how can i get queryset based on mapping table in django rest framework?

Making a request that triggers a function that searches a json object. The object will be updated every minute, could this lead to issues?
I am making a bus prediction web application for a college project. The application will use GTFS-R data, which is essentially a transit delay API that is updated regularly. In my application, I plan to use a cron job and python script to make regular get requests and write the response to a JSON file, essentially creating a feed of transit updates. I have set up a get request, where the user inputs trip data that will be searched against the feed to determine if there are transit delays associated with their specific trip. My question is - if the user sends a request at the same time as the JSON file is being updated, could this lead to issues? One solution I was thinking of is having an intermediary JSON file, which when fully loaded will replace the file used in the search function. I am not sure if this is a good solution or if it is even needed. I am also not sure of the semantics needed to search for solutions to similar problems so pointers in the right direction would be useful. -

How to return 400 status code from custom middleware in django?
I am trying to write a custom middleware which does some operation on the request to check its validity and if the request is invalid then return the bad request 400 status code without even going ahead. from django.http import HttpResponseBadRequest class VersionCheckMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): meta = request.META client = meta.get('HTTP_X_APP_CLIENT', None) if client == 'ios': app_version = ( int(meta['HTTP_X_IOS_APP_VERSION']) if meta.get('HTTP_X_IOS_APP_VERSION') else int(meta.get('HTTP_X_APP_VERSION', 0)) ) if app_version < 30: return HttpResponseBadRequest elif client == 'android': app_version = int(meta['HTTP_X_APP_VERSION']) if app_version < 188: return HttpResponseBadRequest elif client == 'web': app_version = int( meta['HTTP_X_APP_PLATFORM_VERSION'] if meta.get("HTTP_X_APP_PLATFORM_VERSION") else meta['HTTP_X_APP_VERSION'] ) if app_version < 188: return HttpResponseBadRequest response = self.get_response(request) return response -
how to add value from user input field in django imoirt-export library?
I have model named Product and Calculator that is connected to each item in Product model. What I am trying to achieve is to allow user to insert number of units and based on this number calculate total price in Excel file that will be exported when user clicks Calculate button. Questions: How can I add value inserted by a user in my input field to my cost_calculator.xlsx file and based on that value calculate total price? How can I add unit_hours property from CostCalculator model to my exported file? I successfully added it to admin page and it shows me correct result but when I add to to fields in my resource model then I get KeyError. What is the best approach to calculate total_price and display it in Excel in my case? The formula is following: number_of_units * rate * margin = total_price. Should I put it in form_valid in ProductDetailView or in ExportData view or maybe I shouldn't seperate Export button to seperate view but add it to form_valid. Is it possible to merge Send and Calculate buttons into one so if user clicks 1 button it will send user's value, calculate and export unit_hours and total_price … -
How do I change the default value of a field on a bound form that gets rendered in Django?
In a Django project we have forms that have already been submitted where for some reason the person before me set the default value of a field to be one blank space (' ') and this is affecting some other functionality where we need to copy data (not relevant to go into detail for this question I don't think) Anyway, here is a snippet from models.py where I changed the default value to '': #inside class Meta base64_encoded_activation_key = models.CharField (max_length = 1000, default = '', blank = True, verbose_name = 'Activation Key') Inside views.py def edit_activation(request, id=None): ...... activation = get_object_or_404(ActivationRecord, pk=id) ....... ....... ....... else: # GET request form = ActivationRecordForm(instance=activation) Now, this works fine if I create and submit a new form, but when I go back to an old form then the value is still ' ' (which I guess is expected as the form has been submitted) but I don't know how to fix this to the new default value. -

