Django test without vpn
I want to test my function, where I add a new object to a database and then (still in this function) the object is being sent to a server. The problem is that to send the object to a server I need to run VPN. I'm wondering is there a way to run this function in my test, but skip the line responsible for sending the object to the server, or somehow simulate this behavior? Currently, I'm not able to run my test because I'm getting Failed to establish a new connection: [Errno 110] Connection timed out My test looks like this: def test_create_ticket_POST_adds_new_ticket(self): response = self.client.post(self.create_ticket_url, { 'title': 'test title', 'description': 'test description', 'grant_id': 'test grant id', }) result_title = Ticket.objects.filter(owner=self.user).order_by('-last_update').first().title result_count = Ticket.objects.filter(owner=self.user).count() self.assertEquals(response.status_code, 302) self.assertEquals(result_title, 'test title') self.assertEquals(result_count, 1) And the post request is calling this function: @login_required @transaction.atomic def create_ticket(request): if request.method == 'POST': ticket_form = TicketForm(request.POST) tags_form = TagsForm(request.POST) attachments = AttachmentForm(request.POST, request.FILES) if ticket_form.is_valid() and attachments.is_valid() and tags_form.is_valid(): jira = JIRA(server=JIRA_URL, basic_auth=(jira_user, jira_password)) new_issue = add_issue(request, jira, ticket_form) add_attachments(request, jira, new_issue) set_tags(request, new_issue, tags_form) messages.info(request, _(f"Ticket {new_issue} has been created.")) return redirect(f'/tickets/{new_issue}/') else: ticket_form = TicketForm() tags_form = TagsForm() attachments = AttachmentForm(request.POST, request.FILES) return … -

Django in Google Cloud Run cant find /cloudsql socket
I have a dockerized django application which I've built, uploaded to GCR and then deployed as a google cloud run service. However, when starting up I get the following error (from the cloud run logs): psycopg2.OperationalError: could not connect to server: Connection refused Is the server running locally and accepting connections on Unix domain socket "/cloudsql/kingdoms-289503:us-west1:kingdomsdb/.s.PGSQL.5432"? My database settings for django look something like this: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'HOST': "/cloudsql/kingdoms-289503:us-west1:kingdomsdb", 'USER': "postgres", 'PASSWORD': "password", 'NAME': "postgres", } } And I've made sure to create the connection to the database From what I understand, cloud run is supposed to magically mount a at /cloudsql that django can use to connect to postgres, but the error implies that it's not being mounted. Is there an extra piece of configuration I would need to check to make sure that socket is there? Are there alternatives to connecting to cloudsql that don't involve this socket? -

How do I create a Django endpoint that receives JSON files?
I'm designing a Django endpoint that is supposed to receive a JSON file message from an API that sends texts.

Django REST Framework: HyperlinkedModelSerializer: ImproperlyConfigured error
I am trying to serialize my Django models using the HyperlinkedModelSerializer class from Django REST Framework. My application is a dictionary application. I defined the serializer class for a Definition model, DefinitionSerializer, as follows: class DefinitionSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Definition fields = ["id", "definition", "expression"] The Definition model is defined as follows: class Definition(models.Model): definition = models.CharField(max_length=256) I am trying to return the serialized data in my IndexView as follows: class IndexView(APIView): definitions = Definition.objects.all() serializer = DefinitionSerializer(definitions, context={"request": request}, many=True) return Response(serializer.data) Accessing that view, however, returns the following ImproperlyConfigured error: Could not resolve URL for hyperlinked relationship using view name "expression-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field. Does this error have to do with the fact that I am including slugs instead of primary keys in my URLs? For example, the URL associated with the "expression" field in the DefinitionSerializer is: app_name = "dictionary" path("define/<slug:slug>", views.ExpressionView.as_view(), name="expression") How can I make this work?
