(django) how to flatten an array inside of a dictionary to an array only
I am currently trying to handle the nested data in django. In my case, I want to remove the key "event_log" and flatten it to a simple array of dictionary only. { "event_log": [ { "date": 12-12-2000, "point": 500 }, { "date": 12-12-2001, "point": 700 } ] } The outcome should look like this: [ { "date": 12-12-2000, "point": 500 }, { "date": 12-12-2001, "point": 700 } ] I have tried adding a to_representation method to the serializer: class EventDateSerializer(serializers.ModelSerializer): event_log = EventLogSerializer(many=True, read_only=True) class Meta: model = EventDate fields = ['event_log'] def to_representation(self, instance): data = super().to_representation(instance) flatten_data = data['event_log'] for item in flatten_data: for key, value in item.items(): data[key] = value return data However, it turns out this method can only flatten nested dictionary instead of array inside of dictionary. Has anyone got an idea on how to flatten the array inside of the dictionary? Much appreciated. -

Want to access a file which is in another docker container from anotherdocker container using python code
We have two docker containers. The first container is backend_device_service which we access using the command -> docker exec -it backend_device_service bash. On this backend_device_container we write our python code. Now I am writing an API which needs to access a file which is on another container rsyslog (server is same just the container is different). We access this container using the command -> docker exec -it rsyslog bash In this container at the path -> /var/log/CPE my file contains which I need to access. However I can access any path in the same container using the following piece of code:- class SysLogReader(APIView): authentication_classes = [JWTAuthentication] permission_classes = [IsAuthenticated] def get(self, request): content = os.popen('cat /app/sdwan_device_service/devices/views').read().strip('\n').lower() logger.info(f"\ncontent of the file:\n {content}\n") dir_path = os.path.dirname(os.path.realpath(__file__)) resp = {"success":True, "message" : f"Directoty path is {dir_path}"} return Response(resp, status=status.HTTP_200_OK) While my problem is how to access the file which is in another container rsyslog. -

How to filter django queryset based on the serializer field value?
serializer class MyModelSerializer(serailizers.ModelSerializer): hrs = serializers.SerializerMethodField() get_hrs(self, obj): datetime = SomeModel.objects.filter(id=obj.id).last().datetime now = datetime.now() return (now - datetime).total_seconds() // 3600 class Meta: model = MyModel fields = "__all__" Now in the api there will be a filter paramter hr what it need to do is filter the queryset matching this above calculated hr. For example: @api_view(["GET"]) def get_list(request): qs = MyModel.objects.all() hr = request.GET.get("hr") if hr: qs = qs.filter(hrs=hr) # hrs is not inside model return MyModelSerializer(qs, many=True).data Here hrs is not there inside the Model it's a serializer field above calculated. How can I filter like this from serialzier fields ? Any gudiance would be very helpful. -
Why does changing my render request in views.py break my ability to import images in my base.html?
In my views.py, I have a function for my homepage; @login_required(login_url="/login") def home(request): user_object = User.objects.get(username=request.user.username) user_profile = Profile.objects.get(user=user_object) posts = Post.objects.all() return render(request, "main/home.html", {'user_profile': user_profile}) #This is the problem line and my HTML runs perfectly; <body> <header> <div class="container"> <img src="{% static 'css/images/uReflect.png' %}" alt="logo" class="logo"> <nav> But when I change my home function in views.py to the code below, my page stops working. I have no idea how an error with 'post.image' would correlate to me accessing my images that are independent of posts, and exist in a separate folder. The weirdest part to me is how the error says "NoReverseMatch at /home" but the error doesn't even occur in home.html, it occurs in base.html. Although, home.html does extend base.html; @login_required(login_url="/login") def home(request): user_object = User.objects.get(username=request.user.username) user_profile = Profile.objects.get(user=user_object) posts = Post.objects.all() return render(request, "main/home.html", {'user_profile': user_profile, 'posts': posts}) # Change made here with posts -
Django: query filter
I have two models that are related: one is a list of participants. The other is a list of times they have checked in or out of an office. The table (Checkin) has one record for every checkin/checkout pair. So, there can be many records for any participant. How can I retrieve only the very last (most recent) record for a participants checkin and then pass the participant and only that most recent Checkin record to my template? From what I can tell there's no ability to do something like a last() in my template, so how would I go about filtering to get just that single record? Thank you. Models: class Participant(models.Model): first_name = models.CharField(max_length=50) middle_initial = models.CharField(max_length=50, blank=True) class CheckIn(models.Model): adult = models.ForeignKey( Participant, on_delete=models.CASCADE, blank=True, null=True, related_name='adult_checkin') checkin = models.DateTimeField(blank=True, null=True) checkout = models.DateTimeField(blank=True, null=True) View snipit: p_checkins = Participant.objects.all().order_by('created') queryset = p_checkins context_object_name = "the_list" template_name = 'list_of_checkins.html' -
