How to dynamically define and generate serializers in django
I am working on an event driven service which receives a lot of events and these events have payload. I want to validate all payloads with serializers. Since the events types and huge in numbers, I don't want to define serializers in code for every event as that would require a new release every time a new event is added or an existing one is changed. So, is there a way I can define these serializers dynamically for each event in a table instead of code and use it to validate the event payload ? Any new additions/changes can be done in the table itself. -
link MCO number to Reception number
I have a web page where the user is supposed to enter the reception number and the MCO number, so whatever reception number and MCO number is enter, it is supposed to be tag together like reception number: 123 and MCO number: 456, in the database it is supposed to show 123/456, how do I make it do that? This is how my webpage looks like (when the user click the submit button the reception number and the mco number will be tag together: But as shown in the picture below, the mco number will appear in another new row and not next to the reception number. views.py @login_required() def verifydetails(request): if request.method == 'POST': form = verifyForm(request.POST) if form.is_valid(): Datetime = datetime.now() status = 'Launching' mcoNum = form.cleaned_data['mcoNum'] if Photo.objects.filter(reception=form.cleaned_data['reception']): form = Photo(Datetime=Datetime, mcoNum=mcoNum, status=status) form.save() return redirect('ViewMCO') else: messages.success(request, 'The reception number you have enter is incorrect') return redirect('verifydetails') else: form = verifyForm() return render(request, 'verifydetails.html', {'form': form, }) forms.py class verifyForm(forms.Form): reception = forms.CharField(label='', widget=forms.TextInput( attrs={"class": 'form-control', 'placeholder': 'Enter Reception number'})) mcoNum = forms.CharField(label='', widget=forms.TextInput(attrs={"class": 'form-control', 'Placeholder': 'Enter MCO Number'})) class Meta: model = Photo fields = ("mcoNum", "status") ViewMCO.html {% extends "customerbase.html" %} {% block content … -
Django: Approach on how to realize IPC with other server/process
I have a Django App for user interaction which works perfectly fine. Now I want to have a communication channel with another primitive server a colleague of mine wrote. Probably will go for multiprocessing listeners via AF_UNIX. I don't know where to open a process that listens on the other servers messages and adds information to the database (also, I request information from the server but that shouldn't be much of a problem once the channel is open) Upon searching the web I found the suggestion to add a new command to the manage.py but I couldn't find out if I can execute two commands in parallel, also the GUI won't be executed as development server forever. If you have any suggestions on what tricks/technology/terms I should search for, I really appreciate the help! Still kind of a newbie to Django, so I might have missed something essential. -
How to add or remove objects in nested serializers Django using update function
I have 2 models - Module and Room. A module can have zero or multiple rooms and a room can be added into multiple modules. So, there is a simple many-to-many relationship between them. While updating the modules field using a put request, I don't want to update any rooms in it, I just want to add/remove rooms in the module. Here are my files - module/models.py - class Module(models.Model): module_id = models.AutoField(primary_key=True) title = models.CharField(max_length=100) desc = models.TextField() rooms = models.ManyToManyField(Rooms) rooms/models.py - class Rooms(models.Model): room_id = models.AutoField(primary_key=True) title = models.CharField(max_length=100) desc = models.TextField() level = models.CharField(max_length=100) is_deleted = models.BooleanField(default=False) module/serializers.py - class ModuleSerializer(serializers.ModelSerializer): rooms = RoomSerializer(read_only=True, many=True) class Meta: model = Module fields = "__all__" def create(self, validated_data): rooms_data = validated_data.pop('rooms') module = Module.objects.create(**validated_data) for data in rooms_data: room, created = Rooms.objects.get_or_create(**data) module.rooms.add(room) return module rooms/serialier.py - class RoomSerializerWrite(serializers.ModelSerializer): room_id = serializers.IntegerField() class Meta: model = Rooms fields = "__all__" module/views.py - class add_module(APIView): def post(self, request, format=None): module_serializer = ModuleSerializer(data=request.data) if module_serializer.is_valid(): module_serializer.save() return Response(module_serializer.data['module_id'], status = status.HTTP_201_CREATED) return Response(module_serializer.errors, status = status.HTTP_400_BAD_REQUEST) POST request body for updating a module in POSTMAN - { "module_id": 2, "rooms": [ { "room_id": 2, "title": "4", "desc": "22", "level": "2", … -
Django Rest Framework - Masking response values
I was wondering what the best way would be to mask a certain response parts. I will use an example to explain. Let's say I have a Person model with first_name, last_name and email. I use PersonSerializer to return that data. An example response can be { "first_name": "John", "last_name": "Doe", "email": "johndoe@gmail.com" } I want to "hide" an email when presenting it as response. I still want it to be present as the key, I just want to mask the value. So I want to achieve this response { "first_name": "John", "last_name": "Doe", "email": "__MSK__" // so it get's masked } So this should not impact the serialization when creating a new patient with same serializer class as well. Anyone has idea what the best way would be? Maybe overriding to_representation method or? -
Django: filter the logs which are coming from the front end
I had implemented the logging in my Django project, at Debug level. There is a whole lot of information coming to logger which make my system hang up.