how to filter number of posts per page in Django python

Check overlapping reservation
I am developing a Reservation System in Django. I have a booking model, and in views the logic to make new booking and also to edit bookings. The logic in creating new bookings works perfectly but I am having problems when editing it. Basically, what I need to achieve is: If I edit my reservation but I don't change any data, I want the form to be saved If I edit my reservation and I change some data, I want the form to be saved ONLY if it doesn't overlap with any other reservation. I post some code: models.py class Booking(models.Model): aircraft = models.ForeignKey(Aircraft, on_delete=models.CASCADE) student = models.ForeignKey( Student, on_delete=models.CASCADE, blank=True, null=True) instructor = models.ForeignKey( Instructor, on_delete=models.CASCADE, blank=True, null=True) renter = models.ForeignKey( Renter, on_delete=models.CASCADE, blank=True, null=True) booking_date = models.DateField() start_time = models.TimeField() end_time = models.TimeField() uid = models.CharField(max_length=200, null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) The uid field I created is a sort of logic to have a kind of Unique ID of the reservation in order to check if anything changed when I edit the booking. views.py if request.method == "POST": aircraft = request.POST.get('aircraft') student = request.POST.get('student') instructor = request.POST.get('instructor') renter = request.POST.get('renter') date = request.POST.get('date') start_time = … -
How to add/update objects using serializers in the Django Rest Framework?
I am using Django Rest Framework so that my other Django project can change records in this project's database, and am using serializers to do so. I am using the .save() method, which will add to the database only if none of the existing records share the same primary key as the ones being saved. I would like to "update" these existing records, either by updating them straight or deleting them then creating them again. This is my views.py: from rest_framework.response import Response from rest_framework.decorators import api_view from .serializers import parcelSerialiser @api_view(['POST']) def addItem(request): serializer = parcelSerialiser(data=request.data, many = True) print(request.data) print(serializer.is_valid()) print(serializer.errors) if serializer.is_valid(): serializer.save() return Response(serializer.data) and my serializers.py: from rest_framework import serializers from mainMenu.checkIn.models import Parcels class parcelSerialiser(serializers.ModelSerializer): class Meta: model = Parcels fields = '__all__' -

passing session in forms.py in django
I'm working on django project, in which I'm using model as form to generate an image upload page. The problem is there's a foreign key referring to user's profile table which fetches a list of users in a drop down menu. I figured i need to use the session value from logged in user but so far I haven't been able to pass the session through forms.

Best way to convert Django ORM query to GraphQL
So I have this webapp, that the frontend side allows the user to build dashboards which in-turn create a GraphQL query. This query is sent the the Backend (Django) and all the backend does is route this request to some external DB that handles the GraphQL and returns a response. The issue: I have a complex logic in the backend, that knows how to create a Django ORM query (Q) per each request, which I would like to combine with the GraphQL query. Basically im trying to convert a Django Q (django.db.models.query_utils.Q) into a GraphQL filter section. Is there a way to do it? Maybe with a different generic lang than GraphQL? or Do I have to resort to write something myself -
Submitting Bulk Forms In Django
I have 5 different forms in forms.py; the forms are all based off of 1 model. The 5 forms are all displayed on the same html page, so as to allow the user to create or register 5 objects into the DB with 1 single button click. In the future, I might need to submit 50 forms in a single click. If I were to do this based on the existing code, I would probably need 50 forms in forms.py and repeat the registration logic in views.py for 50 times. Is there a more efficient way to do this? views.py def register(request): form1 = DetailsForm1() form2 = DetailsForm2() form3 = DetailsForm3() form4 = DetailsForm4() form5 = DetailsForm5() if request.method == "POST": form1 = DetailsForm1(request.POST) if form1.is_valid(): form1.save() form2 = DetailsForm2(request.POST) if form2.is_valid(): form2.save() form3 = DetailsForm3(request.POST) if form3.is_valid(): form3.save() form4 = DetailsForm3(request.POST) if form3.is_valid(): form3.save() form5 = DetailsForm5(request.POST) if form5.is_valid(): form5.save() return render(request, "app/registration_completed.html") context = { "form1": form1, "form2": form2, "form3": form3, "form4": form4, "form5": form5 } return render(request, "app/register.html", context) forms.py class DetailsForm1(forms.ModelForm): class Meta: model = Property fields = ( 'owner', 'address', 'postcode', ) class DetailsForm2(forms.ModelForm): class Meta: model = Property fields = ( 'owner', 'address', 'postcode', … -
Web API that itself sends data to client on availability
I am currently working with Django but I am stuck as I don't know if I am pursuing the right model given the nature of my application. Problem Statement: I have to make a REST API for a client such that whenever I get a trigger for a new entry/entries in my Database I have to send those to the client which is supposed to listen to a URL and has asked for data only once and now is open to receive data whenever available to him. It is not sending a GET request now and then. There will be different endpoints of the APIs. One is where I provide him all the new data available to me and in other where it asks for specific data (ex: '/myAPI/givemethis') I can easily implement the second requirement as it is a simple request-response case. I am not sure how to send him data that too on availability without him making a repeated request as client. It appears a Publisher-Subscriber model is better suited for my use case but I don't know how to implement it on Django. I bumped into several concepts like StreamingServices and MQTT but I am not sure … -
