source-detail error Django
We are running into this issue on tables that have foreign key constraints. For the table creating this issue, we copied the table data exactly with no constraints, just the data to a new table and everything worked fine. However, we want to use the table with the relationships and real constraints. Our models.py class NewsSerialiser(serializers.HyperlinkedModelSerializer): class Meta: model = News fields = ('news_id', 'news_source', 'news_title', 'news_description', 'news_publication_date', 'news_link') class NewsViewSet(viewsets.ModelViewSet): queryset = News.objects.all() serializer_class = NewsSerialiser Our URlS.py from django.conf.urls import url, include from django.contrib import admin from rest_framework import routers from note.note_api import NewsViewSet # Routers provide an easy way of automatically determining the URL conf. router = routers.DefaultRouter() router.register(r'notes', NewsViewSet, 'news') urlpatterns = router.urls The issue: Could not resolve URL for hyperlinked relationship using view name "source-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field. This error seems to be persistent on tables with foreign key constraints. Any advice or support is greatly appreciated. -

Reverse for 'favorite' with arguments '('',)' not found, following Bucky's Django tutorial on YouTube
I keep getting NoReverseMatch at /music/2/ error, and it's pointing me to the parent template that i'm inheriting from, base.html, but i can't find anything wrong with it.

Django tests not validating null=False constraint
I have a model with various fields. One of them is a CharField field = models.CharField(max_length=100, blank=False, null=False) Now when I create an object without this field in django tests class function 'setUpTestData', it doesnt give any error. If I add minLengthValidator to it then too it doesn't give any models.CharField(blank=False, null=False, max_length=100, validators=[MinLengthValidator(1)]) When I print it after the object is created it gives an empty string. I have another field: field2 = models.DateTimeField(blank=False, null=False) Now if I dont provide this data while creating the object, the test fails correctly. -

Connect Celery (Django) to RabbitMQ using SSL/TLS
This question is related to 49320158, I'll try to provide more details. I am trying to follow the tutorial First Step with Django but I need to add TLS/SSL to be able to connect to my RabbitMQ server v3.7.4.

How to show specific subcategory for a selected category in django

Django 2.0 - KeyError on View Test for Login
I'm having some problems testing my Django application. I have a view that gets information from a login form and then validate / authenticate the user, therefore redirecting him to a home view that displays various informations. I also put a control so that when the user is not logged in and he tries to insert the URL "/home" it redirects him to a errorpage view that displays an error template. This is the getLogin view, called when the form in the "login.html" page is submitted. I won't show the showLoginTemplate view because it basically does only that. def getLogin(request): if request.user.is_authenticated: ... # operations and context creation ... return render(request, 'myapp:home', context) else: if request.method == "POST": email = request.POST['mail'] password = request.POST['psw'] user = authenticate(request, username=email, password=password) if user is not None: auth_login(request, user) #the Django login renamed as auth_login ... # operations and context creation ... return redirect("/home", context) else: return redirect('/login/error', errorLogin='error') # shows the same page but with a login error message else: return redirect("myapp:errorpage") The home view: def home(request): if request.user.is_authenticated: # operations and context creation return render(request, 'users/home.html', context) else: return redirect("myapp:errorpage") #goes into a error page This is the test I'm trying … -