Django - Have function inside of a view function automatically return a response to user if error?
So I have this post request below that gets a video upload then validates it. I'd ideally like validate_video_upload() to return a 400 response if the video is larger than the allowed size rather than raise a validation error, because I'd like to notify the user that the video is too large. How do I set it up so that if validate_video_upload() returns a Response, it'll just return the call with the status and message, if there's no response returned then it just proceeds normally? View.py def post(self, request): if 'video' in request.FILES.keys(): vid = request.FILES.get('video') validate_video_upload(vid) function.py def validate_video_upload(file): if not is_valid_file_of_format(file._name, VALID_VIDEO_EXTENSIONS): raise ValidationError("Video file format is invalid") if file.size>2296000000: raise ValidationError("Maximum size allowed for a video is 287 mb") -
Invoking Django-river manually for workflow management
Our application uses Django_river for workflow management. And currently, the river is being invoked based on the post save signal created by Django. But for performance-related issues, we had to use the bulk option for inserting data that does not support signals by default. We have generated signals manually, but this is slowing down our system. Is there any way to manually invoke the river from our code based on the business conditions? -
Django apps communication in abstraction layer
We are starting a new Django project which will consist of many different applications inside it. At first I was thinking of looking at some of these applications as individual services but department heads told us that at this stage we do not need scaling, distributing and balancing, so just keep them inside the same project. However, I was also asked to keep my design clean and move application communications into an abstract layer. So the idea is to have a well defined interface for each service (django apps), and in order for services to talk to each other they will read the implementation of these interfaces from a factory and call the methods. All sounded good to me till I was starting to implement this. I was told that one day we may extract these django apps and put them in a different project and run them in multiple machines so we can distribute and balance the load between them. So I have had to find an implementation of the "well defined interface" which would be very easy to change when applications get extracted from the project. Approach A I could not come up with a lot of ideas … -

Django filter ListViews
I am still rookie.. This is my first experience with CBV. My goal is to create one template with list that i can filter by my models field, like Date, Category, and more. My first try was to create more than one ListView, each for category but it's just doesn't look and feel right and I can't find anything to solve that on Google or django documentation..

Django Rest Framework, group_by queries using .values(), and embedding a related record
I can't figure out how to embed a related record into a Django Rest Framework response when using .values() on a Django query set to return grouped by aggregated values. Sample Models, Serializers, and Viewset included below along with current response and a sample desired response. Each Trade has one security. Multiple trades can exist for a security. I have a need to display Trades individually and also grouped by security. When grouping by security, I want to return the embedded security in the response along with the aggregate values for the associated trades, but so far I can only get the security id returned.
