Django Static Sitemap is not working gives error "Reverse for 'index' not found. 'index' is not a valid view function or pattern name."
I'm trying to implement a Static Sitemap for my app and I get the error "Reverse for 'index' not found. 'index' is not a valid view function or pattern name." even though these views are set up. What could cause this? I have no problem with dynamic sitemaps, just the static one. My views.py def front_page(request): return render(request, 'django_modules_testing_app/front_page.html', { }) def about_us(request): return render(request, 'ihgr_app/about_us.html', { }) def index(request): return render(request, 'django_modules_testing_app/index.html', { }) urls.py from django.urls import path from . import views from . import blocks from django.contrib.sitemaps.views import sitemap from .sitemaps import DjangoModulesTestingApp app_name = 'django_modules_testing_app' sitemaps = { 'main_app':DjangoModulesTestingApp } urlpatterns = [ path('', views.front_page, name='front_page'), path('', views.index, name='index'), path('', views.about_us, name='about_us'), path('category_details/<slug:slug>/', blocks.category_details, name='category_details'), path('search_website/', views.SearchWebsite.as_view(), name='search_website'), path('sitemap.xml', sitemap, {'sitemaps': sitemaps},name='django.contrib.sitemaps.views.sitemap') ] sitemaps.py from django.contrib.sitemaps import Sitemap from django.urls import reverse class StaticSitemap(Sitemap): changefreq = 'weekly' priority = 0.8 protocol = 'http' def items(self): return ['front_page','index','about_us'] def location(self, item): return reverse(item) -
Pydantic from_orm to load django model prefetch_related list field

How to redirect user from registration page to profile if user is already registered?
I am using Django class-based views for my project and trying to redirect user from registration view if he is already authenticated. I've done it already with LoginView and it was pretty simple and looked just like adding few lines of code: class Login(LoginView): authentication_form = CustomAuthenticationForm redirect_authenticated_user = True LOGIN_REDIRECT_URL = "core:profile" So after going to url for login, user ends up at his profile url. Absolutely simple and works perfectly. However, there is no CBV for registration and therefore CreateView should be used, which doesn`t have any attributes for checking if user is authenticated. The one method of doing something similar is UserPassesTestMixin, but it only gives me 403 Forbidden if user is authenticated, not redirect. Here is my current registration view: class Registration(UserPassesTestMixin, CreateView): form_class = RegistrationForm template_name = "registration/user_form.html" success_url = reverse_lazy("core:profile") def test_func(self): return self.request.user.is_anonymous def form_valid(self, form): print(self.kwargs) self.object = form.save(commit=True) self.object.is_active = True self.object.save() login(self.request, self.object, backend="core.auth_backend.AuthBackend") return HttpResponseRedirect(self.success_url) Maybe somebody have done it already? Would be very grateful for every advice! -
Calculating values from different Django Models
I have 2 similar django models, the difference between them is that one of them has a Foreign key with another model and the other is like a general Model. class Project: name = models.CharField(default='',max_length=100,verbose_name="name") class Article(models.Model): code = models.CharField(default='',max_length=20,verbose_name="Norma") name = models.TextField(default='',verbose_name="Denumire") project = models.ForeignKey(Project,on_delete=models.CASCADE,null=True) quantity = models.FloatField(default=0,verbose_name="Quantity") value = models.FloatField(default=0,verbose_name="Value") class BaseArticle(models.Model): code = models.CharField(default='',max_length=20,verbose_name="Norma") name = models.TextField(default='',verbose_name="Denumire") price = models.FloatField(default=0,verbose_name="Price") I want to calculate the value attribute from Article model, it should be like this: if article.code == basearticle.code: article.value = article.quantiy * basearticle.price How should I do this type of calculations? Should I write the logic in views.py? views.py: class ProjectDetail(LoginRequiredMixin, DetailView): template_name = "proiecte/project_detail.html" context_object_name = "projects" model = Project In the template I use {% for article in projects.article_set.all %} to generate a table that has all the attributes as headers. -
Django-filter is being ignored when query parameter value is non-existing
Code where problem occurs: class GameFilter(FilterSet): release = MultipleChoiceFilter(choices=Game.RELEASE_CHOICES, method='release_filter', widget=CSVWidget, required=True) def release_filter(self, queryset, name, releases): if releases: ... return queryset Lets say in my Game.RELEASE_CHOICES, one of my options is "2", this means this query is working for me http://localhost:8000/games/?release=2 In this case I can reach my breakpoint in release_filter method. BUT When I try to query this URL with non existing query parameter value http://localhost:8000/games/?release=2156 The release_filter is not being executed, cant reach breakpoint at all and all I get in return is: { "count": 0, "results": [], "page_size": 20 } What I would like to achieve is the filter being executed despite of non existing query parameter value. Is it possible? Thank you for all possible answers. -

