How to Filter value of model Field based on other model field value in django?
I have a model: class Employee(models.Model): name = models.CharField(max_length=128) nic = models.CharField(max_length=25, unique=True) def __str__(self) -> str: return self.name class Team(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField("Employee") def __str__(self) -> str: return self.name class Standup(models.Model): team = models.ForeignKey("Team", on_delete=models.CASCADE) employee = models.ForeignKey("Employee", on_delete=models.CASCADE) work_done = models.DateTimeField(auto_now=True) This is the ViewSet: class StandupViewSet(ModelViewSet): serializer_class = serializers.StandupSerializer queryset = Standup.objects.all() Now when I hit the API to post the data of standup, Standup.employee should display only those employees which are in a particular meeting, it should not display all the employees. Information about a particular team will be retrieved from Standup.team, and Standup.employee should display these employees: Standup.team.members. We will select one employee from the subset of employee list, instead of selecting employee from all the employees. It can be changed dynamically based on the value of Standup.team. Please guide. -

Complete Error: Creating test database for alias 'default'... Got an error creating the test database: duplicate key value violates unique constraint "pg_database_datname_index" DETAIL: Key (datname)=(test_chat_app) already exists. I added the pre commit hook in Python-Django to run testcases before commit. It is working fine on my side, but when my collegues trying to commit, the above error occurs.

File upload using Django Post method
I'm trying to post a file from remote server to client server. This can be a large file sometime upto 20k lines. And then store it in the client server for further processing using pandas. Example file.txt: A*B*C* D*E*F* G*H*I* I was able to do the file transfer using the below snippet in my views.py class FileUploadView(APIView): parser_classes = (FileUploadParser, ) def post(self, request, format=None): up_file = request.FILES['file'] destination = open('/home/xxx/' + up_file.name, 'wb+') for row in up_file.chunks(): destination.write(row) destination.close() return Response(up_file.name, status.HTTP_201_CREATED) But then again, the file seems to be in binary format for the obvious reasons that the file open mode was binary.. and at the same time when i open the file all the line from the file seem to be in a single line instead of being separated by a new line. output.txt A*B*C*D*E*F*G*H*I* Any pointer on how this can be avoided and is there a way i can do the pandas processing for each line efficiently without impacting performance within the post block itslef? -
Problem with sso-login in Django, Error GET /authorize/?token= HTTP/1.1"404 250
I am trying to run simple Django application. I have already installed simple-sso module in my local app. I tried but not solved. Following images tell us that error is occured when i run localserver. enter image description here enter image description here Following code is some of "settings.py": INSTALLED_APPS = [ 'ssoLogin.apps.ssoLoginConfig', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.sites', 'simple_sso.sso_server', ] ROOT_URLCONF = 'ssoLogin.urls' # Password validation # https://docs.djangoproject.com/en/4.1/ref/settings/#auth-password-validators AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] SSO_PRIVATE_KEY='ttVCo7bewsATjEPS7CNHd4tIk1ayyBKb1qbPk5DxWZiK4pvyLZQtnpinjPh6fWr3' SSO_PUBLIC_KEY='hGtAakAg7Sh3SffSs2obwAAflMuzbbLBUJUHpk6WrFnxhA9b78EHNoTOr0DsDho3' SSO_SERVER='http://127.0.0.1:8000/server' I used "simple-sso" module correctly according to documentation. I think everything of config(settings.py) is ok but i don't know urls and views are correct. Anyway this is my configuration in urls.py. Following code: from django.contrib import admin from django.urls import path, include, re_path from simple_sso.sso_server.server import Server from simple_sso.sso_client.client import Client from django.conf import settings test_client = Client(settings.SSO_SERVER, settings.SSO_PUBLIC_KEY, settings.SSO_PRIVATE_KEY) test_server = Server() urlpatterns = [ path('polls/', include('polls.urls')), path('admin/', admin.site.urls), re_path(r'^server/', include(test_server.get_urls())), re_path(r'^client/', include(test_client.get_urls())), ] Server and Client object imported correctly. I think client is working good but I dont know Server works. Maybe Server doesn't work correctly. Need to solve this. -

How to get the last record with a condition in Django
I am trying to get the last record of the table in Django with a condition. Model: Rooms id room staff_id 1 103 1000 2 105 1000 3 107 1555 the staff (number 1000) has two records, but I want to get just the last record of him. getStaffRecords = Rooms.objects.get(staff_id=1000) staffRoom = getStaffRecords.room and here I get an error, because I have more than one record. Error: get() returned more than one Rooms-- it returned 2! Anybody has a solution? I tried to use the methode like this: getStaffRecords = Rooms.objects.get(staff_id=1000).last() staffRoom = getStaffRecords.room but it didn't work, bcause in this case, "get" isn't recognized by Django. -
How to insert a value from a dict in a django annotation using each id from queryset
I have a simple dict containing ids with values associated like: {1:True, 2:False} I also have a queryset that have the same ids listed above in an atribute named user_id, but I need to add a new field to my objects on queryset with the values from my dict. Lets suppose the field I want to add is called is_admin, so I need to create a field on the object with id 1 on my queryset with the value True. What I tried to do is: my_dict= {1:True, 2:False} queryset = queryset.annotate( is_admin=Value(my_dict.get(F("user_id")), output_field=BooleanField()) ) But what happen is that I'm receiving null on is_admin. I tried to do the code below and it works: queryset = queryset.annotate( is_admin=Value(my_dict.get(1), output_field=BooleanField()) ) So I think is something wrong with my use of F expression. I will appreciate any help. -
how to have a TimeField with auto increment of 5 minutes (django)
I have a model in django that consists of these fields: device = models.CharField(max_length=150, null=True) time_received = models.TimeField(auto_now_add=True, null=True) display_time = [ i want it to have same hour as time_received , minute to be started at 00 and then have interval of 5 and finally second to be 00 ] the reason i want to do this , is to display time in an orderly manner. for example: device A is received at 8:01:20 ---> device A is shown as 8:00:00 device A is received at 8:07:22 ---> device A is shown as 8:05:00 one final note: I need to store both display time and received time in postgresql thanks for helping -

