'shop' not found. 'shop' is not a valid view function or pattern name. So, I believe that its because I am trying to go from a lower directory back into a higher directory in the hierarchy so is there a way I can edit the href in cart.html in order to go to the shirts directory? Thanks in advance, -
How to iterate in subitems of a object in a django template
views.py: from django.views import generic from .models import Servico class ServicoView(generic.DetailView): model = Servico context_object_name = 'servico' template_name = 'servico.html' models.py: from djongo import models class PublicoAlvo(models.Model): def __str__(self): return '' alvo1 = models.CharField(max_length = 126) alvo2 = models.CharField(max_length = 126, blank = True, default = '') class Meta: abstract = True class Servico(models.Model): t_id = models.CharField(primary_key = True, unique = True, max_length = 252) alvos = models.EmbeddedField( model_container = PublicoAlvo ) urls.py: from django.urls import path from . import views urlpatterns = [ path('servicos/<slug:pk>/', views.ServicoView.as_view(), name = 'servico') ] I think these are the relevant files in my Django app folder. Back to the question, how can I iterate over the values that are going to be stored in servico.alvos in my template? If I want to show t_id, I just use {{ servico.t_id }} and it works fine. I could write something like: {{ servico.alvos.alvo1 }} {{ servico.alvos.alvo2 }} And that would show the values that I want, but that would make things uglier and more limited (imagine if I decide to change the model and add more 6 values in the PublicoAlvo class).
