GraphQL request made from React page to Django App blocked in the response
I am currently working on a personnal project which currently creates a GraphQL request in a react application and sends it to a Python django app in order to get the Response. The problem is when I ask for a GraphQL request from a react page, I get this anwser in the console.log : Access to fetch at 'http://localhost:8000/graphql/' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Django how to include all columns from one table, but a only subset of columns in a different table, using tbl.only?
I want to join a child table to the parent table, and return all columns from the child table (child.*), but only specific columns from a parent table (parent.foo, parent.bar), using only but not defer. Is there any syntax to issue a SQL similar to the following: select child.*, parent.foo, parent.bar from child join parent on child.parent_id = parent.id I do not want to use defer, because the parent table has even more columns than the child table. I currently have to spell out every column that I want using only: Child.objects.select_related('parent').only( 'id', 'name', 'creation_date', 'parent__foo', 'parent__bar' ).all() But I would like to include all the columns from Child. -
How to make view that uses a web scraper load faster
I have a view that outputs destination city results on a page. As part of the view, a web scraper searches for flight prices from the user's area to the destination city. After adding the web scraper to the view it now takes about 8 seconds to load. I was wondering how I can make the view load quicker, maybe with threading or another alternative. views.py def results(request, result1, result2, result3, result4, result5, result6, broad_variable1, broad_variable2, broad_variable3, specific_variable_dictionary, user_city): result1 = City.objects.filter(city=result1).first() result2 = City.objects.filter(city=result2).first() result3 = City.objects.filter(city=result3).first() result4 = City.objects.filter(city=result4).first() result5 = City.objects.filter(city=result5).first() result6 = City.objects.filter(city=result6).first() # get the first user selected specific variable value for each result result1_value1 = City.objects.filter(city=result1.city).values(broad_variable1)[0][broad_variable1] result2_value1 = City.objects.filter(city=result2.city).values(broad_variable1)[0][broad_variable1] result3_value1 = City.objects.filter(city=result3.city).values(broad_variable1)[0][broad_variable1] result4_value1 = City.objects.filter(city=result4.city).values(broad_variable1)[0][broad_variable1] result5_value1 = City.objects.filter(city=result5.city).values(broad_variable1)[0][broad_variable1] result6_value1 = City.objects.filter(city=result6.city).values(broad_variable1)[0][broad_variable1] # assign variables before referencing them result1_value2 = None result2_value2 = None result3_value2 = None result4_value2 = None result5_value2 = None result6_value2 = None # check if the user chose a second variable # get the second user selected specific variable value for each result if broad_variable2 != "Nothing": result1_value2 = City.objects.filter(city=result1.city).values(broad_variable2)[0][broad_variable2] result2_value2 = City.objects.filter(city=result2.city).values(broad_variable2)[0][broad_variable2] result3_value2 = City.objects.filter(city=result3.city).values(broad_variable2)[0][broad_variable2] result4_value2 = City.objects.filter(city=result4.city).values(broad_variable2)[0][broad_variable2] result5_value2 = City.objects.filter(city=result5.city).values(broad_variable2)[0][broad_variable2] result6_value2 = City.objects.filter(city=result6.city).values(broad_variable2)[0][broad_variable2] # assign variables before referencing them … -
filtering annotated-aggregated columns with django_filters
Assume I have a Customer Model which is related to an Order Model. I want to list customers and the Sum(or Count) of their orders between a date range. if there was no order in the given range for any customer the annotated column would be 0. if I use django_filters FilterSet it changes the main WHERE clause of the query so the row with no order wouldn't be displayed, but I want something like: .annotate( order_count=Count( 'customer_orders', filter=Q( customer_orders__create_time__gte=query_params.get('order_after') ) & Q( customer_orders__create_time__lte=query_params.get('order_before') ) ) ) is there a neat way to achieve this using django_filters FilterSet? -
Django serializer.is_valid() makes a call to different custom serializer method
I have a django test server. i want to POST user data and return Response with 'username' and 'Token' after successfull registration. In the following view, I also check if request.data['email'] already exists in Users model because i want it to behave as unique=True and it gives me unexpected results. I know this code is just a noob implementation all around and it doesnt bother me for now, but the more important thing for me is to understand WHY my code is giving these results. I believe a detailed answer will help me understand python so much better. Here is the View function inside views.py : @api_view(['POST']) @permission_classes((AllowAny,)) def Register(request): r={"username": "JohnDoeyy", "password": "Thisisapassword60!", "email": "test@test.com", "age": "50"} #r = request.data if not (r.get("username") and r.get("password") and r.get("email")): return Response("empty fields") serializer = UserSerializer(data=r) print("debug1") if request.method == 'POST': print("debug2") if serializer.is_valid() and serializer.validate_email(r.get("email")): #User.objects.filter(email=r.get("email")).exists(): print("is_valid:", serializer.is_valid()) try: print("debug3 before .save") serializer.save() #This does NOT work. print("debug3 after .save") token, created = Token.objects.get_or_create(user=serializer.instance) return Response({"user": serializer.validated_data['username'], "token": token.key}, status=status.HTTP_200_OK) except Exception as e: print("debugException" , e) return Response(str(e)) else: print("3") return Response("fail") Here is the serializer.py .

Access data across schemas in multi-tenant SaaS system using ORM
In our multi-tenant system (using Postgresql), we want to allow different tenants to "associate" with each other, and share some data. So if Tenant A is associated with Tenant B, when showing the shared data, our queries will need to get data from schema A AND schema B. I've found examples that show how to do so with straight Postgresql code; something like this: select * from S1.table1 UNION ALL select * from S2.table1 ...though ours would be much more complicated than that. But I've not found anything that explains how to do it with Django's ORM. In other words, how would I do the above with the query syntax we actually use in our site: queryset = MyTable.objects.filter(client_id__in=clients, status=Status.ACTIVE) -

So my django app looks like this -assaydash --dashboard (app) --members (app) --djangobackend (django project directory) --static --manage.py djangobackend/settings.py # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'dashboard.apps.DashboardConfig', 'members.apps.MembersConfig', ] djangobackend/urls.py urlpatterns = [ path('admin/', admin.site.urls, name='admin'), path('', include('dashboard.urls')), path('members/', include('django.contrib.auth.urls')), path('members/', include('members.urls')), ] members/urls.py urlpatterns = [ path('login_user', views.login_user, name="login"), path('logout_user', views.logout_user, name='logout'), ] members/views.py def login_user(request): if request.method == "POST": ... else: messages.success(request, ("There Was An Error Logging In, Try Again...")) return redirect('login') else: return render(request, 'authenticate/login.html', {}) def logout_user(request): logout(request) messages.success(request, ("You Were Logged Out!")) return redirect('home') index.html <a href="{% url 'login' %}" > <span class="d-sm-inline d-none">Sign In</span> </a> On the index page when i click on the a tag it shows me a debug page with path not found. Even though the url exists and i have included it in my main urls.py and i have added the app in the settings.py as well. please help and let me know what is wrong here. Notice that the url for name login was detected by the template but the path wasn't found. Also the other urls on the debug page are from my dashboard app which works fine