Wagtail: Limit choice dynamically based on current object
How can I limit the choices for the districtobject field in wagtail admin? class DistrictPage(Page): districtobject = models.ForeignKey(DistrictTranslated, on_delete=models.SET_NULL, null=True, blank=True) I know that I can use "limit_choices_to" for basic limitations with Q. But I want to use a more dynamic approach which allows me to use the "content" of the current object. (Like self.attribute ... etc) For example: def my_limit_function(self): 1. get parent page 2. read date from parent page and extract this information for a filter query -

Like would defining the schema of dynamic_columns somehow help ? Thanks in advance ! -
Django app with pandas processing not loading specific page on railway.app but runs fine locally, How to troubleshoot?
I am facing an issue where my Django application, that uses pandas processing code, is not loading a specific page when deployed on https://railway.app service and keeps giving an application server error, whereas it runs fine on a local server but takes more than 10-11 seconds for loading the specific page.

Reverse Inlines in Django Admin for Many to Many
Apologies if this has been asked before and my searches have not uncovered the solution. I'm looking to include admin inlines for two models. Django version is 4.1.4 class Book(models.Model): title = models.CharField(max_length=100) author_series = models.CharField(max_length=100, blank=True, null=True) series = models.ManyToManyField(Series) class Series(models.Model): name = models.CharField(max_length=100, blank=True, null=True) category = models.CharField(max_length=50) publisher = models.CharField(max_length=100,blank=True, null=True) I'm able to complete the forward relationship successfully using Model.field.through format: class SeriesInline(admin.TabularInline): model = Book.series.through class BookAdmin(admin.ModelAdmin): inlines = [SeriesInline,] but would like the reverse as well. class InlineSeriesBooks(admin.TabularInline): model = Series.book_set ... class SeriesAdmin(admin.ModelAdmin): ... inlines = [InlineSeriesBooks] I know model = Series.book_set is wrong but all the links seem to be suggesting the former through solution such as Django Admin, accessing reverse many to many. So far I have tried: Series.book_set = The value of 'biblio.admin.InlineSeriesBooks.model' must be a Model.

Django-Paypal - Trying to create an instance of my order and handle payments
I've been trying to use Paypal for my e-commerce project and have not got very far over the last few days. The issue I am having is that I have the Paypal SDK script in my checkout.html, which works fine and processes the payments as expected. What I want however, is to save the details of the order(and my shipping details in checkout.html) and create a new instance in my order model. I'm getting lost with this and not sure how to proceed, so any help would be much appreciated. Views.py: from django.shortcuts import render, redirect, reverse from django.contrib import messages from django.urls import reverse from profiles.models import UserProfile from django.views.decorators.csrf import csrf_exempt from .forms import OrderForm def checkout(request): bag = request.session.get('bag', {}) if not bag: messages.error(request, "There's nothing in your bag at the moment") return redirect(reverse('products:products_list')) order_form = OrderForm() # Attempt to prefill the form with any info the user maintains in # their profile if request.user.is_authenticated: profile = UserProfile.objects.get(user=request.user) order_form = OrderForm(initial={ 'first_name': profile.default_first_name, 'last_name': profile.default_last_name, 'email': profile.default_email, 'phone_number': profile.default_phone_number, 'country': profile.default_country, 'postcode': profile.default_postcode, 'city': profile.default_city, 'street_address_1': profile.default_street_address_1, 'street_address_2': profile.default_street_address_2, 'county': profile.default_county, }) template = 'checkout/checkout.html' success_url = 'https://8000-bend2525-therescuersp5-77ck14x21o2.ws-eu82.gitpod.io/checkout/thankyou' context = { 'order_form': order_form, 'success_url': success_url } return … -
Use of Django login_required decorator, how can I resume my paused view after the login succeeded?
As the title mentioned and please refer to code below. When the user is going to my_view_1 page, he will firstly be redirected to /login for a page of (user/password) input.

Dynamic Sidebar - How to add data from database to my sidebar automatically
This is my first project with Django. I am working on a scholarship system whereby the admin has the power to add new countries, which offer scholarships, to the system. Everything works well at the level of the database. I am able to add a new country and save it. However, it is automatically supposed to be added to the sidebar of the admin dashboard (templates). But this does not happen. Here is my views.py code for adding and saving a new country def add_country(request): user = request.user if request.method == 'POST': form = CountryForm(request.POST) if form.is_valid(): form.save() print(form.cleaned_data) return redirect('dashboard.html') #redirect to be changed else: form = CountryForm() return render(request, 'add-country.html', { "form":form }) class CountryListView(ListView): template_name = "base.html" models = Country context_object_name = "countrys" HTML CODE <li><a href="#" class="ttr-material-button"> <span class="ttr-icon"><i class="ti-email"></i></span> <span class="ttr-label">Countries</span> <span class="ttr-arrow-icon"><i class="fa fa-angle-down"></i></span> </a> <ul> {% for country in countrys %} <li><a href="#" class="ttr-material-button"><span class="ttr-label">{{ countrys.name }}</span></a </li> {% endfor %}