How to render two views into one template using Django
fair to mention I'm just starting out with learning Django, and I could really use the help. To paint a clear picture, there are two API endpoints that I have to use and each one of them has to be rendered in the same template (HTML file) meaning they have to be in the same URL path as well, but I couldn't figure it out yet, I tried with both the function and class-based views but I got nowhere. views.py: ` class HomePage(TemplateView): template_name = 'home.html' def home(self, request): response = requests.get('https://api.covid19api.com/world/total').json() print('res',response.data) return render(request, 'home.html', {'response': response}) def other(self, request): response= requests.get('https://api.covid19api.com/country/south-africa/status/confirmed?from=2020-09-06T00:00:00Z&to=2020-09-11T00:00:00Z').json() return render(request, 'home.html', {'response': response}) ` urls.py: ` urlpatterns = [ path('home', HomePage.as_view(), name='home') ] ` home.html: ` {% extends '_base.html' %} {% block page_title %} Covid19 Statistics {% endblock %} {% block content %} <br> <br> <h3 class="text-center">World Total Statistics </h3> <br> <!-- <div class="container"> <div class="card-group"> <div class=" col-md-4"> <div class="card text-white bg-secondary mb-3" style="max-width: 20rem;"> <div class="card-body"> <h5 class="card-title text-center">Total Confirmed: {{response.TotalConfirmed}}</h5> </div> </div> </div> <div class=" col-md-4"> <div class="card text-white bg-secondary mb-3" style="max-width: 20rem;"> <div class="card-body"> <h5 class="card-title text-center">Total Deaths: {{response.TotalDeaths}}</h5> </div> </div> </div> <div class=" col-md-4"> <div class="card text-white bg-secondary mb-3" style="max-width: … -

Django SAML logout failing
In my Django project I use python3-saml to login with SSO. The login works like expected but the logout is failing with an error message 'No hostname defined'. I really don't know how to solve this as the only parameter passed to logout is the request and request is missing 'http_host' and 'server_name', read here.

How to write a get response for two different models data in one response sorted by date?
I have two models: class A(models.Model): ... date=models.DateTimeField(auto_add_now=True) ... class B(models.Model): ... date=models.DateTimeField(auto_add_now=True) ... Both have date field in them. Now I want to write a get response so that I can get both of these model's data from the database sorted by date on the frontend. I have written model serializers with all fields for them. Now in the get response, I have written something like this: A = A.objects.all() B = B.objects.all() aSerializer = A_serializer(A, many=True) bSerializer = B_serializer(B, many=True) all = aSerializer.data + bSerializer.data all = sorted(all, key=lambda item: item['date'],reverse=True) return Response(all) I think I will not be able to do pagination and other stuff with this.

Python coverage used in Django takes too long to execute even though it is run with --source flag option
I am using the Python package in combination with the Django testing framework and sometimes want to test only one app/directory/package stated in the coverage --source option. coverage run --source='custom_auth' manage.py test custom_auth.tests.TestAuth.test_authentication --keepdb Is this command the correct way to run only one test? I am also using --keepdb command to ignore recreating the database again. The test is executed in 0.147s, but something happens behind/before the test, and it takes about 3-5 minutes to start executing the test. -

How can I add html in iframe for django

Viewing all the Comments for a post using modal in Django
I am working on implementing a social media website using Django.I want the users to view all the comments posted for a post using modals of Twitter Bootstrap. The comments aren't displaying if there are more than 1 post in my database if I use modals. The logic which I have written works completely fine if I don't nest them inside a modal and display it directly on the webpage after the caption of the post.

How to make the dependant multiple choice field don't remove the previously selected choices from the choice field when depending field changes value?
I am working on Django forms. I have 2 choice fields, one is just a choice field and other one is multi choice field. The dropdown values of multi choice field depends upon the selection of choice field. Now, if I select a value from choice field, and then, selected 2-3 values from multi choice field regarding that earlier choice field, then, those selected values are displayed in choice field. Now my problem is, once I select the different choice from choice field, my previous selected choices from multi choice field gets deleted. One way is you can use .append() in jquery but the problem with this is it shows the choices from the previous selected choice field option. For eg: If by selecting previous choice value, I get 20 dropdown choices in multi select choice field (out of which I select 3 choices), then, by selecting some other choice value, I should be getting (let say only 5 choices), but I am getting 25 dropdown choices in multi select option. what I want is only 5 choices in drop down of multi select choice field with only 3 choices already present in the multi select choice field.. I hope … -

Display counter of likes per post with Django is not working
I want to get a variable on the views.py file that retrieves the list of likes for each post. So, then on the HTML file, I would use .count so I can get the number of items on the list and finally be displayed on the DOM. I first made classes on models.py. There, I have 3 classes: User, Post, and Like. User is from the default User class from Django. Post is a class that gets information about the post like the author, description, and timestamp. And on the Like class, I get the user and post. from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): pass class Post(models.Model): author = models.ForeignKey("User", on_delete=models.CASCADE, related_name="user") description = models.CharField(max_length=1000) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.id}: {self.author}" class Like (models.Model): user = models.ForeignKey("User", on_delete=models.CASCADE, default='', related_name="user_like") post = models.ForeignKey("Post", on_delete=models.CASCADE, default='', related_name="post_like") def __str__(self): return f"{self.id}:{self.user} likes {self.post}" Second, I made a function on views.py called "index". There, I get the whole list of posts (on the posts variable), then I tried to create the variable (totalLikesSinglePost), which should get the list of likes for each post. def index(request): posts = Post.objects.all().order_by("id").reverse() # Pagination Feature (OMIT THIS, IF YOU WANT) …
